Abstract: The disclosure provides an electronic device adapted to communicate with a stylus. The electronic device includes a display panel, a touch module, and a processor. The display panel has a display area, the touch module has a touchable area, and the processor is electrically connected to the display panel and the touch module. The processor is configured to: define at least one effective input area in response to an operation of the stylus in the touchable area, and when the touch module detects that the stylus is approaching the effective input area, switch the effective input area to a stylus mode, and display a range marking pattern in the effective input area.

Abstract: Used in a touch mouse having housed in a touch mouse for transmitting a control signal to a computer for cursor control, the touch mouse having a touch-control circuit board bonded to the inner surface thereof, the touch-control circuit board comprising two deepest main notches and at least one sub-notch on the periphery thereof to provide multiple touch control induction zones. When a user touches the touch mouse to produce a touch signal, the location of the touch signal is calculated and then processed through a comparison procedure to determine whether or not the touch signal falls upon multiple touch control induction zones, and then it is to enter a first touch-control operation mode when positive, or to determined whether or not the touch signal falls upon one single touch control induction zone when negative. When the touch signal falls upon one single touch-control induction zone, it is to enter a second touch-control operation mode.

Abstract: Used in an input device having a housing thereof sensor modules and a circuit substrate carrying a control module, a touch panel, a displacement sensor module, a transmission module and a power supply module to control a computer comprising a driver software, an input device multi-direction control processing method is to detect the location of the presence of an external object on the surface of the housing of the input device by the sensor modules so that the sensor modules provide location signals to the control module upon the presence of an external object at the surface of the housing, for enabling the control module to store the location signals and to further transmit the location signals and displacement coordinate signals received from the displacement sensor module to the driver software of the computer for calculating a new coordinate system and translating the new coordinate system into a track signal for cursor control.

Abstract: Used in a multimedia operating system for controlling multiple computers, an input device includes a memory unit adapted for storing the ID codes of the computers, a control unit adapted for receiving an external switching signal and fetching the ID code from the memory unit subject to the content of the received external switching signal and then producing a switching packet containing the fetched ID code, a wireless transmitter and receiver unit adapted for transmitting the switching packet produced by the control unit to the computers, and a power supply unit adapted for providing the input device with the necessary working power supply.

Abstract: An input device includes a housing having an outer surface for touching by an external object, object sensors mounted in the housing for sensing the location of an external object touching the outer surface of the housing and generating a corresponding location signal, a displacement sensor module for sensing the amount and direction of movement of the housing and generating a corresponding displacement coordinate signal, and a control module for calculating track signals subject to received location signals and displacement coordinate signals for transmission to an external computer for cursor control.

Abstract: A wireless touchpad mouse includes a housing defining a start-up region and a control module mounted in the housing. When the user touches a start-up region of the housing, a switch unit is switched on. When received the switching signal from the switch unit and a static signal from a touch panel, the microprocessor of the control module samples the resonance frequency of the sound wave detected by a sound wave sensor, and drives a transmitter module to transmit a displacement signal indicative of the movement of the housing to an external electronic device for cursor control after recognition of the resonance frequency to be within a predetermined reference value.
