Abstract

After implementing a motivational model of action selection applied to autonomous virtual humans inspired by models of animals' decision-making, the problem consists of testing it in good conditions for validation. Indeed this model has to respect the six criteria that we define according to Tyrell's requirements for designing a mechanism of action selection. So we use the real-time framework VHD++ for advanced virtual human simulation and we define a simulated environment with many conflicting motivations. Finally a video shows the first results where the virtual human's decision-making follows the six criteria and so validates our model in the simulated environment

Virtual reality

Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry.

Virtual world

A virtual world (also called a virtual space) is a computer-simulated environment which may be populated by many users who can create a personal avatar, and simultaneously and independently explore the virtual world, participate in its activities and communicate with others. These avatars can be textual, graphical representations, or live video avatars with auditory and touch sensations. Virtual worlds are closely related to mirror worlds.

Simulation

A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Often, computers are used to execute the simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games.
