User Experience Test Evaluation Technology And Application On Ordour

In twenty-first Century,“The user is supreme” and experience economic rapid developed.The design and development of new products,especially the design and development of new products for automotive industry must be taking into account the users' comfortable degree and users' satisfaction and they are the key elements,this requires the designers to carry on the user experience testing and evaluation to design and develop the product.And the results of the evaluation of the user experience will provide critical guidance for the design and development of new products.At present,the research on the user experience testing at home and abroad mostly stay in the visual,auditory and tactile levels,the sense of smell level of the user experience test can be counted on one's fingers.Therefore,the research in this direction will no doubt be a new way of thinking and will provide a great help to the development of new automobile products especially on the olfactory interaction design in the future.In this paper,we developed a smell experience instrument principle prototype on olfactory experience,and carry on an experiment about automobile inner order by it.This paper proposes a user experience testing evaluation method which based on facial expressions and t psychological scale.The user preference model between the different emotional intensity values and user preference is established by BP neural network algorithm.And it will be applied to the study of automotive interior order.
