Microsoft has introduced visual search for its new search engine, Bing.com. that will let users browse results using pictures instead of text. The company said visual search will concentrate on four main areas: travel, health, leisure and shopping. 'The whole concept is that the world of search is going to change,' Microsoft's senior vice president of online services was Yusuf Mehdi, was quoted as saying by BBC News. 'There will be a more graphic way people will search, and it will pivot how people search.'
