Clinical Trial 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

Type	Measure	Description	Time frame	Safety issue
Other	Telephone Interview of Cognitive Status (TICS)	questionnaire; with subscales 0 to 1, with higher scores indicating greater cognitive ability.	administered at time of enrollment
Other	Psychosocial Impact of Assistive Devices Scale (PIADS)	questionnaire; with subscales from -3 to 3, higher scores indicate greater affinity of a particular factor to assistive technology use.	administered at 3-months post-intervention and 6-months post-intervention and also 9 months post-intervention
Other	Aira Explorer Survey post intervention feedback	(specific to those participants randomized to Aira); questionnaire, with subscales ranging from 0 to 10, higher scores indicate stronger agreement or helpfulness of the Aira App.	6 months and also 9 months post-intervention
Primary	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	Health-related Quality of Life: SF-36	questionnaire; scale ranges from 1 (excellent) to 5 (poor), with higher values indicating greater difficulty.	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	Beck Depression Inventory	questionnaire; subscales range from 0 to 3, with higher values indicating greater depression.	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	Community Living: Life Space Questionnaire	questionnaire; subscales range from 1 (Yes) to 2 (No), with a higher total value indicating a more restricted life space.	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	3-item UCLA Loneliness Scale	questionnaire; subscales range from 1 to 3, with a high value indicating increased loneliness.	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	New General Self Efficacy Scale	questionnaire; subscales range from 1 to 5, with a higher value indicating greater self-efficacy.	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	App usage frequency	App usage in minutes.	at 3 months post-intervention and 6 months post intervention and also 9 months post-intervention
