Dual Touch Interface 3D Virtual Object Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices with single touch interfaces can only perform 2-dimensional manipulation of virtual objects, limiting user interaction and intuitive control.
Innovation Solution
Implementing two touch interfaces, one on the front and one on the rear of a device, which can detect touch inputs and generate a 3-dimensional segment for controlling virtual objects using direct touch or pre-touch sensors, allowing for 3-dimensional manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single touch interface is used, then the device structure remains simple, but the manipulation capability is limited to 2-dimensions
Solution Approach 1:
The patent applies dimensionality change by adding a second touch interface on the rear of the device, transforming the manipulation capability from 2-dimensional to 3-dimensional. The front touch interface provides X-Y plane control while the rear touch interface adds the Z-axis dimension, enabling intuitive 3-D manipulation of virtual objects without significantly increasing overall device complexity.
2Adaptability or versatility
If two touch interfaces are implemented, then 3-dimensional manipulation is enabled, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the touch control functionality into two separate interfaces - a front touch interface and a rear touch interface. Each interface independently detects touch inputs and processes them separately, with the front interface handling primary controls and the rear interface providing additional dimensional control, thereby managing complexity through functional division.
Solution Approach 2:
Both the front and rear touch interfaces utilize the same touch detection technology and processing mechanisms, making each interface universal in its capability while serving different functional purposes. The rear touch interface mirrors the front interface's functionality but oriented differently in space, allowing the same hardware design to be replicated for multi-functional 3-D control.

AI summary
A virtual object can be controlled using one or more touch interfaces. A location for a first touch input can be determined on a first touch interface. A location for a second touch input can be determined on a second touch interface. A three-dimensional segment can be generated using the location of the first touch input, the location of the second touch input, and a pre-determined spatial relationship between the first touch interface and the second touch interface. The virtual object can be manipulated using the three-dimensional segment in c) as a control input. The manipulated virtual object can be displayed on a display.
