Abstract: A system and method for detecting and tracking multiple objects on a touchpad or touchscreen, wherein the method provides a new data collection algorithm, wherein the method reduces a calculation burden on a processor performing detection and tracking algorithms, wherein multiple objects are treated as elements of a single object and not as separate objects, wherein the location of the objects are treated as end-points of a single object when two objects are detected, and treated as a perimeter or boundary when more than two objects are detected.

Abstract: The creation of a checkerboard pattern of a plurality of conductive but electrically floating panels of conductive material that are disposed in the space between electrodes on the layers of X and Y electrodes, wherein each panel is separated from adjacent panels by a minimal gap, wherein the panels are aligned such that when viewed from above, the panels appear to form a continuous ITO surface, wherein the panels are not visible to the user from typical user distances, wherein the dis-color effect between etched empty fields and ITO electrodes is thereby eliminated by creating an apparently homogeneous touchpad surface.

Abstract: A method for executing single and multi-touch gestures that will be immediately recognized by the touchpad without having to wait for any portion of the gesture to be performed, thereby eliminating latency that can be caused by the touchpad or touchscreen having to wait for a portion of the gesture to be performed.

Abstract: A system and method wherein touchpad input including movement of a cursor and mouse clicks are inhibited until two events have occurred, namely, a timeout interval has elapsed and detection of movement of a pointing object a predetermined distance on the touchpad, wherein the system and method may also be implemented in touchpad firmware or hardware so that touchpad functionality beyond functions offered by an Operating System will travel with the touchpad and be available even when a software driver offering extended touchpad functionality is not installed or available for use.

Abstract: A method for using existing touchpad hardware to detect and track multiple objects such as fingers that are in contact with a touchpad, wherein the method extracts information from data that is already being collected, wherein analysis of the data is simplified by identifying objects by only looking for a positive slopes and negative slopes to identify multiple objects in data from the touchpad.

Abstract: A touchpad that operates in two modes, wherein a first mode enables the entire surface of the touchpad to operate in a typical detection single object detection and tracking mode to track the movement of a conductive object such as a finger anywhere on the surface of the touchpad and perform typical touchpad operations such as cursor control, and a second mode of operation wherein a button region of the touchpad is no longer used for the tracking of movement of a finger on the surface of the touchpad, but is instead dedicated to a button function if a finger on the touchpad pushes with sufficient force to activate a switch underneath the touchpad.

Abstract: A method of moving an object in a generally circular manner on the surface of a touchpad and causing a list to be scrolled as long as the object is moving, wherein a method is provided for activating a scrolling function, wherein a method is provided for determining what direction scrolling should occur based upon a direction of movement when scrolling is engaged, and wherein the direction of scrolling is only changed by an abrupt change in direction of the object.

Abstract: A touch-sensitive and far-field or proximity sensitive touchpad combined with a display, wherein the touchpad is formed as a touchstrip that is concealed inside the display, wherein a first function or interface such as a menu is enabled when an actuating device reaches a threshold distance from the touchpad, wherein a second function or interface is enabled when the actuating device makes contact with the touchpad, and wherein the first function may or may not continue after contact is made with the touchpad.

Abstract: A method of using a capacitance-sensitive touchpad, wherein the touchpad includes a zone on a surface thereof, wherein touchdown of a pointing object within the zone enables activation of a scrolling function, wherein direction of scrolling is then controlled by a gesture by the pointing object, such as moving in a circular motion in a clockwise direction to move down in a list, and in a counter clockwise direction to move up in a list, and wherein fast and slow scrolling speeds are controlled by tapping functions within the scroll zone.

Abstract: A method of using proximity sensing to detect and track movement of a detectable object that is making a gesture in a three-dimensional volume of space in a detection volume of a proximity sensitive touchpad.

Abstract: A physical or virtual circular touchpad that may have an active touch-sensitive surface in a center area of the touchpad, wherein touchdown in the center area is detected by the touchpad having an active touch-sensitive surface, and then radial movement from the center area towards a perimeter of the circular touchpad and in a specific direction will cause a change in the value of a control parameter.

Abstract: A method of activating and using a scrolling function on a touchpad, wherein the touchpad must be capable of simultaneously detecting two fingers on the touchpad surface in order to first implement a scrolling activation function which is separate from a subsequent scrolling use function.

Abstract: A simplified touchpad which detects a “touch” in a specific absolute positioning programmable zone or “enter/select” zone rather than requiring a “tap”. The touchpad also has an audible feedback device built into the touchpad for immediate feedback and a touch sensitive surface comprising a relative cursor positioning zone. By simplifying a touchpad to include only basic functions, the touchpad is easier to operate, simpler to manufacture, and more amenable to use with graphical interface display systems typically using touch screens. The invention is preferably incorporated into a kiosk where simplified use is of great benefit. An embodiment of the invention includes an enclosure which completely seals the touchpad from external contamination, thereby making the touchpad waterproof and dust proof. A cover plate also provides durability and added protection for the touch sensitive surface of the touchpad.

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.
