Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for interacting with Augmented Reality (AR) glasses, such as voice commands and button presses, are inconvenient, especially in silent environments, and suffer from accuracy issues due to noise and language limitations, and are uncomfortable for users.
Innovation Solution
An infrared contactless gesture system that uses proximity sensors on AR glasses to detect hand gestures, generating signals corresponding to commands and executing them, allowing for silent and intuitive control of AR applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice commands are used to control AR glasses, then hands-free operation is achieved, but control accuracy deteriorates due to ambient noise and voice quality issues
Solution Approach 1:
The patent replaces voice-based acoustic control with infrared optical sensing and gesture recognition. The infrared proximity sensor detects hand movements and gestures through optical fields rather than acoustic fields, eliminating the harmful effects of ambient noise on control accuracy while maintaining hands-free operation convenience.
2Measurement precision
If button presses on AR glasses are used for control, then precise input is achieved, but user comfort deteriorates due to the small size and location of buttons
Solution Approach 1:
The patent introduces an intermediary gesture recognition system that translates physical hand gestures into control commands. Instead of directly pressing small buttons on the glasses, users perform gestures in the air that are detected by the infrared sensor, serving as an intermediary between natural hand movements and device control, thereby improving comfort while maintaining input precision.
3Ease of operation
If conventional control methods are used in silent environments, then operation is possible, but control accuracy deteriorates due to silence requirements
Solution Approach 1:
The patent substitutes acoustic-based voice commands with optical-based infrared gesture recognition. This replacement allows control operations to proceed accurately in silent environments where voice commands would fail, as the infrared sensor detects gestures through light rather than sound, eliminating the dependency on acoustic signals.
4Adaptability or versatility
If voice recognition is implemented to support multiple languages, then adaptability improves, but system complexity increases due to configuration requirements
Solution Approach 1:
The patent extracts and eliminates the complex voice recognition configuration system entirely by replacing it with gesture-based control. This removal of the voice recognition subsystem eliminates the need for language support configuration, multi-language processing, and associated complexity, while maintaining adaptability through universal gesture recognition that works across different users and contexts.
