振動刺激を用いた自律移動車椅子の搭乗者への経路呈示

抄録

While autonomous wheelchairs reduce the burden on the passenger, the automation of the operation may make it difficult for the passenger to understand the path the wheelchair will take in the future. In this case, passengers may feel anxious or uncomfortable due to unexpected movements of the wheelchair. To reduce passengers' anxiety and discomfort, the authors it is important to present information to passengers about the future path of the wheelchair when multiple people approach from the front. In previous studies, only the direction of the wheelchair's turn was presented. We propose a comfortable and easy-to-understand path presentation method that presents the direction and width of the wheelchair's turn by changing the length of the haptic apparent motion according to the width of the wheelchair's turn. Preliminary simulated wheelchair driving experiments have confirmed the potential of the proposed method to improve passenger comfort.
