In this article, I have summarized the required features in electronic sensory systems for the visually impaired (ESSVI) development and described how we have addressed these features at the Department of Electrical Electronic and System Engineering (DIEES). The "Committee on Vision" document on electronic travel aids explored the needs of the visually impaired (VI) and the features of devices that are needed to support them in their daily activities. High-performance devices can improve the life quality of visually impaired people. Many aids have already been developed that extend their "range of observation". Design engineers who understand the individual needs of the VI can build effective aids.
