Abstract

We present clinical investigation results of a novel, wearable, orientation and mobility assistive device that uses radar technology. The radar device sends radio signals, detects objects in the environment, and conveys this information to the users by way of sound or vibration feedback. The aim of this investigation is to assess the effectiveness of the device for the visually impaired. During a two-week period of the investigation, 25 visually impaired participants used the device in their everyday activities and kept a diary of their experiences. The investigation included a training session as well as opening and closing interviews, including a standard QUEST 2.0 form to evaluate user satisfaction with assistive technology devices. 92 percent of the participants observed that the device improved their ability to perceive their environment, and 80 percent observed that it increased their confidence in independent mobility.
