Hope the CHI reviews are not turning you down too much. 

Whether the reviews are good or not, you always have a chance to clarify the concerns and make them support your paper by writing a good rebuttal. 

I wanted to let you know that there's a collection of useful materials on writing CHI rebuttals on dgp wiki that you should check out if you haven't already: http://www.dgp.toronto.edu/dgpwiki/ResearchResources

Best,
