Mobile Device Motion Sensor Virtual Button Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile devices with touch functions, especially gaming applications, the physical presence of fingers on the touchscreen can obstruct the view and cause a poor user experience due to the need to physically interact with virtual buttons.
Innovation Solution
The integration of motion sensors embedded in the device's housing, which are connected to virtual buttons on the touchscreen via processor-established connection settings, allowing users to trigger button functions without physically touching the screen, thus maintaining a clear display and providing additional operating options through shortcut keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual buttons are displayed on the touchscreen for direct touch operation, then the device is easy to operate, but the touchscreen display area is blocked and user experience deteriorates
Solution Approach 1:
The patent introduces motion sensors as an intermediary device that detects user input gestures (such as shaking or rotating the device) and translates them into virtual button actions. This mediator allows the system to respond to user operations without requiring direct physical contact with the touchscreen, thereby preserving the display area while maintaining operational ease.
Solution Approach 2:
The patent replaces the mechanical touch interaction system with a motion-based detection system. Instead of requiring physical contact with the touchscreen surface, the system uses motion sensors to detect gestures in three-dimensional space and converts them into corresponding button press actions, substituting direct mechanical interaction with indirect motion-based control.
2Area of stationary object
If motion sensors are integrated to enable gesture-based virtual button operation, then the touchscreen display area is preserved, but the device complexity increases
Solution Approach 1:
The patent implements a universal motion recognition system that can identify multiple different gestures (shaking, rotating, tapping in air) using the same motion sensor hardware. This multi-functional approach allows a single sensor system to handle various operation types, reducing the need for multiple specialized sensors and minimizing the increase in device complexity.
Solution Approach 2:
The patent utilizes changes in motion parameters (acceleration, orientation, velocity) detected by the motion sensors to differentiate between various gestures. By monitoring and interpreting changes in these physical parameters over time, the system can distinguish between different user intentions without requiring complex hardware, thereby managing device complexity while preserving display area.

AI summary
The disclosure provides a mobile device. The mobile device includes a housing, at least one motion sensor disposed on the housing, a touchscreen disposed in the housing, and a processor electrically connected to the motion sensor and the touchscreen. The processor establishes first connection setting information between at least one virtual button in an application displayed on the touchscreen and the motion sensor, and performs a function of the virtual button in response to sensing of the motion sensor according to the first connection setting information. Therefore, the mobile device provides a better experience for a user.
