Hatchwell
A mixed-reality physical therapy companion for arthroscopic rotator cuff recovery.
Overview
Hackathon: Johnson & Johnson × Mayo Clinic Innovation Challenge — designing the future of post-surgical care.
Hatchwell is a sensor-driven physical therapy companion app for patients recovering from rotator cuff surgery. It's designed to be a companion to physical therapy — ensuring at-home adherence and real-time feedback for patients.
The mixed-reality experience guides exercises and tracks reps and accuracy through hand tracking, while Arduino EMG biosensors monitor muscle fatigue and pain in real time. A companion app keeps patients and therapists connected with progress, feedback, and milestone celebrations.

How might we support post-surgical rotator cuff patients in maintaining consistent recovery routines while addressing both physical and emotional challenges at home?
Pain is more than physical
Post-surgery recovery is long and arduous, deeply affecting the emotional well-being of patients beyond just physical pain.
Pain prevents adherence
At-home exercise programs require motivated patients, but pain actively hinders the desire to continue prescribed routines.
Lack of real-time support
Once patients leave the clinic, therapists have no objective visibility into pain levels, fatigue, or exercise quality.
Vision
Our vision for Hatchwell sits at the intersection of market need, emerging technology, and patient outcomes.
70% non-adherence rate among 135k annual rotator cuff surgery patients
Integrate emerging XR and AI technologies into traditional solutions
Personalized recovery, higher adherence, and potential for new revenue streams

Solution
Personalized recovery — powered by Meta Quest 3 mixed reality and Arduino EMG biosensors. Hatchwell leases the headset directly to patients so there's no hardware barrier.
XR Device Leasing
Lease XR devices directly to patients, removing the hardware barrier and making immersive therapy accessible from home.
Objective Pain & Fatigue Tracking
Real-time sensor data tracks pain and fatigue beyond self-reports, giving therapists accurate visibility between sessions.
Virtual Pet & AI Assistant
A personalised companion (hatching egg → virtual pet) provides emotional support, celebrates milestones, and adapts to recovery progress.
Real-Time Exercise Demos
Guided XR exercise demonstrations with form feedback keep patients doing exercises correctly and safely at home.
Patient–Therapist Communication
Smooth, structured communication tools keep therapists informed and patients supported throughout the recovery journey.
Features
Six features that work together to make at-home recovery feel supported, trackable, and connected.
Gamified Onboarding
Patients personalise a virtual companion egg that hatches as they hit recovery milestones — making day one feel like a game, not a medical obligation.
Sensor-Tracked Workouts
Meta Quest 3 hand tracking captures reps and accuracy while Arduino EMG biosensors read muscle fatigue and pain in real time — removing guesswork from at-home exercises.
PT Logs & Live Feedback
Sessions are automatically logged and synced to the therapist. PTs can respond with real-time annotations and voice notes — keeping care continuous between clinic visits.
Calendar & Notes
Patients and PTs schedule upcoming sessions, attach session notes, and set reminders — keeping recovery organised and on track.
Milestones
Achievement badges tied to the companion's growth celebrate recovery wins big and small — reinforcing motivation throughout the journey.
Accessibility & Voice
Voice commands let patients find and start workouts hands-free. Captions, high-contrast mode, and adjustable motion intensity ensure the app works for everyone.
Design
Hatchwell's visual language balances clinical trustworthiness with gamified warmth — deep sage green as the brand anchor, soft warm neutrals for content surfaces, and cheerful per-exercise accent colors that give each session its own identity.

Egg Companion
Hatches and evolves as patients hit recovery milestones. Each personality feels uniquely theirs.
Octopus — Secret Companion
Unlocked after 6+ milestones. A reward for sustained commitment that turns long-term recovery into something worth celebrating.
Impact
Beyond recovery outcomes, Hatchwell creates measurable business value for clinics, therapists, and the broader healthcare system.
Additional Revenue Stream
By providing therapists with a new tool that can be rented out by patients for at-home use.
Retain Users
By extending the device's usability past the recovery stage, serving as a health tracking wearable.
Improve Patient Monitoring
By providing a scalable framework that could increase the patient-to-provider ratio.
Further Refinement
To system accuracy and approach, utilizing collected sensor data for continuous improvement.
Mixed reality experience
The mixed-reality experience patients step into on the Meta Quest 3 — guided exercises with hand-tracked rep counting and real-time EMG fatigue feedback.
