AI tools demonstrate effectiveness at helping people with vision loss complete tasks
Key takeaways:
- AI apps and glasses had varying effectiveness in 14 daily living tasks but were well received by participants.
- AI technologies were most useful for text-related tasks.
People with vision loss, or PVL, were satisfied with the use of AI technologies to complete vision-related activities of daily living, according to a cross-sectional, counterbalanced, crossover study.
Such findings could ultimately help “to guide technology recommendations based on PVL clinical characteristics and functional needs,” the study authors noted.

“With advancements in computing power and digital imaging, the integration of AI into portable tools such as smart glasses and smartphone apps is shaping the future of assistive technology,” study author William H. Seiple, PhD, chief research officer at Lighthouse Guild and a research professor at NYU Grossman School of Medicine, said in a Lighthouse Guild press release.
According to Seiple and colleagues, there are issues regarding the use of AI in people with vision loss, such as types of information and sensors needed, the nature of the user interface and what algorithm should be used, and “proposed solutions have been appearing rapidly.”
Yet, “the functionality of AI in the hands of PVL must be objectively quantified,” they wrote in Translational Vision Science & Technology.
In the analysis, Seiple and colleagues evaluated two smart glasses, the OrCam and Envision Glasses, and two AI apps, Google Lookout and Seeing AI, based on 14 daily living activities in 25 people with vision loss. These technologies were referred to as assistive artificial intelligence implementations (AAIIs).
The categories of tasks evaluated included:
- searching and identifying, such as identifying a color, describing a room or finding a person;
- reading text, such as reading an article, street sign, medicine bottle or handwriting; and
- reading text in columns, such as text in a TV guide or table of contents.
The data on AAII effectiveness were collected across five 90-minute sessions, including a baseline session, in which usual refraction and no AI was used for tasks, and four sessions in which one of the four AAIIs was used.
Seiple and colleagues reported that the odds ratios for completing text tasks were substantially higher than at baseline in five of the six tasks with OrCam and all six tasks with Envision, Seeing AI and Lookout.
The impact of the AAIIs on the six searching and identifying tasks were more varied. The odds ratios for completing a task were better than at baseline for five tasks with Seeing AI, four tasks with Envision, three tasks with OrCam and two tasks with Lookout.
Participants expressed satisfaction with all the AAIIs, with a median Likert score of 5 out of 5 for Seeing AI, 4 out of 5 for OrCam, and 3 out of 5 for Envision and Lookout.
The researchers acknowledged some study limitations, such as potential volunteer bias. They also did not know if outcomes would have been different if participants used the AAIIs for an extended amount of time at home.
“These technologies hold tremendous promise for creating a more inclusive, accessible world for PVL,” Seiple said in the release.
