Knowledge tracking is a task that involves predicting the probability of a student correctly answering a particular exercise. It utilizes the answer interaction data of all students to forecast the answering performance of an individual student. ...

Interpersonal skills, including collaborative problem solving (CPS) and negotiation skills, are essential in many aspects of the 21st century. With the rapid development of technologies in the past decades, it has become increasingly prevalent ...

• We study how team members' personalities and the interaction processes impact performance on virtual tasks.
• Relationships between personality, interaction processes, and performance differ in collaboration and negotiation contexts.

We have developed a novel and affordable way to texture virtual hands from individually taken photographs and integrated the virtual hands into a mixed reality neurorehabilitation system. This mixed reality system allows for serious game play with ...

Vision-based 3D hand tracking is a key and popular component for interaction studies in a broad range of domains such as virtual reality (VR), augmented reality (AR) and natural human-computer interaction (HCI). While this research ...

In most gesture recognition research fields, feature extraction is based on single finger. In this paper, we propose an improved finger feature extraction algorithm based on double fingers, and it is easier to judge the projected distance and angle of ...
