  • Patent number: 8780040
    Abstract: A handwriting input device includes a housing and a nib selectively exposed from a bottom side of the housing or hidden in the housing. The device further includes a pressure sensor, a motion sensor, and a microcontroller. The pressure sensor generates pressure signals when the nib is depressed. The motion sensor senses movement of the device. The microcontroller records the sensed movement upon receiving the pressure signals, and processes the recorded movement to obtain track signals of handwritten information when the duration of not receiving the pressure signals exceeds a predetermined time interval. The track signals of handwritten information are then transmitted to an external electronic device communicating with the device to become handwriting shown on a display of the external electronic device.
