Movable Display Device with Force-Sensitive Base for 6DOF Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling images on a display device, such as computer-aided design applications, are not intuitive, precise, or convenient due to the disjoint planes of mouse movement and image manipulation, limiting the ability to control objects with six degrees of freedom and requiring frequent repositioning of the mouse.
Innovation Solution
A display system with a display device that has multiple possible poses, maintained by a physical constraint in a neutral pose until an external force is applied, uses a sensor to measure displacement and a rendering engine to render images based on the magnitude and direction of the displacement, allowing continuous image manipulation without the need for mouse repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mouse is used to control the displayed image, then the image can be manipulated, but the control becomes inconvenient and imprecise due to the disjoint planes of mouse movement and image manipulation
Solution Approach 1:
The patent merges the display device with the input device by making the display device itself movable and sensitive to touch input. The display device is positioned on a force-sensitive base that detects applied forces, combining the functions of display and input into a single integrated system, thereby eliminating the need for separate mouse and keyboard devices.
Solution Approach 2:
The display device serves multiple functions: it displays images while simultaneously detecting user input through its movable position and applied forces. This multi-functional design allows the same device to perform both output (display) and input (control) operations, simplifying the overall system architecture.
2Productivity
If the mouse is placed on a work surface to control the image, then the image can be manipulated, but the mouse must be frequently repositioned when moving the image a large distance
Solution Approach 1:
The patent transitions from two-dimensional mouse movement on a work surface to three-dimensional movement of the display device itself. The display device can be moved in any direction and distance while remaining on the work surface, eliminating the need to lift or reposition the mouse and allowing continuous image manipulation without time loss.
3Measurement precision
If six degrees of freedom are mapped to control the displayed object, then precise control is achieved, but several degrees of freedom must be locked while others are mapped to the input device
Solution Approach 1:
The display device itself becomes the input device, utilizing its own physical movement and the forces applied to it to control the displayed image. The force-sensitive base automatically detects and translates applied forces into control signals, eliminating the need for complex external input devices and their associated degree of freedom mappings.

AI summary
A display system includes a display device having multiple possible poses, including a neutral pose. A physical constraint maintains the display device in the neutral pose absent an application of an external force. A sensor measures a magnitude and direction of a displacement of the display device to a displaced pose due to the application of the external force. Then, the rendering engine renders an image on the display device according to the magnitude and direction of the displacement even while the display device remains constant in the displaced pose.
