Social motor coordination remains a relatively overlooked dimension of social behavior in children with ASD. One reason for the lack of research is that the motion tracking equipment historically used for recording body movements of children during social interaction has been very costly, as well as cumbersome and impractical. Here we examined whether two low-cost motion-tracking options can be...

The notion that cognitive processes ”leak” into motor output of decisions inspired much recent process-tracing research. In mouse-tracking, an increasingly popular decision-making paradigm, difficult choices lead to increased curvature of the mouse trajectories towards the unchosen option. Here we explore whether traces of a decision process can be found in its motor output in a more naturalist...

Task-evoked pupil response (TEPR) has been extensively studied and well proven to be sensitive to mental workload changes. We aimed to explore how TEPR reflects mental workload changes in a surgical environment. We conducted a simulated surgical task that has 3 different subtasks with different levels of motor precision and different mental workload requirements. We found a significant effect a...

In this paper, a novel framework for visual tracking of human body parts is introduced. The presented approach demonstrates the feasibility of recovering human poses with data from a single uncalibrated camera using a limb tracking system based on a 2D articulated model. It is constrained only by biomechanical knowledge about human bipedal motion, instead on relying on constraints linked to a s...

Software development’s organizational design is often characterized by geographical dispersion and virtual team work. In this setup, communication is an essential task. We study this task by analyzing the association between communication structure and efficiency of the issue tracking process. This key process within software development is primarily carried out digitally and thus provides a su...

In this article, we present an object tracking system which allows interactive user feedback to improve the accuracy of the tracking process in real-time video. In addition, we describe the hybrid maximum likelihood similarity, which integrates traditional metrics with the maximum likelihood estimated metric. The hybrid similarity measure is used to improve the dynamic relevance feedback proces...

With the rapid globalization of Information Technology, it is important not only to evaluate performance, but also to understand the underlying causes of performance differences among populations when using computer interfaces. In this study, the search strategy of three different groups of users (Mainland Chinese, Hong Kong Chinese and Nonnative Chinese readers) was assessed. A full screen sea...

by the hand movements performed by humans that are tracked by a magnetic tracking device [9]. These reported steps are important to understand some human behaviors before the object manipulation and can be used to endow a robot with autonomous capabilities, like showing how to reach some object for manipulation or object displacement.

In den vergangenen Jahren entwickelte sich Magnetresonanztomographie (MRT)-geführte Brust-Biopsie zu einer der vielversprechendsten Verfahren innerhalb des Feldes der interventionellen Magnetresonanztomographie (iMRI). Die vorliegende Arbeit präsentiert ein neu entwickeltes Verfahren zur verbesserten Echtzeitnadelführung unter Nutzung eines optischen Moiré Phase Tracking (MPT) Systems. Es ermög...
