Attention Detection for Moving Image Reproduction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reproducing apparatuses for moving image data require users to repeatedly select and operate buttons or remote controls for switching reproduction operations, making it difficult to perform desired reproduction operations, especially in head-mounted displays where the operating section is hard to view, complicating the process.
Innovation Solution
A reproducing apparatus with an attention position detection section to determine the user's focus direction and a reproduction control section that controls the reproduction based on the importance level of virtual division areas, allowing users to control the reproduction operation by moving their attention, with features like automatic setting of reproduction images and decoding processing according to importance levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users operate reproduction apparatus by selecting buttons or using remote control, then reproduction operations can be performed, but the operation process becomes complicated and difficult to perform desired operations easily
Solution Approach 1:
The reproduction apparatus automatically determines reproduction operations based on detected attention positions without requiring user input. The system serves itself by using sensors to detect where the user is looking and automatically controlling reproduction based on pre-set importance levels of different image regions, eliminating the need for manual button operations
Solution Approach 2:
The patent replaces mechanical button-pressing operations with an optical/electronic attention detection system. Sensors detect the user's line of sight and head direction, substituting the mechanical interaction (buttons, remote control) with an automatic optical detection and control system that interprets attention position to determine reproduction operations
2Adaptability or versatility
If display section is worn on head (head-mounted display), then portability and viewing experience are improved, but the operating section becomes hard to view and attachment/detachment is necessary
Solution Approach 1:
The patent extracts the operating section from the head-mounted display device itself and relocates it to a remote control apparatus or external device. This allows the display to remain compact and wearable while the controls are accessible elsewhere, separating the viewing function from the control function
Solution Approach 2:
The patent introduces an intermediary attention detection system that mediates between the user's natural viewing behavior and the reproduction control. Instead of requiring direct interaction with controls, the system uses sensors to detect attention position and translates this into reproduction operations, bridging the gap between the wearable display and control functionality

AI summary
An attention position detection section detects an attention position of a user to a reproduction image of moving image data. Image-related information indicating a position of a virtual division area in which the reproduction image is virtually divided and an importance level of the virtual division area is associated with the moving image data. A reproduction control section determines the importance level of the virtual division area corresponding to the attention position detected by the attention position detection section and controls a reproduction operation of the moving image data in accordance with the determined importance level. For example, the reproduction control section sets a larger number of images to be thinned in the reproduction operation as the importance level becomes lower so as to make the reproduction speed faster. The user can control the reproduction operation only by moving the attention position and easily perform the appropriate reproduction operation.
