1 1 1 2 DCRA 1. 1.1 1) 1 Tactile Interface with Air Jets for Floating Images Aya Higuchi, 1 Nomin, 1 Sandor Markon 1 and Satoshi Maekawa 2 The new optical device DCRA can display floating images in free air Experience with interface systems using floating images shows the need to improve the user experience with tactile feedback. We report on the development of a system that uses air jets to give tactile stimulus to users interacting with the floating images. The system delivers compressed air pulses to the fingertips of a user touching the plane of the floating image. We have performed tests to find the range of air jet parameters that give the best user experience. 1 Fig. 1 Floating Touch Display. 1 Kobe Institute of Computing, Graduate School of Information Technology 2 Multimodal Communication Group, Universal Media Research Center, National Institute of Information and Communications Technology DCRA 1 c 2012 Information Processing Society of Japan
