Selection Above A Multitouch Surface


Above-surface interaction is a new and exciting topic in the field of human-computer interaction. It focuses on the design and evaluation of systems that humans can operate by moving their hands in the space above or in front interactive displays. While many technologies emerge that make such systems possible, much research is still needed to make this interaction as natural and effortless as possible. In this project we investigated the techniques for activating graphical widgets located in this above-surface space. We conducted a pair of studies that first elicited a set of gestures for above-table widget activation from a group of users and then evaluated and compared these gestures based on their performance.

    Multi-touch tables are becoming increasingly popular and much research is dedicated to developing suitable interaction paradigms. There also exist multiple techniques aimed at extending interactions into the hoverspace—the space directly above a multi-touch table. We propose a novel hover-space method that does not require any additional hardware or modification of existing vision-based multi-touch tables. Our prototype system was developed on a Diffused Surface Illumination (DSI) vision-based multi-touch set up, and uses light reflected from a person’s palm to estimate its position in 3D space above the table.
