Pointing in the Physical World for Light Source Selection


We focus on the selection of light sources in the physical world. Their selection is challenging for the user, since numerous Light- Emitting Diodes (LEDs) can be embedded into various materials as well as environments, thus creating high densities of interactive objects. In this paper, we describe an innovative technique for light sources selection based on the pointing paradigm, that is, allowing interaction at a distance. To address the limitations of the pointing paradigm (e.g., aiming at distant and/or small targets), we design a two-step pointing technique: a rough aiming with an arm pointing gesture and a disambiguation mechanism with a wrist rolling gesture. Feedbacks lean on the various capacities of LED lights. We expect that our technique is well suited for the selection task in dense environments, no matter how small and how distant the targeted light sources are. We also expect that the technique supports an efficient interaction based on proprioception and muscular memory properties for expert users, who may perform the two interaction steps by a single combined gesture for better performance.
