3D Input Device for Intuitive Virtual Object Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices are inadequate for controlling objects in virtual 3D spaces, as they are designed for 2D interfaces, making it difficult for users unfamiliar with technology, such as children or elderly individuals, to interact with 3D environments like 3D games or the internet.
Innovation Solution
An input device equipped with first and second contact sensors to detect movements along 3D spatial axes, generating contact information that is analyzed to create input signals to control objects on a display device, allowing for intuitive manipulation of objects in virtual 3D spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing input devices are used, then they are suitable for 2D interfaces and command line interfaces, but they are inappropriate for controlling objects in virtual 3D space
Solution Approach 1:
The patent transitions from 2D input interface to 3D input interface by adding a vertical coordinate axis sensor. The input device now detects contacts in three-dimensional space (X, Y, and Z axes), enabling users to control objects in virtual 3D environments through intuitive spatial gestures rather than traditional 2D keyboard or mouse operations.
2Ease of operation
If traditional input devices are used, then they provide standard 2D input functionality, but they create difficulty for users unfamiliar with technology such as children and elderly individuals
Solution Approach 1:
The input device enables self-service operation by allowing users to directly control objects through intuitive contact gestures in 3D space. The system automatically interprets spatial contacts and generates appropriate control signals without requiring users to learn complex commands or interfaces, making it accessible to children and elderly individuals.
3Adaptability or versatility
If 3D contact sensors are added to enable 6 degrees of freedom control, then control capability in virtual 3D space is improved, but device complexity increases
Solution Approach 1:
The input device is segmented into multiple contact sensors, each responsible for detecting contacts along specific coordinate axes. The first contact sensor detects contacts along planar coordinate axes (X and Y), while the second contact sensor detects contacts along the vertical coordinate axis (Z). This segmentation allows the complex 3D control function to be divided into simpler, manageable sensor components.

AI summary
Provided is an input device that may sense a first contact occurring along a planar coordinate axis among three-dimensional (3D) spatial coordinate axes to generate first contact information, to sense a second contact occurring along a vertical coordinate axis among the 3D spatial coordinate axes to generate second contact information, to analyze contact information including at least one of the first contact information and the second contact information to generate an input signal to control a predetermined display device, and to transmit the generated input signal to the display device. The display device may control an object that is displayed on the display device, based on the input signal.
