Adaptive Touch Operators for Precise In-Vehicle Value Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices with slider bars for precise volume adjustment require longer user gaze time, which is undesirable, and are challenging to operate effectively during manual vehicle operation where finger shaking due to vibration occurs.
Innovation Solution
An information processing device with a determination unit to assess the ease of touch operation and a display control unit to switch between a precise slider bar operator and a coarse button operator based on the operation state, thereby optimizing gaze time and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a slider bar is used for precise value adjustment, then manufacturing precision is improved, but ease of operation deteriorates due to longer gaze time required
Solution Approach 1:
The system dynamically switches between slider bar and button operator based on detected operation ease state. The determination unit assesses whether touch operation is easy or difficult, and the display control unit adapts the operator type accordingly, making the interface flexible rather than static
Solution Approach 2:
The system changes the operational parameters of the value adjustment mechanism by switching between two distinct operator types (slider bar for precise adjustment, buttons for quick adjustment). This parameter change allows the system to optimize for either precision or speed depending on current conditions
2Manufacturing precision
If a slider bar is used for precise value adjustment, then manufacturing precision is improved, but productivity deteriorates due to longer operation time
Solution Approach 1:
The operator type is dynamically adjusted based on the determined operation state. When operation is easy, slider bar enables precise adjustment; when operation is difficult, buttons enable faster adjustment, optimizing productivity for current conditions
Solution Approach 2:
The system changes the adjustment granularity parameter by switching between slider bar (fine adjustment) and buttons (coarse adjustment). This allows the system to prioritize speed when needed while maintaining precision capability when conditions permit
3Ease of operation
If a button operator is used for quick value adjustment, then ease of operation is improved with shorter gaze time, but manufacturing precision deteriorates
Solution Approach 1:
The system switches between button operator and slider bar based on operation ease determination. When the determination unit detects easy operation conditions, it activates the slider bar to provide precise adjustment capability
Solution Approach 2:
The system adjusts the value unit parameter dynamically - using larger value units with buttons for quick adjustment when operation is difficult, and smaller value units with slider bar when operation is easy, thus optimizing the precision-speed tradeoff

AI summary
An information processing device having a determination unit for determining whether a current state is a first state wherein a touch operation on a screen of a display device is easy for a user, or a second state wherein the touch operation is less easy for the user than when in the first state; and a display control unit that displays a first operator for adjusting a value related to content on the screen of the display device when in the first state, and displays a second operator for adjusting a value related to the content on the screen when in the second state. The first operator is capable of adjusting a value related to the content in a first value unit according to the touch operation, and the second operator is capable of adjusting a value related to the content in a second value unit larger than the first value.
