Jeff Han in 2006 presented through TED a breakthrough touchscreen that allowed teh user to interact with the machine. In the beginning, multi- touch interaction came about to help enhance research and it ended up being available to people to use for all purposes! Just imagine how many forms of interactive touch screens we have now ( cell phones, IPad, ITouch, etc.)!  Jeff Han states, ” I really really believe that this will change the way we interact with machines from now on. ” And from 2006 to 2010, only a mere four years, technology and innovation has really made the push to demonstrate that Han’s prediction has surely come true.
