Validation of Texture Changing Coatings for At-Home Rapid Tests
This study is testing new ways to make at-home rapid tests, like those for COVID-19, accessible for people with low vision or blindness. Instead of relying on sight, these tests would show results through a change in texture that you can feel. Participants will interact with mock COVID-19 rapid antigen tests and reference surfaces, dropping a saline solution onto the device and reporting on the tactile (touch) sensation. Researchers will also gather feedback on how easy the tests are to use and how quickly participants can identify results. You may be eligible if you are 12 years or older, have been blind or visually impaired for over 10 years, regularly use tactile aids, and have a basic understanding of math plots. The study aims to see how successfully participants can identify positive or negative results and how quickly they can do so.
- Study design
- This is an interventional study with a planned enrollment of 20 participants. It is not specified if it is randomized or blinded.
- What's involved
- You will interact with mock rapid tests by dropping a solution and reporting on the feel of the surface. You may also have biomechanical measurements taken or perform psychophysical tasks.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your success rate, response time, and usability feedback will be measured throughout the study, which is expected to average one year.

What this trial measures
- Success rate of identifying whether the model test is positive or negativeThrough study completion, an average of 1 year
After familiarization, test trials will involve participants dropping a test solution onto the device with a test slab as well as positive and negative control slabs. They will be asked to identify whether the test is positive or negative, based on how the test slab feels to the touch compared to the controls. Participants will be evaluated on whether or not their response is correct. This will be repeated 10 times per participant to record a percentage of success.
- Response time of each trial of a participant identifying whether the model test is positive or negativeThrough study completion, an average of 1 year
A Qualtrics form will be used to record participant responses. Each trial will have its own page on the form during data collection. A trial will begin when the test administrator opens its page, and participants will be prompted to decide whether the device is displaying a positive or negative result. Once participants choose, the administrator will select their answers on the form, and the time to the last click will be recorded as their response time. This will be repeated 10 times.
- Usability feedbackThrough study completion, an average of 1 year
Subjects participating in the clinical trial will be invited to provide feedback on the usability and their preferences regarding the tactile aid introduced in the study. The assessment will be conducted using a modified Likert scale. This outcome aims to gather subjective experiences related to the use of new tactile aids throughout the trials. Throughout the study, participants will be consistently asked to comment on the usability and their preferences based on the tactile aid. This ongoing feedback will enable a comprehensive understanding of their experiences over time. Modified Likert Scale: Strongly Disagree Disagree Somewhat Disagree Neutral Somewhat Agree Agree Strongly Agree Extremely Agree Exceptionally Agree Title: Usability of Tactile Aid Min: 1 Max: 9 Higher the score, the better the outcome/ usability of the tactile aid.
- General feedbackThrough study completion, an average of 1 year
Subjects participating in the clinical trial will be invited to provide feedback on the usability and their preferences regarding the tactile aid introduced in the study. The assessment will be conducted by asking participants for general feedback on the device they used. Throughout the study, participants will be consistently asked to comment on the usability and their preferences based on the tactile aid. This ongoing feedback will enable a comprehensive understanding of their experiences over time.
