Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch panel sampling rates in electronic devices lead to high power consumption or poor gesture-following performance, depending on the application scenario, necessitating an adjustment method that balances user and application requirements.
Innovation Solution
An electronic device adjusts the touch panel sampling rate based on user input and application type, considering performance switch control and scenario changes to optimize power consumption and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the touch panel driver always scans the touch input at a relatively high TP sampling rate, then the gesture-following performance is improved, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by making the TP sampling rate adjustable rather than fixed. The system dynamically changes the sampling rate based on the running application's requirements and user preferences, switching between high sampling rates for games (better gesture-following) and low sampling rates for other applications (lower power consumption).
Solution Approach 2:
The patent changes the parameter of TP sampling rate based on different conditions. It identifies the type of running application and adjusts the sampling rate parameter accordingly - using higher sampling rates for applications requiring good gesture-following performance and lower sampling rates for applications where power consumption is more critical.
2Use of energy by moving object
If the touch panel driver always scans the touch input at a relatively low TP sampling rate, then the power consumption is reduced, but the gesture-following performance deteriorates
Solution Approach 1:
The system dynamically adjusts the sampling rate based on the current application context, allowing it to operate at low sampling rates for power saving when appropriate, and switch to high sampling rates when gesture-following performance is needed.
Solution Approach 2:
The sampling rate parameter is changed based on application type identification. The system lowers the sampling rate for applications that don't require high gesture-following performance, thereby reducing power consumption while maintaining acceptable user experience.
3Reliability
If the TP sampling rate is adjusted to meet application requirements, then the gesture-following performance is improved, but the device complexity increases
Solution Approach 1:
The system performs self-service by automatically identifying the running application type and selecting the appropriate sampling rate without requiring manual user intervention. The application type identification and sampling rate selection are handled autonomously by the system based on pre-defined criteria.
Solution Approach 2:
The system uses feedback from application identification to adjust the sampling rate. By monitoring which application is running and using this information to select the appropriate sampling rate, the system creates a feedback loop that optimizes performance based on current usage conditions.

AI summary
Embodiments of this application provide a method for adjusting a TP sampling rate and an electronic device and relate to the field of terminal technologies. A TP sampling rate can be adjusted according to an adjustment requirement of a user for the TP sampling rate and an actual requirement of running a first application for the TP sampling rate, so that the adjusted sampling rate meets the requirements of the user and the first application for the TP sampling rate, to improve satisfaction of the user on gesture-following performance of the electronic device. The method is applicable to an electronic device, where the electronic device includes a TP and a first application is installed on the electronic device. The method may include: starting the first application; obtaining an identifier of the first application; receiving a first operation inputted by a user, where the first operation corresponds to a performance switch control; obtaining a status of the performance switch control in response to the first operation; determining a TP sampling rate as a first sampling rate according to the identifier of the first application in a case that the status of the performance switch control changes; and scanning a touch operation on the TP based on the first sampling rate.
