Wearable Gaze Control for Multi-Device Input Conflict Resolution
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 optical symbol recognition.
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 conflicting inputs may occur
Solution Approach 1:
The patent introduces an optical symbol as an intermediary element that mediates between the user's gaze input and the external electronic device. The optical symbol displayed on the external device's screen serves as a visual target that the head-mounted device's sensors track to determine user intent, thereby resolving control ambiguity when multiple devices are paired
Solution Approach 2:
The patent replaces traditional mechanical input devices (buttons, switches, keyboards) with a gaze-based optical control system. The head-mounted device uses cameras and sensors to detect the user's line of sight and interpret gaze direction as control input, substituting physical interaction with optical field-based interaction
2Measurement precision
If gaze input is used to control external devices, then input precision and user interaction quality are improved, but system complexity increases due to sensor processing and optical symbol recognition
Solution Approach 1:
The system implements self-service by having the external electronic device generate and display the optical symbol automatically. The head-mounted device simply needs to detect and track this symbol, rather than requiring complex processing to interpret unstructured gaze data. The external device serves itself by providing the visual target that enables precise control

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.
