Virtual Human System 2020 (25x)


This text appears to be discussing the use of virtual human systems, which are computer-generated characters that simulate face-to-face conversations using verbal and nonverbal cues, in a variety of contexts. These systems can include virtual human coaches, artificial intelligence dialogue systems, and interactive skills training systems, among others. The text also mentions the use of these systems in areas such as health care, education, and training, as well as the role of deep learning in the development of such systems. The text also mentions the importance of speech recognition and the use of quaternions in representing joint rotations in virtual human systems. Finally, the text discusses the potential benefits and ethical implications of using conversational agents in global public health.

Quaternions are a mathematical construct that allow for the representation of three-dimensional rotations in a four-dimensional space. They are used to represent joint rotations in virtual human systems because they are free of discontinuities and singularities in the representation space.

In virtual human systems, quaternions can be used to represent the rotations of joints in a character’s skeleton, allowing for smooth and accurate animations of the character’s movements. This is important for creating realistic and believable virtual human characters that can interact with users in a natural and intuitive way.

To use quaternions to represent joint rotations, the quaternion is first initialized to represent the initial orientation of the joint. As the joint rotates, the quaternion is updated to reflect the new orientation. This updated quaternion is then used to transform the joint’s position and orientation in the virtual human’s 3D model. This allows the virtual human to move and behave in a way that is consistent with the joint rotations represented by the quaternion.
