  • Patent number: 9489086
    Abstract: Typing on touchscreens is improved by dynamically and automatically positioning the desired home-row keys of an onscreen keyboard below the user's fingers while their fingers are hovering above the surface, thus reducing the need for the user to look at the onscreen keyboard while typing. The location of each of the user's fingers while hovering and/or resting is monitored. Correlation between the hover sensor data and touch sensor data increases the confidence level by which the system can determine which of the user's fingers were used to select a key. By determining which finger was used to make the selection, the system accurately disambiguates which letter the user intended to type.

  • Patent number: 6473069
    Abstract: A method and apparatus for providing tactile feedback to a user moving his/her finger across the touch-sensitive surface of a touchpad or tablet. Different regions of the touch-sensitive surface are differentiated from each other by providing a different human perceptible textural surfaces within the regions. A different texture provides immediate tactile feedback to the user through the finger making contact with the touchpad. Increased functionality is important because it solves problems which are inherent to the small touchpad surfaces used as computer input devices. Particularly, it is a problem to drag an object from one side of a display to another without repeatedly raising a finger to repeat the dragging motion because of the limited surface area of the touchpad surface. Providing increased functionality such as a drag extend function solves the movement problem.

  • Patent number: 6222528
    Abstract: A method and apparatus for providing accelerated X and Y axis position determination of a probe relative to a touchpad surface by enabling determination of the X and Y axis coordinates independent of each other. The apparatus of the present invention enables simplification of the electronics of the touchpad because fewer sense lines are required to achieve position resolution which is finer than the electrode pitch. Position determination is further accelerated because fewer position measurements are then required to compensate for such problems as probe symmetry duplication.

  • Patent number: 5914708
    Abstract: A system comprising a conductive stylus used in conjunction with a capacitance sensitive touch pad, said system providing at least two different signals to an associated computer system. The stylus is a pen-like device having an actuable switch which when actuated substantially increases the capacitive disturbance caused by the conductive stylus on the touch pad. Before actuation, the stylus creates a capacitive disturbance sufficient for circuitry in the touch pad to measure as crossing a first predefined capacitive disturbance threshold when the foam covered conductive stylus tip is brought in contact with the surface of the touch pad. When the switch is actuated, the capacitive disturbance measured by the touch pad increases sufficient to cross a second predefined capacitive disturbance threshold. An associated computer program for drawing on a computer display places a cursor on the display when the first threshold is crossed.

  • Patent number: 5767457
    Abstract: A method and apparatus for developing an audible feedback in the form of a response signal to a tapping motion, a gesture or a series of taps or gestures on an electronic touch-sensitive computer input device which uses an electronic switch having no mechanical switch component. In particular, the present invention is beneficial for a touch-sensitive input device a touch-pad or stylus and tablet because it is difficult for the user to know whether a tapping motion is perceived by the device's sensing circuitry. The method is less than perfectly reliable because it is often difficult for the user to know whether sufficient pressure was applied to the touch-sensitive surface of the device, or whether contact was made for a sufficient amount of time. Consequently, the user must wait to see if the computer responds in the desired manner. If not, the user must repeat the motion.

  • Patent number: 5757368
    Abstract: A method and system for extending the distance which a user can drag a cursor across a computer display device when using a touch sensitive pointing device as a relative cursor locating device. When such relative cursor locating devices are used the small perimeter size of the position sensing surface makes it inconvenient to carry out drag required functions. A border within the outer perimeter of the position sensing surface is defined and when a pointing object enters the border on the position sensing surface it is detected. It is then determined if the drag function is engaged for the cursor when the pointing object enters the border. If the drag function is engaged, the present invention holds the cursor at the location on the computer display while the user moves the pointing object to a new position on the position sensing surface from which position the user continues the dragging function to a desired end location on the computer display.

  • Patent number: 5565658
    Abstract: Apparatus and method for a capacitance-based proximity sensor with interference rejection. A pair of electrode arrays establish a capacitance on a touch detection pad, the capacitance varying with movement of a conductive object near the pad. The capacitance variations are measured synchronously with a reference frequency signal to thus provide a measure of the position of the object. Electrical interference is rejected by producing a reference frequency signal which is not coherent with the interference.

  • Patent number: 4563739
    Abstract: A computer based system is used for taking inventory and obtaining inventory reports on numerous products which are dispensed in full containers or in quantities from partially filled containers. Each container includes a unique code identifying the product therein. A code sensor such as a bar code reading wand supplies signals to the computer identifying the product. A weighing device supplies signals to the computer indicative of the weight of partially filled containers. Inventory information is obtained by sensing the code of full containers and entering the number of full containers present at a dispensing station or stockroom station within the business operation. The quantity of product in partially filled containers is obtained by sensing the code, obtaining particular product information from the computer memory on the product identified by the code, and using the weight signal from the weighing device.

  • Patent number: 4437672
    Abstract: Apparatus for simulating the playing of golf includes a tee area from which a player may drive a golf ball toward a curved target screen in front of the tee area. Optical sensing devices are positioned to gather data as to the speed and distance of travel of a ball driven from the tee area. With the data from the sensing devices, computer apparatus produces an estimate for display of the distance of travel and ultimate resting position the driven ball would have if allowed free flight. Sensing devices also allow the computer apparatus to determine when a ball falls into a cup located in front of the target screen. If a ball enters the cup, and if the computer apparatus determines that the ball would have landed within a prescribed distance from the location of a target hole towards which the ball is driven, a "holed out" condition is presumed.
