iPhone Nano Prototype (Standby) - I designed this prototype as an interaction study on the limits of the scroll wheel (from iPod).
This prototype has two fixed points:
2. full-surface touchscreen
Using the wheel is a form of sliding: while tactile feedback is absent on "click" operations (virtual keyboard), this is present in some ways when sliding.
So, even if probably a touch numpad will be faster (even without feedback) I tried to see if there was a way to use the wheel for this task.
