  • Method for writing motion and trajectory recognition and writing apparatus and recognizing system
    Patent number: 8259092
    Abstract: The present invention provides a method for writing motion recognition, wherein a sound signal generated when a writing apparatus is contacting and moving on a writing surface is acquired. According to the occurrence of the sound signal, the writing apparatus can be determined whether it is on the writing surface or not. In another embodiment, the present invention further provides a method for writing trajectory recognition, wherein the foregoing method and character recognition techniques are combined to convert a writing trajectory into a character. In addition, the present invention further provides a writing apparatus and a recognition system, wherein a device is installed in the writing apparatus for collecting sound signal generated during the writing process and a processing unit which adapts the foregoing method is used to recognize the motion trajectory of the writing apparatus so as to form the corresponding character.

  • Real-time motion recognition method and inertia-sensing and trajectory-reconstruction device using the same
    Patent number: 8229226
    Abstract: The present invention provides a real-time motion recognition method for identifying whether an inertia-sensing device is in active state or not according to an angular velocity signal detected with respect to the device. The present invention further provides an inertia-sensing and trajectory-reconstruction device incorporated with the foregoing method for recording detected acceleration and angular velocity signals while the device is in operation so as to reconstruct a corresponding trajectory which is capable of being subsequently utilized to be a basis of writing recognition and motion analysis.
