“…Many white canes with haptic feedback, called smart canes, have been proposed. Specifically, devices to assist the visually impaired, such as smart canes, provide information on obstacles and direction of travel to the visually impaired using vibration [8]- [10], force [11]- [13], and thermal cues [14] based on ultrasonic distance sensors, light detection and ranging (LiDAR), and global positioning system (GPS). However, these devices are intended to provide mobility assistance to the visually impaired and do not aim to support training.…”

For visually impaired people, a white cane is an important aid for obtaining information about the surrounding environment. Although the visually impaired should attend this training by orientation & mobility (O&M) specialists to learn proper cane technique, the number of specialists is limited. In our previous study, we developed a training system that enabled the visually impaired to learn white cane techniques using illusory pulling cues. In the previous prototype system, a cane grip-type device was developed with a built-in vibrator to generate asymmetric vibration stimuli, and illusory pulling cues were fed according to the position of the cane tip. Although the prototype system showed positive results, issues related to the lack of user-friendliness of the device associated with the wired drive and the impractical gripping method were observed. This study developed a more practical white-cane-type device for O&M training, envisioning independent training for the visually impaired, which improved the above-mentioned issues. Specifically, the device was wireless and had a vibration mechanism for the gripping method of the general cane technique, and its validity was demonstrated by evaluation experiments. In addition, the paper explains the usefulness of the device as per discussion with active O&M specialists. The results of the evaluation experiments indicated that the devices were implemented to satisfy the requirements for cane training.INDEX TERMS Illusory force sensation, touch technique, training system, white cane.

“…However, that does not necessarily mean that these devices are not suitable for such users. Of the outdoor studies, only [18] and [25] included B/VI users. The cane with vibrotactile or thermal feedback tested by [25] is a device that comes closest to a device B/VI users normally use.…”

“…A related approach was presented by Zeng et al [83], who augmented a white cane with an obstacle avoidance system based on 3D time-of-flight camera. Solutions for visually-impaired people also concerned various feedback modalities to convey information on users surroundings, such as haptic [25,61] and thermal [56] stimuli or abstract sonification [3,38,66]. While the design goals of Gapeau significantly differ from these systems, they informed our considerations on human recognition and feedback design.…”
