Grip Sensor Select-All Logic for Mobile Terminal Visual Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack intuitive user interfaces that effectively utilize grip sensors for controlling and interacting with visual information, limiting user convenience and efficiency in editing and managing displayed content.
Innovation Solution
A mobile terminal equipped with a grip sensor on its side surface, which, when pressed, executes functions such as select-all, release-all, and multitasking by determining the number of visual information items to display and select, allowing users to interact with visual information on the touch screen through grip inputs, while excluding non-displayed items from selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a grip sensor is added to enable new user inputs, then user interface versatility is improved, but device complexity increases
Solution Approach 1:
The grip sensor is integrated into the side surface of the terminal body to perform multiple functions including selecting visual information, executing select-all operations, releasing selections, and enabling multitasking modes. This single sensor replaces what would otherwise require multiple separate controls or touch interactions, thereby improving user interface versatility while managing device complexity.
2Productivity
If select-all function selects all visual information including non-displayed items, then operation speed is improved, but loss of information control increases
Solution Approach 1:
The select-all function is modified to operate locally based on display state. When the touch screen displays multiple pieces of visual information, the grip sensor input selects only those displayed items. When a single item is displayed, it selects that item. This localized selection approach maintains operation speed while preventing unintended selection of non-displayed items, thus preserving information control.
3Loss of information
If multiple visual information items are displayed to increase visibility, then information presentation is improved, but ease of operation deteriorates
Solution Approach 1:
The patent introduces a new dimension of interaction through the grip sensor on the side surface, perpendicular to the touch screen plane. This allows users to select and manipulate visual information without moving their hand from the gripping position, eliminating the need to reach across the screen or use complex touch gestures, thereby maintaining ease of operation even when multiple items are displayed.
4Ease of operation
If grip sensor controls all functions, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The grip sensor inputs are integrated with the existing terminal architecture, where the sensor itself is simple but the control logic leverages the terminal's existing processing capabilities. The sensor provides raw grip detection, while the terminal's existing operating system and application frameworks handle the complex selection, display, and manipulation operations, allowing ease of operation without proportionally increasing overall device complexity.

AI summary
The present disclosure relates to a mobile terminal capable of sensing an operation for gripping a terminal, including: a main body having a case for forming an exterior; a memory for storing a plurality of pieces of visual information; a touch screen arranged at the front surface of the main body and displaying at least one of the plurality of pieces of visual information; a grip sensor arranged at a lateral surface of the main body and attached to an inner surface of the case so as to sense a user input applied to the lateral surface; and a control unit for executing a select-all function, which sets at least one of the pieces of displayed visual information into an editable selection state, on the basis of the sensing of the user input through the grip sensor during the execution of an editing mode for editing the plurality of pieces of visual information, wherein the control unit does not set remaining pieces of visual information, excluding at least one piece of displayed visual information, into the selection state even if the select-all function is executed.
