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

Summary

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.

Conditions

Interventions

DIAGNOSTIC_TEST

Interaction with Mock COVID-19 Rapid Antigen Test and Reference Surfaces

Participants will drop a saline solution with proteins onto the testing device. They will wait for it to dry and then report on the tactile sensation and overall feel of the surface. Feedback will include comparisons with the two reference surfaces. The primary goal is to determine the presence of mock COVID antigen in synthetic saliva using the device, which aligns with the goals of diagnostic testing.

DIAGNOSTIC_TEST

Biomechanical Measurements

Participants may have biomechanical measurements recorded, such as placing samples on a scale to measure downward force or using medical tape with a flexible wire to track finger motion. These measurements are likely aimed at objectively assessing how participants interact with the surfaces and their physical responses to tactile stimuli.

BEHAVIORAL

Psychophysical Tasks

Participants may alternatively be asked to perform standardized psychophysical tasks, such as Two Alternative Forced Choice tests, Odd-Man Out tests, or Magnitude Estimation tests. These tasks will provide structured comparisons and quantitative data on participants' perception and preferences regarding tactile qualities. The tasks are designed to evaluate participants' perception and preferences regarding tactile qualities, which involves behavioral responses to sensory stimuli.
