Touch Gesture Input for Efficient Object Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manipulating collections of objects on touch-sensitive surfaces, such as chart portions, are cumbersome and inefficient, leading to a significant cognitive burden and energy wastage, particularly in battery-operated devices.
Innovation Solution
Implementing touch-based gestural user inputs on devices with touchpads or touch screens, allowing for the selection and manipulation of multiple objects through sequential movements and pauses, enabling faster and more efficient interaction with graphical user interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mouse-based inputs are used to select and manipulate collections of objects, then manipulation capability is achieved, but cognitive burden and time consumption increase significantly
Solution Approach 1:
The patent replaces the mechanical mouse-based input system with a touch-sensitive surface that detects finger gestures. The system substitutes complex multi-step mouse operations (click, drag, select, manipulate) with intuitive touch gestures (tap, swipe, pinch, rotate), thereby reducing cognitive burden and time consumption while maintaining full manipulation capability.
Solution Approach 2:
The patent introduces dynamic gesture recognition that adapts to user interactions in real-time. The system detects continuous gestures (swiping, pinching, rotating) rather than discrete clicks, allowing fluid and intuitive manipulation of object collections. This dynamic approach enables users to select and manipulate multiple objects through continuous motion, significantly reducing the time and cognitive effort required compared to sequential mouse operations.
2Ease of operation
If sequential mouse-based inputs are used for object manipulation, then selection and manipulation functions are achieved, but energy consumption increases
Solution Approach 1:
The patent replaces energy-intensive mouse-based input with touch-sensitive surface gestures. The touch interface detects user interactions more efficiently, reducing the number of discrete input cycles and processing operations required. This substitution leads to lower energy consumption while maintaining ease of manipulation, which is particularly important for battery-operated devices.
3Ease of operation
If conventional mouse-based methods are used, then object selection and manipulation are possible, but cognitive burden on users increases significantly
Solution Approach 1:
The patent substitutes complex mouse-based operation sequences with intuitive touch gestures that map directly to manipulation intentions. Users naturally tap to select, swipe to move, pinch to zoom, and rotate to rotate objects. This gesture-based system reduces cognitive burden by eliminating the need to learn and remember complex mouse operation sequences, while maintaining full manipulation capability.
Solution Approach 2:
The patent implements dynamic gesture recognition that adapts to user interactions in real-time. The system continuously monitors touch movements and automatically interprets gestures (swiping, pinching, rotating) as manipulation commands. This dynamic interpretation reduces cognitive burden by eliminating the need for users to consciously execute discrete selection and manipulation steps, making the interface more intuitive and easier to use.

AI summary
A method includes: displaying a collection of objects; detecting a gesture made by a contact on the touch-sensitive surface, the gesture comprising a first movement of the contact on the touch-sensitive surface followed by a pause in movement of the contact followed by a second movement of the contact on the touch-sensitive surface; selecting a plurality of objects in the collection of objects in accordance with the first movement; and, after detecting the pause in movement of the contact, moving the selected plurality of objects away from unselected objects in the collection of objects in accordance with the second movement.
