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.
Comfortable fit for the fingers of the right hand makes key input easy
Making the calculator fit the person, not the person fit the calculator
Calculator is used with right hand angled
Keystroke direction stays vertical
Sloping the keypad surface 3° ensures an comfortable fit with the fingers of the right hand. Arranging the keys themselves in an un-sloped step configuration keeps the keystroke direction vertical. This all-new structure makes key input with a natural hand position easy.
Person-centered, friendly design
