Innovation Solution
A device and method that dynamically switches between a moving mode, a restricting mode, and a pressing mode based on user head motions, allowing continuous pointer operation and preventing unintended movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pointer movement is restricted after click operation, then unintended operations are prevented, but continuous input operation capability is reduced
Solution Approach 1:
The system dynamically switches between restricting mode and moving mode based on detected head motion patterns. After a click operation, the pointer transitions to restricting mode to prevent unintended operations, but when specific head motion is detected, it switches to moving mode to enable continuous input operations. This dynamic mode switching resolves the contradiction by adapting the pointer behavior to the user's actual operational needs.
Solution Approach 2:
The system uses motion sensors to detect head movements and provides feedback by switching between operating modes. The detection of specific head motion patterns triggers a switch from restricting mode to moving mode, creating a feedback loop that allows continuous operation when intended while maintaining protection against unintended operations. This feedback mechanism enables the system to distinguish between intentional continuous input needs and accidental movements.
2Productivity
If pointer movement is continuously allowed after click operation, then continuous input operation is enabled, but unintended operations increase
Solution Approach 1:
The system employs dynamic mode switching between moving mode and restricting mode based on real-time head motion detection. Instead of continuously allowing pointer movement, the system transitions to restricting mode after click operations and only switches to moving mode when specific head motion patterns are detected. This dynamic approach enables continuous operation capability while maintaining protection against unintended operations.
Solution Approach 2:
The motion sensor provides continuous feedback about head position and movement patterns. The system uses this feedback to determine when to switch from restricting mode to moving mode, creating an intelligent control mechanism that enables continuous input operations only when genuine user intent is detected through specific motion patterns, thereby preventing unintended operations.
3Device complexity
If operation mode is fixed after pressing mode, then system simplicity is maintained, but adaptability to different operation needs is reduced
Solution Approach 1:
The system automatically switches between operation modes based on detected head motion patterns without requiring manual user intervention. After a pressing operation, the system self-determines whether to transition to moving mode or restricting mode by monitoring subsequent head motions. This self-service approach maintains system simplicity while achieving high adaptability to different operational needs.
Solution Approach 2:
The operation mode is made dynamic rather than fixed, allowing automatic transitions between pressing mode, moving mode, and restricting mode based on real-time head motion detection. This dynamic behavior enables the system to adapt to different operation needs while maintaining simplicity through automated mode management without complex user controls.

AI summary
To improve usability for continuously operating the pointer, a device (eyewear device) according to an aspect of the disclosed technique is a device for operating an operation target device including a display screen (display). The device includes a processor (processing unit), and the processor executes: acquiring motion information on motion of a predetermined body part of a user from a sensor (6-axis sensor) mounted on the body part; controlling a pointer displayed on a display screen, based on an operation mode, which is set to one of (1) a moving mode in which a moving signal relating to moving, over the display screen, the pointer displayed on the display screen is transmittable to the operation target device, based on the motion information, (2) a restricting mode in which movement of the pointer on the display screen is restricted, and (3) a pressing mode in which a pressing signal relating to executing a pressing operation at a position of the pointer on the display screen is transmittable to the operation target device, based on the motion information; setting the operation mode to the pressing mode; and after setting the operation mode to the pressing mode, setting the operation mode after the pressing operation, to either the moving mode or the restricting mode, based on whether or not the motion information on a first motion to send the pressing signal and the motion information on a second motion after the first motion, out of the motion information acquired in the pressing mode, satisfies a first condition relative to the motion of the predetermined body part.
