Review mode lets the user select parts of a recording to measure. A guided setup helps make calibrating the trackers easy. The real-time view includes a full 3D visualization of leg motion. Data can be easily trimmed and exported for external use.


JIMI Orthopedic Diagnostic System: Turning academic research into an investigational product

JIMI (Joint Instability Measurement Interface) began as a tool developed at a university in Japan to measure orthopedic range of motion in patients recovering from ACL surgery. To advance to the next step of investigational use, our project was to build a full user experience around the proof-of-concept code.

Following a research phase, I assembled a set of personas and user flows that involved doctors, physical therapists, patients, and administrators. Building a solid picture of the day-to-day process of doctors and physical therapists measuring patients’ range of motion, this led to sketches of a simplified menu system focused on tracking, recording, and reviewing.

For the full UI, I designed a visual system that would be clear and appealing for both doctors and patients. I also worked closely with the dev team to find the best approach for the 3D visualization that would align with this system.
