PTTV is an app that utilizes motion tracking technology to improve remote physical therapy experience during Covid.

In this three-week-project, we were challenged to design a mobile app that includes a future camera feature. With motion tracking which our team was interested in as our chosen feature, we decided to focus our use case on physical therapy whose area we had already noticed some problems in.

overview

It allows therapists to assign asynchronous and personalize modules according to the in-person appointment. Patients then can simply follow along the modules on TV and adjust their postures that have been scanned through phone camera.

Research

To gain basic process of a remote physical therapy and identify the problem space, we began to interview a physical therapist and gather more use cases through secondary research online.

Background

During a typical treatment, patients usually will meet with their Physical Therapists every 1-2 weeks through video calls.

After each session, PT assigns the patient some exercises to work on over the week until the next session.

Currently patients will have to do take-home exercises by themselves with little guidance, unlike exercising during sessions.

Difficulties

Needs

No tactile cue during remote treatment make it difficult for the patient to adjust posture.
Unable to see the patient's whole body due to camera angle.
It's harder to correct patients' posture.

Personalized remote program from PT to patients.
Visual feedback of exercise to help patients feel more confident and accurate at home.
Capable remote video capture for patients.

how might we

encourage patients who are going through remote physical therapy to stick with exercise treatment at home?

Use Case

With the identified problem, we made persona and storyboard to frame the problem and help visualize the use case.

Persona

Andrew, a skier suffering a sudden knee injury during COVID-19, and is hoping to effectively recover his knee without having to see his therapist in person often.

PRODUCT

To design for our use case, we decided to include three devices: desktop, phone, TV that fulfill different functions. We also integrated a cheap motion tracking stand for mobile phone, thinking it could be very useful to track patient's movement when doing exercises.

Desktop

According to the diagnosis from the in person appointment with the patient, physical therapist creates personalized weekly modules by adjusting settings to make each exercise tailored to the patients needs.

Phone

The phone app displays the patient’s weekly modules and current progress, detailing what exercises need to be done along with notes from the therapist.

The TV view opens when prompted by the phone app, guiding the patient through each exercise and correcting postures that are specific to the patient.

Reflection

We had a lot of fun exploring the motion tracking technology with the use case. At the same time we thought about future expansion of the app like including features of viewing reports analysis of patient's assignments and scheduling real-time remote appointment.
