Recent technological advances have enabled several alternatives for developing motion capture systems at low cost. These systems, in turn, can be used in different applications, such as independent games or movies. This paper aims at evaluating and discussing about this statement. Based on the evaluation, it proposes what would be the best cost-benefit system that can be build with the current ...

Quantitative measures of the space an individual can reach is essential for tracking the progression of a disease and the effects of therapeutic intervention. The reachable workspace can be used to track an individuals’ ability to perform activities of daily living, such as feeding and grooming. There are few methods for quantifying upper limb performance, none of which are able to generate a r...

The determination of the instantaneous axis of rotation of human joints has numerous applications. The screw axis can be determined using optical motion capture systems or electromechanical goniometers. In this paper, we introduce a new method for the localization of the instantaneous screw axis in human anatomical joints from the data given by a spatial mechanical goniometer.

In this paper, we describe and analyze a corpus of speech data that we have recorded in multiple modalities simultaneously: facial motion via optical motion capturing, tongue motion via electro-magnetic articulography, as well as conventional video and highquality audio. The corpus consists of 320 phonetically diverse sentences uttered by a male Austrian German speaker at normal, fast and slow ...

Here we introduce our new text-to-AV (speech and face animation) system created for our Thinking Head project that provides a modular research platform to the AV community. This includes a novel phone-to-face motion module capable of synthesizing face animation from triphone data. Using phoneme timing information from human speech and combining this with information derived from our speech face...

Motions of organs or extremities are important features for clinical diagnosis. However, tracking and segmentation of complex, quickly changing motion patterns is challenging, certainly in the presence of occlusions. Neither state-of-the-art tracking nor motion segmentation approaches are able to deal with such cases. Thus far, motion capture systems or the like were needed which are complicate...

The paper presents how the concept and technology of Open Badges are applied in the GRASS project for acknowledging, grading, awarding and recognizing learners' efforts and achievements in developing their soft skills (like self-regulation, leadership, collaboration, skilled communication, problem solving and innovation). Specifically, the paper describes a 4-phase model, called SAGRADA that wa...

Watching athletes allows coaches to provide both vital feedback on how well they are performing and on ways to improve their technique without causing or aggravating injuries. The thoroughness and accuracy of this traditional observation method are limited by human ability and availability. Supplementing coaches with sensor systems that generate accurate feedback on any technical aspect of the ...

We present a method for characterizing coverbal gestural units intended for human-avatar interaction. We recorded 12 gesture types, using a motion-capture system. We used the markers positions thus obtained to determine the gestural units after stroke segmentation. We complement our linguistic analysis of gestures with an elaboration of our biomechanical hypotheses, our method of segmentation, ...
