The references are based on working for touch applications, talking to users, and a reference which was spoken of on this forum some time back.
http://www.sapdesignguild.org/resources/TSDesignGL/Index.htm Also, Preeti spoke of something similar to HP Touch. I am sure 1 cm works for an iPhone, but would it always work for all other products? Example, I worked on a product for oil drillers, who wore gloves, and we wanted to have a 'big enough' target size. So I am sure there is an accepted range of value, 1 cm may be the minimum most requirement, as suggested by you. But only a starting point. Sincerely, - Kunal.
