Mobile Terminal Touch Area Segmentation for Wearable Cursor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interaction methods between smartphones and AR/VR glasses, such as using the phone as a pointer or touch pad, suffer from drift errors, user fatigue, low accuracy, and increased operation complexity, especially when typing or performing extensive movements on virtual interfaces.
Innovation Solution
The method involves displaying touch areas on a mobile terminal's screen to control the moving speed of a cursor on a wearable device's interface, allowing users to move the cursor quickly or slowly based on touch operations, reducing the need for frequent calibration and simplifying interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the phone is used as a pointer or touch pad to control AR/VR glasses, then the functionality and operability are improved, but drift errors occur and accuracy decreases
Solution Approach 1:
The touch screen is divided into multiple touch areas, each corresponding to different cursor movement speeds. This segmentation allows the system to provide different levels of precision for different operational needs, resolving the contradiction between versatility and accuracy by offering specialized zones for different tasks.
Solution Approach 2:
Different regions of the touch screen are assigned different functions and properties. Specifically, certain touch areas are configured to control cursor movement at different speeds, creating local quality variations that optimize both overall functionality and specific accuracy requirements for different operations.
2Ease of operation
If the phone is used as a pointer for extended periods, then operability is maintained, but user fatigue increases
Solution Approach 1:
The system dynamically adjusts cursor movement speed based on the touch area detected. This dynamic control allows the cursor to move faster across large distances, reducing the time and effort required for extended operations, thereby maintaining ease of operation while reducing user fatigue during prolonged use.
3Measurement precision
If the cursor moves slowly for precise control, then accuracy is improved, but operation complexity and time increase
Solution Approach 1:
The system provides multiple touch areas with different cursor speeds, allowing users to apply partial action (slower speed) only when precision is needed, while using faster speeds for routine movements. This reduces overall operation complexity by eliminating the need to manually adjust settings or use complex gestures to change speed.
Solution Approach 2:
The cursor movement speed parameter is changed based on the detected touch area. By automatically adjusting this parameter according to the user's input location, the system simplifies operation complexity while maintaining the ability to achieve high precision when required, without manual intervention.
4Productivity
If the cursor moves quickly across the interface, then productivity is improved, but accuracy decreases
Solution Approach 1:
The touch screen is segmented into multiple areas that correspond to different cursor speeds. This allows the system to automatically provide high-speed cursor movement for general navigation (improving productivity) while offering slower, more precise control in specific touch areas when positioning accuracy is needed, thus resolving the contradiction between speed and precision.
Data Source
AI summary
An information interaction method is applied to a mobile terminal and includes displaying at least one touch area configured to control a moving speed of a cursor on a touch screen of the mobile terminal, in response to detecting an operation on the mobile terminal; and sending a first control instruction to a wearable device in response to detecting a touch operation in any touch area, the first control instruction being configured to instruct the cursor on a display interface of the wearable device to move according to the moving speed indicated by the touch area.
