Validation of Texture Changing Coatings for Use in At-Home Rapid Tests

Status unconfirmed · Not applicable

Conditions studied: Vision, Low, Blindness

In brief

At-home testing is an important part of mitigating the spread of COVID-19, but these tests are not accessible to people with low vision or blindness. Instead of adapting to a technology originally built for sighted people, investigators propose a no-power version that reports test results through a texture change, which people can feel by touch. This platform could be used not only for COVID, but also for other diagnostics, and will promote the independence and privacy for people with low vision or blindness by removing the need for human assistance or an internet connection.
