We present new alternative interfaces for zooming out on a mobile device: Bounce Back and Force Zoom. These interfaces are designed to be used with a single hand. They use a pressure-sensitive multitouch technology in which the pressure itself is used to zoom. Bounce Back senses the intensity of pressure while the user is pressing down on the display. When the user releases his or her finger, the view is bounced back to zoom out. Force Zoom also senses the intensity of pressure, and the zoom level is associated with this intensity. When the user presses down on the display, the view is scaled back according to the intensity of the pressure. We conducted a user study to investigate the efficiency and usability of our interfaces by comparing with previous pressure-sensitive zooming interface and Google Maps zooming interface as a baseline. Results showed that Bounce Back and Force Zoom was evaluated as significantly superior to that of previous research; number of operations was significantly lower than default mobile Google Maps interface and previous research.
