Many HAR (Human Activity Recognition) systems are able to detect sequential executed ADL (Activity of Daily Living). While a person is capable of doing two things in parallel or to pause one ADL and finishing it later a HAR system (HARS) must be capable ...

We present a comparative experimental evaluation of three methods that estimate the 3D position, orientation and articulation of the human body from markerless visual observations obtained by RGBD cameras. The evaluated methods are representatives of ...

Inferring a user's current situation is the basis of context-aware services. However, users rarely provide access to their sensor data, and hence extracting context information remains challenging in real-world scenarios. In this paper, we present an ...

In sign languages, a periodic sign is one that contains repeated movements. Dynamic Time Warping (DTW) is often used in sign language recognition to generate a frame alignment between two input signs that provides a measure of their similarity. ...
