Motion-Based Display Control for Mobile Terminal Misoperation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication terminals often experience inadvertent misoperations and increased power consumption due to user contact with keys or touch-sensors during calls, leading to issues like screen lighting and hanging up.
Innovation Solution
An information processing device equipped with a motion detecting unit, such as a 3-axis acceleration sensor or gyroscope, that generates motion-related data to control the enable/disable state of the display and input units, preventing accidental activations when the device is in use near the ear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display unit and input unit are kept enabled during calls, then user operations are responsive, but inadvertent misoperations occur when the user's ear contacts the device
Solution Approach 1:
The patent applies dynamics by making the enable/disable state of the display unit and input unit changeable based on detected motion. The system transitions between different operational states (enabled/disabled) according to motion detection results, allowing the interface to adapt dynamically between responsiveness and misoperation prevention based on actual usage conditions
2Ease of operation
If the display unit and input unit remain enabled during calls, then the device is ready for immediate interaction, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the power state of the display unit and input unit based on motion detection. When no significant motion is detected (indicating the device is held stationary near the ear), the units are disabled to save power. When motion is detected (indicating the device is being moved away from the ear), the units are enabled to prepare for interaction, thus optimizing power consumption based on actual usage needs
3Reliability
If motion detection is used to control enable/disable of display and input units, then inadvertent operations are prevented, but device complexity increases
Solution Approach 1:
The patent introduces a motion detecting unit as an intermediary component that provides motion-related data to the processing unit. This intermediary sensor enables the system to distinguish between intentional user actions and inadvertent contact, allowing reliable control of the display and input units without requiring complex control logic or multiple sensors
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents screen lighting and misoperations during calls, enhancing user experience and reducing power consumption by disabling the display and input units unless significant motion is detected, indicating the device is being removed from the ear.
Implementation Method 1
a motion detecting unit, configured to detect motion of the information processing device, and to generate motion-related data
