  • Patent number: 8816965
    Abstract: Devices and methods are described for improving the efficiency of text input by requiring more pressure to select keys on a dynamic keyboard that are improbable key presses. Examples include a text-entry device which has logic for resisting error while the user enters text on a keyboard of the text-entry device. Each key has a lever mechanism which varies the force required to press the key. Keyboard logic on the text-entry device is programmed to change the force required to enter each key within the dynamic keyboard based on the prior entry. The keyboard logic assigns a prediction value to each key based on a statistical probability that the key will be entered next.

  • Patent number: 8734036
    Abstract: In a preferred form, a keyboard has a single row of eight multi-position keys with the letters arranged in a standard QWERTY keyboard configuration. The eight keys correspond to the eight fingers used when touch typing; each finger operates one key, and that key contains all the letters that the finger normally accesses when touch typing on a standard QWERTY keyboard. With this design, no finger has to move to a different key while typing. When depressed at different locations on its key face, each key either moves straight down, or down while tilting slightly about one of a plurality of axes. Three-position keys have two tilt axes and six-position keys have five tilt axes. The keys utilize contacts located on the bottom of the keys which may be conductive or nonconductive.

  • Patent number: 7538290
    Abstract: A groove-like recess, substantially V-shaped, extending vertically is formed on the outer circumference of an operation shaft, and a projection engaging the recess is provided on a guide hole, namely the inner circumference of a hollow pipe. Such makeup provides an automotive push switch that reduces an impactive force caused when the recess hits the projection within the movable range of the operation shaft, by decomposing or dispersing the force according to the inclination angle of the slope, and so does the hitting sound.

  • Patent number: 7453376
    Abstract: A system, method, and computer-readable medium having instructions for determining a key press from a current keyboard state at a current time is described. The system stores signals indicative of a last key press, a last key press time, and a last keyboard state. The system determines released keys and pressed keys on the keyboard at the current time based on comparison with the last keyboard state. The system determines a key press at the current time if the first determination determines a single key press and if either of: (a) a match exists between the determined key press and the last key pressed and if the elapsed time between the current time and the last key press time is larger than a preset bounce time; and (b) a match does not exist between the determined key press and the last key press.

  • Patent number: 7048456
    Abstract: The invention relates to a keyboard arrangement and a method for detecting an input character. In particular the invention relates to a method and arrangement for reducing the number of keys in a QWERTY-keyboard (20) or the like. One idea of the invention is to provide keys (210) with several characters and to provide alternative ways to press the key for entering a selected one of the alternative characters. The keys are preferably triangular or have three arms, and one of three characters can be selected by pressing the corresponding corner/arm of the key. The keyboard may preferably be formed of interlaced rows of keys. Linguistic disambiguation is advantageously used in addition to said mechanical disambiguation. The invention is well suited for mobile station keyboards.

  • Patent number: 6939066
    Abstract: This invention is a keyboard apparatus with front and back key functionality. The body of the apparatus is held in the hands, supported by the palms. This leaves both of the thumbs and all of the fingers free to operate the key functionality, while the apparatus is being held. Key functionality installed on the back is operated by the fingers; key functionality installed on the front is operated by the thumbs. When properly configured, the user may perform full touch-typing techniques while holding the apparatus. This configuration may reduce stress on the hands. Modifier keys are shaped, grouped and positioned so they may be operated by one thumb. Algorithms provide keyboard lock function and aid the user in locating the home row of keys needed for touch-typing.

  • Patent number: 6102594
    Abstract: Keyboard for one-handed touch typing derived from a normal Sholes keyboard, where each character-key is assigned two characters (for instance T/Y), thereby reducing the number of keys to approximately half the number of keys on a normal Sholes keyboard. The choice between the two alternative characters of a specific key is based on the mode of depression of that particular key, and hence no separate key for choise between the two alternatives is needed. The characteristics of the keyboard can either be set once and for all or can be particularly adapted to the specific user of the keyboard, such as for instance to the user's writing speed.
