Virtual Input Area Gesture Control for Large Display Ease of Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in controlling electronic devices with large screens using a single hand due to limitations in multi-touch and gesture recognition, especially when trying to zoom in or move objects across the display, as the size of the input area and finger movement range restrict precise interactions.
Innovation Solution
An electronic device method and apparatus that determines an input area on a display based on a gesture, adjusts functions according to the size, direction, intensity, and duration of the gesture, allowing for more intuitive control through advanced gesture recognition and area determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display size is increased to provide more information, then the information display capability is improved, but the ease of operation deteriorates due to limited finger movement range
Solution Approach 1:
The patent introduces a virtual input area that extends beyond the physical display boundaries by mapping touch inputs from a portion of the display to a larger virtual area. This dimensional mapping allows users to control the entire large display using a limited physical touch area, effectively resolving the contradiction between large display size and ease of operation.
Solution Approach 2:
The patent introduces a virtual input area as an intermediary between the user's finger and the display content. This virtual area acts as a mediator that translates limited physical touch movements into comprehensive control across the entire large display, enabling easy operation without requiring the user to reach across the full display area.
2Adaptability or versatility
If multi-touch and gesture recognition functions are added to enable various interactions, then the functionality is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal virtual input area that can handle multiple interaction types (single-touch, multi-touch, gestures) through a single unified mechanism. This approach provides diverse functionality without proportionally increasing system complexity, as the same virtual area framework supports various interaction modes.
Solution Approach 2:
The patent segments the display control into a virtual input area portion and the corresponding full display area. This segmentation allows the system to process complex multi-touch and gesture inputs within a manageable virtual space, then map them to the larger display, maintaining functionality while controlling complexity.
3Ease of operation
If the virtual input area is mapped to a portion of the display, then the ease of operation is improved, but the area coverage deteriorates
Solution Approach 1:
The patent creates a dimensional mapping where a small virtual input area portion corresponds to the entire large display area. This dimensional transformation allows users to control the full display area through limited physical touch movements, effectively resolving the contradiction between ease of operation and area coverage.

AI summary
An electronic device for controlling at least one function based on a user input, and a control method for the electronic device are provided. According to various example embodiments, an electronic device that operates based on a user input may acquire a gesture through an input area of a display unit functionally connected to the electronic device. The electronic device may perform at least one function of the electronic device, based on various variables (for example, a time period for which the gesture is sensed, a size of an area in which the gesture is sensed, a direction in which the gesture moves, or intensity at which the gesture is sensed, through the input area) corresponding to the acquired gesture. Various other example embodiments are disclosed.
