What was done
The authors reviewed published functional studies evaluating the BrainPort V100 Vision Aid, an FDA-approved and CE-marked sensory substitution device that converts camera images into electrotactile stimulation on the tongue. The review assessed technology design, impediments to performance assessment, functional visual task outcomes, and the role of user training and rehabilitation.
What was found
The abstract reports no numerical data. Qualitatively, it reports that blind users can learn to perceive light, identify and localize simple objects, recognize short words, and detect the motion and orientation of objects, provided they undergo adequate rehabilitation and training.
Why it matters
It provides an overview of functional capabilities for a non-invasive assistive device intended to augment traditional mobility aids like white canes and guide dogs for people who are blind.
Limits
As a narrative review, it does not provide systematic inclusion criteria, risk-of-bias assessments, or quantitative effect sizes. Device utility relies heavily on extensive training regimens, and it functions as a sensory supplement rather than a complete visual restoration.
