Abstract
Contents using users' whole-body motion is now becoming popular, along with the spread of the low-cost whole-body motion capture systems. To present tactile signals to the whole body, latency of the system becomes a critical issue because it leads to spatial gap between the desired position and actual stimulation position, and also leads to spatially unsharp sensation. We have proposed to use linear resonant actuator as a high response vibrator, and use projection light to drive the vibrators so as to eliminate latency derived from PC-sensor communication. This paper reports result of the user study evaluating shape perception of the presented image by allowing free user motion. The result suggested that high-response vibrator and larger number of vibrators are both effective for achieving quick recognition.
