ベルト型振動子アレイを用いた複数物体の位置情報提示

―同時に知覚可能な物体数の調査―

While there are many papers that focuses on transmitting location information such as distance and direction information of a single object using wearable vibrotactile devices, there are none that focuses on transmitting location information of multiple objects. In this paper, we conducted experiments to find out whether humans can understand and recognize information of the number of multiple moving objects (1～4) transmitted via vibrotactile stimulation. To do so, we built a vibrotactile waist belt and constructed an algorithm that changes vibration amplitude depending on the distance and direction of the target objects. As a result, we found that by using our method, participants have the tendency to be able to understand up to 3 moving objects.
