Blessing Mangwiro | AI Product Designer

Safety-Critical AI • Multimodal Interaction • Human-AI Trust

The interface is the contract between human judgment and machine output. I design for moments where AI failure has real consequences — assistive systems for blind pedestrians, privacy-preserving computer vision, multimodal spatial computing. Recent work: 100% task completion in controlled usability testing, 99%+ detection accuracy, validated across safety-critical contexts.

Prototype Type Safety-critical mobile guidance UI

Validation Mode Usability-tested interaction evidence

System Focus Vision + guidance + confirmation loop

Currently

AI Product Designer

MS in Human-Computer Interaction (Iowa State, 3.95 GPA). I specialise in safety-critical AI systems, non-visual interaction design, and the hard problem of making machine output legible to humans under pressure. Every case study on this site includes product strategy, success metrics, and explicit build/don’t-build decisions.
