AI Technical Summary

Technical Problem

Consumers and creators of smart glasses and other wearable computing devices face challenges in identifying a suitable user interface that is discrete, highly-accurate, and does not rely on line-of-sight, infrared, or video cameras, as motion-based controls are difficult to calibrate and traditional interaction methods are cumbersome.

Method used

A wearable device interaction system that includes a ring-based interface with capacitive and pressure sensors to detect movements and interactions, utilizing quadrature sensing to determine the location and magnitude of compressions, enabling precise control without the need for visual or camera-based systems.

Benefits of technology

Provides a simplified and accurate method for interacting with wearable devices, allowing users to perform actions with high precision and discretion, enhancing user experience and interaction efficiency.

Abstract

A wearable ring for a human user, the device includes an interior loop of the ring, an exterior loop of the ring surrounding the interior loop, an interior space between the interior loop and the exterior loop. Disposed within the ring are a plurality of sensors arranged within the interior space at predetermined intervals along a circumference of the ring, such that when the exterior loop is moved closer to the interior loop at a particular point along the circumference of the ring through interaction with the exterior loop, a change detected by at least one of the sensors identifies an area near the particular point as an interaction with the ring.
