Voice-Controlled Mobile Device Identification by Messageless Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Similar-looking devices in organizations often lack distinguishable features, making it difficult to select the appropriate device for a specific assignment, especially when individuals are unaware of the subtle differences in appearance.
Innovation Solution
A spoken command system that utilizes speech recognition to convert audio signals into formatted commands, enabling specific operational actions on subsets of mobile devices based on device-identifying criteria, and provides messageless indications to differentiate these devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If devices are made to look similar for uniformity, then ease of storage and handling is improved, but device distinguishability deteriorates
Solution Approach 1:
The patent applies color changes by using different colored LED indicators on devices to provide visual differentiation. The system can illuminate specific devices with distinct colors or patterns, allowing users to easily identify and select the desired device from a group of otherwise identical-looking devices, thereby resolving the contradiction between uniform appearance and distinguishability.
2Manufacturing precision
If device features are made subtle for uniformity, then manufacturing precision is improved, but device identification becomes more difficult
Solution Approach 1:
The patent introduces an intermediary identification mechanism (LED indicators and visual cues) that does not require modifying the device structure itself. This intermediary system provides clear identification signals while maintaining the subtle, uniform appearance of the devices, thus preserving manufacturing precision while improving device identification.
3Ease of operation
If speech recognition is used to control devices, then ease of operation is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by implementing a centralized server that handles speech recognition and command processing for multiple devices. This multi-functional system can identify, differentiate, and control various devices through a single interface, improving ease of operation while managing system complexity through consolidation rather than requiring complex individual processing in each device.

AI summary
A spoken command system and method therefor is disclosed. The method includes processing a formatted command signal at a server which communicates with at least one mobile device (that is a subset of a plurality of mobile devices) to initiate therein the at least one operational action. In response to a successful initiation or a successful completion of the at least one operational action, the at least one mobile device is caused to emit a predefined messageless indication to permit a human to distinguish the subset of the mobile devices from the remaining devices of the plurality of mobile devices.
