20140191941 | PORTABLE USER INPUT SYSTEM OPERABLE IN TWO MODES - A portable user interface device receives user inputs in two modes. The user interface device includes a central portion attached to two side portions. Relative rotation between the central portion and the side portions converts the user interface device between the two modes. In the first mode, the user interface device is suspended on the front of a user's torso. In the second mode, the user interface device may be placed on a substantially flat horizontal surface. | 07-10-2014 |
