Zhuo (Prince) Niu
Designer-Builder + Human Factors, AI Products, Prototyping, UX Research, and Design Engineering
Product designer working on human–AI interaction. Studying Human Factors Engineering at Tufts and building products people can use.
Helmline
Bring self-hosted agent progress and sensitive approvals to iPhone. Make the current task, permission scope, and host identity clear before the user acts.
- Focus
- Human–AI interaction · Permission design
- Build
- Independent design and SwiftUI development
- Delivery
- App Store 1.0 · Requires your own compatible Gateway
TrekAssist
Organize navigation and safety information for an outdoor guide with limited power and a low refresh rate. Team task testing exposed a hard-to-find Low Power Mode.
- Focus
- Human factors research · Device constraints
- Limits
- 800×600 e-ink display · Maximum 1 Hz refresh
- Evidence
- 9 participants · 6 prototype tasks
Porsche Digital Interface
Map navigation and voice flows around the driver’s limited attention, then translate confirmation, action, and recovery states into component specifications for engineering.
- Focus
- Multimodal HMI · Engineering handoff
- Context
- UX/UI internship · Porsche Asia Pacific
- Outcome
- 30% reduction in interface load time after iterative UI optimization
Shengjian

- Stage
- Team research prototype · Go / Tweak / Stop
- Evidence
- 3 participants · Panelist questionnaire tasks
Designing the seam between people and complex systems.
I’m Zhuo (Prince) Niu, a designer-builder focused on product design, human–AI interaction, and human factors. I’m studying Human Factors Engineering at Tufts, after finishing my Computer Engineering degree at Purdue.
I work on the details that make complex products understandable: clear prompts, timely feedback, deliberate permissions, and recoverable failures. I take an idea from its first usable flow through prototypes, testing, and enough implementation for someone to use it.
I independently designed, built, and released Helmline, an iPhone client for self-hosted AI agents, and SayIt, a macOS voice-to-text utility. I shipped UI work for Porsche Communication Management at Porsche Asia Pacific, built a BLE-paired posture-tracking app, designed and usability-tested TrekAssist, and built KnowledgeOS for durable project context.
I’m looking for product design, UX, and human factors roles, especially around AI products, refined UI/UX, and complex multimodal experiences.
