It’s just a short moment before he will leave full-time duties at Microsoft, and Bill Gates is reflecting on a longtime passion: the human-type interfaces he believes will usher computing well beyond the keyboard and mouse — everything from Tablet PCs with handwriting recognition to Surface tabletop computers that recognize objects and human touch.
