Study on capturing of user requirements based on persona

In order to make the product design can further meet the real needs of users, obtaining the user needs accurately becomes very critical in the design and development stage. A new method, which could get user demand of products based on the persona, is presented. It determines the typical user through the scene segmentation, extracts user personas model by combining 5W2 H method, refines the character model of user demand for clustering by KJ method, and then gets a typical user demand index system. It uses the improved subjective weighting method to determine the parameters of weight, weight of each scheme and compares the final user needs. And a wireless mobile terminal product form design is taken as an example to illustrate it.
