Gaze Point Indicator Display Order Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing line-of-sight input technologies for electronic devices do not effectively allow users to easily view and confirm the designated position based on their gaze point, leading to potential misalignment and user annoyance due to constantly displayed pointers.
Innovation Solution
An electronic device with a detection unit to identify the user's gaze point and a control unit to display an indicator, which changes the display order of items on the screen to prioritize the gaze point and indicator, allowing for intuitive operation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pointer indicating the gaze point is always displayed, then the user can check the gaze point position, but the target displayed object becomes difficult to view and the user feels annoyed
Solution Approach 1:
The display order of the indicator and display items is changed dynamically based on operation state. Before determination operation, the indicator is displayed above display items to show gaze point. After determination operation, the display items are displayed above the indicator to make targets easily viewable, while the indicator remains visible to confirm the designated position.
2Ease of operation
If the gaze point is not displayed, then the display is clean and unobtrusive, but the user cannot check whether the gaze point corresponds to the intended position
Solution Approach 1:
The system dynamically adjusts the display order based on operation phase. In the state before determination operation, the indicator is prioritized to enable gaze point verification. After determination operation, display items are prioritized to maintain clean display while the indicator remains visible for position confirmation.
3Ease of operation
If display items are always prioritized over the indicator, then the target objects are easily viewable, but the gaze point position becomes difficult to confirm
Solution Approach 1:
The display order is switched based on operation state. Before determination operation, the indicator is displayed above display items to confirm gaze point. After determination operation, display items are displayed above the indicator to improve target visibility, while the indicator remains visible to confirm the designated position.

AI summary
In an operation by line-of-sight input, a position (designated position) designated by a gaze point is easier to view after a determination operation is performed by a user than before the determination operation is performed. An electric device includes a detection unit configured to detect a gaze point, which is based on line-of-sight of a user viewing, on a display unit, and a control unit configured to display an indicator on the display unit indicating the gaze point, wherein in a case where an operation is performed on an operation unit by the user, the control unit performs control to display a display item at the gaze point and to display the indicator and the display item in a changed display order.
