AI Technical Summary

Technical Problem

Existing user-worn devices using magnetometers for location determination and tracking suffer from inaccurate and unreliable visual reproduction of the device's location on an output device due to the specific arrangement of magnetometers and output devices.

Method used

A user-worn device with an elongated body featuring immovable and movable magnetically responsive components, including at least one permanent magnet, which modifies its magnetic signature through relative movement, allowing identification by multiple magnetometers.

Benefits of technology

Enhances detection accuracy of user-worn devices by modifying their magnetic signature, enabling precise identification and differentiation between various types and characteristics without requiring electronic components within the device.

Abstract

A user-worn device (100) for use with a digital device incorporating multiple magnetometers (300), A long, slender body (101) defines the longitudinal axis (L) of the user-worn device (100), A first magnetically responsive component (104) is immovably positioned at or near the proximal end (102) of the elongated main body (101), The device comprises a first magnetically responsive component (104) and a second magnetically responsive component (105) positioned between the first magnetically responsive component (104) and the distal end (103) of the elongated body (101) along at least a portion of the longitudinal axis (L) of the user-worn device (100), A user-worn device (100) in which a second magnetically responsive component (105) is configured to translate relative to a first magnetically responsive component (104) and / or rotate relative to the longitudinal axis (L) of the user-worn device (100).
