In an aspect of the present disclosure, a bidirectional interaction providing device is provided. The device includes a real-time performance unit that transmits real-time performance information through a real-time performance information session to each user terminal participating in a performance channel related to the real-time performance; an interactive reception unit that receives interaction feedback from a first user terminal through an interaction transmission session; and an interaction transmission unit that transmits the interaction feedback to a destination of the interaction feedback by referring to information on the destination.

Method and apparatus for providing bi-directional interaction for performance in metaverse space

A virtual content providing device includes: a communication circuit capable of communicating with a wearable device worn by a user; and a processor functionally connected to the communication circuit. The processor is configured to: display virtual training content on the wearable device through the communication circuit; generate training situation information and user condition information associated with the virtual training content through the wearable device; determine a intervention time point for the virtual training content based on the training situation information and the user condition information; generate virtual intervention content associated with the intervention time point; and display the virtual intervention content in synchronization with the virtual training content through the wearable device.

Wearable device, virtual content providing device, and virtual content providing method

Provided are an apparatus and method for experiencing an augmented reality (AR)-based screen sports match which enable even a child, an elderly person, and a person with a disability to easily and safely experience a ball sports match, such as tennis, badminton, or squash, as a screen sports match without using a wearable marker or sensor, a wearable display, an actual ball, and an actual tool.

Apparatus and method for experiencing augmented reality-based screen sports match

A similarity calculating method and apparatus are disclosed. A similarity calculating method according to an exemplary embodiment of the present invention includes extracting similarity calculating data, which is determined in advance, by receiving a communication activity record for every user; modeling a communication activity pattern for every user and common information between the users based on the extracted similarity calculating data; and calculating a similarity between users using the modeled communication activity pattern for every user and common information. The modeling includes: modeling the communication activity pattern by calculating a value of a static feature from the similarity calculating data, and modeling the common information by calculating a value of a dynamic feature from the similarity calculating data.

Similarity calculating method and apparatus

Proposed is a data visualizing apparatus for visualizing data as effectual information using a correlation between forensic data collected from various sources. The proposed data visualizing apparatus may visualize, as effectual information, single-source single-data, single-source multi-data, and multi-source multi-data.

Apparatus and method for visualizing data

Provided is a forensic index method by distributed processing, including: generating data to be divided by dividing data to be indexed according to predetermined division setting for distributed processing; allocating the generated data to be divided to a plurality of data processing units according to the predetermined division setting, extracting an index by filtering the allocated data to be divided in the plurality of data processing units, and generating divided index data including the extracted index; and generating an index database by merging the generated divided index data.

Forensic index method and apparatus by distributed processing

A system and method for data analysis and digital forensics is provided. The system for data analysis and digital forensics may include: an online data forensic server for collecting and analyzing usage history information from an object device, which is subject to data collection, downloading and collecting data on the Internet based on the usage history information, requesting issuance of a timestamp token for the collected data, and receiving the issued timestamp token; a timestamp token issuing server for issuing the timestamp token for the collected data in response to the request for issuance of the timestamp token and proving the issued timestamp token to the online data forensic server; and a storage device for storing the collected data.

Method for data analysis and digital forensics and system using the same

An iris recognition method is provided. In the iris recognition method, binary image data is obtained by receiving eye image data and filtering the received eye image data using a predetermined threshold value. Then, candidate center search regions are searched for finding a pupil center using profile information of rows and columns of the binarized image. a pupil boundary and a center point are detected by performing a mask operation using 8 pupil boundary mask templates for each of concentric circles formed of pointes in the searched candidate center search regions as candidate pupil centers and different radiuses. An iris boundary region is detected by performing a masking operation using 6 iris boundary mask templates corresponding to 6 locations for concentric circles formed of the pupil center as an origin and different radiuses.

Iris recognition method and apparatus thereof

A method of iris recognition using a cumulative-sum-based change point analysis and an apparatus using the same are disclosed. The method includes: transforming an iris image to a polar coordinated image having n&#xd7;m pixel size and dividing the polar coordinated image into at least one cell; grouping the divided iris images into at least one of first groups having a predetermined number of cells, and at least one of second groups each having more cells than the first group has; performing a cumulative-sum-based change point analysis using a predetermined characteristic pattern value of each cell as a representative value; and generating a pattern vector by assigning a predetermined value to a cell having the change point and assigning a different value to other cells.
