AAA contrast intent
The visual system targets WCAG 2.1 Level AAA contrast with high-contrast and text-size controls available from the welcome state.
Guided. Calm.
Accessible.
Designing a secure, intuitive biometric registration flow for first-time users at a standing self-service kiosk.
Product design / Service choreography
01 / Service risk
Trust starts before
the first touch.
Biometric kiosks sit at the intersection of service operations, trust, hardware, and physical behavior. Users are standing in formal, time-sensitive environments and may be uncertain about sensitive-data capture.
The interface has to coordinate a clear digital instruction with the correct physical action while keeping consent, accessibility, help, and recovery visible.
02 / Architecture
Design the service
before the screens.
The work moved from persona and emotional journey to information architecture, accessibility requirements, wireframes, and polished interface states.
The six-stage journey covers approach; welcome, language, and accessibility; ID input and consent; guided face capture with live feedback; verification; then completion and exit. Help and recovery remain available throughout.
03 / Accessibility by default
Access is part of
the architecture.
Accessibility was specified as a system requirement rather than a final compliance pass. Visual, physical, audible, and tactile support were considered together for a public standing kiosk.
44×44 px touch targets
Controls are sized for confident input and positioned within reach for standing users interacting with fixed hardware.
Voice and audio cues
Built-in spoken guidance and feedback help users understand each step without relying only on visual instructions.
Braille and haptic support
The concept includes braille numpad integration and haptic feedback for input and confirmation.
04 / Prototype foundation
Hardware UX is
service choreography.
The MVP turns the architecture into welcome, language, ID entry, face-scan, live-capture, confirmation, and completion states. Clear overlays and progress feedback make the machine feel supportive rather than opaque.
The design study moved from scenarios and desk research to wireframes and high-fidelity screens, establishing a concept foundation for later iris and fingerprint flows.
The first gesture
