  abstract      = {Co-located collaboration on large vertical screens has become technically feasible, but users are faced with
increased effort, or have to wear intrusive personal identifiers. Previous research on co-located collaboration has assumed
that all users perform exactly the same task (e.g., moving and resizing photos), or that they negotiate individual actions in
turns. However, there is limited user interface software that supports simultaneous performance of individual actions during
shared tasks (Fig. 1a). As a remedy, we have introduced multi-touch chords (Fig. 1b) and personal action windows (Fig. 1c) for
co-located collaboration on a large multi-touch vertical display. Instead of selecting an item in a fixed menu by reaching for
it, users work simultaneously on shared tasks by means of personal action windows, which are triggered by multi-touch chords
performed anywhere on the display. In order to evaluate the proposed technique with users, we introduced an experimental task,
which stands for the group dynamics that emerge during shared tasks on a large display. A grounded theory analysis of users'
behaviour provided insights into established co-located collaboration topics, such as conflict resolution strategies and space
negotiation. The main contribution of this work is the design and implementation of a novel seamless identification and
interaction technique that supports diverse multi-touch interactions by multiple users: multi-touch chord interaction along
with personal action windows.},

 abstract = {Electromyographic (EMG) signals play a key role in many clinical and\nbiomedical applications. They can be used for identifying patients with\nmuscular disabilities, assessing lower-back pain, kinesiology and motor\ncontrol. There are three common applications of the EMG signal: (1) to\ndetermine the activation timing of the muscle; (2) to estimate the force\nproduced by the muscle and (3) to analyze muscular fatigue through\nanalysis of the frequency spectrum of the signal. We have developed an\nEMG tool that was incorporated in an existing web-based biosignal\nacquisition and processing framework. This tool can be used on a\npost-processing environment and provides not only frequency and time\nparameters, but also an automatic detection of starting and ending times\nfor muscular voluntary contractions using a threshold-based algorithm\nwith the inclusion of the Teager-Kaiser energy operator. The algorithm\nfor the muscular voluntary contraction detection can also be reported\nafter a real-time acquisition, in order to discard possible outliers and\nsimultaneously compare activation times in different muscles. This tool\ncovers all known applications and allows a careful and detailed analysis\nof the EMG signal for both clinicians and researchers. The detection\nalgorithm works without user interference and is also user-independent.\nIt manages to detect muscular activations in an interactive process. The\nuser simply has to select the signal's time interval as input, and the\noutcomes are provided afterwards.},

have calculated the correlation coefficient between the dynamically detected pulses at the local maximums of the user activity
signal and the pulse of reference. We have found that users Replay activity significantly matches the important segments in
information-rich and visually complex videos, such as lecture, how-to, and documentary. The proposed signal processing of user
activity is complementary to previous work in content-based video retrieval and provides an additional user-based dimension for
modeling the semantics of a social video on the Web.},

to capture required information. In this research, we are describing a method for the analysis of implicit users' interactions
with a web video player, such as pause, play, and thirty-seconds skip or rewind. The results of our experiments indicated that
even the simple user heuristic of local maxima might effectively detect the same video-events, as indicated manually. Notably,
the proposed technique was more accurate in the detection of events that have a short duration, because those events motivated
increased user interaction in video hot-spots. The findings of this research provide evidence that we might be able to infer
semantics about a piece of unstructured data just from the way people actually use it.},

principles: 1) engage the students with narrative (hero, story), 2) employ familiar gameplay mechanics from popular video
games, 3) engage students into constructive trial and error game-play and 4) situate collaborative learning. As illustrated
examples we designed two math video games targeted to primary education students. The gameplay of the math video games embeds
addition operations in a seamless way, which has been inspired by that of classic platform games. In this way, the students are
adding numbers as part of popular gameplay mechanics and as a means to reach the video game objective, rather than as an end in
itself. The employment of well-defined principles in the design of math video games should facilitate the evaluation of
learning effectiveness by researchers. Moreover, educators can deploy alternative versions of the games in order to engage
students with diverse learning styles. For example, some students might be motived and benefited by narrative, while others by
collaboration, because it is unlikely that one type of serious video game might fit all learning styles. The proposed
principles are not meant to be an exhaustive list, but a starting point for extending the list and applying them in other cases
of serious video games beyond mathematics and learning.},

suggested itinerary from a digital map. We found that the preferred shortest path is significantly different to the suggested
one. Notably, the preffered paths were slightly longer than the suggested, but there was no effect in the trip duration because
there were fewer obstacles, such as cars. Since many pedestrians employ GPS enabled devices, the findings of this research
inform the development of mobile applications and the design of new subjective map layers for city dwellers.},

learn about an unstructured video just by analyzing the dynamics of how it is being used. In particular, we explore three
pillars of online user activity with video content: 1) Seeking patterns within a video is linked to interesting video segments,
2) Sharing patterns between users indicate that there is a correlation between social activity and popularity of a video, and
3) Editing of live events is automated through the synchronization of audio across multiple viewpoints of the same event.
Moreover, we present three complementary research methods in social video retrieval: Experimental replication of user activity
data and signal analysis, data mining and prediction on natural user activity data, and hybrid techniques that combine robust
content-based approaches with crowd sourcing of user gener- ated content. Finally, we suggest further research directions in
the combination of richer user- and content-modeling, because it provides an attractive solution to the personalization,
navigation, and social consumption of videos.},

We present a complete policy cycle that includes creating policy plans, securing stakeholders and public engagement, implementation, monitoring, and evaluating a particular policy model. ICT enabled tools can be deployed at various stages in this cycle, but they require an intuitive interface which can be supported by domainspecific languages (DSLs) as the means to express policy modelling aspects such as computational processes and computer-readable policy rules in the words of the domain expert. In order to evaluate the use of such languages, we present a real-world scenario from the urbanAPI project. We describe how DSLs for this scenario would look like.

making games on the learning performance and on the attitudes of the students. For this purpose, we designed a between groups
experiment with eighty students (12 to 13 years old). They formed three equivalent groups of twenty students each who practiced
with a serious game in three different ways. The first group played the storytelling game, the second played the same game but
with no story, and the third was engaged with modifying the game code. Finally, the last (control) group practiced
traditionally by solving exercises on paper. We found that girls with low grades benefited the most by playing the game and by
engaging with the code and that the game making group wishes to repeat the exercise. Further research should perform similar
studies with a focus on involving students in serious game modification, over longer periods of time and for additional
curriculum topics.},

  abstract      = {Sports tracking software for casual exercising has become popular with smart phone users who are concerned
about their health and fitness. Nevertheless, there is limited research on the user requirements for sports tracking software,
which needs to be fun and easy to use in order to appeal to a broad set of users. For this purpose, we employed a four-week
long experiment with five users who were asked to perform multiple workouts with two levels of gamification. The first
treatment stands for no gamification and the second treatment provided rich visual feedback, such as speed, distance, elapsed
time, map. At the end of the experiment, we asked users to describe the devices. Both devices included GPS sensor, so we also
measured the distance covered for each one of the workouts. We found that augmented feedback from mobile self-tracking devices
can promote working out, but there is also a trade-off of increased anxiety and disorientation. Thus, we suggest that sports
tracking software should be modest about how much and what type of visual information it provides to the user. In particular,
we found that the only piece of visual information that had an impact on performance was average speed, which indicates a
connection with gamication. Further research should consider additional levels of gamification beyond score, such as graphics,
sociability, rules.},

  abstract = {Contemporary digital maps provide an option for pedestrian navigation, but they do not account for subjective preferences in the calculation of the shortest path, which is usually provided in terms of absolute distance. For this purpose, we performed a controlled experiment with local pedestrians, who were asked to navigate from point A to point B in a fast manner. The pedestrians’ routes were recorded by means of a GPS device and then plotted on a map for comparison with suggested itinerary from a digital map. We found that the preferred shortest path is significantly different to the suggested one. Notably, the preffered paths were slightly longer than the suggested, but there was no effect in the trip duration because there were fewer obstacles, such as cars. Since many pedestrians employ GPS enabled devices, the findings of this research inform the development of mobile applications and the design of new subjective map layers for city dwellers.},

were collected. The results from the analyses highlight that the emotion of happiness dominated in the communication. Moreover,
the content included useful personal information and is connected with children's interactions (e.g., number of views and of
recipients). In addition, children generally preferred VideoPal to email because they felt that it was easier and has more

 abstract = {Automatic recognition of human actions from video has been studied for many years. Although still very difficult in uncontrolled scenarios, it has been successful in more restricted settings (e.g., fixed viewpoint, no occlusions) with recognition rates approaching 100%. However, the best-performing methods are complex and computationally-demanding and thus not well-suited for real-time deployments. This paper proposes to leverage the Kinect camera for close-range gesture recognition using two methods. Both methods use feature vectors that are derived from the skeleton model provided by the Kinect SDK in real-time. Although both methods perform nearest-neighbor classification, one method does this in the space of features using the Euclidean distance metric, while the other method does this in the space of feature covariances using a log-Euclidean metric. Both methods recognize 8 hand gestures in real time achieving correct-classification rates of over 99% on a dataset of 20 subjects but the method based on Euclidean distance requires feature-vector collections to be of the same size, is sensitive to temporal misalignment, and has higher computation and storage requirements.},

	Abstract = {The World of Warcraft (WoW) (Blizzard Entertainment, 2004) massively multiplayer online role playing game (MMORPG) provides users with extensive control over its user interface (UI), which has inspired the emergence of a large community devoted to developing UI modifications (UI modding). Through investigation of the members of the community of those who design and use UI modifications for WoW, we gather information that may aid in the creation of communities dedicated to modifying the interfaces of other software packages. The goal of this paper is to study the effect that user created interfaces have had on WoW and its community of users. To achieve this goal, we issued an online survey to WoW players that investigated four aspects of the community: (R1) the backgrounds of its members, (R2) their attitudes towards
modifications and the community itself, (R3) their use of UI modifications, (R4) the characteristics and motivations of users who create and share modifications. The survey results represented numerous unique viewpoints and shed light on the varied nature of the UIM
community of those who design and use WoW modifications. The results suggest that the interface of a videogame is best developed in concert with its players via UI modifications because the users of the system may be the best equipped to design or customize the interface to meet their needs. Since every user may have unique ideas about the perfect interface for a software package, perhaps the only way one could ever satisfy all users is to give them the ability to create their own.},

pause, skip). Moreover, we implemented an algorithm that selects representative thumbnails. Finally, we populated the system
with data from an experiment with nine users. We found that the VideoSkip system indexes video content by leveraging implicit
users interactions, such as pause and thirty seconds skip. Our early findings point toward improvements of the web video player
and its thumbnail generation technique. The VideSkip system could compliment content-based algorithms, in order to achieve
efficient video-indexing in difficult videos, such as lectures or sports.},

by a controlled experiment. A total of 60 lyceum students (between 15 and 16 years old) participated in a between-groups
evaluation that compared the performance of three levels of interactivity (passive guided tour, paper-based, mobile-based), as
well as the perceptions among the groups. The results indicate that the mobile-based student group had higher performance in
the post-assessment when compared with the paper-based one. Notably, perceived interest for the game affects students'
perceptions for a future museum visit. Further research should consider the effects of higher-fidelity types of mobile
applications, such as 3D graphics, as well as augmented-reality games.},

evaluating interacting art installations. These are: 1) data collection method; 2) user interaction; 3) social interaction; 4)
issues about children; 5) message comprehension. We suggest that these factors can inform engineering practices for engaging

They have become learning institutions in their own right as they enhance their exhibits to leverage the opportunities offered by ICT tools; thereby providing a wider (cognitive) thinking space for their online visitors. Although the role of museums in supporting the formal education of the general population is usually associated with visits to a physical museum, the online museum environment is now playing an important part in providing more information to people, as well as further enriching their life-long learning experiences.

  Abstract                 = {In this paper an interdisciplinary study towards the development of adaptive lighting environments is presented, involving experts from the domains of human-system interaction, activity and context recognition, and system architecture design. The goal of this work is to explore the design options and technical challenges for adaptive lighting environments from an interdisciplinary perspective, in the domain of 'office environments'. Two significant contributions are made with regard to the implementation of adaptive lighting in office environments and an evaluation method that is in line with the interdisciplinary approach. A qualitative study was performed with experts from three different disciplines to extrapolate joint research areas for further investigation. Our main findings are described with regard to the three involved fields.},

In most approaches, the modalities are independently considered and the effect of one modality on the other, which we call inter-modal influence (e.g. speech or head pose modifying the facial appearance) is not modeled. In this paper, we describe a system that utilizes context from the presence of such inter-modal influences to recognize facial expressions. To do so, we use 2-D contextual masks which are activated within the facial expression recognition pipeline depending on the prevailing context.

basic access to touch events, but there is no support for advanced user interface widgets, such as chords. For this purpose, we
extended the open-source PyMT toolkit with an architecture that supports alternative user interaction strategies with chorded
menus. In addition, we built a multi-user extension that supports chords for two or more users. Chords could be used for having
user-aware MT applications. Our toolkit is open source and has been designed as a widget that could be integrated into broader
interaction frameworks for multi-touch screens.},

Previous research in user-based techniques has assumed an extra effort from the users, such as video replies, comments, tags,
and annotations. We have developed and evaluated the SocialSkip system, which improves sense making of web videos by
visualizing the simplest form of user interactions with video, such as pause, and seek. In contrast to previous stand-alone
implementations, the SocialSkip system employs a web-video player and cloud-based resources (application logic, database,
content). The system was validated with two user studies, which provided several hundreds of user interactions with five types
of web video (sports, comedy, lecture, documentary, how-to). We found that seeking activity within web video is reversely
proportional to how interesting the video is. Moreover, we suggest that if the users are actively seeking for information
within a video (e.g., lecture, how-to), then the user activity graph could be associated with the semantics of the video.
Finally, SocialSkip provides an open architecture for collaborative contributions to the analysis of the user activity data, in
a fashion similar to the TRECVID workshop series.},

user enjoyment. In the first experiment (a target acquisition task with two moving targets), the MT was more efficient than the
mouse. Surprisingly, we found that the reduced accuracy of MT did not affect the perceived usability, or the enjoyment of the
users. In the second experiment (a multiple shapes docking task), the MT was again more efficient and enjoying than the mouse.
In the two-user condition, we found that performance and enjoyment was always higher than the single-user conditions,
regardless of input device and task. Besides the quantitative results, we observed that users employed diverse interaction
strategies in the MT condition, such as bi-manual input. The proposed tasks and the results support the use of MT in
entertainment applications (multimedia and video-games), collaborative work, and scientific visualizations with complex data.},

  abstract = {The introduction and wide adoption of small and powerful mobile computers, such as smart phones and tablets, has raised the opportunity of employing them into multi-device scenarios and blending the distinction between input and output devices. In particular, the partnership between a personal device and a shared one provides two possible output screens. Then, one significant research issue is to balance the visual interface between two devices with advanced output abilities. Do the devices compete or cooperate for the attention and the benefit of the user? Most notably, how multi-device interaction is appreciated in multi-user scenarios? Previous research has raised and considered the above research issues and questions for dual screen set-ups in the work environment. In our research, we are exploring multi-device user interface configurations in the context of a leisure environment and for entertainment applications. Our objective is to provide interaction possibilities that are more than the sum of the parts.},

human–computer interaction (HCI) research findings, there is limited investigation in the context of leisure activities, such

provide particular directions to be considered in further research in social and mobile TV.},

through a shared screen. The development process begins with the design of interaction between the system and the participants,
as well as between the participants themselves. Then we map the interaction design concepts into multimedia and architectural

better than those offered by the wireless operator. Simple metaphors from the real world and consistent visual depictions
across different handsets performed best for mobile phone icons, while abstract concepts had the lowest recognition rates.
Designers of mobile phone icons have to balance a trade-off between the need of the manufacturers and wireless operators to
differentiate their offerings through branding, and the need of the consumers for a familiar visual language in mobile phone
menus.},

These phrases were coded into 14 items and then clustered into 4 factors. The second stage of the study, which was addressed to
131 Facebook users, the factor analysis that was conducted, verified the validity of the four factors: Social Connection,
Social Network Surfing, Wasting Time, Using Applications. Finally, the results were analyzed in order to interpret each
factor's impact and to enable a comparison with previous research regarding the same subject. These showed how users continue
to primarily regard Facebook as a means of socializing with other users, but also the extent to which Facebook has become a
part of their daily routine, something that is indicated by the impact of the "Wasting Time" factor. Further research can be
conducted by addressing a greater number of users, selected with a less random manner and possibly with a different (cultural,
economical etc.) background.},

To recognize control signs in the gestures, we used a single channel EMG sensor positioned on the inside of the forearm. In addition to common statistical features such as variance, mean value, and standard deviation, we also calculated features from the time and frequency domain including Fourier variance, region length, zerocrosses, occurrences, etc. For realizing real-time classification assuring acceptable recognition accuracy, we combined two simple linear classifiers (k-NN and Bayes) in decision level fusion. Overall, a recognition accuracy of 94% was achieved by using the combined classifier with a selected feature set. The performance of the interfacing system was evaluated through 40 test sessions with 30 subjects using an RC Car. Instead of using a remote control unit, the car was controlled by four different gestures performed with one hand. In addition, we conducted a study to investigate the controllability and ease of use of the interface and the employed gestures.},

  abstract      = {At first glance, the notion of social interactive television seems to be a tautology. Television watching
has always been a social activity. People watch television together in their living rooms, and outside their homes they talk
about last night's football match; and even call each other to recommend an interesting program. Unfortunately, until recently,
research on social interactive television has been scarce. One limiting factor for the development of innovative services for
the home is the interactive technology behind user interaction, which was limited to the remote control. Fortunately, a number
of studies concentrate on extending interactive methods, for example by using contextual information. This article reviews the
state of the art in these two directions: the social aspects of television and user interaction. We conclude with a research
agenda for further research, which might transform current interactive television services into shared experiences.},

  abstract      = {Interactive Television (ITV) applications gratify entertainment needs and leisure activities in a relaxed
domestic context. Then, the mentality of efficiency and task completion implied by many user interface heuristics may not be
suitable for design and expert evaluation of ITV. In line with the contemporary movement towards the design of the user
experience of computing systems, a set of design principles for ITV applications has been developed. Instead of information
technology, the field of communication science was explored, which has accumulated an extensive theory of TV usage and viewer
behavior. For the empirical validation, the principles were employed in the design of an interactive music TV application. The
results suggest that a small set of generic principles could support the systematic design of ITV applications and produce a
design rationale that is traceable and comparable to alternative solutions, during the process of early product development. In
addition, the principles could be refined into specific guidelines and further employed to support expert evaluation
techniques.},

Previous works on social television systems belong to two categories: 1) studies on how collocated groups of viewers socialize
while watching TV, and 2) studies on novel Social TV applications (e.g. experimental set-ups) and devices (e.g. ambient
displays) that provide technological support for TV sociability over a distance. The main shortcoming of those studies is that
they have not considered the dominant contemporary method of Social TV. Early adopters of technology have been watching and
sharing video online. We employed cultural probes in order to gain in-depth information about the social aspect of video
sharing on the internet. Our sample consisted of six heavy users of internet video, watching an average of at least one hour of
internet video a day. In particular, we explored how they are integrating video into their daily social communication
practices. We found that internet video is shared and discussed with distant friends. Moreover, the results of the study
indicate several opportunities and threats for the development of integrated mass and interpersonal communication applications
and services.},

consider two basic issues: What is interactive TV research? Can it help us reinvent the practices of creating, sharing and
watching TV? We survey the literature and identify three concepts that have been inherent in interactive TV research: 1)
interactive TV as content creation, 2) interactive TV as a content and experience sharing process, and 3) interactive TV as
control of audiovisual content. We propose this simple taxonomy (create-share-control) as an evolutionary step over the
traditional hierarchical produce-distribute-consume paradigm. Moreover, we highlight the importance of sociability in all
phases of the create-share-control model.},

enduring and meaningful exchanges. Shared encounters are the glue of social networks and have a socializing effect in terms of
mutual understanding, empathy, respect and thus tolerance towards others. The quality and characteristics of such encounters
are affected by the setting, or situation in which they occur. In a world shaped by communication technologies, non-place-based
networks often coexist alongside to the traditional local face-to-face social networks. As these multiple and distinct on and
off-line communities tend to carry out their activities in more and more distinct and sophisticated spaces, a lack of coherency
and fragmentation emerges in the sense of a shared space of community. Open public space with its streets, parks and squares
plays an important role in providing space for shared encounters among and between these coexisting networks. Mobile and
ubiquitous technologies enable social encounters located in public space, albeit not confined to fixed settings, whilst also
offering sharing of experiences from non-place based networks. We will look at how to create or support the conditions for
meaningful and persisting shared encounters. In particular we propose to explore how technologies can be appropriated for
shared interactions that can occur spontaneously and playfully and in doing so re-inhabit and connect place-based social
networks.},

interfaces. In this paper, universal access in ambient intelligence is modeled after the use of TV in everyday life. Instead of
considering television only as a content medium and the focus of user activity, an alternative approach is to consider
television use as a secondary function to other activities, such as socializing, domestic chores, leisure pursuits. For this
purpose, the requirements for ambient user interactivity with TV are organized in a small set of design principles. The design
principles have been selected, analyzed and synthesized from readings in previous works on media and ethnographic studies about
television, and everyday life. It is suggested that universal access in ambient intelligence is promoted by considering design
principles such as opportunistic interaction, user participation, group interactions, and multiple levels of attention to the
user interface. Finally, the principles have been tested in the design of a user interface for interactive music television.
This preliminary case suggests that the proposed principles facilitate the design of user interfaces that blend seamlessly with
everyday life.},

  abstract      = {A diverse user population employs interactive TV (ITV) applications in a leisure context for entertainment
purposes. The traditional user interface (UI) evaluation paradigm involving efficiency and task completion may not be adequate
for the assessment of such applications. In this paper, we argue that unless ITV applications are evaluated with consideration
for the ordinary TV viewer, they are going to be appropriate only for the computer literate user, thus excluding the TV
audience from easy access to information society services. The field of media studies has accumulated an extensive theory of TV
and associated methods. We applied the corresponding findings in the domain of ITV to examine how universal access to ITV
applications can be obtained. By combining these results with emerging affective quality theories for interactive products, we
propose a UI evaluation framework for ITV applications.},

 abstract = {Emergency response requires strategic assessment of risks, decisions, and communications that are time critical while requiring teams of individuals to have fast access to large volumes of complex information and technologies that enable tightly coordinated work. The access to this information by crisis management teams in emergency operations centers can be facilitated through various human-computer interfaces. Unfortunately, these interfaces are hard to use, require extensive training, and often impede rather than support teamwork. Dialogue-enabled devices, based on natural, multimodal interfaces, have the potential of making a variety of information technology tools accessible during crisis management. This paper establishes the importance of multimodal interfaces in various aspects of crisis management and explores many issues in realizing successful speech-gesture driven, dialogue-enabled interfaces for crisis management.This paper is organized in five parts. The first part discusses the needs of crisis management that can be potentially met by the development of appropriate interfaces. The second part discusses the issues related to the design and development of multimodal interfaces in the context of crisis management. The third part discusses the state of the art in both the theories and practices involving these human-computer interfaces. In particular it describes the evolution and implementation details of two representative systems, Crisis Management (XISM) and Dialog Assisted Visual Environment for Geoinformation (DAVE_G). The fourth part speculates on the short-term and long-term research directions that will help addressing the outstanding challenges in interfaces that support dialogue and collaboration. Finally, the fifth part concludes the paper.},

is a model that aids the organization and dynamic presentation of television programming from a combination of live broadcasts,
prerecorded content and Internet resources at each set-top box. In this paper, we describe two applications that have been used
to validate the virtual channel model. We have employed the properties of the virtual channel model into the design of
personalized television advertising and interactive music video clip programming. Finally, we describe an ActiveX control that

 abstract = {The goal of oru research is to develop computer systems that support designers' collective creativity; such systems support individual creative aspects in design through the use of representations created by others in the community. We have developed two systems, IAM-eMMa and EVIDII, that both aim at supporting designers in finding visual images that would be useful for their creative design task. IAM-eMMa uses knowledge-based rules, which are constructed by other designers, to retrieve images related to a design task, and infers the underlying "rationale" when a designer chooses one of the images. EVIDII allows designers to associate affective words and oimages, and then shows several visual representations of the relationships among designers, images and words. By observing designers interacting with the two systems, we have identified that systems for supporting collective creativity need to be based on design knowledge that: (1) is contextualized; (2) is respectable and trustful; and (3) enables "appropriatoin" of a design task.},
