Wall Display Experience Research

Faculty Advisor: Prof. Davide Bolchini

Meeting rooms, design studios, and laboratories in industry as well as academia are increasingly adopting ultra-large, Wall-Size Displays (WSD), and such adoption is expected only to increase due to the dropping cost of large display technology and the growing need to visualize large volumes of data.

Our long-term goal is to identify critical factors that are necessary to design next-generation interaction techniques to support collaboration around wall-size displays. We believe that a forward-looking vision of interacting with WSD needs to extend beyond a reactive adaption to existing technology, and must evolve from new, fundamental interaction principles.

Touchless interaction exposes a difference between the interaction space (of mid-air gestures) and the display space. This mismatch between the sensor’s tracking range and the system’s display range creates a gap between the system’s behavior and the user’s mental model. This happens when users perform a gesture that erroneously steps out of the WSD’s range. When this occurs, visual feedback typically disappears from the display, leaving users disoriented. We investigate how to support users to fluidly resume their touchless interactions, when they accidentally go off the WSD range.

We propose the Wall Display Experience Research (WADER) environment, a reliable, reusable and easily modifiable experimental environment that supports user studies on touchless interaction prototypes. The current deployment of WADER leverages off-the-shelf markerless sensors, Kinect™ and the 160” X 60”, ultra-high resolution, wall-sized display (15.3 million pixels) available at UITS in IUPUI. By varying design parameters, WADER enables batteries of experiments to be carried out very quickly and efficiently. It evaluates user experience by recording performance metrics.

To facilitate interaction and collaboration around ultra-high-resolution, Wall-Size Displays (WSD), post-WIMP interaction modes like touchless and multi-touch have opened up new, unprecedented opportunities. Yet to fully harness this potential, we still need to understand fundamental design factors for successful WSD experiences. Some of these include visual feedback for touchless interactions, novel interface affordances for at-a-distance, high-bandwidth input, and the techno-social ingredients supporting laid-back, relaxed collaboration around WSDs. This position paper highlights our progress in a long-term research program that examines these issues and spurs new, exciting research directions.

We conceptualized collaborative use Wall-sized Displays across different scenarios. To design WSD interaction techniques, we propose ways to model the user expereince, build a vocabulary for collaboration and envision four novel interaction paradigms.
