Gaze-Aware Display Focus Retention During Layout Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices fail to maintain user focus on a specific part of interest on the screen when the orientation is switched, leading to the user missing the highlighted item after a screen layout change.
Innovation Solution
The electronic device employs a line-of-sight detection system to identify the user's focus point, ensuring that the previously highlighted item remains identifiable on the screen after orientation changes, using techniques such as highlight display, color changes, or animation to draw attention to the focused item.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen layout is switched (orientation change), then the display adapts to new orientation, but the previously focused item becomes difficult to locate
Solution Approach 1:
The system stores the focused item's identification information before the screen layout switching occurs. This preliminary action ensures that even though the visual position changes, the system retains knowledge of which item was focused, allowing it to be重新 highlighted after the switch.
Solution Approach 2:
After screen layout switching, the system uses the stored focused item information to provide feedback by automatically highlighting or repositioning the cursor to the previously focused item. This feedback mechanism ensures the user can immediately locate their previously focused content without manual searching.
2Adaptability or versatility
If the screen layout is switched, then the display adapts to new orientation, but the user may miss the focused item
Solution Approach 1:
The system performs preliminary storage of the focused item's identification information before layout switching. This ensures that the focused item can be reliably reconstructed in the new layout, preventing the user from missing it during the transition.
Solution Approach 2:
The system provides automatic feedback by highlighting or repositioning the cursor to the previously focused item after layout switching. This feedback mechanism significantly improves the reliability of item visibility, ensuring the focused item remains noticeable throughout the orientation change.
3Ease of operation
If the line-of-sight detection is used to identify focused position, then the focused item can be highlighted, but the system complexity increases
Solution Approach 1:
The patent uses line-of-sight detection technology as an intermediary to bridge the user's visual attention and the system's focus identification. By detecting where the user is looking rather than requiring explicit input, the system achieves ease of operation while the complexity is encapsulated in the detection module itself.

AI summary
An electronic device according to the present invention includes a processor, and a memory storing a program which, when executed by the processor, causes the electronic device to execute acquisition processing of acquiring information related to a line-of-sight position of a user, and execute control processing of performing control to display a screen and performing control to identifiably display an item corresponding to a focused position of the user on the screen based on the information related to the line-of-sight position, wherein, in a case where a layout of the screen is switched, in the control processing, regardless of a focused position of the user on the screen after the switching, control is performed so that an item that is identifiably displayed before the switching is identifiably displayed on the screen after the switching.
