Sensor web
A sensor web was an array of sensors that could be worn over ordinary clothing. Sensor webs were utilized by blind individuals in the 23rd century to help them live as though they were able to see. 

The blind Dr. Miranda Jones was one user of a sensor web in 2268. She stated to Captain James T. Kirk that she could perceive more with the information fed to her from the sensors than Kirk could with normal eyes. She could easily play games of accuracy such as tennis, determine exact distances down to the centimeter and detect heartbeats of those around her. In spite of this, there was disagreement as to whether the sensor web was sufficient for her to pilot a starship. ()
