Overview
Athena is a human motion analytics system designed to bridge the gap between in-clinic rehabilitation and remote athletic recovery. During a 4-month internship at Theorema Systems, I served as the lead UI/UX designer on the mobile product, taking the app from early discovery and sensor mapping to high-fidelity prototypes and a scalable design system.
How It Works
The Athena ecosystem unites wearable hardware, real-time spatial visualization, and remote clinical oversight into a single seamless loop:
1.
Sensor Configuration
Wearable sensors are calibrated and attached to specific joints.
2.
Digital Twin Mapping
Real-time motion capture displays the athlete’s movement live on-screen.
3.
Automated Capture
As the athlete performs exercises, the mobile app logs movement automatically.
4.
Therapist Dashboard
Data syncs to a web portal where therapists review metrics, give feedback and assign new sessions.
The Problem
Setting up motion sensors for remote physiotherapy was historically complex, repetitive, and prone to severe user error. Athletes frequently struggled to identify which physical sensor belonged on which joint and whether calibration was successful. This resulted in corrupted motion data, skewed progress tracking, and constant reliance on live therapist intervention.
The Design Direction
Designing a low-friction setup process that builds user confidence and ensures data integrity.
The Solution: Core Features
SOLUTION 1
Smart Sensor Configuration
Light-assisted hardware pairing eliminates placement guesswork and speeds up session setup.
SOLUTION 2
Real-Time Visual Feedback & Digital Twin
Live 3D avatars give immediate spatial validation, reducing the need for live therapist supervision.
SOLUTION 3
Automated Data Capture & Progress Analytics
Comparative motion empowers athletes to track symmetry and self-correct over time.
Design System & Developer Handoff
To keep the UI consistent across complex states (such as bluetooth pairing, low battery, and live streaming errors), I built a component-driven design system from the ground up. This standardized typography, color-coded status states, and interaction patterns—dramatically reducing design debt and ensuring frictionless handoffs with engineering teams.
The Impact
Here is what the app helps with in the ecosystem:
Clients receive real-time feedback and accurate motion data, helping them correct form and stay consistent with exercises, leading to better recovery results.
Visual feedback, progress tracking, and personalized notes keep users motivated and accountable throughout their rehabilitation journey.
Automated tracking and visual data reduce the need for constant supervision, allowing physiotherapists to focus on analyzing progress and tailoring treatment.
Athletes can complete guided sessions from home, reducing dependency on in-person visits and expanding access to care, especially in remote areas.
Learning Outcomes
Designing in the Unknown: Building for first-time users, hardware constraints, and a system that’s still taking shape.
When hardware meets software, it’s crucial to observe real user behavior and design around how people actually interact with the device, not how we want them to.
Design with the MVP in mind and build with flexibility. My solution should solve immediate needs while staying adaptable for future growth and changing requirements.
