Head-Mounted Electronic Device with Magnification Tool - A simplified explanation of the abstract

This abstract first appeared for US patent application 18451787 titled 'Head-Mounted Electronic Device with Magnification Tool

Simplified Explanation

The patent application describes a head-mounted device with displays that can show an image along with a magnifying window displaying a magnified portion of the image. The magnifying window is fixed relative to the user's head, and processors in the device can perform operations to interact with the magnified content.

• Displays in the head-mounted device show an image and a magnifying window simultaneously.
• Processors in the device can identify user input intersecting the magnifying window and perform operations based on that input.
• The device can shift the input point from the magnification plane to another parallel plane for further processing.

• Enhanced viewing experience for detailed work such as graphic design or engineering.

1. 1. 1. Problems Solved

• Difficulty in viewing small details in images or text.
• Limited field of view when using magnifying tools.

1. 1. 1. Benefits

• Improved accessibility for visually impaired users.
• Enhanced user experience for tasks requiring detailed inspection or analysis.

Original Abstract Submitted

A head-mounted device is provided that includes displays configured to display an image and to simultaneously display a magnifying window that presents a magnified portion of the image. The magnifying window lies in a magnification plane that is fixed relative to a user's head. One or more processors in the head-mounted device can be used to perform a first ray cast operation to identify an input point where a detected user input intersects the magnifying window, to obtain a remapped point from the input point, to compute a directional vector based on the remapped point and a reference point associated with the user's head, to obtain a shifted point by shifting the remapped point from the magnification plane to another plane parallel to the magnification plane, and to perform a second ray cast operation using the shifted point and the directional vector.
