Operation Terminal Control Device Angle Detection Input Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operation terminal control devices do not effectively prevent user discomfort during input operations and display viewing, particularly when the terminal is not held at a comfortable angle or when the user's gaze direction is not aligned with the vehicle's direction.
Innovation Solution
Incorporating an angle detection unit and a control unit that limits input and display operations when the terminal is not held within a predetermined angle range and the gaze direction is not within a predetermined range, while providing point-adding or point-subtracting elements in games to encourage optimal usage positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation terminal is held at an arbitrary angle, then the user can operate the terminal freely, but the user is more likely to feel discomfort and experience motion sickness
Solution Approach 1:
The system changes the operational parameters by detecting the holding angle of the terminal and dynamically adjusting input operation availability based on whether the angle falls within a predetermined comfortable range. When the angle is outside the comfortable range, input operations are limited to prevent motion sickness while maintaining freedom of operation within acceptable parameters.
2Ease of operation
If the display unit is viewed at an arbitrary angle, then the user can view the display freely, but the user is more likely to feel discomfort and experience motion sickness
Solution Approach 1:
The system detects the viewing angle of the display unit and changes the operational state based on whether the angle is within a comfortable viewing range. When outside the comfortable range, display operations are limited to reduce motion sickness while preserving viewing freedom within acceptable angular parameters.
3Adaptability or versatility
If input operations and display viewing are performed at arbitrary angles, then the user has operational flexibility, but the user is more likely to feel discomfort
Solution Approach 1:
The system dynamically adjusts input operation availability and display operations based on real-time detection of holding and viewing angles. The control unit changes operational states from full functionality to limited functionality depending on whether angles are within comfortable ranges, maintaining adaptability while preventing discomfort.
Solution Approach 2:
The system changes operational parameters by monitoring angular parameters and adjusting input and display functions accordingly. When angles fall outside comfortable ranges, operations are limited to prevent motion sickness while maintaining flexibility within acceptable parameter ranges.
4Adaptability or versatility
If the terminal is held outside the comfortable angle range, then the user can position the terminal freely, but the user is more likely to perform operations that cause motion sickness
Solution Approach 1:
The system takes preliminary action by detecting the holding angle before allowing input operations. When the angle is outside the comfortable range, the control unit preemptively limits input operations to prevent motion sickness from occurring in the first place, rather than addressing symptoms after they arise.
Solution Approach 2:
The system changes operational parameters based on detected holding angles. When outside comfortable ranges, input operations are restricted to prevent motion sickness while preserving positioning freedom within acceptable angular parameters.

AI summary
An angle detection unit for detecting a first angle, which is a relative angle of a display unit capable of displaying an image provided on an operation terminal held by a user, with respect to a first predetermined direction; and when the first angle is not within a first range. and a control unit that limits either or both of an input operation by the user to the input unit provided in the operation terminal and a display operation of the display unit compared to when the first angle is within the first range.
