20090106820 | SYSTEM AND METHOD FOR USER AUTHENTICATION BASED ON ODOR RECOGNITION - A system for a user authentication includes an odor sensor unit for sensing an odor of a user's body to generate an odor biometric information vector, and a learning unit for performing an initial learning using the odor biometric information vector to generate a comparative odor biometric information vector. An authentication unit performs the user authentication by comparing an odor biometric information vector of the user's body to be authenticated from the odor sensor unit with the comparative biometric information vector if the user authentication is required. The authentication unit further performs an incremental learning of the comparative odor biometric information vector using the odor biometric information vector used in the authentication to create an incrementally learned odor biometric information vector. The comparative odor biometric information vector is updated with the incrementally learned odor biometric information vector. | 04-23-2009 |
20090112852 | USER MANUAL SUPPORTING METHOD AND APPARATUS USING ERROR PATTERN ANALYSIS - A user manual supporting method for use in an electronic appliance includes converting a series of operations performed by the user to operate the electronic appliance and converting the operations into a pattern of user operation sequence, and checking if an error is present in the pattern of user operation sequence to retrieve a pattern of erroneous operation sequence corresponding to the pattern of user operation sequence having the error. Thereafter, a manual content associated with the pattern of erroneous operation pattern is extracted and the extracted manual content is provided to the user. The manual content the manual content includes text and/or graphics information for notifying the user of a missing operation in the pattern of user operation sequence, or for guiding a normal operation against the pattern of erroneous operation sequence. | 04-30-2009 |
20100066866 | APPARATUS AND METHOD FOR REDUCING POPPING ARTIFACTS FOR MULTI-LEVEL LEVEL-OF-DETAIL TERRAINS - Provided are an apparatus and method for reducing the popping artifacts of level-of-detail terrain images. The apparatus includes a terrain patch constructor, a level-of-detail deciding unit, a controller, and a tapering unit. The terrain patch constructor forms terrain patches from multi-level level-of-detail patches. The level-of-detail deciding unit receives the generated terrain patches from the terrain patch constructor and decides a level-of-detail for each of the received terrain patches according to the camera distance. The controller determines whether adjacent terrain patches exist or not. The tapering unit receives terrain patches together with neighboring patches of adjacent level-of-detail from the level-of-detail deciding unit in response to the control of the controller and smoothly connects two terrain patches by applying the tapering technique. | 03-18-2010 |

The rendering server merges the reuse data with local simulation results, renders merging results, and provides a game image to a user. | 04-26-2012 |
20120129595 | APPARATUS AND METHOD FOR PROVIDING AGENT-BASED GAME SERVICE - Disclosed herein is an apparatus and method for providing an agent-based game service. The apparatus for providing an agent-based game service includes an input data management unit for collecting pieces of input data from a terminal device of at least one user. A data mining unit analyzes patterns of the pieces of input data and then generates and updates mined data according to the result of the pattern analysis. A game agent processing unit creates, using the mined data, a game agent which will replace the user and play a game instead of the user, and evolves the game agent to correspond to the updated mined data. | 05-24-2012 |
