1. An apparatus for detecting a user activity, the apparatus comprising:
- a sensing data collector configured to collect sensing data from a sensor mounted on a mobile terminal of a user;
a location determiner configured to acquire posture data of the mobile terminal based on the collected sensing data, and to determine a location of the mobile terminal relative to the user based on the acquired posture data and location probabilities comprising probability increase conditions, wherein the probability increase condition is a modeling element about a condition that increases a probability of a presence of the mobile terminal at a representative location, with respect to possible locations of the mobile terminal relative to the user; and
an action determiner configured to determine the activity of the user based on the determined location of the mobile terminal relative to the user, the collected sensing data, and representative activities,wherein the action determiner is further configured to select the activity of the user, from among the representative activities, based upon the determined location of the mobile terminal relative to the user and a data pattern with a highest probability of matching the collected sensing data, andwherein the location determiner is further configured to select location candidates based on the acquired posture data and the location probabilities, and select the determined location of the mobile terminal relative to the user from the location candidates based on the collected sensing data from any combination of any two or more of a triaxial acceleration sensor, a proximity sensor, an orientation sensor, a terrestrial magnetism sensor, a display ON/OFF monitoring sensor, and a sound detection sensor.
