Wearable Gaze Control for Conflict-Free External Device Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Controlling additional electronic devices wirelessly paired with head-mounted devices can be difficult due to potential conflicts in user input.
Innovation Solution
A head-mounted device uses gaze input to determine the location of an external electronic device, suppress conflicting inputs, and transmit control signals to the device, allowing precise control through gaze tracking and image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic devices are wirelessly paired with a head-mounted device, then device connectivity and functionality are improved, but user input control becomes difficult and conflicts arise
Solution Approach 1:
The patent introduces an optical symbol as an intermediary element that mediates between the user's gaze input and the control of paired electronic devices. The optical symbol displayed on each device's screen serves as a visual target that the user gazes at to select which device should receive control input, thereby resolving the conflict of which device to control when multiple devices are paired.
Solution Approach 2:
The patent replaces traditional mechanical input devices (buttons, switches, physical controls) with a gaze-based optical control system. By using the user's natural gaze direction as input and displaying optical symbols on device screens, the system substitutes physical interaction with optical-field interaction, enabling more intuitive and conflict-free control of multiple wireless devices.
2Measurement precision
If gaze input is used to control external devices, then control precision is improved, but system complexity increases
Solution Approach 1:
The head-mounted device automatically performs gaze tracking and optical symbol display without requiring additional external equipment. The system uses its own sensors to detect gaze direction and its own display to show optical symbols, making the control system self-contained and not significantly increasing overall system complexity despite the enhanced precision capabilities.

AI summary
A head-mounted device may be used to control one or more external electronic devices. Gaze input and camera images may be used to determine a point of gaze relative to a display for an external electronic device. The external electronic device may receive information regarding the user's gaze input from the head-mounted device and may highlight one out of multiple user interface elements that is targeted by the gaze input. The head-mounted device may receive input such as keystroke information from an accessory device and relay the input to an external electronic device that is being viewed. The head-mounted device may receive a display configuration request, determine layout information for displays in the physical environment of the head-mounted device, and transmit the layout information to an external device associated with the displays.
