Polygonal Object Touch Interface for One-Handed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in manipulating portable devices with increasing screen sizes due to the need for two hands to perform functions like scrolling, zooming, and navigating, leading to inconvenience and frequent device replacements.
Innovation Solution
A display apparatus featuring a polygonal object on the screen where different functions are mapped to its apexes, allowing users to perform actions like scrolling, zooming, and navigating by rotating the object with one hand, using a detecting unit and controller to execute corresponding functions based on touch manipulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the touch screen size is increased to display more information, then the display capability is improved, but the ease of operation deteriorates because two hands are required for manipulation
Solution Approach 1:
The patent divides the control functions into multiple apexes of a polygonal object displayed on the screen. Each apex represents a different function (scrolling, zooming, navigation, etc.), allowing the user to access different operations by touching different parts of the polygonal object with a single hand.
Solution Approach 2:
The patent adds a rotational dimension to the touch interface. By rotating the polygonal object after touching an apex, the user can perform different operations (e.g., scrolling in different directions, zooming in/out) without needing to use multiple hands or switch between different screen areas.
2Adaptability or versatility
If multiple functions are mapped to the screen, then the functionality is improved, but the ease of operation deteriorates due to the need for two-handed gestures like pinching
Solution Approach 1:
The patent makes the polygonal object a universal control interface that can perform multiple functions depending on which apex is touched and how it is rotated. The same polygonal object structure serves as a multi-functional controller for scrolling, zooming, navigation, and other operations, eliminating the need for separate gestures for each function.
Solution Approach 2:
The patent makes the control interface dynamic by allowing the polygonal object to rotate in response to user input. This rotation enables a single touch point to control multiple functions dynamically, with the rotation angle and direction determining the specific operation performed.

AI summary
A display apparatus is provided. The display apparatus includes a display unit configured to display a screen including a polygonal object onto which different functions are mapped according to apexes, a detecting unit configured to detect a touch manipulation, and a controller configured, in response to a manipulation by touching one of a plurality of apexes of the polygonal object to rotate the polygonal object, being detected through the detecting unit, to perform a function mapped onto the touched apex.
