An Empirical Study of a Decentralized Identity Wallet...
summary
A lab-style user study uses a prototype wallet app with 30 online participants on Android (v10+) and combines contextual inquiry, semi-structured interviews, a mental-model scale and the System Usability Scale to measure real tasks: connect, obtain a credential, build a proof. Findings show widespread confusion between decentralized identifiers (DIDs) and credentials, brittle QR-code and cross-device flows, password-entry keyboard issues, and unclear who controls data at key moments; overall usability reads SUS 71 and participants judge data minimization beyond the wallet itself.
