Multi-Unit Projection Device Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projection technologies are inconvenient and complex for users to adjust the projection region, leading to poor user experience due to the need for direct operation of the projection device.
Innovation Solution
A method and electronic device with multiple projection units that allow for adjusting the projection region through gesture, touch, or voice control, enabling users to project content onto different regions by detecting operations and determining the appropriate projection units to achieve seamless adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user directly operates the projection device to adjust the projection region, then the projection region can be adjusted, but the operational process becomes complex and inconvenient
Solution Approach 1:
The patent introduces an image processing unit that detects operations on the projection content itself as an intermediary between the user and the projection device. When users perform operations like dragging or pinching on the projected image, the system automatically translates these into projection region adjustments, eliminating the need for direct device manipulation and simplifying the operational process
Solution Approach 2:
The projection device enables self-service operation by allowing users to directly manipulate the projection content (image) to adjust the projection region. The system automatically detects these manipulations and adjusts the projection accordingly, making the device responsive to natural user actions without requiring complex control mechanisms
2Ease of operation
If the user performs pressing or rotating operations on buttons to adjust projection region, then the projection region can be changed, but the operation becomes difficult to control
Solution Approach 1:
The patent replaces mechanical button operations with touch-based interactions on the projection content itself. Users can directly touch, drag, or pinch the projected image to adjust the projection region, providing more intuitive and precise control compared to mechanical buttons. The touch screen detects these gestures and translates them into accurate projection region adjustments
3Adaptability or versatility
If multiple projection units are used to project content on different sides, then multiple users can view simultaneously, but adjusting which unit projects which content becomes complex
Solution Approach 1:
The system implements feedback mechanisms where the touch screen detects user operations on specific projection content and automatically determines which projection unit should handle that content. The system provides visual feedback by displaying operation prompts on the touch screen and automatically switches projection units based on detected gestures, simplifying the management of multiple projection units

AI summary
A projection method and an electronic device are provided. The method includes: projecting a first projection content from a first projection unit; determining at least one second projection unit of the electronic device in the presence of a first operation; and projecting the first projection content from the at least one second projection unit.
