This research developed an application that could tracks and locates human's presence and position in indoor environment using multiple depth-cameras. Kinect as the most affordable device that equipped with depth-camera was used in this work. The application obtains stream data from kinect and analyzes presence of human using skeletal tracking library on kinecth for windows SDK vI. The final application also visualizes human location on 3D environment using windows presentation foundation (WPF) 4.0 In order to visulize 3D object correctly, the application also took into account the coverage that may interesect when two kinects were olaced in adjacent position so that the final human location is combined. In the end, application was tested in 3 different scenarios and it's found that the average error in determining human location was 0.13589 meters.
