Embodiment Construction

[0060] In the implementation of pattern collaborative design, the specific implementation of the method for predicting the user's attention area is as follows:

[0061] The method involves related symbol interpretation:

[0062] The context of the user's focus area: FocusContext

[0063] FocusConU k : Uk, the owner of the area of ​​interest.

[0064] FocusConU k orientation : The movement direction of the area concerned by the user Uk.

[0065] FocusConU k region : User Uk's focus area.

[0066] FocusConU k time : The time that user Uk pays attention to a certain area.

[0067] The implementation steps of this method are as follows:

[0068] 1) Rasterization of the original pattern:

[0069] Divide the two-dimensional shared workspace where the pattern is located into M*N square grid sub-areas;

[0070] 2) Initialize the area of ​​interest:

[0071] Initially determine the user's attention area and the time the user pays attention to the area;

[0072] Based on the subregion wher...

Abstract

The disclosed prediction method for focus region in cooperative design predicts the future focus region for on-line user by an expanded prediction set, which can help local user learn others' purpose, benefit to wireless mobile hand-hold system with limited screen right decide and load in advance need file for saving time.

Description

Technical field [0001] The invention relates to the technical field of real-time collaboration based on a universal environment, and in particular to a method for predicting an area of ​​interest in a pattern collaborative design under a universal environment. Background technique [0002] With the rapid development of computer technology, network and communication technology, and multimedia technology, the focus of computer applications has begun to develop from solving problems and information processing to facilitating people to communicate with each other and supporting people to work together. As a new computing model, Computer Supported Cooperative Work (CSCW) began in the 1980s, and has become a comprehensive computer technology, psychology, ergonomics, cognitive science, sociology and other disciplines. One new cross-cutting research field. [0003] The real-time collaborative design system is an important branch of the CSCW application. Its goal is to support multiple us...
