A Pilot Study Comparing Performance of Blind Participants on 12 Tasks, With and Without the ARIA Device

Sponsor: ARIA Research Pty Ltd

Summary

Summary The environment in which we live, play and travel is primarily built by and for people with sight. Navigating the sighted world with blindness can be exhausting, as it involves disorientation, social isolation, increased risk, frustration and inefficiency. Accessing timely information about the environment is necessary to navigate an efficient path of travel and reduce the effort involved in living with blindness. Numerous assistive technologies have been developed to improve access to information, and quality of life for people with blindness, however persistent technology limitations include affordability, unreliable internet connection, lag and limited battery life. Existing technologies can offer scene description or text-to-voice quite effectively when the user is standing still, but not quickly enough to gain benefit when on the move. Timely information is crucial at road crossings, where poor decisions can result in injury. Information lag or deficit also compounds travel fatigue due to time and energy wasted in searching, uncertainty and frustration. Blind users are often brought in to test new technologies or devices in controlled, clinical conditions, when it is too late to influence design. There is little evidence of testing these technologies in lived environments to understand the functional benefits for the blind population, partly because there is a dearth of available methods and measures to embrace the complexity of functional research. This study will test the safety, efficacy and usability of the ARIA Device in 12 varied research tasks undertaken by blind participants in clinical, social and outdoor lived environments, comparing ARIA performance with each participant's ordinary (non-ARIA) methods of undertaking the same tasks. The study uses an embedded mixed methods design with a qualitative priority, generating rich, precise data about what matters to participants and what they can do in diverse situations.
