Portable Terminal Gesture Activation for Voice Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals, such as smartwatches and wrist phones, face inconvenience in activating voice recognition functions while worn on the wrist or ankle, requiring manual input and leading to unnecessary power consumption due to the need for continuous monitoring.
Innovation Solution
A method that detects specific gestures to activate the touch screen and voice recognition module, allowing voice control without manual input, and determines whether to execute functions based on personal information presence, optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the voice recognition module is continuously monitored to enable immediate voice recognition, then the responsiveness to voice input is improved, but the power consumption increases
Solution Approach 1:
The system performs preliminary action by detecting specific gestures (such as wrist rotation or double-tap gestures) that trigger the voice recognition module in advance. Instead of continuous monitoring, the gesture detection mechanism prepares the system for voice recognition by activating the module only when the predetermined gesture is detected, thereby reducing unnecessary power consumption while maintaining responsiveness when needed
Solution Approach 2:
The voice recognition module operates in periodic intervals rather than continuously. The system alternates between active voice recognition mode (triggered by gesture detection) and inactive state, creating a periodic operation pattern that reduces overall power consumption while ensuring the module is available when activated by user gesture
2Ease of operation
If the touch screen and voice recognition module are activated by gesture detection, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The gesture detection system serves multiple functions: it detects wrist rotations to activate the touch screen, detects double-tap gestures to activate voice recognition, and can distinguish between different gesture types. This multi-functionality reduces the need for separate dedicated buttons or switches, simplifying the overall device structure while enhancing ease of operation
Solution Approach 2:
The gesture detection mechanism acts as an intermediary between the user and the voice recognition module. Instead of directly pressing buttons or speaking immediately, the user performs a gesture that mediates the activation of the voice recognition system, providing a natural and convenient interface that reduces operational complexity
3Device complexity
If manual input is required to activate the touch screen and voice recognition function, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The system provides self-service by automatically detecting gestures and activating the appropriate modules without requiring manual button presses or complex menu navigation. The gesture detection system autonomously determines when the touch screen or voice recognition module should be activated based on predefined gesture patterns, eliminating the need for manual activation input

AI summary
The present disclosure relates to a portable terminal, and more particularly, to a portable terminal and a method of detecting a gesture and controlling a function. A method of controlling a function of a portable terminal includes: detecting a gesture; activating a voice recognition module in response to the detected gesture; and analyzing a voice input into the activated voice recognition module, and executing a function corresponding to the input voice.
