Gesture Recognition Apparatus for Performer Specification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gesture recognition systems struggle to accurately identify the performer of a predetermined action, particularly when multiple individuals are present, as they rely on pre-registration methods and cannot distinguish between right and left hands effectively.
Innovation Solution
A gesture recognition apparatus that includes a moving image photographing part, a controller with gesture start determination, recognition area setting, shape identification, performer specification, and gesture recognition components, which detects the start action, sets a recognition area, identifies the hand as right or left, and specifies the performer based on hand position and orientation, allowing for accurate gesture recognition without pre-registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pre-registration of operators is required for gesture recognition, then operator specification accuracy is improved, but user convenience and ease of operation deteriorate
Solution Approach 1:
The system automatically detects and identifies operators in the monitoring area without requiring manual registration. The operator specification unit autonomously determines which detected person is the operator based on gesture detection, eliminating the need for users to pre-register themselves while maintaining accurate operator identification
Solution Approach 2:
The system performs preliminary detection of persons in the monitoring area and prepares operator specification data before actual gesture recognition begins. This preliminary setup enables immediate accurate identification without requiring users to go through registration procedures at the time of use
2Device complexity
If only hand raising detection is used for performer identification, then device complexity is reduced, but measurement precision of performer identification deteriorates
Solution Approach 1:
The system transitions from detecting only the vertical dimension of hand raising to analyzing the two-dimensional spatial relationship between the raised hand and face positions. By examining horizontal positioning relative to the face, the system can distinguish which person performed the gesture even when multiple people are present, significantly improving performer identification accuracy without adding complex hardware
3Measurement precision
If face authentication is used for operator determination, then operator specification accuracy is improved, but loss of time increases due to registration requirements
Solution Approach 1:
The system automatically performs operator specification by detecting persons in the monitoring area and determining the operator based on gesture detection, eliminating the need for manual face authentication and registration processes. This self-service approach maintains accurate operator identification while completely removing registration time
Solution Approach 2:
The system performs preliminary detection and tracking of persons in the monitoring area, maintaining ready-to-use identification data before gesture recognition is needed. This preliminary preparation enables immediate operator specification without requiring time-consuming authentication procedures at the moment of use

AI summary
A gesture recognition apparatus for recognizing a gesture of a hand of a user from a moving image in which action of the hand of the user is photographed is provided, the gesture recognition apparatus comprising: a face detector configured to detect a face of the user; a shape identification part configured to identify whether the hand is a right hand or a left hand; and a performer specification part configured to specify a person, who is closest to the identified hand and whose face is located on a right side of the identified hand, as a performer of the gesture when the identified hand is the right hand, and specify a person, who is closest to the identified hand and whose face is located on a left side of the identified hand, as the performer of the gesture when the identified hand is the left hand.
