Eye Gaze Indicator Control with Time-Locked Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses that move a mouse pointer based on eye gaze input often result in unintended pointer movement due to user unawareness of elapsed time, leading to usability issues.
Innovation Solution
An electronic apparatus with a processor and memory that receives eye gaze input and controls an indicator's movement based on specific operation conditions, locking the pointer at the eye gaze input position unless a second condition is met, allowing for precise control and preventing unintended movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the pointer is moved to the eye gaze input position and fixed for a predetermined time, then the pointer can be positioned accurately at the desired location, but the user may be unaware that the predetermined time has elapsed causing unintended pointer movement
Solution Approach 1:
The system provides visual feedback by displaying a timer or indicator showing the remaining time before the pointer automatically moves. This allows the user to be aware of the elapsed time and make an informed decision whether to continue the operation or interrupt it, thereby preventing unintended pointer movement while maintaining accurate positioning capability
Solution Approach 2:
The system performs a preliminary action by moving the pointer to the eye gaze input position and holding it there for a predetermined time, during which the user can confirm or cancel the operation. This preliminary holding phase allows the user to react before the automatic movement occurs, balancing positioning accuracy with user awareness
2Stability of the object's composition
If the pointer is fixed at the eye gaze input position for a predetermined time, then positioning stability is improved, but the operation time is extended due to waiting for the predetermined time to elapse
Solution Approach 1:
The system dynamically adjusts the pointer behavior based on user input. If the user performs a continuous operation (e.g., continuous mouse movement), the pointer moves immediately without waiting for the predetermined time, thus reducing operation time. If the user stops the operation, the pointer waits for the predetermined time to ensure positioning stability. This dynamic response optimizes both stability and time efficiency
3Speed
If the pointer moves in response to continuous operation on the pointing device, then the pointer can be repositioned quickly, but the pointer may move to a position different from what the user intended
Solution Approach 1:
The system applies preliminary anti-action by preventing the pointer from moving in response to continuous operation when the predetermined time has not yet elapsed. The pointer is locked at the eye gaze input position during this period, counteracting the natural tendency of the pointer to follow continuous pointing device operations. This prevents the pointer from moving to unintended positions while still allowing quick repositioning after the user confirms the operation

AI summary
An electronic apparatus includes a reception unit configured to receive an eye gaze input based on an eye gaze of a user. In a case where the eye gaze input is received by the reception unit, a control unit performs control to move an indicator to a position based on the eye gaze input if an operation performed on an operation unit satisfies a first condition, not to move the indicator if the operation performed on the operation unit satisfies the first condition but does not satisfy a second condition after moving the indicator to the position based on the eye gaze input, and to move the indicator from the position based on the eye gaze input by a movement amount corresponding to an operation amount if the operation performed on the operation unit satisfies the second condition.
