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 …
