Posture Detection for Adaptive GUI Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile information display devices struggle to adaptively display a GUI in orientations that align with user preferences when the device is held in unconventional or varying positions, limiting user convenience and usability.
Innovation Solution
The use of a combination of sensors such as acceleration, angular velocity, geomagnetic, and pressure sensors to determine the device's posture and estimate the user's relationship with the device, allowing for dynamic adjustment of the GUI orientation to ensure optimal viewing regardless of the device's orientation or holding position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the GUI is displayed based on gravity direction detection, then the display orientation is stable when held vertically, but it cannot adapt when the user rotates the device horizontally or holds it in non-standard positions
Solution Approach 1:
The patent combines multiple sensor types (acceleration sensor, angular velocity sensor, geomagnetic sensor, and pressure sensor) into an integrated posture detection system. These sensors work together to comprehensively determine device orientation and user holding position, enabling the GUI to adapt to various holding scenarios including vertical, horizontal, and non-standard positions.
Solution Approach 2:
The posture detection system is designed to handle multiple holding scenarios universally. By processing data from multiple sensors and analyzing different posture patterns, the system can determine appropriate GUI orientation for various user situations, making the device adaptable to both standard and non-standard holding positions without requiring separate detection mechanisms for each case.
2Measurement precision
If multiple sensors are used to detect device posture, then the accuracy of orientation detection is improved, but the device complexity and power consumption increase
Solution Approach 1:
The patent merges multiple sensor functions into a coordinated detection system where the acceleration sensor, angular velocity sensor, geomagnetic sensor, and pressure sensor work together. Each sensor contributes specific information about device orientation and user interaction, and their combined data is processed to achieve high-precision posture detection that would be difficult to achieve with a single sensor type.
Solution Approach 2:
The control unit acts as an intermediary that receives and processes data from multiple sensors. It integrates the information from each sensor, resolves conflicts or ambiguities in the data, and determines the most accurate representation of device posture and user intent, thereby achieving high measurement precision while managing the complexity of multiple sensors through centralized processing.
3Ease of operation
If the GUI orientation changes dynamically based on detected posture, then user convenience is improved, but the processing requirements and energy consumption increase
Solution Approach 1:
The system performs posture detection and GUI orientation adjustment periodically or event-driven rather than continuously at maximum rate. The control unit monitors sensor inputs and updates the GUI orientation when posture changes are detected, allowing the system to conserve energy during stable holding conditions while still providing responsive adaptation when the user changes their holding position.
Solution Approach 2:
The GUI orientation is dynamically adjusted based on real-time posture detection, allowing the display to adapt flexibly to user needs. The system continuously monitors sensor data and modifies the GUI orientation accordingly, creating a dynamic response that improves user convenience while the control unit manages processing efficiently by only updating when necessary based on detected posture changes.

AI summary
An information display device includes: an image display unit that displays an image according to an orientation of a display screen; a terminal posture detection unit that detects a posture of the device using an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor; and a display direction determination unit that determines whether or not the posture of the device changes, and determines the orientation of the display screen. In the case where the display screen is substantially horizontal and the posture of the device changes, the orientation of the display screen is determined so that, when the device moves by a predetermined angle or more with respect to the orientation (reference orientation) of the display screen before the determination of the posture change, a side of the device at the predetermined angle or more from the reference orientation corresponds to the top of the display screen.
