Dual-Base Input Device for 3D Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional input devices, such as keyboards with integrated touch pads, struggle with providing diverse and convenient input methods for 3D virtual spaces and augmented reality applications. They are limited by small size, difficulty in securing installation space, poor portability, and inability to support multi-input and interactive field changes with both hands.
Innovation Solution
An input device comprising a pair of bases with installation grooves for first and second input units. The first input unit detects palm inputs using electromagnetic and capacitive methods, while the second input unit detects finger inputs using capacitive methods. This setup allows for motion, rotation, touch, and push inputs, enabling flexible input formats and interlocking with existing electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch pad and key buttons are configured together in a conventional keyboard, then key inputting and pointer positioning functions are integrated, but the device size becomes large and portability deteriorates
Solution Approach 1:
The input device is divided into two separate bases: a first base with a first input unit for palm-based inputs and a second base with a second input unit for finger-based inputs. This segmentation allows each base to be compact while maintaining diverse input capabilities when used together.
Solution Approach 2:
Each base is designed to perform multiple input functions independently. The first base handles palm rest, palm movement, and palm rotation inputs, while the second base handles finger touch and push inputs. This multi-functionality allows the separated bases to replace the need for a large integrated keyboard-touchpad combination.
2Ease of operation
If a conventional touch pad is used for pointer positioning, then basic mouse functions are available, but multi-input and two-hand operation capability are limited
Solution Approach 1:
The input device is divided into two separate bases: a first base with a first input unit for palm-based inputs and a second base with a second input unit for finger-based inputs. This segmentation allows each base to be compact while maintaining diverse input capabilities when used together.
Solution Approach 2:
The patent combines electromagnetic induction method (for palm movement detection) and capacitive touch method (for finger touch detection) into a single input system. This merging of detection methods enables both two-hand operation and multi-input capabilities while maintaining ease of pointer positioning.
3Adaptability or versatility
If a keyboard integrated with a touch pad is used, then key input and mouse functions are available, but installation space requirement increases
Solution Approach 1:
The input device is divided into two separate bases: a first base with a first input unit for palm-based inputs and a second base with a second input unit for finger-based inputs. This segmentation allows each base to be compact while maintaining diverse input capabilities when used together.
Solution Approach 2:
The patent transitions from a two-dimensional flat keyboard surface to a three-dimensional configuration where two bases can be positioned at different locations and angles. This dimensional change allows the input device to provide comprehensive functionality without requiring a large continuous surface area.
4Productivity
If conventional input devices are used for 3D virtual space interaction, then basic 2D input is available, but diverse motion and rotation input capability is limited
Solution Approach 1:
The first input unit detects not only the position of the palm but also the movement direction and rotation angle of the palm. This dynamic detection capability allows the system to interpret complex hand gestures and translate them into diverse input commands for 3D virtual space interaction, enhancing both productivity and adaptability.
