Collaboration Window Pointer Shape Switching by Operation Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to dynamically transform the mouse pointer shape in collaboration windows based on the area of operation, leading to inconvenient user interactions and suboptimal user experience when selecting text or adjusting images.
Innovation Solution
A display control method that projects a screen from a first device to a second device, dynamically configuring the mouse pointer shape in the collaboration window based on the area of operation by synchronizing pointer icon libraries and simulating mouse pointer inputs to match target sub-areas, allowing the second device to display the pointer in appropriate shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed mouse pointer shape is used in collaboration window, then device complexity is reduced, but ease of operation deteriorates due to inability to perform text selection and image adjustment
Solution Approach 1:
The mouse pointer shape is changed from static to dynamic, allowing it to automatically transform between different shapes (text selection pointer, image adjustment pointer, default pointer) based on the detected area where the pointer is located. This dynamic adaptation enables the pointer to provide context-appropriate functions without requiring manual user configuration, thereby improving ease of operation while maintaining automated complexity management.
Solution Approach 2:
The system implements feedback by continuously monitoring the position of the mouse pointer and automatically adjusting the pointer shape based on the detected area. When the pointer enters a text area, the system feedbacks by changing it to a text selection pointer; when in an image area, it feedbacks by changing to an image adjustment pointer. This closed-loop feedback mechanism enables adaptive behavior that improves operational convenience.
2Ease of operation
If dynamic pointer shape transformation is implemented, then ease of operation is improved, but device complexity increases due to pointer shape management
Solution Approach 1:
The system employs self-service by enabling the collaboration window to automatically detect the area where the mouse pointer is located and autonomously select the appropriate pointer shape without requiring user intervention. The window itself serves the function of managing pointer shapes by detecting pointer position and triggering appropriate shape changes, thereby reducing the need for complex external pointer management mechanisms.
Solution Approach 2:
The collaboration window is designed with multi-functionality, serving both as the display area for content and as the controller for pointer shape management. The window integrates multiple functions: displaying content, detecting pointer position, determining pointer shape, and triggering shape changes. This universal design consolidates what could be separate complex components into a single integrated system.
3Adaptability or versatility
If area-based pointer detection is implemented, then adaptability is improved, but measurement precision requirements increase for area detection
Solution Approach 1:
The collaboration window is segmented into multiple distinct areas (text area, image area, other areas) with clear boundaries. Each area is independently defined and detected, allowing the system to determine pointer location by identifying which segmented region the pointer currently occupies. This segmentation approach simplifies the measurement task by breaking down the continuous space into discrete, easily identifiable zones.
Solution Approach 2:
Different areas within the collaboration window are assigned different local qualities or characteristics that enable easy detection. The text area, image area, and other areas have distinct properties that allow the system to identify which area the pointer is in based on simple position checking rather than complex measurement. Each local area has its own detection criteria, making the overall detection process more manageable.

AI summary
A display control method and apparatus for a pointer in a window, a device, and a storage medium. A first device projects a screen onto a second device to generate a collaboration window. When a user performs an operation through a mouse of the second device, in response to a mouse pointer of the second device being in a first area of the collaboration window, the mouse pointer is displayed in a first shape, and in response to the mouse pointer of the second device being in a second area of the collaboration window, the mouse pointer is displayed in a second shape. In this way, the second device can dynamically configure a display shape of the pointer of the second device in the collaboration window based on pointer shape information.
