Dynamic Cursor Display With Center-Point Shifting for External Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tablet computers cannot effectively utilize finger touch operations when connected to external devices like mice or touchpads, limiting their functionality.
Innovation Solution
The electronic device dynamically changes the appearance of the cursor during movement by shifting its center point and adjusting its flatness, creating a dragging effect to enhance user interaction with external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tablet computer uses finger touch operation mode, then it can provide intuitive control for touch operations, but it cannot effectively support external devices like mice or touchpads
Solution Approach 1:
The cursor appearance is dynamically adjusted during movement based on acceleration and velocity parameters. The system calculates real-time movement dynamics and modifies cursor properties (flatness, size, shape) accordingly, enabling the same cursor to adapt to different movement states and external device interactions
2Ease of manufacture
If the cursor appearance remains static during movement, then it is simple to implement, but it cannot provide visual feedback for dragging operations
Solution Approach 1:
The system changes multiple cursor parameters simultaneously during movement: flatness increases with acceleration to simulate dragging, size adjusts based on velocity, and shape transforms to reflect movement state. These parameter changes provide continuous visual feedback without requiring separate cursor designs for different operations
3Device complexity
If the cursor center point remains at the geometric center, then it is easy to render, but it cannot create the dragging effect visual users expect
Solution Approach 1:
The cursor center point is deliberately offset from the geometric center during accelerated movement. This asymmetric positioning creates the visual illusion of dragging by showing the trail behind the actual cursor position, matching user expectations from traditional mouse operations

AI summary
A cursor display method and an electronic device. The method includes an electronic device moving a cursor on a display interface in response to a received user operation. In addition, in a cursor movement process, a cursor center point gradually shifts from a center position of the cursor along an opposite direction of a moving direction of the cursor with movement of the cursor, to achieve a dynamic cursor dragging effect on the display interface.
