nomenon exists generally still, improve it guides the quality, scientific training system guide research is very necessary.At this time the virtual reality technology appear in our field of vision, the virtual reality technology as the 21st century new a technology has been widely used in aviation, spaceflight, ship, railway, construction, civil, and scientific visualization, medical, education, entertainment, military, art, sports, etc.It has a multimedia information are intellectual, immersed sense, interaction, autonomy, etc.Using the virtual reality technology training system simulation and guide assessment system is a new attempt, a virtual environment is through the computer graphics consists of the three dimensional space, or make other reality of environment to a computer to generate lifelike "virtual environment", so that the user is on the vision to produce a immersion in a virtual environment feeling.In topographic map as modeling for reproduction, puts forward to establish virtual reality training system to guide this new way training mode to reform.The real with its force structure, with information query, roaming, cognitive, internal properties, teaching evaluation, etc widely intelligent virtual training system capacity, and to realize the tour guide daily training and examination of practice, the system can be applied to guide training institutions of education to students training, tour guide to guide the professionals and engaged in a professional.The application of this system will improve the efficiency of the training for the tour guide, regulating the content of the training to contribute.4) and ( 5))

Design Software and Key Codes
2. Virtual reality can be considered a "channel for communication between the designers and users.as the vr, the commission communication is a continuous process from the perspective of the concept of,, exchange of information, should always explain and both sides of the designer, who is learning the translation, construction and the design of the state of the parts of the meaning of evolution.

Experimental Task and Participants
The first study, the availability of tools to check the product, for me, a, C, e, pgfla and 3. From the scene to me.In the interface.In other words, it is this: when we define the usability testing of the virtual reality technology as an alternative to the traditional methods of evaluation, industrial products, such as virtual interface does not affect the evaluation of our own.The architecture is the virtual reality technology, equipment, products, availability in what degree of distortion degree.
In this experiment, the interaction between the results we compare the "users" product users, the availability of real "virtual" products evaluation, to the impact of the interaction between virtual interfaces.Referred to in this article is in the product, the evaluation, the current (market based on the microwave ovens and furnaces), because of the two different methods: first of all, usability testing, end users and the real product and other important interaction between users and furnace, in my model, such as the interaction between Fig. (7).In order to carry out the test (which took place in the Department of Mechanical Engineering, University of Calabria) we chose 2 samples of 10 mechanical engineering students aged 23-26 (9 samples of users A (A mates and 11 females).A and B is a consistent feature, especially in the relevant product testing, our knowledge (only five students group in the microwave oven, you can request samples) and really interface usability testing samples of the evaluation, and puts forward the existing virtual interface (b).The test results of two diametrically opposite results: on the one hand, the number of errors were found to be significantly (Table 1:6, very limited error of tasks and task 3 5 2) allows on the other hand, we have completed the task of statistical results (Table 1), but this just means that is an interface, completed the task time efficiency (ISO / DIS 9241 (11) and the efficiency of the program the number of errors), and believe, police have been actively interface usability.In fact, the trade relationship is conducive to development.But, first of all, I would like to point out that this approach can be greatly improved because of the map (8).

Experimental Task and Participants
Virtual reality system can be divided into different categories, which is dependent on certain factors, we want to emphasize particularly.Classification based on the possible level of abstraction, in a virtual environment (for example, abstract information, not the reality of the virtual environment (landscape) concrete and abstract elements), virtual reality (analog or digital acquisition), virtual environment and practical, it is difficult to tell the true colleague.Other possible factors (multi-channel perception of stimuli, are it?)Or provide quality of information.In this paper, an interactive level is provided by immersion in a virtual reality system based on classification, in particular taking into account the characteristics of the interface device.

the work experience of education, and no one in their first attempt is usually a complicated control device.Other popular virtual reality applications such as industry or medicine, users need to spend a lot of time preparing and simulating the system, the purpose is.Cultural heritage, in addition to their no professional users, does not mean that very limited time to constructive and pleasant experiences, so that they slowly learn.Ideally, users of the system can be clear, I do not want too many 5 m e, allus background and methods.This is justified if the interaction of the device is mediated by a more natural selection than.But it is usually not sufficient to fully interact with the method to effectively use these interfaces for the design.On the other hand, the system provides a better experience, but in general, lead to more powerful commitment and increased absorption of the concept and the countries of the user information, is usually very expensive, complex, installation, maintenance and management of special needs, many.So the best method is accurate target contour and target analysis, space resources.

CONCLUSION
The papers presented in the first chapter the main background of the subject's selection, the study scope, methods, and analyze relevant theories.Chapter II mostly deals with the changing process of landscape garden design ways from the visual thought to digital thought, from two-dimensional to multidimensional world, and reveals the need for virtual reality.Chapter III shows the creativity of virtual reality technology from the main concepts, features, development highlights, the current structure and application of virtual reality technology to mainstream technology.Chapter IV from theoretical level, explores virtual reality technology in the landscape garden design applications, and chapter V from the level of practice under existing conditions, describes how to construct and apply the VR in landscape architecture environment .The final paper analyzes obstacles which restrict virtual reality technology's development in the field of landscape garden design.In addition, some think of the meaning of the landscape garden design in the era of VR and prospect in the future in scenic landscape design was given by the author.
