Collaboration Window Pointer Control for Text and Image Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collaboration window systems fail to dynamically adjust the shape of a mouse pointer based on the area it is in, leading to inconvenient user operations, such as text selection and image resizing, when using a mobile device to project its screen onto another device.
Innovation Solution
A method and system that dynamically configure the display shape of a mouse pointer in a collaboration window based on its position within different areas, such as text or image regions, by synchronizing pointer icon libraries and simulating mouse pointer inputs to adjust the pointer shape accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a collaboration window transmits only click events without mouse pointer shape information, then device complexity is reduced, but ease of operation deteriorates because users cannot perform text selection or image resizing operations
Solution Approach 1:
The patent introduces a pointer shape information transmission mechanism as an intermediary between the mouse input and the collaboration window display. The first device (mouse device) determines the current pointer shape based on mouse position and transmits this shape information to the second device (collaboration window device), which then displays the appropriate pointer shape. This intermediary mechanism enables text selection and image resizing operations without requiring complex event transmission protocols.
Solution Approach 2:
The system performs preliminary action by pre-determining the pointer shape based on the mouse position relative to different areas (text area, image area, etc.) before the user actually performs the operation. The first device calculates which pointer shape is needed based on the current mouse position, and this shape information is transmitted to the second device in advance, allowing the user to immediately perform text selection or image resizing when the mouse enters the appropriate area.
2Adaptability or versatility
If the mouse pointer shape is fixed regardless of position, then device complexity is reduced, but adaptability deteriorates because the system cannot respond to different operational contexts like text selection or image resizing
Solution Approach 1:
The patent implements dynamics by making the pointer shape changeable based on the mouse position. Instead of a fixed pointer shape, the system dynamically determines the appropriate pointer shape (text selection pointer, image resizing pointer, etc.) based on which area the mouse is currently over. The first device continuously monitors mouse position and updates the pointer shape information transmitted to the second device, enabling the collaboration window to adapt to different operational contexts.
Solution Approach 2:
The system applies local quality by assigning different pointer shapes to different areas within the collaboration window. Each area (text area, image area, etc.) has its own specific pointer shape that is appropriate for the operations needed in that area. When the mouse enters a specific area, the system transmits the corresponding pointer shape information to the second device, allowing the pointer to have locally appropriate characteristics for each region.

AI summary
Embodiments of this application provide 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.
