    摘要: A pointing device, a display apparatus and a pointing system, and a location data generation method and a display method using the same are provided. The pointing device includes a sensor that detects signals, a storage unit which stores a signal pattern and a controller which generates location data corresponding to a time at which a signal is detected. Using the detected signals, it is possible to more precisely determine a location of the pointing device on a display apparatus, and to minimize errors caused by delays that may occur when the pointing device is wirelessly connected to the display apparatus.
