Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face power waste and resource consumption issues due to constant gesture recognition, as they need to process sensing signals for potential user gestures at all times, leading to inefficient power usage and resource management.
Innovation Solution
An electronic device equipped with sensors and a processor that only activates specific sensor modules upon request from an application, allowing for gesture recognition only when necessary, using the sum of sensed signals over a predetermined period to identify gestures efficiently.

Engineering Contradiction Analysis
1Speed
If the electronic device continuously activates sensors and processes sensing signals for gesture recognition, then gesture recognition responsiveness is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by activating sensor modules only at predetermined intervals or upon receiving a request signal from an application, rather than continuously. The processor periodically checks for gesture recognition requests and activates relevant sensor modules (e.g., accelerometer, gyroscope, optical sensor) only when needed, thereby reducing power consumption while maintaining gesture recognition capability when required.
Solution Approach 2:
The patent applies dynamics by making the sensor module activation state changeable based on system conditions. The processor dynamically adjusts the activation state of sensor modules according to whether gesture recognition requests are received from applications, transitioning between active and inactive states as needed. This dynamic adjustment allows the system to optimize the balance between responsiveness and power consumption.
2Measurement precision
If the electronic device constantly processes sensing signals for gesture recognition, then gesture recognition accuracy is improved, but resource consumption increases
Solution Approach 1:
The patent applies partial action by processing only the necessary portion of sensing signals based on actual gesture recognition requests. Instead of continuously processing all sensor data, the system activates and processes signals from relevant sensor modules only when a gesture recognition request is received, thereby reducing resource consumption while maintaining accuracy when needed.
Solution Approach 2:
The patent implements local quality by selectively activating specific sensor modules based on the type of gesture recognition required. Different sensor modules (accelerometer for linear motion, gyroscope for rotational motion, optical sensor for hand gestures) are activated only when their specific gesture types are needed, optimizing resource allocation while maintaining recognition accuracy for the required gesture modalities.
3Ease of manufacture
If the electronic device uses conventional gesture recognition schemes, then implementation simplicity is improved, but gesture recognition performance deteriorates
Solution Approach 1:
The patent applies universality by creating a unified gesture recognition system that can handle multiple gesture types (hand gestures, body gestures, head gestures) through a single integrated architecture. The system uses a common request signal mechanism and processor-based control to manage different sensor modules, simplifying implementation while improving performance through multi-functional capability.
Solution Approach 2:
The patent implements preliminary action by pre-establishing the request signal mechanism and sensor module activation protocols before actual gesture recognition occurs. The system is configured in advance to automatically activate appropriate sensor modules when requests are received, eliminating the need for complex real-time decision-making and simplifying implementation while maintaining high performance.
