Test the usability, perceptions and acceptability of a computer monitor for participant diagnosed with ADRD and their caregiver who will program the applications specifically for each individual to help them remember activities of daily living. Goal is to keep participants in their homes longer and delay the need for institutional care
Dyads will use the R/S unit for 90 days, unless they request it to be removed prior to the end of the study. The research team (N. Fowler, PhD) will assess measures at baseline, 30 days, 60 days and 90 days. The primary outcome is a caregiver-assessed measure usability. Secondary measures include patient- assessed usability, and objective measures of frequency and type of use and computer literacy for both caregiver and the individual with ADRD22. Methods to collect user data (frequency, clicks, etc.) will be collected using tools developed in Aim 2. Desired outcome measures include (1) a mean score of \>80 ("Good") on the ten-item System Usability Scale (SUS) modified by IU investigators to accommodate older adults23; (2) a 80 percent acceptability rate on the Behavioral Intention 3-item scale; and, (3) at least 70 percent of participants using R/S a minimum of weekly. SUS is a validated ten-item scale (e.g., "Learning to use RememberStuff® was quick for me") using a five-point response scale (strongly disagree to strongly agree). Acceptance will be assessed as the mean score on a 3-item Satisfaction scale (e.g., "Rate your satisfied with RememberStuff®?"). This scale was adapted by IU Investigators for health IT and uses a seven-point response scale from 0 (not at all) to 6 (a great deal). Satisfaction is one of the canonical assessments for user acceptance of technology. SUS and Satisfaction questionnaires will be researcher-administered by study staff either face-to-face in the participant's homes, or via telephone. The mean and standard deviation for the composite SUS, acceptability rate and weekly usage will be calculated to a 90% confidence interval. Other secondary measures are adapted from Holden et al and are guided by the UTAUT221. Mean caregiver scores on the measures will also be compared to mean scores of the patient measures to examine congruence in usability and acceptability within the dyad.

Usability
Satisfaction and use of the monitor and apps using the Usability Scale, a validated 10-item scale sithe items suchs as "learning to use the calendar function was quick for me", using a 5 point response scale (0= strongly disagree to 5= strongly agree) Usability Scale, a validated 10-item scale (e.g. "Learning to use Calendar function was quick for me" using a 5-point response scale (0=strongly disagree to 5= strongly agree)
Time frame: through study completion, an average of 4 months
Acceptability
Acceptability satisfaction assessed by the VAS using a 3-item score: participants willingness to use "Assuming I have access to this technology today, I would use it". Participants' willingness to use in the future "I could imagine using this technology in the future". Perceived usefulness scale -Using this technology would be a relief for my daily care routine. "Altogether I think this technology would be useful in my daily care routine. Perecived ease of use scale- Interacting with the technology would not require a lot of mental effort "I think I would have the technology under control- Altogether I think the technology would be easy to use".
Time frame: through study completion, an average of 4 months
Intention of Use
The Behavioral Intention scale (e.g., "If it were up to you, to what extent would you want to use RememberStuff®?"). The 4-item scale uses a 7-point response scale from 0 (not at all) to 6 (a great deal). Behavioral intention is the canonical assessment for user acceptance of technology
Time frame: through study completion, an average of 4 months
Performance expectancy
7 items (e.g. "Thinking about using RememberStuff® in the past 90 days, to what extent do you find it useful in your daily life?") that use a 7-point response scale from 0 (not at all) to 6 (a great deal). 3-5 Semi-structured and open-ended questions about experience using the technology.
Time frame: through study completion, an average of 4 months
