History of Electronic Travel Aids

Over the past 40 years, a large body of technical literature has been published relating to the development and use of ultra sound as used by blind persons for orientation and mobility.

A number of articles are listed here that give an overview to such developments. As more articles are made available, they will be posted on this page so do check back from time-to-time.

A new list called SonicVision has been created for blind travelers who use a K-Sonar, KASPA or Sonicguide in their daily mobility. The purpose of the list is to exchange information and tips on using ultrasonic technology. It is a forum through which experienced travelers can help others make full use of ultrasonics in mobility and to share with others their wealth of expertise.
