Abstract: To provide the effective assisting means for product's design assessment,four interface layout elements that influenced user perception were analyzed and twelve metrics of interface layout characteristics were proposed by around  the user perceptual prediction of product information interface.The reliability of the interface layout metrics system was verified,and the result showed that the layout metrics system met the basic set of four potential factors,but the multiple correlation was existed between the layout metrics and subjective evaluation which could improve the initial perceptual mapping model.The different prediction models were created by using two types of applied neural network and linear regression methods.Through contrasting the predicted deviation of test samples,the result showed that linear regression prediction model had higher degree of data fitting and the function relationship of perceptual prediction model AM=g{f(M)} was deducted.Theoretical basis of interface layout design and program evaluation were also provided.

Key words: interface layout, perceptual prediction, confirmatory factor analysis, neural network, linear regression, product design
