Touch Input Object Relocation for Accurate Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with touch interfaces, narrow gaps between target objects and surrounding objects can lead to inaccurate selection or execution of unintended objects due to the difficulty in precise touch input, resulting in user intention misinterpretation.
Innovation Solution
A terminal apparatus and method that detects touch inputs, identifies objects overlapped by a reference percentage in the touched region, generates and displays secondary objects in untouched regions based on the first objects, and executes operations corresponding to these secondary objects, ensuring accurate selection and execution by adjusting their size and position to avoid obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If objects are displayed with narrow gaps to maximize screen utilization, then the area for displaying objects is improved, but the accuracy of touch input selection deteriorates
Solution Approach 1:
The patent introduces an intermediary selection region between the user's touch input and the target object. When a touch is detected, the system highlights a region corresponding to the touch location, and only objects within this highlighted region are considered for selection. This intermediary mechanism allows objects to be displayed with narrow gaps while maintaining accurate selection, as the selection is based on the highlighted region rather than direct proximity to the touch point.
2Ease of operation
If the target object is highlighted at the touched location, then the ease of operation is improved, but the visibility of the actual target object deteriorates due to obstruction
Solution Approach 1:
The patent resolves the visibility conflict by displaying the target object in a different dimension or location. Instead of highlighting the object at its original position where it would be obscured by the touch input, the system displays the target object in an untouched region of the screen. This dimensional relocation allows the highlight to indicate the target without blocking the user's view of the actual object.
3Speed
If the target object is displayed in the touched region, then the response speed is improved, but the ease of operation deteriorates due to obstruction by the input device
Solution Approach 1:
The patent relocates the target object display to an untouched region of the screen, separate from the touch input location. This spatial separation in another dimension allows the system to maintain fast response by immediately displaying the target object upon touch detection, while simultaneously improving ease of operation by ensuring the target object is not obscured by the user's finger or input device.

AI summary
A terminal apparatus includes an interface to detect a touch input, to detect a touch region corresponding to the touch input, and to identify an object that is overlapped by the touch input by at least a reference percentage in the touch region as a first object; a processing unit to generate a second object based on the first object, and to display the second object in an untouched region; and a control unit to execute an operation corresponding to the second object. A method for executing an operation according to a touch input includes detecting a touch input and a corresponding touch region; identifying an object overlapped by at least a reference percentage in the touch region as a first object; generating a second object based on the first object; displaying the second object in an untouched region; and executing an operation corresponding to the second object.
