US 2025/0060426 A1 · Electronic Devices With Optical Assembly Position Sensors

Abstract

A head-mounted device may include optical assemblies for presenting images to a user. Each optical assembly may have a support configured to support a display, a lens through which an image from the display is presented to an eye box for viewing, and a sensor. Each support may have an opening configured to receive a guide rod along which the support slides to adjust where the optical assembly is positioned along that guide rod. Each guide rod may include a position index such as a strip-shaped index formed from alternating magnetic poles or alternating light and dark regions. A magnetic sensor or optical sensor may monitor the position index as the support slides along the guide rod to determine the position of the support and optical assembly along the guide rod.

Dependent claims

A head-mounted device, comprising:

a head-mounted housing;
guide rods coupled to the head-mounted housing, each guide rod including a respective position index;
and
optical assemblies, wherein each optical assembly includes:
a lens;
a display that is configured to provide an image to an eye box through the lens;
