Touch Control Speed Adjustment via Pressing Force Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in accurately and quickly executing desired functions due to high key repeat speeds, which can result in unintended positions or values being missed during touch operations, especially when key repeat intervals are short.
Innovation Solution
An electronic apparatus is designed with a touch detector and a pressing detector that adjusts the speed or execution frequency of functions based on the pressing operation, maintaining a reduced speed for a predetermined period even after the pressing operation changes, ensuring accurate and quick execution of intended functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the key repeat interval is shortened to increase execution speed, then the productivity is improved, but the manufacturing precision deteriorates because the intended position or value may be erroneously passed over
Solution Approach 1:
The key repeat interval is dynamically adjusted based on the detected pressing force. When pressing force exceeds the threshold, the interval is extended (execution speed decreased). When pressing force is below the threshold, the interval is shortened (execution speed increased). This dynamic adjustment resolves the contradiction by adapting the execution speed to the user's intent indicated by pressing force.
Solution Approach 2:
The system changes the parameter of key repeat interval based on the pressing force detected by the pressing detector. By using pressing force as a control parameter, the system can switch between different execution speeds (short interval for light touch, long interval for heavy press) to balance productivity and precision according to user intent.
2Manufacturing precision
If the key repeat interval is extended to decrease execution speed, then the manufacturing precision is improved, but the productivity deteriorates because a result aimed at takes longer to approach
Solution Approach 1:
The key repeat interval is dynamically adjusted based on the detected pressing force. When pressing force is below the threshold, the interval is shortened (execution speed increased) to quickly approach the intended result. When pressing force exceeds the threshold, the interval is extended (execution speed decreased) to ensure precision. This dynamic adjustment resolves the contradiction by adapting execution speed to user intent.
Solution Approach 2:
The system changes the parameter of key repeat interval based on the pressing force detected by the pressing detector. By using pressing force as a control parameter, the system can switch between different execution speeds (short interval for light touch, long interval for heavy press) to balance productivity and precision according to user intent.

AI summary
In an electronic apparatus, a control unit performs control to continuously perform a predetermined function according to continuation of a touch operation on an operation surface, to decrease a speed or execution frequency of the predetermined function according to a pressing operation being detected with the touch operation on the operation surface kept continued, and not to increase the speed or execution frequency of the predetermined function for a predetermined period even when a state of the pressing operation being detected is changed to a state of the pressing operation not being detected with the touch operation on the operation surface kept continued.
