Touch Screen Display Area Adjustment for Accidental Contact Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accidental hand contact with touch screens on portable electronic devices often leads to erroneous responses due to the lack of effective methods to differentiate between intentional and unintentional interactions, resulting in increased workload and error rates for the device.
Innovation Solution
A display method and electronic device that senses operations on a touch screen, determines a contact area, and adjusts the display area based on this information to prevent accidental interactions by scaling down or excluding the contact area, thereby reducing error responses and enhancing user experience.

Engineering Contradiction Analysis
1Area of stationary object
If the touch screen is made larger to improve performance, then the display area and interaction capability are enhanced, but the likelihood of accidental hand contact increases
Solution Approach 1:
The display screen is divided into multiple display areas, where the first display area corresponds to the contact area and the second display area corresponds to the non-contact area. This segmentation allows the system to selectively stop display in the contact area while maintaining display in the non-contact area, thereby reducing erroneous responses from accidental touches while preserving the large screen real estate for intentional interactions.
2Reliability
If the entire display area is stopped to prevent accidental touches, then error responses are reduced, but the user loses access to the displayed content
Solution Approach 1:
Instead of applying a uniform stop-display action across the entire screen, the system applies the stop-display action locally only to the first display area that corresponds to the contact area. The second display area continues to display content normally, ensuring that users can still access and interact with the displayed content through the non-contact areas while preventing erroneous responses from accidental touches.
3Reliability
If the display area is adjusted based on contact area information, then accidental touches are prevented, but the display layout complexity increases
Solution Approach 1:
The system extracts the contact area information from the touch operations and uses this extracted information to determine the first display area. By separating the contact area detection and display area adjustment logic, the system can prevent accidental touches through targeted display stopping in the first display area while maintaining normal display in the second display area, without requiring complete redesign of the display system.

AI summary
A display method and an electronic device are provided. The display method includes sensing a first operation performed on a display screen of an electronic device. The display method also includes determining a first contact area of the display screen corresponding to the first operation based on information of the first operation. Further, the display method includes adjusting a first display area of the display screen to a second display area based on information of the first contact area.
