Projector Position Detector for Intuitive Image Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector systems lack intuitive and easy-to-use functionality for controlling image projection configurations, such as expansion, contraction, and translation, when an operation is performed on the projected image.
Innovation Solution
A projector system equipped with a position detector and a projection controller that allows for intuitive control of image projection configurations, including expansion, contraction, and translation, by detecting an indicated position on the projection surface and performing corresponding operations within a predetermined operation area.

Engineering Contradiction Analysis
1Ease of operation
If the projector displays an image on the projection surface, then the image projection function is achieved, but the operability for controlling projection configuration (expansion, contraction, translation) is poor
Solution Approach 1:
The position detector serves multiple functions: it detects indication positions for pointer display and simultaneously detects operations for controlling projection configuration. This multi-functionality improves operability by allowing users to control projection settings through intuitive position indication on the projected image itself, rather than requiring separate control devices.
Solution Approach 2:
The projection surface acts as an intermediary medium. Instead of requiring direct physical interaction with the projector or separate control interfaces, users interact with the projected image on the surface, and the position detector translates these interactions into control commands for projection configuration adjustment.
2Adaptability or versatility
If a pointer or indication is displayed at an arbitrary position, then the indication function is achieved, but additional functions such as process control cannot be performed
Solution Approach 1:
The position detector integrates multiple functions into a single system: it provides pointer indication at detected positions and simultaneously enables control of projection configuration processes. This allows the same interaction mechanism to serve both indication and control purposes, enhancing functionality while maintaining operational intuitiveness.

AI summary
A projector controls a function in accordance with an operation of indicating a position if the operation is performed in a state in which an image is displayed. The projector projects an image on a screen based on a supply image supplied by an image source. The projector detects a position indicated on the screen using a position detector, and switches the projector between a first interactive mode and a second interactive mode based on the detected position, wherein when the first interactive mode is selected, an output switching section outputs the position information to a processing section of the projector, and when the second interactive mode is selected, the output switching section outputs the position information to an external device connected with the projector.
