3D Display Cube Manipulation via Spatial Gesture Detection

Solution Overview

Problem

Existing 3D display devices and gaming systems do not provide a convenient operation method for users, as they rely on button-based interactions for navigating and interacting with three-dimensional objects, which can be time-consuming and not intuitive.

Innovation Solution

A display device and control system that includes a detecting unit to track movements in a 3D space, allowing users to select and manipulate 3D objects, such as cubes or puzzles, by positioning their fingers in the space, enabling intuitive selection and operation through spatial gestures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If button-based interaction methods are used for 3D objects, then device complexity is reduced, but ease of operation deteriorates

Engineering Contradiction:

Improveease of operationVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces mechanical button-based input systems with a camera-based detection system that tracks finger movements in 3D space. The camera detects the position and movement of fingers, and the control unit translates these movements into object manipulation commands, eliminating the need for physical buttons while improving ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a camera as an intermediary device between the user and the 3D objects. The camera captures finger movements and serves as a mediator that translates these physical gestures into digital control signals, enabling intuitive interaction without direct mechanical contact.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If button-based interaction methods are used for 3D objects, then device complexity is reduced, but productivity deteriorates

Engineering Contradiction:

ImproveproductivityVSAvoiddevice complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical button-based input systems with a camera-based detection system that tracks finger movements in 3D space. The camera detects the position and movement of fingers, and the control unit translates these movements into object manipulation commands, eliminating the need for physical buttons while improving ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces dynamic, real-time tracking of finger movements in 3D space, allowing users to interact with objects fluidly and continuously rather than through discrete button presses. This dynamic interaction method increases productivity by enabling faster and more intuitive object manipulation.

Inventive Principle:

Principle #15Dynamics

3Loss of time

If selection is made for each specific single object using operation buttons, then device complexity is reduced, but loss of time deteriorates

Engineering Contradiction:

Improveloss of timeVSAvoiddevice complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent replaces mechanical button-based input systems with a camera-based detection system that tracks finger movements in 3D space. The camera detects the position and movement of fingers, and the control unit translates these movements into object manipulation commands, eliminating the need for physical buttons while improving ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent enables users to pre-position their fingers in 3D space to select multiple objects simultaneously before executing an operation. This preliminary selection action allows users to prepare for batch operations, reducing the time required to interact with multiple objects compared to sequential button-based selection.

Inventive Principle:

Principle #10Preliminary action

AI summary

According to an aspect, a display device includes a display unit, a detecting unit, and a control unit. The display unit stereoscopically displays an aggregation of a plurality of cubes in three-dimensional space. The cubes are arranged along three directions perpendicular to one another. The detecting unit detects moves of objects in the three-dimensional space. The control unit changes a location of each of the cubes according to a detection result of the detecting unit.
