Nineteen million Americans have significant vision loss. Over 70% of these are not employed full-time, and more than a quarter live below the poverty line. Globally, there are 36 million blind people, but less than half use white canes or more costly commercial sensory substitutions. The quality of life for visually impaired people is hampered by the resultant lack of independence. To help alleviate these challenges this study reports on the development of a low-cost, open-source ultrasound-based navigational support system in the form of a wearable bracelet to allow people with the lost vision to navigate, orient themselves in their surroundings and avoid obstacles when moving. The system can be largely made with digitally distributed manufacturing using low-cost 3-D printing/milling. It conveys point-distance information by utilizing the natural active sensing approach and modulates measurements into haptic feedback with various vibration patterns within the four-meter range. It does not require complex calibrations and training, consists of the small number of available and inexpensive components, and can be used as an independent addition to traditional tools. Sighted blindfolded participants successfully demonstrated the device for nine primary everyday navigation and guidance tasks including indoor and outdoor navigation and avoiding collisions with other pedestrians.

“…The visually handicapped use the classic white cane to let them move independently until the smart stick for the blind was developed [9]. The conventional walking staff, on the other hand, can only aid them in identifying the difficulties in front of them.…”

Technology helps disabled people to get things done easier and in the case of visually impaired people, technology surely enables them to communicate to the surrounding environment independently. The purpose of this study is to propose design of smart walking shoe for the visually impaired people that incorporated with multi sensors. The main purpose of the proposed smart walking shoe is to guide the visually impaired people in a smarter way rather than using traditional method of walking stick. The smart walking shoe is proposed to be integrated with components such as moisture sensor, ultrasonic sensors, button, DF Player and speaker and Agile method will be used in the development process that involves Brainstorm, Design, Development, Quality Assurance and Deployment phase. The pre-evaluation testing shows that the smart walking shoe is shown to be effective as guiding tool to the visually impaired people to navigate independently. The future studies will be conducted by development and tested in actual environments.
