Hinged Multi-Screen Device Virtual Object Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for manipulating virtual three-dimensional objects on two-dimensional screens using external input devices are cumbersome and inconvenient for users of multi-screen mobile devices.
Innovation Solution
A mobile computing device with a housing featuring a hinge connecting two displays, equipped with sensors to detect the hinge angle and a processor that renders a two-dimensional view on one display and a three-dimensional view on the other, adjusting the perspective based on the detected hinge and gaze angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external input devices such as a mouse are used to manipulate virtual three-dimensional objects on two-dimensional display screens, then the manipulation capability is achieved, but the ease of operation deteriorates due to being cumbersome and inconvenient
Solution Approach 1:
The patent merges the manipulation interface directly into the display screens themselves, allowing users to interact with virtual three-dimensional objects by touching the display surface. This eliminates the need for separate external input devices like mice, thereby improving ease of operation while maintaining manipulation capability.
Solution Approach 2:
The patent introduces a software-based intermediary layer that translates two-dimensional touch inputs on the display screen into three-dimensional manipulation actions. This mediator enables direct finger interaction with 3D objects without requiring physical 3D input devices, resolving the contradiction between ease of operation and manipulation capability.
2Loss of information
If a single two-dimensional display is used to show virtual objects, then the device simplicity is maintained, but the information presentation quality deteriorates due to loss of three-dimensional perspective
Solution Approach 1:
The patent employs a dual-display configuration where one screen shows a two-dimensional view and the other shows a three-dimensional view of the virtual object. This dimensional differentiation across multiple displays preserves complete perspective information while maintaining a relatively simple tablet-based device structure.
Solution Approach 2:
The patent segments the information presentation across two separate displays, with each screen dedicated to showing a specific view (2D or 3D) of the virtual object. This segmentation allows simultaneous presentation of both two-dimensional and three-dimensional perspectives without requiring a single complex display, thereby reducing information loss while controlling device complexity.

AI summary
A hinged multi-screen computing device is provided that includes a housing having first and second parts coupled by a hinge, each part including a display, a sensor mounted in the housing and configured to detect a hinge angle between the first and second parts, and processor configured to render and display a three-dimensional representation of a virtual object on the first display, the three-dimensional view of the virtual object being rendered based upon the detected hinge angle.
