Patent number: 8508481Abstract: A method, system, and medium are provided for improving the accuracy of keystroke detection by determining what finger position a person is using to type. The finger, or fingers, used to contact the keys may define a finger position. Once the finger position is detected, hot spots for individual keys may be positioned according to a profile associated with the finger position. The hot spot is the portion of the touch screen that needs to be contacted in order to register a keystroke for the associated key. Each key has its own hot spot. The hot spot for a key may change without the display of the key on the touch-screen keyboard changing.Type: GrantFiled: July 1, 2010Date of Patent: August 13, 2013Assignee: Sprint Communications Company L.P.Inventor: Shane Jeremy Landry

Patent number: 8466861Abstract: A liquid crystal display device displays an image by stacking a plurality of liquid crystal panels, and by controlling a light transmittance with voltage application to liquid crystal of each panel, wherein during execution of voltage application to the liquid crystal of one of the panels, a voltage to the liquid crystal of the other panel serves as a non-display voltage. No image is displayed simultaneously on the two or more stacked liquid crystal panels. In the liquid crystal panel to which no voltage is applied and on which no image is displayed, the longitudinal axial direction of liquid crystal molecules coincides with the polarizing axial direction of polarizers, or is orthogonal to the polarizing axial direction; therefore, no influence is exerted on the overall double refraction, and the overall voltage-transmitted light intensity characteristic corresponds to the sum of the voltage-transmitted light intensity characteristics of the respective panels.Type: GrantFiled: April 1, 2008Date of Patent: June 18, 2013Assignee: Fujitsu LimitedInventors: Toshiaki Yoshihara, Tetsuya Makino, Shinji Tadaki, Hironori Shiroto, Yoshinori Kiyota, Keiichi Betsui

Patent number: 8373655Abstract: Disclosed herein are methods and systems for providing a user interface (UI) having a selector controllable by a physical input device. The response of the selector is adaptively adjusted to facilitate executing desired operations within the UI. A response factor defines how far the selector moves for a given movement of the physical input device. The response factor is increased so the selector can be moved a large distance, but is dynamically decreased to provide fine-tuned control of the selector for selecting densely grouped screen elements. Screen elements can be endowed with gravity, making them easy to select, or with anti-gravity, making them more difficult to select. The disclosure methods also provide tactile feedback such as vibration or braking of the physical input device to assist a user in executing desired operations.Type: GrantFiled: January 5, 2007Date of Patent: February 12, 2013Assignee: Apple Inc.Inventors: Howard A.
