User Configurable Speech Commands for Wireless Headsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices face limitations in providing a hands-free, high-quality, portable, and large-format display solution due to their physical size and user interface dependency on keyboards or touch screens, which restricts mobility and visual experience.
Innovation Solution
A wireless computing headset with high-resolution micro-displays and integrated optics, coupled with a speech recognition engine, allows users to control the device with voice commands and gestures, enabling hands-free operation and enhanced mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If mobile computing devices use traditional display screens and keyboard/touch interfaces, then they can provide basic computing functionality, but they cannot provide a large-format, high-resolution display experience while maintaining mobility
Solution Approach 1:
The patent transitions the display from a two-dimensional screen confined to the device body to a three-dimensional experience by projecting images into the user's field of view using head-mounted micro-displays. This allows large-format display content to be presented without increasing the physical size of the mobile device itself.
Solution Approach 2:
The patent embeds small high-resolution micro-displays within the compact form factor of mobile devices and wearsable head-mounted units. These nested micro-displays provide large-format display capabilities while maintaining the small physical footprint of the device through optical magnification and immersive projection.
2Ease of operation
If mobile computing devices use hands-dependent interfaces such as keyboards and touch screens, then users can input data and make selections, but users cannot operate the device hands-free and mobility is restricted
Solution Approach 1:
The patent replaces mechanical and tactile input methods (keyboards, touch screens) with acoustic field-based speech recognition. Users communicate commands through voice uttered into a microphone, eliminating the need for physical hand interactions with the device interface while maintaining operational capability.
Solution Approach 2:
The patent introduces a speech recognition engine as an intermediary between the user and the device. This intermediary translates acoustic speech signals into device commands, enabling hands-free operation without requiring direct physical or visual interaction with the device interface.
3Adaptability or versatility
If the device provides preset speech commands, then voice control is enabled, but the device cannot adapt to user-specific speech patterns and preferences
Solution Approach 1:
The patent makes the speech recognition system dynamic and adaptable by allowing users to configure and customize speech commands according to their preferences. The system can be adjusted to recognize user-specific speech patterns, alternative phrasings, and personalized commands, transforming from a static preset system to a flexible, user-tailored interface.

AI summary
A speech recognition method and system enables user-configurable speech commands. For a given speech command, the speech recognition engine provides a mechanism for the end-user to select speech command terms to use in substitution for the given speech command. The speech recognition engine, or module thereof, forms a replacement command for the given speech command from the user-selected speech command terms. The speech recognition engine thereafter is synonymously responsive to user utterance of the replacement command as though the user issued/voiced the associated counterpart given speech command.
