Touch Panel Operation Detection for Intuitive Command Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch panel systems require users to remember which operations correspond to specific commands, leading to reduced convenience and operability.
Innovation Solution
An information processing device with an operation detecting unit that differentiates between first and second touch operations on a touch panel based on coordinate information, allowing for intuitive changes in virtual line segment length or rotation angle, which are used to execute associated processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch panel operations are used to enter multiple commands, then the device can receive diverse user inputs, but the user must remember which operations correspond to which commands, reducing convenience
Solution Approach 1:
The system provides visual feedback by displaying icons corresponding to detected touch operations. When a user performs a touch operation, the system detects it and displays a relevant icon on the screen, allowing the user to see what command is being executed without having to remember operation-command associations
Solution Approach 2:
The system automatically identifies and displays the appropriate icon based on the touch operation detected, eliminating the need for the user to manually select or remember which command corresponds to which operation. The system serves itself by automatically providing the correct visual feedback
2Device complexity
If traditional touch panel operations are used, then the device structure remains simple, but the operability and user experience are limited
Solution Approach 1:
The system uses visual display of icons with different appearances to represent different touch operations. The icon display provides intuitive visual cues that enhance operability without adding physical complexity to the device structure
Solution Approach 2:
The system adds a visual dimension to touch panel operation by displaying icons that correspond to detected gestures. This transforms the interaction from purely tactile to a combination of tactile and visual feedback, improving operability while maintaining structural simplicity

AI summary
The information processing device includes: an operation detecting unit that determines that a first touch operation has been detected, calculates the length of a virtual line segment connecting the plurality of touched positions detected or the rotation angle with respect to a reference direction for the virtual line segment, and determines whether or not there has been a change in the length or rotation angle of a virtual line segment when coordinate information has been inputted, the touch panel displaying a second screen, and determines that a second touch operation has been detected when it has been determined that there has been a change in the length or rotation angle of the virtual line segment; and an execution instruction issuing unit that issues an instruction to execute the process associated with the change in the length of the virtual line segment or the rotation direction of the virtual line segment.
