Mobile Terminal Grip Detection for Touch Ignoring Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals with thin bezels suffer from unintended touches on the touch screen, leading to incorrect operations and user inconvenience, especially when gripped, as they fail to recognize touch inputs in non-gripped states.
Innovation Solution
A method and mobile terminal design that detect a user's grip signal from the lateral sides to set a touch ignoring region on the screen, based on grip strength and duration, preventing unintended touches and ensuring proper functionality.

Engineering Contradiction Analysis
1Area of stationary object
If a thin bezel is used to increase display area, then the display unit size is increased, but unintended touches occur on the touch screen
Solution Approach 1:
The touch screen is segmented into a touch-recognizing region and a touch-ignoring region. The touch-ignoring region is positioned at the periphery where unintended touches occur during gripping, allowing the system to selectively ignore touches in specific areas while maintaining full functionality in the main display area.
Solution Approach 2:
Different regions of the touch screen are assigned different functional qualities: the central region maintains full touch sensitivity for user interaction, while the peripheral region is configured to ignore touches that occur during gripping, thus applying local differentiation to solve the unintended touch problem.
2Reliability
If a touch ignoring region is set at the periphery of the touch screen, then wrong operations are prevented, but touch inputs are not recognized when the device is placed on a flat surface
Solution Approach 1:
The touch-ignoring region is dynamically adjusted based on the detected grip state. When a grip is detected, the peripheral region is set to ignore touches; when no grip is detected (device placed on flat surface), the touch-ignoring region is reduced or removed, allowing full touch input recognition across the screen.
Solution Approach 2:
The system uses grip detection feedback to dynamically control the touch-ignoring region settings. The grip detection unit provides feedback about whether the device is being held, and this feedback is used to adjust the touch screen's regional sensitivity, ensuring appropriate behavior for each usage state.
3Reliability
If the touch ignoring region is fixed, then unintended touches are consistently blocked, but the device cannot adapt to different usage states
Solution Approach 1:
The touch-ignoring region transitions from a fixed configuration to a dynamic one that adapts based on real-time grip detection. The system can expand or reduce the touch-ignoring region depending on whether the device is being gripped or placed on a surface, providing consistent touch filtering when needed while maintaining adaptability to different usage scenarios.

AI summary
One or more embodiments provide a mobile terminal and a control method for setting a touch ignoring region on a touch screen of the mobile terminal. In the method, the mobile terminal detects a user's grip signal from at least one lateral side thereof. Then, based on the grip signal, the mobile terminal sets a touch ignoring region on the touch screen. In embodiments, the mobile terminal checks a gripped state thereof through a sensor and then sets the touch ignoring region. This not only prevents a wrong operation caused by an unintended touch due to a thin bezel of the mobile terminal, but also obviates any inconvenience.
