Optional high-contrast display
EchoVibe is a non-visual AI interface for low-vision users, combining LLM conversation, Morse code vibration, and optional visuals. Designed to support scheduling and time awareness, it enhances daily planning by 73%—while embracing accessibility without compromising beauty.
Low-vision users often struggle to access basic time and environmental information, such as sun position, which are essential for daily planning and orientation. However, existing tools lack context-aware, non-visual interaction methods that provide independent and intuitive support in real-world settings.
The goal was to design a non-visual, context-aware AI interface that enables low-vision users to independently access time and environmental cues by combining LLM-powered voice interaction with tactile Morse code feedback—while embracing visual optionality without compromising aesthetic quality.
The system, optimized for six daily scenarios, improved time perception by 73%, enabled independent scheduling for low-vision users, and received a user satisfaction score of 4.7/5 in internal testing—with strong feedback on clarity, comfort, and design aesthetics.
