CASE STUDY #1
ui // ux // industrial design
LimbForge is software for configuring and manufacturing 3D printed prosthetics. It enables clinicians to spend less time customizing devices, lowers materials and equipment operation costs, simplifies supply chains, and delivers ultra lightweight, culturally-contextual prostheses to populations who need them most. Once a prosthetic design is in LimbForge, it can be configured to fit nearly any human anatomy on Earth.
As lead designer, I conceived and implemented all UX and UI features for the software, led product research and managed relationships with contributing partners.
3D models of upper-limb prosthetics were designed in Fusion 360, Autodesk CAD software that allows for parametric geometry. Using a plugin script, 3D printable files (STL's) for every parametric variation were exported and loaded onto AWS.
Using a web-based platform, users enter specific measurements of a patient's intact limb. The software mines AWS for the best size matches and loads the file to the web-app for 3D printing.

PROOF OF CONCEPT
The POC demonstrated how a user will be able to see real-time modifications to a CAD model in the web-app.

We consulted with patients, local clinicians, professional prosthetists, global health experts and software specialists.
Insight: In the developing world, people do not have access to advanced technology
Action: Create a software system that the patient navigates with the clinician.
Insight: Literacy varies.
Action: Make software visually based.
Insight: Instant feed back is critical to demonstrating (to patient and clinician) how the technology works.
Action: Stop using AWS and replace with live web-based modeling (Autodesk open API).
Inside our patient's home, we observed her daily routines and tracked the activities a prosthetic would assist her with.
