Underwater Touchscreen False Touch Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touchscreen displays on image capture devices register false touches when submerged in water, leading to unwanted operations due to water interference, which existing technologies fail to adequately address.
Innovation Solution
The image capture device includes a processor that analyzes visual content to determine if it is underwater, and based on this analysis, automatically adjusts the touchscreen display's operation to prevent false inputs, such as deactivating the display or modifying sensitivity, to prevent unwanted operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the touchscreen display remains active underwater, then user interaction is maintained, but false touches and unwanted operations occur due to water interference
Solution Approach 1:
The touchscreen display dynamically changes its operational state based on environmental conditions. The system transitions between active and inactive states automatically detected through visual content analysis, allowing the touchscreen to adapt its sensitivity and responsiveness to prevent false touches while maintaining user interaction capability when appropriate
Solution Approach 2:
The system continuously monitors visual content to detect water presence and uses this feedback to adjust touchscreen operation. The processor analyzes visual information from the environment and provides real-time feedback to modify touchscreen sensitivity, creating a closed-loop control system that prevents false touches while maintaining usability
2Reliability
If the touchscreen display is deactivated underwater, then false touches are prevented, but user input capability is lost
Solution Approach 1:
The system performs preliminary detection of water presence through visual content analysis before false touches can occur. By detecting environmental conditions in advance and proactively adjusting touchscreen operation, the system prevents false touches rather than merely responding to them, maintaining reliability while preserving user input capability when conditions permit
3Measurement precision
If visual content analysis is performed continuously to detect water presence, then accurate underwater detection is achieved, but processing time and energy consumption increase
Solution Approach 1:
The system performs visual content analysis at selective intervals rather than continuously, analyzing only the necessary portions of visual data to determine water presence. This partial action approach achieves sufficient detection accuracy without the excessive processing time and energy consumption of continuous analysis, optimizing the balance between measurement precision and time loss

AI summary
An image capture device may include a touchscreen display, which may be used to receive user input. The image capture device may determine whether it is under water based on analysis of visual content captured by the image capture device. Responsive to determination that it is under water, the image capture device may change operation with respect to the touchscreen display.
