摘要:
In a method for functioning a mouse Zx scroll with a standard mouse driver, a pair of middle-button signals of a mouse are generated by a standard mouse driver of Microsoft to sandwich a horizontal movement amount signal when scrolling a horizontal scroll bar of a window by a Zx mechanism of the mouse. Since the horizontal scroll bar is operated only by the standard mouse driver of Microsoft, there is no need of additional or specific mouse driver for the Zx function of a mouse.

An apparatus comprises a case, one or more capacitive touchpads mounted on the case for serving as the input interface of the apparatus, and a microprocessor within the case connected to the capacitive touchpads. Each of the capacitive pads generates a signal representative of capacitance change in response to a touch thereon, and the microprocessor determines the displacement, moving speed, relative position, or continuing and discontinuing time of the touch from the signal representative of capacitance change, to accordingly generate corresponding output as a button, Z-axis or scrolling signal.

A mode switch apparatus for an optical mouse comprises a capacitive touchpad mounted on a housing of the optical mouse, and a microprocessor connected to the capacitive touchpad. When a user's hand touches or leaves the capacitive touchpad, a signal representative of capacitance change is generated in response thereto, and the microprocessor switches the optical mouse from a first mode to a second mode, or from the second mode to the first mode, in response to the signal representative of capacitance change.
摘要:
In a capacitive touchpad, a plurality of sensing zones are defined, and a controller is connected with a plurality of scan lines for sensing a movement of an object slipping on the plurality of sensing zones, wherein at least one of the plurality of scan lines is connected to at least two of the plurality of sensing zones. The distance, speed and direction of the movement are determined by detecting the object on the touchpad at two positions upon two scans, and thereby the control of a scroll bar is accomplished. The capacitive touchpad is applied for a Z-axis arrangement on a mouse and a scroll arrangement on a keyboard.

In a method for scroll bar control on a touchpad, the fingers touching on the touchpad are detected to start up and terminate a scroll bar control function. In the scroll bar control function, the movement of the finger or fingers touching on the touchpad is detected for scrolling on a window, and the vertical distance and the horizontal distance of the movement are evaluated for determining the scrolling amount of a vertical scroll bar or a horizontal scroll bar of the window.
摘要:
A capacitive touchpad integrated with key and handwriting functions is provided for operation in key, handwriting and mouse modes. Several regions are defined on the panel of the touchpad and have several patterns printed thereon for the operation modes thereby. In the key mode, the key patterns among the printed patterns simulate a keyboard. In the handwriting mode, the handwriting region among the defined regions serves to handwriting input. In the mouse mode, the defined regions provide a cursor moving region and a horizontal and vertical scroll bars for input operations.
