Electronic Device Block Setting via Dual Touch Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accurately setting blocks on electronic devices due to the text window being obscured by their fingers during interaction, making it hard to select and drag the ends of the block effectively.
Innovation Solution
An electronic device method that senses a first touch input to set content as a block, with a second touch input allowing movement to define the block's boundaries, displaying a cursor and allowing touch input on a keypad to control the block's placement and selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user performs long-press and drag operations to set a block, then the block can be selected and manipulated, but the text window becomes obscured by the user's finger making accurate setting difficult
Solution Approach 1:
The patent introduces visual indicators (highlighting/shadow effects) as intermediaries between the user's touch input and the block selection. When the user performs a long-press, the system displays a visual indicator showing the block boundaries without requiring the user to see the text through their finger. This mediator provides feedback about the selected block while the finger obscures the original text view.
Solution Approach 2:
The system provides real-time visual feedback during the block selection process. As the user drags their finger to define block boundaries, the system continuously updates the visual indicator to show the current selection extent. This feedback mechanism allows users to accurately control block boundaries even though the text window is obscured by their finger.
2Ease of operation
If the user touches and drags the left end or right end of the block, then the block can be repositioned, but it is difficult to accurately touch the left end and right end of the text window
Solution Approach 1:
Before the user attempts to drag the block, the system performs preliminary action by displaying visual indicators that clearly mark the block boundaries (left end and right end). These indicators are positioned and sized to be easily distinguishable and touchable, providing clear targets for the user's finger before the dragging operation begins.
Solution Approach 2:
The patent applies local quality by enhancing the visual properties of the block boundaries with distinctive indicators (such as thicker borders, different colors, or shadow effects). This makes the left end and right end of the block locally distinct and easier to identify and touch accurately, compared to the rest of the text area.

AI summary
Methods and apparatuses are provided for setting a block in an electronic device. Content is displayed on a display of the electronic device. The electronic device senses a first touch input on an area for setting the displayed content in the display as a block. The electronic device senses a second touch input while the first touch input is maintained on the area. The electronic device sets at least a part of the content as the block, based on a movement of the second touch input.
