Designing for High-Stakes Mobility - In-Car Video System

DESIGN BRIEF

Public safety officers rely on in-vehicle camera systems to capture and review evidence while in motion. The main goal is to create and maintain an experience that delivers clarity, speed, and trust to streamline field operations, improve officer safety, and accelerate evidence workflows — even in physically constrained, high-pressure environments.

CONSTRAINTS
  • Ensure intuitive HCI to support mission-critical workflows in high-stress situations.
  • Maintain user trust through clear visual and audio cues while reducing unnecessary distractions under variable lighting and motion conditions.
  • Support cohesive and seamless integrations between in-car system, body cameras, evidence management software, and mobile apps.

PROCESS
  • Field Research — participated in ride-alongs, contextual interviews, usability/concept testing with admins and officers.
  • User Journey — mapped complex, end-to-end workflows and key touchpoints for various user personas across multiple devices.
  • Prototyping — Low-fi to hi-fi iterations tested in simulated driving conditions.
  • Iterative Refinement — addressed user pain points gathered from research insights and prototyping/testing.

IMPACT
  • Increased user confidence ratings in post-deployment surveys.
  • Design framework is scalable for other high-stakes environments (e.g., ambulance diagnostics, dispatching fire fighters).
