Wearable Voice Recognition Module for Multi-Device Wireless Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal mobile electronic devices face challenges in voice command recognition due to size, cost, and distortion issues when worn on the body, as they require individual voice recognition units and microphones, leading to impracticality and user frustration.
Innovation Solution
A system featuring a wearable command module with a microphone and voice recognition unit that generates command data for multiple devices via a wireless protocol, eliminating the need for individual voice recognition units and allowing clear voice command reception from a centralized position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If each personal mobile electronic device includes its own microphone and voice recognition unit, then voice command recognition capability is provided for each device, but device size increases and becomes impractical for carrying multiple devices
Solution Approach 1:
A single wearable command module with voice recognition capability serves multiple personal mobile electronic devices simultaneously. The command module includes a microphone and voice recognition unit that can identify and execute voice commands for different devices (cellular telephone, PDA, handheld computer, music player, digital watch), allowing one device to perform the function of multiple voice recognition units.
Solution Approach 2:
The patent combines the microphone and voice recognition unit into a separate wearable command module that is distinct from the personal mobile electronic devices. This modular approach allows the voice recognition functionality to be shared across multiple devices without increasing the size of each individual device.
2Ease of operation
If each personal mobile electronic device includes its own microphone and voice recognition unit, then voice command recognition capability is provided for each device, but manufacturing cost increases substantially
Solution Approach 1:
The wearable command module serves as a universal voice recognition device for multiple personal mobile electronic devices. By manufacturing one command module instead of multiple voice recognition units distributed across different devices, manufacturing costs are reduced while maintaining full voice command recognition capability.
Solution Approach 2:
The patent consolidates the voice recognition functionality into a single wearable command module, reducing the total number of voice recognition units that need to be manufactured. This merging approach eliminates redundant manufacturing of microphones and voice recognition units across multiple devices.
3Ease of operation
If the personal mobile electronic device is positioned away from the user's mouth (e.g., on belt or in pocket), then the device is more mobile and convenient to carry, but voice command reception becomes muffled or distorted
Solution Approach 1:
The patent divides the voice recognition system into two separate components: a wearable command module with microphone that can be positioned near the user's mouth for clear voice capture, and the personal mobile electronic devices that can be carried conveniently anywhere on the body. The command module wirelessly transmits recognized commands to the devices, allowing the microphone to be optimally positioned for voice reception while devices remain mobile.
Solution Approach 2:
The wearable command module acts as an intermediary between the user's voice commands and the personal mobile electronic devices. It captures voice commands near the mouth, processes them through voice recognition, and transmits the interpreted commands wirelessly to the devices, eliminating the need for devices to be positioned near the mouth.
Data Source
AI summary
Described are a method and system for controlling the operation of personal mobile electronic devices disposed about a user. Each device is adapted to receive command according to a common wireless protocol. A voice signal is generated in response to a voice command spoken by the user. Command data are generated for one of the devices in response to the voice signal. The command data are transmitted through a wireless link to the respective device to control an operation of the device. There is no need for each device to have independent voice recognition capability. Instead, the burden of voice recognition is managed by the wearable command module that communicates with all the controlled devices through wireless links.
