Engineering Contradiction Analysis
1Measurement precision
If the display device performs unit operations for each wheel event, then the operation precision is high, but the productivity is low due to frequent discrete operations
Solution Approach 1:
The system dynamically adjusts the operation mode between unit operations and continuous operations based on the detected rotation speed of the wheel input device. When rotation speed exceeds the reference speed, continuous operations are performed; when it is below the reference speed, unit operations are performed. This dynamic adaptation resolves the contradiction by allowing the system to optimize between precision and speed based on actual user input characteristics.
Solution Approach 2:
The system changes the operational parameter (operation mode) based on the rotation speed parameter of the wheel input device. By monitoring the rotation speed and switching between unit and continuous operations, the system achieves both high precision when needed and high productivity when appropriate, resolving the technical contradiction between operation precision and productivity.
2Productivity
If the display device performs continuous operations based on wheel rotation speed, then the productivity is improved, but the measurement precision of rotation speed detection must be high
Solution Approach 1:
The system continuously monitors the rotation speed of the wheel input device and uses this feedback to determine whether to perform continuous or unit operations. By implementing feedback-based control, the system ensures that continuous operations are only performed when the rotation speed reliably exceeds the reference speed, thus maintaining measurement precision while achieving high productivity when conditions are appropriate.
3Adaptability or versatility
If the display device switches between unit and continuous operations, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The system performs preliminary detection of the rotation speed before deciding on the operation mode. By pre-establishing the reference speed threshold and detecting whether the current rotation speed exceeds it, the system simplifies the control logic while maintaining high adaptability. This preliminary action approach allows the system to switch between operation modes based on a clear, pre-defined criterion rather than complex real-time analysis.

AI summary
A user interface device and method for controlling a screen by a wheel input signal in a display device. The display device, based on wheel events that continuously occur according to manipulation of a wheel input device by a user reaching a reference number, obtains an average interval of intervals between occurrence times at which the wheel events occur, respectively. The display device displays a result of performing a continuous operation through a display based on the obtained average interval being shorter than a reference interval.
