This is an initial usability assessment of a vehicle Seat Transfer device, the Safer Seat. The study will involve target end users (individuals with mobility impairments) trialing the Safer Seat and providing feedback via the Technology Acceptance Model Survey's Modified from Davis (1985) and brief qualitative interview.
This study investigates the initial usability of the Safer Seat vehicle transfer aid. Participants with impaired mobility, strength, or balance are being asked to transfer onto and off of a vehicle seat with and without the device to trial its usability. In addition, transfers are doing rated by a licensed occupational therapist according to the Physical Mobility Scale to determine if independence level is affected. Usability evaluation is being done both qualitatively and quantitatively using Technology Assessment Surveys and a semi-structured interview. Insight gained through this initial trial will be used to refine the design of the Safer Seat.

Participants will be asked to transfer onto/off of the vehicle seat using their normal method of transfer and then to trial transferring onto/off of a vehicle seat with the Safer Seat 1 one or more times with study personnel. Demographic data will be recorded for all participants to include age, sex, and type of mobility disability. Transfers will be observed by the research personnel and success in transfers will be recorded according to the Physical Mobility Scale. Usefulness and usability of the Safer Seat transfer experience will be reported by participants via Technology Acceptance Model Surveys; and participants will engage in a brief semi structured interview that will be audio recorded and transcribed via Microsoft Teams.

Physical Mobility Scale
Used to rate ability level in sit to stand and stand to sit transfers from 0 if not able to bear weight, to 5 if independent and not needing to use upper extremities for assistance.
Time frame: Day 1
Technology Acceptance Model Perceived Ease of Use, Usefulness, and Attitudes Toward Use questionnaires
Modified from Davis (1985) surveys to assess Perceived Ease of Use, Perceived Usability, and Attitudes Toward. Survey item responses on 5-item likert scale. Scoring progresses from Strongly Disagree (1) to Strongly Agree (5). For most items "Strongly Agree" indicase the individual favors the intervention. There are a few items phrased in a negative manner such that a response of "Strongly Disagree" indicates the individual favors the intervention; these items are reverse coded when scoring.
Time frame: Day 1
Semi structured interview
