HOW DOES A TABLET PC STORE HANDWRITING? A touch sensitive screen is used to record the movement of a stylus. As a user takes notes on the screen, software digitizes the handwriting, and converts it into text that can be stored on the computer. It is necessary to go through a calibration procedure in order for the computer to interpret an individual's handwriting correctly. Previous systems were able to interpret cursive writing the best, but the Tablet PC can recognize cursive, print, or even mixed writing.
ELECTRONIC WHITEBOARD: Using optics and ultrasound, a new electronic whiteboard digitally captures every written word that is written on it. First, a user mounts a receiver to the corner of any whiteboard. When a dry-erase marker fitted into a special sleeve touches the board, the sleeve sends out infrared and ultrasound waves. These waves trigger the receiver to track the writing. A computer then re-creates every stroke, which can be sent to multiple terminals.
VIRTUAL LABS: In addition to the all-in-one textbook, notebook, and computer offered by the Tablet PC, students learning science in the classroom can now learn basic science concepts online. The virtual lab, developed by engineers and students at the University of Virginia, guides students through 50 experiments, along with text and vivid animations that explain how things work -- like semiconductors and generators.
