| With the continuous development of the contemporary society, the people's living levels have been taken a rapid increased. People's aesthetical appreciation and enjoyment of product have been taken great changed. These incarnate that customer's seeking novelty and larruping demand for products. This demand impacts customer's current purchasing action and future purchasing trend, and this trend influences the emphasis of industrial design deeply, and leads to the content and form are changing greatly.After rapid development for 30 years, industrial design in China has been broken through both in academics and practices, and is closing to the highest level of the word. But owing to falling behind the component technologies of industrial design, such as IT, material technology, manufacture technology, electronic technology and so on, these lead to industrial design level of our country falls behind the advanced countries. In order to make up this gap in short order, we have to break through in theory first, so as to supervise our design through the new theory.Taste, touch, vision, hearing and smell are the five senses of people, in order to make the design meet people's favorite demand. We have to consider these five aspects of people's senses how to meet and even exceed the users' demand for products. Industrial product is always realizing some functions, during these processes product itself or one part displacement and condition will be changed, the changes include shift change, velocity change, moving way change, color change, light change ,sound change and so on. These changes act on customer's vision, hearing and touch, and make user produce different psychological feeling, this feeling directly influence on the reliability, accuracy, safety, comfort and advanced technology of the product.This thesis considers that the displacement of product and product parts, and the condition changes as action, and analyzes action with ergonomics, psychics, mechanical engineering, aesthetics, and studies the emphasis function and significance of action in product design. Author got user's psychological impression by analyzing the lights, sounds, colors, movement machines and movement ways that combining with user's vision and hearing. The author built up the form beauty's principles of action by analyzing the action factors with aesthetics and design aesthetics. The author further demonstrated the value and significance of action by analyzing the action aesthetics and its aesthetic value. Through above analyses author built up the action aesthetics, and discussed principles and ways to improve the aesthetic value of action. Finally, the author demonstrated the feasibility of action aesthetics by a car audio's successful design which under the instruction of action aesthetics.The study and practice of product action aesthetics are help to broaden industrial designer's thought actively, meanwhile, enrich the academic system of industrial design and enhance the design level significantly. |
