Abstract: Disclosed is a system for recognizing a user location using sensor-based activity recognition. The system includes a mobile device which includes a sensor module configured to sense information about at least one of a user state and surrounding environments, a first processor configured to extract activity information based on the sensed information, and a first communication module configured to transmit the extracted activity information; and a user terminal device which includes a second communication module configured to receive the activity information from the first communication module, and a processor configured to determine a user location in a user space corresponding to a user activity based on the received activity information. By determining a user's location in a user space corresponding to a user activity, it is possible to control electronic devices corresponding to the user activity or provide a service of monitoring activities of the old and weak and the child.

Abstract: A data generator includes an over drive data generator and a buffer. The over drive data generator generates an over drive data based on a previous display data and a current display data. The buffer provides the previous display data to the over drive data generator. The buffer stores the current display data and the over drive data. The buffer outputs the current display data and the over drive data. The data generator may increase the speed of driving the load connected to a display driver using the over drive voltage corresponding to the over drive data. If the speed of driving the load connected to the display driver is increased, the operational speed of the display device may be increased.
