Touch-Activated Window Scaling via Pressure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch operations on image display apparatuses are poorly operable due to the difficulty in accurately targeting the small edge or corner of a window, and lack of visual feedback, making it hard to simultaneously change both the height and width of a window effectively.
Innovation Solution
An information processing apparatus and method that detects touch operations and pressure information within a predetermined area, allowing for selective execution of window size changing and image size changing processes based on touch pressure, with visual feedback through notification pointers to guide the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user performs a drag operation on an edge of a window to change its size, then the window size can be adjusted, but it is difficult to accurately touch the edge area and operation errors occur easily
Solution Approach 1:
The patent changes the parameter of touch pressure to differentiate between window size changing and image size changing operations. By detecting whether the touch pressure exceeds a threshold value, the system determines which operation the user intends to perform, eliminating the need to precisely target edge areas.
Solution Approach 2:
The patent introduces pressure information as an intermediary parameter to mediate between the user's touch operation and the system's response. This intermediary allows the system to distinguish between different operational intents (window resizing vs. image zooming) based on pressure levels rather than requiring precise positional accuracy.
2Ease of operation
If a user performs a pinch-in and pinch-out operation to enlarge and reduce an image in a window, then the image size can be adjusted, but it is not possible to improve the operability of touch operation of changing both height and width of window simultaneously
Solution Approach 1:
The patent uses touch pressure as a parameter to differentiate between two distinct operations: when pressure exceeds the threshold, window size changing is activated; when pressure is below the threshold, image size changing is activated. This allows a single touch interface to provide multiple functions with clear differentiation.
Solution Approach 2:
The patent makes the touch operation universal by enabling both window size changing and image size changing through the same pinch-in and pinch-out gesture. The only difference required from the user is the applied pressure level, making the interface more versatile and reducing the need to learn multiple separate gestures.
3Ease of operation
If a mouse cursor display is changed in response to mouse-over state to help user understand the process, then ease of operation is improved, but it is not possible to create a state corresponding to mouse-over state in touch operation
Solution Approach 1:
The patent implements feedback by displaying notification pointers that indicate which operation will be performed based on the detected touch pressure. This visual feedback helps users understand the system's interpretation of their touch gesture and confirms the intended operation before execution.
Solution Approach 2:
The patent uses different colored notification pointers (first notification pointer for window size changing, second notification pointer for image size changing) to provide visual feedback. The color or type of notification pointer changes based on the detected touch pressure, helping users distinguish between different operational modes.
