While autonomous wheelchairs reduce the burden on the passenger, the automation of the operation may make it difficult for the passenger to understand the route 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, it is important to present information to passengers about the future route of the wheelchair when obstacles or pedestrians approach from the front. In previous studies, only the distance and direction to the next turning point were presented. We propose a comfortable and easy-to-understand route presentation method that presents the direction and avoidance 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.
