Human-Computer Interaction Group – Prof. Dr. Harald Reiterer Master Mulituser Navigation on Large-Scaled Interactive Surfaces Scenario Interactive surfaces like tabletops and walls often implement a panning and zooming navigation style, whenever only a limited amount of physical display space is available for navigating a larger virtual canvas of spatially distributed information. Mapping and planning applications which show vast amounts of visual data are one example for such panning and zooming User Interfaces. Current interaction techniques for navigation in spatial user interfaces are designed for single user interaction. However these techniques like pinching are applied to large scaled interactive surfaces as well. This leads to certain problems during a multi-user interaction. For instance when one user wants to zoom a map and the other user simultaneously wants to pan the spatial interface. Project Goal As a first step to solve this problem we implemented a body-driven interaction technique called Body Panning. On this basis a user can pan through a spatial user interface by adjusting her position at the table. We received a very good feedback at the ITS 2013. Thus there are a lot of suggestions and ideas for a future development.

Tracking ranges from counting steps to tracking the stages of sleep. Also calorie counters which make use of large calorie databases are part of self-monitoring. The calorie counters are based on the assumption that if we are aware of what we’re eating, we have the information to know how to eat healthier. Although this may be true it is very annoying to keep track of everything we eat. This information cannot be gathered automatically but has to be recorded manually, which leads to missing data and imprecisions. Furthermore to eat healthier a balanced nutrition should receive greater attention than counting calories. Project Goal Different nutrients actually impart different colors to the foods they’re in. Therefore a common ground in food science is that every meal should include colored foods like fruits and vegetables. Based on this knowledge an app can be developed to analyze meals with respect to the colors. An automatic image processing approach based on an image of the meal is intended. Furthermore a visualization has to be developed to give feedback about how colorful or balanced the meal is.

Tracking ranges from counting steps to tracking the stages of sleep. Also calorie counters which make use of large calorie databases are part of self-monitoring. In order to increase the effectivity of self-monitoring for changing the behavior of the users we do not only have to track the data but also have to give feedback. Most applications only provide simple forms of feedback such as showing the number of steps that one has to take to meet one’s goal. However more detailed insights about the behavior can be provided by unveiling relations between the gathered data (e.g., that meals at work are less healthy than at home). Project Goal Based on data about the nutrient of meals, tracked activities and some additional data like eating motives or time and location where meals took place visualizations and mechanism to analyze the data should be developed. The concepts should address the needs of end users and not the needs of expert data analysts. Therefore the concepts do not need to allow a detailed analysis, but have to provide a simple access to the gathered data.

In co-located (=same place) collaborative scenarios, egocentric navigation could to be particularly beneficial as it allows (explicit and implicit) interaction between the collaborators in the real world. Studies on this technique have shown cognitive advantages on an individual level. Little, however, is known regarding its suitability in collaborative scenarios. Project Goal Implement a study prototype that addresses the following research question: Which effects do egocentric input styles have on collaborative tasks when compared to non-egocentric input styles? Successful participation in „Usability Engineering: Evaluation“ is mandatory.

A clear structure has to be shaped and different instruments have to be combined to form an overarching impression conveying certain moods and feelings. To understand and visualise the arrangement of the movements for laymen is a challenging task. However, it is essential to present the underlying structure of the music if amateurs are to be integrated into the composition process. This system will visualise classical music consisting of several building blocks that can be listened to and partly arranged separately. Project Goal The outcome of this project is an interactive prototype that enables the users to contribute to composing a piece of classical music in a playful manner, combining different input modalities (such as tangibles or touch) with visual and audio output.

By building pipelines through different filters, data is manipulated in a visually appealing way detached from the technical background processes. Although Squidy offers a wide variety of settings, a live evaluation framework has not been integrated yet. Project Goal The goal of this project is to design a framework that uses Squidy to automatically analyse/plot data gathered in usability tests, e.g. a tapping test. The project should be based on scientific findings as found in related literature and be evaluated in user studies accordingly.

The following problems are amongst those that are yet to be analysed in detail when working with static peepholes (e.g. ZUIs, zoomable user interfaces): How does the size of touch displays (and accordingly the extend of body movement) impact spatial memory? To what extend is it influenced by the directness of interaction (remote, direct)? What other factors might have an influence and how can they be used to support user interaction and navigation? Project Goal As a first step, related literature is to be evaluated as a theoretical foundation. According to the research question, a test task is to be developed. An interactive prototype is to be implemented or adjusted in order to conduct a usability study for answering one of the above-mentioned research questions. The results need to be statistically analysed to add to the body of knowledge.

Gaze motion is not only extremely fast, but even works subconsciously most of the time, allowing for interesting insights to be gained during human-computer interaction. In cognitive psychology, recent study results hint at a correlation between (spatial) memory and eye movement towards relevant screen positions. Due to the subconscious nature of gaze motion, this connection could offer a fast and faithful feedback of users’ spontaneous reaction when asked about past events and locations. Project Goal As a first step, related literature is to be evaluated to establish a theoretical foundation of how HCI could make use of eye tracking in memory experiments. According to the research question(s), this also requires the development of one or several test tasks. An interactive prototype is to be implemented or adjusted in order to conduct a usability study for answering the research question(s). The results need to be statistically analysed and discussed accordingly.

Nowadays, a multitude of eye tracking systems offer the possibility of realising what had seemed to be impossible only a few years ago. Mobile or head-mounted trackers might be used either in a wide range to enable single components or in a more narrow field to control only a single component such as the head-up display. Menu selection, adjusting air conditioning or the like will then be possible, while the hands are free to control the steering wheel. Project Goal This project has two main goals to be worked on both theoretically and practically: 1) To research available eye tracking solutions and evaluate their (dis-)advantages. This includes the integration of the most suitable solution into a simple demonstrator cockpit by finding the optimal tracker position. 2) To develop the two mentioned usage scenarios (wide and narrow field of interaction) showing how eye tracking and gaze control may be used in automotive applications. Task internet, industry and literature research on eye-tracking systems (seminar presentation & paper) integration of eye tracker into prototypical automotive environment, evaluation of optimal position & usage scenarios, development of test application (project presentation & paper) evaluation of test set-up and test application, analysis and implications for future work (thesis & thesis defence) Contact Thomas Kälberer, Svenja Leifert Rooms: PZ 908, PZ 904 [email protected] [email protected] Announcement April 15th 2015
