Abstract:
This seminar aims to present new trends, methods and applications related with the simulation and interaction of objects and agents present in a Virtual Reality (VR) Environment. In the first part of this seminar we will introduce some concepts and new techniques used in the development of VR applications: 3D visualization, immersion and interaction; VR devices and Haptic devices; Augmented Reality; Mixed Reality. Then, we will discuss about the introduction of interaction based on physics, including concepts related to perception, action, kinematics and dynamics (including rigid body dynamics and flexible/deformable objects). The physical and behavioural simulation into a VR environment allows us to design, test and improve our engineering projects: from simple mechatronic components to complex autonomous mobile robots (e.g. vehicles and humanoid robots). Some tools used to implement these systems will be also presented, as for example, OSG/ODE. After discussing about physical interaction between VR agents and elements, then the second part of the tutorial will focus on the behavioural simulation of virtual autonomous agents. We will see different simulation techniques used to control agents’ behaviour, including autonomous agent control architectures (e.g. deliberative, reactive and hybrid architectures). The introduction of knowledge about/into the agents (e.g. memory, emotional states, personality, personal profile) and about the environment (e.g. special places, functioning rules, place profile, active and intelligent objects), will be also addressed. The knowledge introduced is then used to improve the simulation and some aspects related to the agents’ autonomy, the interaction within the VR environment, and the degree of reality in the VR simulations. We conclude this seminar with some examples of practical applications, including recently developed VR applications implemented by our research group: intelligent virtual reality environments (IVRE), VR simulation tools for autonomous parking of vehicles, and simulation of walking machines and autonomous robots/agents.
