The history of the design and manufacture of the TiVo remote control.
Like any remote, the designers were adamant about keeping the remote's button layout as simple as possible. But with the DVR's numerous features, the designers needed to create lots of extra buttons. To keep things straight, each button needed to have a distinctive feel, giving the ability to control the remote without even looking at it, which Newby described as a "key Braille-ability" surprisingly helped by the "blank finger parking spots between keys" that were equally important.
