“People can’t always come to the clinic for physiotherapy, and while they can be prescribed exercises to do in their own time, fluctuating motivation, pain, or fear of “getting it wrong” can easily lead to inaction, which stalls recovery and can aggravate symptoms.”
Physio24 wants to impress existing and potential investors by bringing a digital dimension to their successful physiotherapy practice. They want to introduce an app that empowers patients to manage their recovery process, through features like AR and VUI, gamefication, intuitive self-reporting, dashboard with progress bar and a home-training program for 4–5 weeks.

I could recognize the persona amongst my own friends, and can easily identify the pain points in classical physiotherapy. The real challenge will be to balance vision with reality in what can and will be the apps functions. Without any developers at hand.
I also found the brief contra productive: why make a design system before testing and deciding the technolgies in use with developers and costumers? In my experience, A rudimentary design is better than one that could be taken for final when discussing basic functions. The customer, and I, tend to discuss the wrong things otherwise.

In order to quickly identify painpoints, and to see the possibilities where customer goals an user goals can meet, the customer journey map is a great tool. Some touchpoints:

The design was IOS-based to make the user threshold very low (Jacob's law). I suggested a different take on the gamification, by using another visual style for the XR overlays than prevalent in games. This to keep the expression of a down to earth and natural practice that would fit any user’s everyday life, and thus have a high success rate. That the user could envision the physio program in her own daily movements would also make it realistic and achievable to her.
The colour scheme of the app should suggest light, cleanse and natural movements, in contrast to other XR assisted physiotherapy apps that has a darker, “techier”, interface. The animations in the app should make the user think of both muscles and flowing waves.

The customer asked for the usage of Augmented Reality (AR), Voice User Interface (VUI), haptics and or motion capture to ensure accuracy, both in reporting (by user) and in supervision (by practitioner).

The user flow provided here is for the stage “during app use” and more specifically, during set up for and usage of the XR-function. Making a user flow is a merciless practice that forces me to think through every possible interaction with the app. A most clever practice to save time and money.

A mid-fi mock-up of the same sub-stage as the userflow was made.

The prototype below is of one possible usage of VUI during an ongoing physio session. In this specific case, there is also a way of accessing VUI by just calling out the command, not having to use any hands.

Jacobs Law, according which users expect apps to work like other apps, made me design with IOS in mind. IOS is good for keeping the interface clean of irrelevant information. I matched the concept/visuals with the real world by placing activities in the users everyday life. To minimize cognitive load, I designed the app to give instructions step-by-step and I made sure the user would feel in control by giving cancelling options throughout. Existing xr-physio providers such as uplift.ai and sency.ai, gave me guidelines battling difficulties in designing hypothetical functions for a Mid-Fi design.
