Field testing of two electronic mobility aid devices for persons who are deaf-blind.

Conclusion: A high satisfaction score on QUEST does not necessarily imply that an assistive device is efficient in all circumstances; follow-up interviews provided important complementary information. Implications for Rehabilitation For people who are deaf-blind The Miniguide is reliable for detecting obstacles (vibrations are sent as a warning when approaching an obstacle). It is often used to know if taking the right route. It identifies entrances or openings (indicated by the vibrations stopping when pointing at a wall), which can replace the echo-location for blind persons with hearing impairments. The Miniguide helped to locate overhanging objects which are not detectable with a long cane. The Breeze can record landmarks for orientation and it possible to use those landmarks to go back alone later after taking a certain route for the first time with someone else. It helps to familiarize the person with new places. It can tell you where you are at any time. It helps with orientation and the participant also liked this feature because it helped with learning street names. The Miniguide and the Breeze were not efficient in all circumstances; there were some problems with the ergonomic (both), detecting snow banks (Miniguide), sensitiveness to the surroundings in crowded places (Miniguide) and exactitude for geo-localization (Breeze).
