20110246871 | OPTIMIZED READING EXPERIENCE ON CLAMSHELL COMPUTER - The provision of an optimized arrangement for reading tasks at a clamshell or laptop computer, particularly to facilitate reading in portrait mode. Further contemplated herein are arrangements for readily switching between a reading (portrait) operating mode and a “normal” (landscape) mode. Such changes could be brought about via essentially any suitable arrangement, such as via an accelerometer which acts automatically, or a hotkey which is activated manually. Additionally contemplated herein is the use of mouse keys for alternative purposes specific to switching between the reading/portrait modes, such as utilizing left and right mouse buttons for page up and page down controls for reading (in portrait mode). A mouse pad (touchpad) can also be employed for alternative purposes in reading/portrait mode, such as the use of horizontal mouse pad scrolling for vertical document scrolling in reading/portrait mode. | 10-06-2011 |

20130132885 | SYSTEMS AND METHODS FOR USING TOUCH INPUT TO MOVE OBJECTS TO AN EXTERNAL DISPLAY AND INTERACT WITH OBJECTS ON AN EXTERNAL DISPLAY - Systems and methods are disclosed herein that generally involve allowing movement of windows or other user interface objects back and forth between a touch screen display and a non-touch display using only touch inputs. In one embodiment, a “send” touch gesture performed on a window displayed on the touch screen display causes automatic movement of the window to the non-touch display. A tab corresponding to the moved window is then displayed on the touch screen display. The tab can be used to interact with the window using touch inputs, even though the window has been moved to a non-touch display. For example, a “retrieve” touch gesture can be performed on the tab to move the window back to the touch screen display, or a “select” touch gesture can be performed on the tab to bring the moved window to the front and give the moved window focus. | 05-23-2013 |
