Dual-Side Touch Display Mode Switching via Grip and Rotation Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices with dual displays on both sides lack the ability to dynamically adjust content presentation based on user intention and location, limiting their functionality and user experience.
Innovation Solution
A display device equipped with a sensor unit to detect the gripped state and rotating state of the device, and a controller to change the display mode of the second touch display area based on the detected information, allowing it to switch between full screen, input, and predetermined modes depending on the rotation angle and maintained gripped state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device uses fixed display modes for front and rear displays, then the device structure is simple, but the adaptability to user intentions and location is poor
Solution Approach 1:
The display device dynamically adjusts display modes based on real-time detection of user grip state and device rotation angle. The controller automatically switches between different display modes (e.g., first display mode for front display, second display mode for rear display) according to the detected orientation and user interaction, making the system adaptive without requiring complex manual configuration.
Solution Approach 2:
The display device uses sensors to automatically detect user grip state and rotation angle, then the controller autonomously determines and switches display modes without requiring user intervention. The system serves itself by interpreting sensor data to automatically adjust content presentation, reducing the need for complex user input mechanisms.
2Quantity of substance
If the display device only shows 2 contents via front and rear displays, then the device structure is simple, but the quantity of displayable contents is limited
Solution Approach 1:
The display device enables both front and rear displays to present the same content or different content based on user intention and location. The system can display multiple contents simultaneously on different displays or switch content based on rotation angle, allowing a single device to serve multiple display functions and increase the quantity of displayable contents without proportionally increasing complexity.
Solution Approach 2:
The content selection and display mode are dynamically adjusted based on real-time detection of device rotation angle and user grip state. The controller automatically selects which content to display on which display device based on current orientation, enabling the system to present multiple contents adaptively without requiring complex manual content management.
3Ease of operation
If the display device does not detect user grip state changes during rotation, then the control system is simple, but the ease of operation is reduced
Solution Approach 1:
The display device continuously monitors user grip state and device rotation angle through sensors, providing real-time feedback to the controller. Based on this feedback, the controller automatically adjusts display modes and content selection, making operation easier by eliminating the need for manual buttons or switches while maintaining simple user interaction.
Solution Approach 2:
The system uses sensors to automatically detect changes in user grip state and rotation angle, then autonomously switches display modes and content without requiring user input. This self-service approach improves ease of operation by automatically interpreting user intentions from sensor data while keeping the control mechanism relatively simple.
Data Source
AI summary
A display device and a method of controlling therefor are disclosed. The display device includes a display configured to include a first touch display area which is arranged to display content toward a first direction and a second touch display area which is arranged to display content toward a second direction corresponding to an opposite direction of the first direction, a sensor unit configured to detect a gripped state of the user and a rotating state of the display device and when it is determined that the second touch display area is facing the first direction at which the user is positioned based on the gripped state and the rotating state, a controller configured to change a display mode within an identical content which is outputted in the second touch display area.
