Touch Screen Window Control via External Area Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartphones and tablets with touch screens face limitations in accurately changing window size and position due to their smaller screens and the large contact area of user input, such as fingers, making it difficult to precisely designate window boundaries and resize or reposition windows.
Innovation Solution
A display device and control method that allows users to change window size and position by inputting events into an external area of the window, using a controller to determine and execute window control events, enabling resizing, moving, minimizing, or setting window sizes, even with a wide contact area input like a finger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user's finger is used to input on the touch screen, then the input area is large and easy to operate, but the precision of designating window boundaries is poor
Solution Approach 1:
The touch screen is divided into multiple selectable areas including the window area and external areas surrounding the window. When a user touches an external area, the system segments the control function by displaying boundary adjustment guides that allow precise window resizing without requiring direct contact with the window boundaries themselves.
Solution Approach 2:
Boundary adjustment guides serve as an intermediary between the user's finger input and the window boundary. These guides are displayed in response to touching external areas and mediate the resizing operation, allowing the user to control window boundaries indirectly with finger tips rather than requiring precise direct contact with the boundaries.
2Volume of moving object
If the touch screen size is small, then the device is portable and compact, but the precision of window boundary designation is limited
Solution Approach 1:
The solution moves the interaction from the two-dimensional window boundary line to the surrounding external area. By allowing users to touch external areas and displaying boundary adjustment guides, the system adds a dimensional aspect to window control that enables precise boundary manipulation on small screens without requiring direct contact with the boundary lines themselves.
3Adaptability or versatility
If traditional window boundary dragging is used, then window size can be changed, but it is difficult to accurately designate the boundary on touch screens
Solution Approach 1:
The boundary adjustment function is extracted from the window boundary itself and relocated to external areas surrounding the window. When users touch these external areas, boundary adjustment guides are displayed, separating the selection action (touching external area) from the adjustment action (dragging along the guide), thereby improving boundary designation accuracy.

AI summary
A method of controlling a display device for displaying a window executing an application is provided. The method includes displaying the window, determining whether a window control mode for controlling an operation of the window is executed, determining whether a window control event for controlling the window is input into an internal area of the window, and controlling the window based on the determined window control event.
