摘要:
A pointing device and a display apparatus applying the same are provided. The pointing device corrects an error that occurs in a boundary between block in calculating a current location of the pointing device and calculates the current location. Accordingly, an error occurring in a boundary between blocks in calculating a current location of the pointing device is prevented.
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.

Disclosed are an input device, a method of controlling the input device and a system including the input device and a display device. The input device may include: a communication unit operable to communicate with a display device; a sensor operable to sense a first signal containing noise and a scan signal generated from the display device, and a second signal containing the noise; a noise eliminator operable to compare the first signal and the second signal; and a controller operable to control the communication unit to output position information of the input device, wherein the position information is based on the comparing of the first signal and the second signal.
