Brief Summary

Study is a randomized clinical trial evaluating the efficacy of novel mobile application technologies (including Seeing AI, Aira, and Supervision+) to improve quality of life in older adults with low vision by expanding community access and providing assistance with activities of daily living. Aira provides real-time remote personal assistance through a sighted Aira agent supplying direct feedback to assist with visual tasks. Seeing AI provides optical character recognition allowing any text to be read aloud, color identification, bar code reading, scene description, and facial recognition based on stored photos. Supervision + allows one to use the phone as a magnifier, providing magnification and contrast enhancement using the camera of the mobile phone. This study seeks to understand the potential of these technologies to improve daily activities, community participation, independence, and self-sufficiency in this group by examining a technological approach, which has not yet undergone rigorous investigation in a diverse population of older adults with visual impairment. Project objectives are to evaluate mobile applications in a wide range of visual disability, categorized into three groups: (1) mild to moderate visual acuity loss, (2) severe to profound visual acuity loss, and (3) legal blindness secondary to visual field loss. Participants are randomized to one of three intervention groups: (1) Supervision+ application, (2) Aira application, or (3) Seeing AI application for a period of 6 months. For the Aira intervention group, participants will be assigned either with 'restricted' access (current open access areas plus 30 minutes/month anywhere), or 'unrestricted' access (700 minutes), for a period of 3 months with a 3 month cross-over period. Participants may elect to continue the study for an additional 3 months during which time they have access to all 3 study mobile applications. Outcome measures include assessment of changes at three, six and nine months post-intervention for: visual ability, health state (including depression), self-efficacy, loneliness, life space, distances travelled from the home, and types of services obtained.

Outcome Measures

Primary Outcomes (1)

  • Visual ability change score

    The primary outcome measure is the person change score (before and after intervention), from the adaptive Massof Activity Inventory (AI) Questionnaire. The AI has an item bank of 510 items organized into 50 goals and 460 related visually-based tasks. Subscales range from 0 (not important) to 3 (very important). For those goals rated as important, subjects are asked to rate the task difficulty on subscales of 0 (impossible to do without help) to 5 (not difficult). Rasch analysis is employed to estimate visual ability from these difficulty ratings, on an interval scale. With Rasch analysis person measures are estimated, whereby a more positive person measure reflects greater visual ability. In this study, we will explore the the difference in person measures (i.e. change score) after the intervention at 3 and 6 months. A larger, more positive change score indicates greater visual ability since intervention.

    AI questionnaire will be administered three times over 6 months: baseline, 3-months post-intervention and 6-months post-intervention, and also 9 months post-intervention

Secondary Outcomes (6)

  • Health-related Quality of Life: SF-36

    will be administered three times over 6 months: baseline, 3-months post-intervention and 6-months post-intervention and also 9 months post-intervention

  • Beck Depression Inventory

    will be administered three times over 6 months: baseline, 3-months post-intervention and 6-months post-intervention and also 9 months post-intervention

  • Community Living: Life Space Questionnaire

    will be administered three times over 6 months: baseline, 3-months post-intervention and 6-months post-intervention and also 9 months post-intervention

  • 3-item UCLA Loneliness Scale

    will be administered three times over 6 months: baseline, 3-months post-intervention and 6-months post-intervention and also 9 months post-intervention

  • New General Self Efficacy Scale

    will be administered three times over 6 months: baseline, 3-months post-intervention and 6-months post-intervention and also 9 months post-intervention

  • +1 more secondary outcomes

Other Outcomes (3)

  • Telephone Interview of Cognitive Status (TICS)

    administered at time of enrollment

  • Psychosocial Impact of Assistive Devices Scale (PIADS)

    administered at 3-months post-intervention and 6-months post-intervention and also 9 months post-intervention

  • Aira Explorer Survey post intervention feedback

    6 months and also 9 months post-intervention
