Projected Image Movement Indicators for Off-Screen Change Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in understanding whether their operations on an information processing device are reflected in the image projected by a projection device, especially when parts of the image are displayed off the projection target, leading to unclear changes in the projected image.
Innovation Solution
A display method involving an information processing device that projects a first image and displays a second image on a separate display device, where a movement indicator is shown when the position of a figure is moved, allowing the user to see the change reflected in the projected image.

If the projection device projects images off the projection target screen, then the projection coverage is increased, but the user cannot recognize changes in the projected image
Solution Approach 1:
The patent introduces a display device as an intermediary that shows a second image corresponding to the projected first image. When the projection position changes, the display device updates the second image to reflect these changes, allowing users to recognize image modifications even when the projected image moves off the projection target screen.
Solution Approach 2:
The system implements feedback by displaying a second image on a separate display device that reflects the state of the projected first image. When the projection position is adjusted, the display device provides visual feedback showing the corresponding changes, enabling users to understand how the projected image has moved or changed position.
2Ease of operation
If the information processing device operates remotely to correct the projected image, then the operation convenience is improved, but the user cannot understand whether the operation results are reflected on the projected image
Solution Approach 1:
The display device provides real-time feedback by updating the second image to reflect changes in the projected first image. When users perform remote operations to adjust the projected image, the display device immediately shows the corresponding changes in the second image, allowing users to understand whether their operations have been reflected.
Solution Approach 2:
The system creates a copy (second image) of the projected image (first image) and displays it on a separate display device. This copy updates in response to projection changes, providing users with a visible representation of the projected image state without requiring them to physically approach the projection target.

AI summary
There is provided a display method including projecting a first image including a first figure from a projection device, displaying, with an information processing device, a second image including a second figure corresponding to the first figure on a display device different from the projection device, when moving operation of moving the position of the first figure is received by the information processing device, causing the information processing device to display, on the second image, in correlation with the second figure, a movement indicator indicating that the first figure is moved in the first image, and projecting the first figure after the movement from the projection device.
