>>Recently, researchers at Disney came forward and said they are working on a more precise vibration technology for more "touchy" movies and games, and iPhone accessory maker Mophie will soon be releasing a new vibration pack called Mophie Pulse that uses a new type of vibrator that is thinner, lighter, 70% more energy efficient than a phone's standard vibration motor, and is capable of producing a much wider variety of "feels" than the traditional on/off "buzz." Think of it as the difference between mono and stereo but for the sense of touch instead of hearing.
With the ability to create more diverse tactile sensations, developers can make the touch-based experience more informative and more useful.
