3D INFORMATION. “Today, even with our high-end mobile devices, high-definition displays, and digital surround sound, the experience delivered is still something outside ourselves, only as close to us as our eyes and ears. Digital information remains two dimensional: something we look at, listen to, and read about. Haptic touch is the missing piece, the sensory element that will transform information into experience.”
