PrecisionOS

PrecisionOS is a surgical education platform that needed a mobile companion app with complex technical requirements: live surgery streaming with multiple simultaneous camera angles, a searchable video content catalog organized by procedure and specialty, user profile management with customizable avatars for the educational community, and a contact invitation system for private streams and study groups.

The design and architecture needed to work in high-stakes surgical environments where surgeons might be referencing content during actual procedures. This meant every interaction had to be achievable with minimal taps, information density had to be high without feeling cluttered, and the multi-camera selection interface needed to be intuitive enough to switch views without looking away from the surgical field. Full landscape mode support was mandatory for optimal video viewing during procedures.

We delivered a complete design and architecture package: brand book establishing the visual identity, a comprehensive design system with component library, low-fidelity wireframes mapping all user flows, high-fidelity mockups for every screen, and an interactive prototype for stakeholder validation.

The streaming architecture was planned around Mux for video infrastructure — it handles adaptive bitrate streaming (HLS) that adjusts quality based on network conditions, critical for hospital WiFi environments that can be unpredictable. WebRTC integration enables the live streaming component with sub-second latency for real-time surgical feeds. The multi-camera feature allows viewers to select between different surgical views (overhead, close-up, instrument, wide-angle) with smooth transitions.

The design system includes a comprehensive logo suite, color palette calibrated for extended screen viewing (reduced blue light considerations for surgeons watching during long procedures), typography scale optimized for readability on mobile displays at arm's length, input field patterns for search and filtering, iconography system, and reusable components.

The app covers account creation with institutional verification, a home screen with integrated live stream previews, the multi-camera selection interface for surgical views, a browsable video content library with specialty and procedure filtering, profile settings with avatar customization for the educational community, stream configuration settings, and a contact invitation system supporting both manual entry and contact list import for private educational sessions.

Full landscape mode was designed for every video-related screen, with controls that auto-hide during playback and reappear on tap, maximizing the viewing area. AWS with CloudFront CDN was selected for the infrastructure to ensure low-latency video delivery across North America.
