This paper introduces a novel mobile device and interaction technique for mobile computing. The proposed method uses a reversible display system and reverse operations for content browsing. The reversible display system is constructed with two displays. One is on the front surface and the other is on the back. Both displays show digital content. The user can view either display by simply reversing the screen. Our method uses the reverse directions, turn forward, turn backward, turn left or turn right, to change the displayed area. For example, when users read a map showing their current location on one display, the area to the north of the current location can be viewed by turning the display forward. When reading digital books, users can see the next page by turning the display to the right, and the previous page by turning it to the left. Our method is suitable for use in the mobile computing environment because people can browse contents with it while walking, looking around, and doing other activities.
