In contrast to wearable gadgets, smart garments enable even more sensing and actuating possibilities due to closeness to the user`s body. Humans naturally use garments for several reasons such as protection or aesthetics. Many parts of the human body are naturally covered by garments which can be enriched with technology. […]

Smart Garments

Providing feedback mainly involves presenting visual or auditory cues to the user. These cues need to be perceived and understood and then the user is capable of reacting to them. While for most information retrieval tasks this works fine, several other tasks can be realized implicitly. Thus, the user just […]

Implicit Feedback

Current authentication systems strive to be as secure as possible. This poses several challenges to the user such as remembering complex alphanumerical passwords or changing the password every other month. Since average users currently need to remember many different passwords, making them secure against brute force attacks (i.e., making them […]

Usable Security

We explored different technologies and mechanisms to enable interaction in ubiquitous environments. Exploiting Thermal Reflection for Interactive Systems Thermal cameras have recently drawn the attention of HCI researchers as a new sensory system enabling novel interactive systems. They are robust to illumination changes and make it easy to separate human […]

Ubiquitous Interaction

The way we interact with technology has a huge impact on our cognitive processes. The interaction technique is one of the ways to influence the cognitive processes. Thus, different ways of interacting influences important factors such as recall or recognition of the displayed content. Cognitive Effects of Interactive Public Display […]

Cognitive Effects of Interactivity

3D displays are becoming more and more ubiquitous. While 3D displays cost roughly the same as their 2D counterparts, the understanding of how the 3rd dimension can be utilized for interaction is still limited. We explore different applications scenarios and mechanisms to exploit the 3rd dimension for interaction. Using Eye-Tracking […]

Interacting with 3D Displays

Many museums keep physical archives of artifacts and documents as well as digital repositories filled with directly related and meta information. Naturally, the number of objects filed away or being in remote locations surmounts the physical exhibition space. Many objects cannot be presented to the user and, thus, remain concealed. […]

Creative Engagement in Museums

In this project, we identify design guidelines for stereoscopic 3D (S3D) user interfaces and present the MirrorBox and the FrameBox, two user interface prototyping tools for S3D displays. As auto-stereoscopy becomes available for the mass market we believe the design of 3D UIs for devices, for example, mobile phones, public […]

Prototyping 3D Interfaces

After years in the lab, interactive public displays are finding their way into public spaces, shop windows, cinemas, and user`s home. They are equipped with a multitude of sensors as well as (multi-) touch surfaces allowing not only the audience to be sensed, but also their effectiveness to be measured. […]

Pervasive Displays

Driving a car is becoming increasingly complex. Many new features (e.g., for communication or entertainment) that can be used in addition to the primary task of driving a car increase the driver’s workload. Assessing the driver’s workload, however, is still a challenging task. A variety of means are explored which […]
