Scenario-based Exploration of Integrating Radar Sensing into Everyday Objects for Free-Hand Television Control

Abstract

We address gesture input for TV control, for which we examine mid-air free-hand interactions that can be detected via radar sensing. We adopt a scenario-based design approach to explore possible locations from the living room where to integrate radar sensors, e.g., in the TV set, the couch armrest, or the user's smartphone, and we contribute a four-level taxonomy of locations relative to the TV set, the user, personal robot assistants, and the living room environment, respectively. We also present preliminary results about an interactive system using a 15-antenna ultra-wideband 3D radar, for which we implemented a dictionary of six directional swipe gestures for the control of dichotomous TV system functions.
