Mobile Terminal Hot Key Execution via Combined Touch and Motion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with limited touch screen sizes require intuitive user interfaces that can execute various functions through simple manipulations, as existing technologies do not effectively allow users to input commands using both touch and motion.
Innovation Solution
An apparatus and method that utilize a combination of touch detection and motion detection units, along with a controller, to perform hot key functions on a mobile terminal by detecting user input and motion, enabling functions like data sorting, menu selection, folder management, and communication through directional movements on the touch screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the touch screen size is limited, then the device portability is improved, but the user interface complexity increases requiring complicated manipulations
Solution Approach 1:
The patent introduces motion detection as a new dimension of input beyond the two-dimensional touch screen. By detecting device motion in three-dimensional space (using accelerometer and gyro sensor data), the system enables commands to be issued through physical movement patterns, effectively adding a spatial dimension to the user interface that bypasses screen size limitations
Solution Approach 2:
The patent segments the user interface into multiple input modalities: touch input for basic selection and motion input for command execution. This segmentation allows the touch screen to remain simple for display purposes while motion detection handles complex command input, resolving the contradiction between limited screen real estate and interface capability
2Ease of operation
If motion detection is added to enable intuitive commands, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent makes existing sensors serve multiple functions: the accelerometer and gyro sensors, originally designed for basic motion tracking and orientation, are repurposed to detect specific motion patterns for command input. This multi-functionality approach enables intuitive command execution without adding dedicated hardware, thus improving ease of operation while minimizing the increase in device complexity
Solution Approach 2:
The system uses the device's own inherent motion characteristics and existing sensor capabilities to enable command input, rather than requiring external or specialized hardware. The motion detection system leverages the natural movement of the device in the user's hand, turning the device's own physical properties into a resource for enhanced user interaction

AI summary
An apparatus and a method for executing a hot key function of a mobile terminal provide that, if a motion of the mobile terminal is detected and a touch of a user is detected, a specific hot key function is executed, so that the user may input commands according to the touch of the user and the motion of the mobile terminal.
