Easy key input with the right hand
How could we design a calculator that would make key input with three to five fingers of the right hand easier than ever before? This was the question that guided our research into exactly what happens to the hand and fingers when people use a calculator.
Working with a specialized institute, we devoted ourselves to re-envisioning a calculator that was, in fact, already highly optimized. After plenty of trial and error, we settled upon a totally new calculator shape that defies all convention.
