Overview
EchoVibe : Time, Schedule & Emergency Assistant for Low Vision
This wearable ring enables non-visual interaction for low-vision users through LLM, haptics, ring rotation, and gesture input. While specific features cannot be disclosed here due to an active provisional patent and an ongoing utility patent process, the design prioritizes intuitive access, temporal awareness, and seamless daily integration.

Optional high-contrast display
This project optionally includes a visual display, designed with high-saturation colors to ensure visibility for a wide range of users with low vision—while preserving aesthetic beauty. The display also communicates with the LLM-based AI and can interact with the wearable ring.
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.
