Abstract: Visual search user interfaces are intuitive and with strong ability of interaction,which have been widely adopted in many search engines.In this paper,applications of visual user interface in the search system are summarized.We respectively investigate how to visualize query formulations and how to organize search results in visualization.And we investigate both classification based and feature based visualization of query formulation,and then describe methods of how to organize search results in visualization.At last,this paper concludes that natural interaction,non-text data,data scale and socialization will have a huge impact on visual search user interface,and those relative technologies are worth study in further.
