Summary

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.

Detailed description

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.

Conditions

• Impaired Mobility
• Impaired Balance

Interventions

Type	Name	Description
DEVICE	Safer Seat Usability Trial	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.
