Touch Screen Control via Curvilinear Sliding Tracks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch screen devices face difficulties in determining the specific display orientation when a dedicated operation area is designated, leading to inconvenient user experiences, especially for large-size touch screens used by multiple users simultaneously.
Innovation Solution
A method and apparatus that detect operation inputs on a touch screen to form sliding tracks, judge if they meet predetermined conditions involving curvilinear tracks with specific contact points, and determine independent operation areas and display orientations based on these tracks, allowing for improved user interaction and security by recording operator characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dedicated operation area is designated on a touch screen, then user operation convenience is improved, but the device cannot determine the specific display orientation
Solution Approach 1:
The system performs preliminary action by detecting the sliding track before the operation is executed, and uses this track information to pre-determine both the dedicated operation area and the display orientation. This allows the device to prepare the correct display orientation in advance based on the user's sliding gesture, resolving the contradiction between enabling dedicated area operation and determining display orientation.
2Adaptability or versatility
If multiple users operate simultaneously on a large touch screen, then user accessibility is improved, but accidental access by unauthorized users increases
Solution Approach 1:
The system applies local quality by creating distinct dedicated operation areas for different users on the same touch screen. Each area has its own operational characteristics and is associated with specific user information. This allows multiple users to access the device simultaneously with their own personalized areas, while preventing unauthorized access to other users' areas, thus resolving the contradiction between accessibility and security.
3Stability of the object's composition
If the display orientation remains in the original orientation, then display consistency is maintained, but user convenience is reduced
Solution Approach 1:
The system implements dynamics by making the display orientation adjustable and adaptable based on the detected sliding track. Instead of maintaining a fixed original orientation, the display orientation dynamically changes according to the user's gesture and the determined dedicated area. This allows the display to adapt to different user positions and preferences, resolving the contradiction between display consistency and user convenience.

AI summary
The present invention discloses a method and apparatus for controlling an electric device. The electric device has a touch screen. The method comprises: detecting whether there is an operation input on the touch screen so as to generate a piece of detection information; when the detection information indicates that there is an operation input on the touch screen, forming a sliding track on the touch screen in response to the operation; judging whether the sliding track meets a predetermined condition so as to generate judgment information, wherein the predetermined condition is that the sliding track is a curvilinear track and comprises a first contact point and a second contact point, the first contact point and the second contact point being contact points which coincide or not coincide with each other; determining an independent operation area on the touch screen based on the sliding track, and determining a display orientation of a displayed object within the independent operation area based on the sliding track when the judgment information indicates that the sliding track meets the predetermined condition.
