Information Processing Apparatus Gesture Direction Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems lack an intuitive and user-friendly method to distinguish between operations for terminating and restricting the display of screen regions, leading to potential errors in erasing essential display areas.
Innovation Solution
An information processing apparatus that allows users to specify different directions to terminate or restrict the display of a display region, using touch sensors to detect movements and display operation guides, ensuring accurate user instructions are followed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single operation is used to both terminate and restrict display regions, then the operation method is simple, but it is impossible to distinguish between termination and restriction intentions
Solution Approach 1:
The patent segments a single gesture into two distinct phases: a first direction specification (for termination) and a second direction specification (for restriction). By dividing the operation sequence, the system can distinguish between different user intentions while maintaining gesture-based simplicity.
Solution Approach 2:
The patent introduces a temporal dimension by using sequential operations in different directions. The first direction specifies termination intent, and the second direction (opposite to the first) specifies restriction intent. This dimensional differentiation allows clear distinction between two operations.
2Reliability
If direction-based operations are used to distinguish termination and restriction, then operation accuracy is improved, but operation complexity increases
Solution Approach 1:
The patent applies local quality by assigning specific meanings to specific directions within the gesture space. The first direction (e.g., upward) is locally assigned to termination, while the opposite direction (e.g., downward) is locally assigned to restriction. This localized differentiation simplifies the overall operation model.
Solution Approach 2:
The patent uses inversion by making the second direction opposite to the first direction. This symmetric approach simplifies the operation model: one direction terminates, the opposite direction restricts. The inverted relationship provides intuitive understanding while maintaining operational accuracy.
3Ease of operation
If no visual feedback is provided during operation, then the interface is clean, but user understanding of current state is poor
Solution Approach 1:
The patent displays a guide image before the user performs the operation to preliminarily inform them of the operation target region. This advance information provision helps users understand what area will be affected without cluttering the interface during the actual operation.
Solution Approach 2:
The patent provides visual feedback by displaying guide images that indicate the operation target region and the current state (termination or restriction mode). This feedback mechanism maintains interface cleanliness while ensuring users have sufficient information to understand the operation context.

AI summary
Provided is an information processing apparatus that displays on a screen at least a part of a display region, in which display elements are arranged; terminates the display of the display region when an operation of specifying a first direction with respect to a predetermined region in the screen is received from a user; and shifts into a state, in which the termination of the display of the display region, when an operation of specifying a second direction that is different from the first direction with respect to the predetermined region is received from the user.
