The phenomenon of echolocation or using sonar to navigate the environment has been widely studied, though rarely taught to individuals who are blind or vision impaired (Kish 2003). This paper describes the essential content of an echolocation training package designed to assist orientation and mobility (O&M) instructors teach clients echolocation skills. This package will be trialled using volunteer participants who are clients of Guide Dogs NSW/ACT Australia and then refined based on an analysis of the resulting data. The training package includes seven modules containing background information, details of specific training areas, as well as O&M activities for people who are blind or vision impaired.
