“…They are also prone to danger when walking along roadsides or crossing roads. Traveling is the biggest problem that low-vision and blind people face in their daily lives, and traditional navigation aids have significant limitations 3 . With the continuous increase in the number of blind people worldwide, the demand and requirements for modern intelligent navigation technology and tools are constantly increasing.…”

For a long time, blind or visually impaired people have relied on traditional aids such as canes or guide dogs to assist them in walking, but these aids have significant limitations. In order to help visually impaired individuals walk independently, this article improves the method of mapping images to sound in the literature, making it more applicable to blind navigation. By limiting the range and size of captured images, as well as improving the mapping relationship between captured images and transformed sound, the accuracy of the method has been improved from 84.2% to 88.8%, an increase of nearly 5% compared to the method in the literature, which can better assist in guiding the blind.

This paper reports the development of a specialized teleguidance-based navigation assistance system for the blind and the visually impaired. We present findings from a usability and user experience study conducted with 11 blind and visually impaired participants and a sighted caretaker. Participants sent live video feed of their field of view to the remote caretaker’s terminal from a smartphone camera attached to their chest. The caretaker used this video feed to guide them through indoor and outdoor navigation scenarios using a combination of haptic and voice-based communication. Haptic feedback was provided through vibrating actuators installed in the grip of a Smart Cane. Two haptic methods for directional guidance were tested: (1) two vibrating actuators to guide left and right movement and (2) a single vibrating actuator with differentiating vibration patterns for the same purpose. Users feedback was collected using a meCUE 2.0 standardized questionnaire, interviews, and group discussions. Participants’ perceptions toward the proposed navigation assistance system were positive. Blind participants preferred vibrational guidance with two actuators, while partially blind participants preferred the single actuator method. Familiarity with cane use and age were important factors in the choice of haptic methods by both blind and partially blind users. It was found that smartphone camera provided sufficient field of view for remote assistance; position and angle are nonetheless important considerations. Ultimately, more research is needed to confirm our preliminary findings. We also present an expanded evaluation model developed to carry out further research on assistive systems.
