A touchless gestural system for extended information access within a campus

In the last two decades, we have witnessed a growing spread of touchless interfaces, facilitated by higher performances of computational systems, as well as the increased availability of cheaper sensors and devices. Putting the focus on gestural input, several researchers and designers used Kinect-like devices to implement touchless gestural interfaces. The latter extends the possible deployments and usage of public interactive displays. For example, wall-sized displays may become interactive even if they are unreachable by touch. Moreover, billboard-sized displays may be placed in safe cases to avoid vandalism, while still maintaining their interactivity. Finally, people with temporary or permanent physical impairment (e.g. wheelchair users) may still comfortably interact with the display. Here we describe an information provision system allowing for touchless gestural interactions, along with a trial implementation within our University campus to test its efective-ness in a real setting. Our system is intended for use by students, lecturers and staf members, providing a captivating way to access news, lectures information, videos and more. We also report the results of an ongoing user study, defning a set of guidelines for future designs.
