I want to know the answer to the following question:
Who supervised the design and implementation of the iPod user interface?
All the background I'm provided with is that "In 2007, Apple modified the iPod interface again with the introduction of the sixth-generation iPod Classic and third-generation iPod Nano by changing the font to Helvetica and, in most cases, splitting the screen in half by displaying the menus on the left and album artwork, photos, or videos on the right (whichever was appropriate for the selected item).". Is that enough to answer the question?
Answer: no
