1. Presenting Information on Wrist-Worn Point-Light Displays

Wearable devices with small form factors create a need for simple displays that present information through single light spots. What should these displays look like and how should they present information in daily life? In this work we built a light bracelet to explore this question. It consists of an LED stripe, which is controlled by Arduino components sewn onto an elastic armlet. In a preliminary user study we investigated how participants experienced self-designed light patterns in their daily lives. From the results we derived implications for the design of light patterns on wrist-worn displays.

2. Haptic Gaze Interaction

Wearable computing devices such as smartwatches and smart glasses are becoming more widely available. These devices present new interaction challenges, as the devices are usually small and the context of use sets limitations on available interaction modalities. We are exploring the use of gaze as input and haptics as output for wearable devices. This demonstration allows users to experience the combination of gaze input and haptic output in the use of a bus schedule application. Links to such applications could be embedded in the environment, much like paper schedules have been used in the past.

3. Low-Cost Latency Measurement System for Eye-Mouse Software

One of the important characteristics of a window- and gaze-contingent tool is the speed of reaction to the pointer or eye movements and the update delay—the so-called latency—of the contingent response. Here we demonstrate a handy possibility for measuring the latency of gaze-contingent or mouse-based software. We present a low-cost latency-measurement system that can be useful for studies that include eye-movement tracking tools. In our demonstration we use this system for measuring the latency of a gaze-contingent tool.

4. SID—Sensuousness, Interaction, and Participation

The SID project is about Snoezelen, a method based on the use of a multisensory environment (room) designed to awaken children’s interests. It offers them the opportunity to discover, explore, and experience at their own pace. It arouses curiosity and urges them to act, but it also offers a haven for relaxation. The purpose of the SID project is to further develop the Snoezelen concept, creating new opportunities for children with developmental disabilities to utilize today’s interactive possibilities. For example, by adding microphones, speakers, subwoofers and a computer to a waterbed, any movement in the waterbed becomes a bodily dialogue with its inner “wavescape” of evolving sound layers, vibrations, and even infrasonic kicks in the water. SID aims to develop new possibilities for sensuousness, interaction, and participation through an interactive multisensory environment.
