  • Patent number: 7853876
    Abstract: A method to imitate lifelike images for computer deformed objects includes the following steps, selecting a number of significant points on an object, categorizing the significant points into measurable points and specific points, defining a relationship between the measurable points and the specific points with a statistical regression model, creating a table of weighted values for the specific points and animating an object based on the weighted value table. The present invention uses the measured displacement of a number of measurable points to calculate expected positions of the specific points to reduce processing time and create real time images. The method uses a statistical analysis method to decrease access time to a database, save storage space of the database and create lifelike, real-time and animated images in accordance with the object as the object changed its surface.

  • Patent number: 7756950
    Abstract: A system and method for providing mobile information, a server and a portable device therein are provided. The server comprises an intelligent download manager and the portable device comprises a file browse manager. The intelligent download manager determines a downloaded file update rule and a file browse rule according to any combination of a document attribute, a browse record, and a document preference. The files to be downloaded to the portable device can be determined automatically according to the downloaded file update rule. The file browse manager provides an intelligent browse mode related to the browse sequence of the downloaded files according to the file browse rule. Therefore, information really interesting to the user can be stored in the limited space by the present invention and the user can access the information quickly and efficiently.

  • Publication number: 20100120002
    Abstract: Disclosed is a system and method for conversation practice in simulated situations. The system comprises situational conversation teaching material, an audio processing module and a conversation processing module. The teaching material consists of multi-flow conversation paths and conversational sentences with a plurality of replaceable vocabulary items. According to different contents of the situational conversation teaching material and biased data of the teaching material, the audio processing module dynamically adjusts speech recognition model and recognizes the inputted audio signal of the learners to determine the information on the recognition results. The conversation processing module determines the information in response to the learners, based on the information on the recognition results, the situational conversation teaching material and biased data of the teaching material.

  • Patent number: 6693632
    Abstract: A method of area partition in virtual environment is disclosed. It can be used to divide 3D (Three Dimensions) virtual environment into several subareas. The invention interposes neighboring subareas so that the subareas in the same plane and the subareas in adjacent planes mix with one another. Both the number of subareas adjacent to each subarea and the number of subareas an object crosses can be decreased, thus lowering the load in operations.
