Virtual Human

This paper focuses upon the research and development of a prototype dental simulator for training of periodontal procedures. By the use of virtual reality and haptics technology, the periodontal simulator allows trainees to learn performing diagnosis and treatment of periodontal diseases by visualizing a three-dimensional virtual human mouth and feeling real tactile sensations while touching the surface of teeth, gingiva,

This paper describes a fast technique for dressing virtual humans with different pieces of clothing. It exploits a mass-spring cloth model but applies a new velocity modification approach to overcome its super-elasticity. The algorithm for cloth-body collision detection and response is based on image-space interference tests, unlike most of the existing ones, which use objectspace checks. The modern workstations ’ graphics hardware is used not only to compute the depth maps of the body contours but also to interpolate the body normal vectors. As a result the approach is very fast and makes it possible to sew a garment around a virtual human body in about a second.

Since l986, we have led extensive research on simulating realistic looking humans. We have created Marilyn Monroe and Humphrey Bogart that met in a Cafe in Montreal. At that time, they did not wear any dress as such. Humphrey's body was made out of a plaster model that has the shape of a suit. Colors on Marilyn's body looked like a dress. Hairs were simulated as a global shape and skin was a color. Since then, we have developed extensive research to simulate real virtual deformable clothes wearing by virtual humans. We also needed to have appropriate simulation of a skin and recently, we have developed new research on skin in order to decrease the plastic color of our synthetic actors. Also there was a need to simulate hair in an efficient way. New methods have been developed, both for design and animation purpose that are compatible with the clothes module. In this paper, we like to introduce our most recent research results on these topics. We are now able to simulate to...

The enhancement of physical attractiveness through body modifications, such as tattoos is evident in a wide range of cultures and has recently become popular also in Westernized societies. Evolutionary psychologists have suggested that these invasive body modifications could possibly act as handicap signals in sexual selection. However, knowledge about the actual signalling quality of body modification and its perception is still scarce. In this present study a sample of 278 men and women rated images of tattooed and non-tattooed virtual ...

When dealing with large, distributed systems that use state-of-the-art components, individual components are usually developed in parallel. As development continues, the decoupling invariably leads to a mismatch between how these components internally represent concepts and how they communicate these representations to other components: representations can get out of synch, contain localized errors, or become manageable only by a small group

Highly realistic virtual human models are rapidly becoming commonplace in computer graphics. These models, often represented by complex shape and requiring labor-intensive process, challenge the problem of automatic modeling. This paper studies the problem and solutions to automatic modeling of animatable virtual humans. Methods for capturing the shape of real people, parameterization techniques for modeling static shape (the variety of

Individuals with body modifications, such as tattoos, have been shown to differ from nonmodified individuals in sensation-seeking personality characteristics and sociosexuality. This study examined possible differences in people’s attributions of those characteristics toward virtual human characters varying in body modification. Some 287 participants rated tattooed and nontattooed bodies of avatars on aspects of sensation seeking and number of previous sexual

BioSimMER (Bioterrorism Simulated Medical Emergency Response) is a Virtual Reality-based mission rehearsal and training environment. BioSimMER employs contingency-oriented, multiple-path algorithms and MOESINIOPS focused on real-world operations. BioSimMER is network-based and immerses multiple trainees in a high resolution synthetic environment, including virtual casualties and instruments that they may interact with and manipulate. Trainees are represented as individuals by virtual human Avatars. The simulation consists of several components: virtual casualties dynamically manifest the symptoms of their injuries and respond to the intervention of the trainees. Agent transport analysis is used to simulate casualty exposures and to drive the responses of simulated sensors/detectors. The selected prototype scenario is representative of combined injuries anticipated in BW operations.

This paper provides key insights into the construction and evaluation of interpersonal simulators - systems that enable interpersonal interaction with virtual humans. Using an interpersonal simulator, two studies were conducted that compare interactions with a virtual human to interactions with a similar real human. The specific interpersonal scenario employed was that of a medical interview. Medical students interacted with either a virtual human simulating appendicitis or a real human pretending to have the same symptoms. In study I (n=24), medical students elicited the same information from the virtual and real human, indicating that the content of the virtual and real interactions were similar. However, participants appeared less engaged and insincere with the virtual human. These behavioral differences likely stemmed from the virtual human's limited expressive behavior. Study II (n=58) explored participant behavior using new measures. Nonverbal behavior appeared to communicate lower interest and a poorer attitude toward the virtual human. Some subjective measures of participant behavior yielded contradictory results, highlighting the need for objective, physically-based measures in future studies

th IFAC Symposium on Analysis, Design, and Evaluation of Human-Machine Systems, Atlanta, 2004) Abstract: Some installations of human-machine interactions aiming at a close integration of art, science and technology will be presented. Several projects originating from a course Production Informatics have resulted in public performances demonstrating some aspects of a combination of real and virtual, human and machine performances: Theater of Machines, Media and Theatre (Methea), Theater in virtual Worlds, Mixed Reality Stages.
