Hand Skin Surface Print Identification via Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for identifying users do not efficiently utilize computational power and are not suited for use in television systems, lacking methods for user identification through objects held in the hand without excessive processing requirements.
Innovation Solution
A system and method that captures an image of the skin surface print between the metacarpophalangeal and distal interphalangeal joints of a user's hand, processes this image to construct a signature, and searches a database for a match, using a remote processing device with an image capture device and transmitter, optionally employing lossy conversion processes to achieve efficient identification with up to 80% accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If biometric identification methods are used to identify a user, then user identification accuracy is improved, but computational power requirements and device complexity increase excessively
Solution Approach 1:
The patent extracts only the essential features needed for identification from the complete hand image. Instead of processing the entire hand or using complex biometric algorithms, the system captures an image of the hand holding the remote and extracts key geometric features (finger positions, hand orientation, grasp pattern) to create a simplified signature for database matching, thereby reducing computational requirements while maintaining identification accuracy
Solution Approach 2:
The patent creates a simplified copy or representation of the hand image in the form of a signature. This signature is a condensed version containing only the essential identification features, which can be quickly compared against stored signatures in the database without requiring complex computational processing of the original high-resolution image
2Measurement precision
If traditional biometric systems are implemented in television systems, then user identification capability is improved, but ease of operation and system integration deteriorate
Solution Approach 1:
The patent makes the remote control device multi-functional by integrating both the identification function and the television control function into a single device. The remote control not only controls the television but also serves as the identification medium, eliminating the need for separate biometric sensors and simplifying system integration
Solution Approach 2:
The identification system is self-service in that the user simply needs to hold the remote control in their hand for the image to be captured. The system automatically processes the image, extracts the signature, and performs database matching without requiring the user to actively participate in the identification process or understand the technical details

AI summary
A system and method for identifying a user through an object held by a hand of the user, according to an image of the skin surface print of a portion of the hand of the user, which is optionally the skin surface print of at least a portion of the hand between the metacarpophalangeal joint and a distal interphalangeal joint of one or more fingers. Optionally, the image only includes the skin surface print of at least a portion of the hand between the metacarpophalangeal joint and a distal interphalangeal joint of one or more fingers. The method for identifying the user may also optionally only use selected portions of this image as described herein. Related apparatus and methods are also described.
