Projection Window Gesture Conversion for Reliable Edge Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of inconvenient operation when controlling a source projection device using a bezel-less screen gesture on a destination projection device is exacerbated by the increasing screen-to-body ratio and bezel-less screens, leading to difficulty in triggering edge slide gestures effectively.
Innovation Solution
The method involves converting a touch slide event from outside a projection window to an edge slide event of the source projection device by detecting a target area extending outward from the projection window edge, allowing the destination projection device to generate an edge slide event and send it to the source device, thereby improving the success rate of edge slide gesture detection.

Engineering Contradiction Analysis
1Area of moving object
If a bezel-less screen gesture is used to control the source projection device, then the screen-to-body ratio is increased and the appearance is improved, but the ease of operation deteriorates because the edge slide gesture cannot be triggered effectively
Solution Approach 1:
The patent extends the gesture detection area from the traditional screen edge into the projection window area. By defining a target area that includes both the projection window edge and an extension area, the system enables edge slide gesture detection in a new spatial dimension, allowing users to trigger gestures from outside the projection window boundary while maintaining the bezel-less appearance.
2Device complexity
If the edge slide gesture detection area is limited to the projection window edge, then the device complexity is reduced, but the reliability of gesture detection deteriorates because the success rate is low
Solution Approach 1:
The patent performs preliminary action by pre-defining the target area that includes both the projection window edge and the extension area before gesture detection occurs. This preliminary configuration ensures that when a user performs a touch slide operation, the system can immediately recognize it as a valid edge slide gesture without requiring complex real-time calculations, thereby improving detection reliability while maintaining manageable system complexity.
3Ease of operation
If the target area for gesture detection is extended outward from the projection window edge, then the ease of operation is improved, but the device complexity increases due to additional area definition and event conversion logic
Solution Approach 1:
The patent introduces an intermediary mechanism - the event conversion module - that translates touch slide events from the extended target area into edge slide events. This intermediary layer handles the complexity of coordinate transformation and event mapping, allowing the system to benefit from the extended detection area while encapsulating the computational complexity within a dedicated processing module.

AI summary
A device control method includes: a destination projection device, after displaying a projection window of a source projection device, that generates a touch slide event in response to a touch slide operation performed by a user by sliding from outside the projection window to inside the projection window, and when a start touch point of the touch slide operation is located in a target area, converts the touch slide event into an edge slide event of the source projection device, and then sends the edge slide event to the source projection device, where the target area is an area formed by extending a preset distance outward from an edge of the projection window; and the source projection device updates screen display content based on the edge slide event after receiving the edge slide event.
