Usability Research Of Design Process Of Product Based On Virtual Reality

Product's function to be complicated more and more with the development of modern technology. Meanwhile, we further require easy operation of products. On the precondition of guarantee the product's function, how to make the interactive interface learn and use easily, as well as improve customers' sense of satisfaction, namely the extent of usability, has been the new research point in the designing field.With the designing field and society promoting and attaching importance to the product usability, the research on human-centered and usability, which is regarded as the powerful weapon to break the homogeneous competition, is going to be the hotspot of research deeply. At present, it has been applied in the product designing and development of some big enterprises home and abroad.This paper includes four aspects mainly:To begin with, starting from the definition of product designing, general process, designing theory and method, sum up and settle the theory and means of product designing, then make it layered and ordered,analyse the model expression of product designing system, distill the four elements of product designing, and then discuss the necessity and significance of the innovated designing and usability research in the process of product designing.Secondly, described simply the definition of usability and usability engineering, as well as the related international standard. At the same time, differentiated and analysed the product practicability and usability, discussed the testing manner of usability. Aiming to the different character in the process of the repeated and periodical product designing, different testing means to evaluate the product usability should be taken, and the designing of mobile phone as an example.Thirdly, the real-time and apperceived interaction is the crucial point for virtual reality. So, the conceptual designing model of product under virtual reality system has no longer rested on the traditional stage just focusing on principle and sign, and the audio-visual and sight are expected. Virtual conceptual designing, namely the abbreviation of the conceptual designing on computer-aided design, based on virtual reality technology, integrates virtual reality technology with conceptual designing, applying in the product conceptual designing in virtual reality. In the process of the product designing, used the virtual conceptual designing theory to estimate the usability of product which is not yet manufactured, and researched with special attention how to adopt therelevant usability engineering methods to carry out through the usability estimation at conceptual designing stage.Finally, using the virtual conceptual designing theory to research how to carry out through the usability research of product with the product designing of computer for example.
