1. A consultative system containing an advice and having a projection device, for helping a user to improve one's interactive ability by analyzing a particular person's behaviors in a simulation environment, said particular person being selected from a group including said user, a person different from said user, and a virtual person, said system comprising: building a plurality of virtual events for said advice, said plurality of virtual events involving interactions among two or more persons; projecting said plurality of virtual events by said projection device; capturing a response from said particular person; analyzing said response according to said advice to produce a report; and providing said report to said user, whereby said system guides said user to observe and examine said particular person's behaviors in a simulation scenario so that said user can learn effectively from both one's own behaviors and other person's behaviors and is able to apply said advice more naturally in a real life.

The system in claim 1 , said system having a recording device to record a plurality of real events, said system further comprising means for providing a plurality of variations on said plurality of real events to produce said plurality of virtual events, means for replaying said plurality of virtual events from a different direction, means for repeating a consulting session, means for tracking said plurality of virtual events, means for dispatching a corresponding advice in a plurality of formats, means for making comments, means for providing suggestions, means for providing an affirmation, wherein said report comprises items selected from a group including comments, suggestions, critical issues, responding modes, responding delays, if responding is proper, if facial expression is proper, if word used is proper, if speaking tune is proper, if gesture is proper, if said particular person focuses on a right thing, how emotion sensitive words is used, if there is any misused word, and if there is any misconduct, wherein means for providing a plurality of variations on said plurality of real events further comprise means selected from a group including means for building a different virtual environment, means for specifying a virtual person with different personality, means for changing a word by one of its synonyms, and means for changing a sentence pattern with a different one, whereby said system provides a simulation environment for said user to keep practicing so that said user can gradually enhance controllable ability on one's behavior, increase emotional sensibility, accelerate response speed, and increase observational sharpness.
