Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing gesture control systems are inefficient and laborious when multiple functions or devices require the same gesture, as users struggle to remember and execute distinct gestures for different controls, and voice recognition is prone to errors due to noise and individual differences.

Innovation Solution

A control system that includes a gesture recognition unit, an attribute recognition unit, and a command transmitting unit, which recognizes gestures in conjunction with background target attributes such as color, shape, or patterns, allowing the same gesture to control different devices or functions by specifying the attribute of the background target.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different gestures are assigned to different functions or devices, then control functionality is provided, but users face difficulty remembering and correctly executing all gestures

Engineering Contradiction:

Improvecontrol functionalityVSAvoidgesture memorization

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

A single gesture type (e.g., pointing) is made universal by combining it with different background attributes (color, shape, pattern) to control multiple functions and devices. The gesture itself remains the same, but its meaning is differentiated through the background characteristics, allowing one gesture to serve multiple purposes without requiring users to memorize different gestures for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The background attribute (color, shape, pattern) acts as an intermediary between the gesture and the control function. Instead of directly mapping gestures to functions, the system uses background attributes as a mediating layer that connects the gesture to the appropriate device or function, reducing the cognitive load on users.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If voice is combined with gesture for control, then device selection capability is improved, but false recognition due to noise and individual differences occurs

Engineering Contradiction:

Improvedevice selection capabilityVSAvoidrecognition accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system replaces voice recognition (acoustic field) with visual attribute recognition (optical field). Instead of relying on voice commands that are prone to false recognition due to noise and individual differences, the system uses visual characteristics of the background (color, shape, pattern) which are more stable and less susceptible to environmental interference.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If a method for proposing candidate controls is implemented, then device selection becomes possible, but the control process becomes laborious and inefficient

Engineering Contradiction:

Improvedevice selection capabilityVSAvoidcontrol efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system performs preliminary action by pre-defining the relationship between background attributes and control functions. The background characteristics are analyzed in advance to determine the target device or function, eliminating the need for sequential candidate presentation and selection steps, thus improving control efficiency.

Inventive Principle:

Principle #10Preliminary action

AI summary

A control system includes: an input unit through which a signal for a gesture and a background of the gesture is input; a gesture recognition unit which recognizes the gesture on the basis of the input signal; an attribute recognition unit which recognizes an attribute of a background target of the recognized gesture on the basis of the input signal; and a command transmitting unit which generates a control command on the basis of a combination of the recognized gesture and the background target attribute and transmits the control command to a device.
