We supplement a previously developed prototype wearable knee device, PT Viz, with an interface that displays at home session data and progress and allows patients to set goals and share their data with a therapist. We iteratively designed an interface using two paper prototypes by conducting a user study with 12 participants who had recently undergone knee surgery. We then confirmed participant preferences during a follow-up survey with the final prototype design, and implemented the PT Viz Mobile Android application to accompany PT Viz. We discovered that knee surgery patients thought viewing their progress and setting goals improved motivation to do prescribed exercises, and that patients wanted to involve their therapists in using the system. We hope that this system can both improve compliance and encourage concordance, and propose a field study to further investigate the usefulness of the system.born digitalmasters thesesengCopyright of the original work is retained by the author.goal settingwearable devicesuser interface designphysical therapyhuman-computer interactionPhysical therapy -- Technological innovationsMedical rehabilitation -- Technological innovationsKnee -- Surgery -- Patients -- RehabilitationUser interfaces (Computer systems)Communication in rehabilitationText
