Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If gesture recognition is used for operation on projection plane, then device portability is improved, but measurement precision deteriorates
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture the projection plane and display content. The camera transforms the physical gesture recognition problem into an image processing problem, allowing accurate content analysis even with small projection areas. The camera acts as a mediator between the user's gesture and the system's response, improving measurement precision without requiring larger devices.
2Device complexity
If camera-based gesture acquisition is used, then device complexity is reduced, but reliability deteriorates
Solution Approach 1:
The patent implements feedback by displaying the captured content back on the projection plane through the camera. This creates a closed-loop system where the system responds to user input and allows verification of the response accuracy. The feedback mechanism enables users to detect and correct error responses, improving overall system reliability while maintaining simple camera-based hardware.
3Measurement precision
If projection area is increased to improve gesture analysis accuracy, then measurement precision is improved, but device portability deteriorates
Solution Approach 1:
The patent transitions from analyzing gestures in the physical projection space to analyzing content in the digital image space captured by the camera. This dimensional transformation allows accurate content analysis independent of projection area size. The system operates in the two-dimensional image domain rather than being constrained by the physical projection area, enabling high precision with compact devices.

AI summary
The present invention discloses a display method, for determining user's operations and thereby reducing a rate of error response of electronic devices. The method includes determining a first image to be projected; projecting the first image, the first image being capable of forming on the touch sensing unit when the second electronic device is in the projection area and the touch sensing unit faces towards the first electronic device; receiving first operation information transmitted by the second electronic device, the first operation information being information acquired by the second electronic device in response to a first operation performed by a user on the touch sensing unit; determining a second image based on the first image and the first operation information; and projecting the second image. The present invention also discloses a display control method, and electronic devices for implementing the previously mentioned two methods respectively.
