Test the simplified remote—a remote with only the controls the person uses—on their familiar TV, one real viewing task at a time. Watch whether they can complete the task, recover from mistakes, and understand the buttons. Use pauses and brief hints, and record confusion and recovery rather than judging only speed. The goal is an individualized fit, not proof that one remote works for everyone.

Why test it with the person?
A remote can look physically manageable while still being difficult to use. In a 2018 outpatient study, one quarter of people with Alzheimer's disease used a simple TV remote incorrectly, and difficulty increased with dementia severity, according to the Neuropsychology Association of Japan. Read the study Direct testing matters because the person using the remote may notice barriers that a care partner misses.
In a Rica workshop with six people with mild-to-moderate dementia, participants identified excess buttons, unclear functions, and multiple remotes as problems. Treat the person's comments, hesitation, and workarounds as useful evidence. A remote that seems simple to someone else may still feel confusing or stressful to its intended user.
How should you prepare?
Keep the usual TV setup in place. Use the same television, seating position, and viewing arrangement the person normally encounters, because unfamiliar devices and interface changes require extra adjustment time. Explain that you are trying the remote, not testing the person.
Offer one brief task at a time and ask whether they would like you to read it aloud. Dementia usability research from University of Maryland researchers found that short scenarios, clear wording, larger text, line breaks, and verbal reading improved comprehension. Prepare tasks that reflect ordinary viewing:.
- Turn the TV on.
- Change to a familiar channel.
- Raise and lower the volume.
- Return to the intended function after a wrong press.
- Explain what a button does, if the person can do so comfortably.
What features should you test?
Start with the controls the individual actually uses. Hide or separate less-frequent functions rather than placing every option on the main surface; Rica workshop participants reported that crowded controls caused confusion and anxiety.
Compare button designs, especially: These features came from recommendations made by people with dementia in the Rica remote-control workshop. Read the Rica report Test whether the labels make sense during an actual task. A button can be easy to press yet difficult to identify, remember, or connect with the intended function.
- Large buttons with clear text and symbols.
- Different colors for volume and channel controls.
- Feedback that is visible or tactile when a button is pressed.
How should you run the test?
Give the task without a long explanation. For example, say, "Please make the sound louder," then allow the person to decide what to do. Do not rush.
Allow pauses, offer a small hint when needed, and give permission to stop or move on. Record what happened in simple notes: Completion time alone can mislead when mental fatigue or conversational support affects performance. University of Maryland researchers recommend recording confusion, error recovery, and comments alongside task completion. Read the usability study.
- Task completed independently.
- Task completed after a hint.
- Wrong button pressed.
- Person recovered after the error.
- Person appeared confused, tired, or anxious.
How do you decide whether the remote works?
Look for a pattern across the person's usual tasks. A promising layout lets them find the needed controls, perform familiar actions, and recover from an accidental press without becoming overwhelmed. If one feature causes repeated trouble, change that feature and test again.
You might reduce the visible buttons, separate infrequent functions, improve the label, or make volume and channel controls easier to distinguish. The evidence is encouraging but limited. The University of Maryland study involved 15 people with mild-to-moderate, early-stage dementia who already used technology, while the Rica workshop involved six participants; these findings should guide individualized testing, not support a universal design claim.
