They are essentially based on two components: − Sensors for controlling the virtual world; − Effectors to provide feedback to the user. Researchers have been developed methods to dynamically measure human movement in real-time through clothing equipped with sensors that track the full range of actions of specific activities carried out by the wearer. The movement is recorded, digitized, and then sent to the computer, which displays them on the screen, replicating all the actions performed in real-time. directional sensors to transmit electrical signals corresponding to the wearer's movements to a computer. These signals are then converted into digital form, and the resulting data are displayed in the virtual environment. We often use gloves in conjunction with a position and orientation sensor that allows the computer to determine spatial coordinates. They can also be used in conjunction with suits and associated with HMD. Finally, the viewers called HMD are devices that allow the wearer to immerse themselves in virtual reality. They include a head-mounted stereoscopic display and provide separate images for each eye, a stereo sound, and an ahead motion tracking sensor. We can distinguish three types of virtual reality: • Immersive Virtual Reality (RVI)), characterized by the intense sensation of immersion in virtual space thanks to the interaction with the virtual objects present. • Non-Immersive Virtual Reality, the simulated environment does not stimulate the sense of immersion; it is perceived as the real one. • Augmented Reality (AR) enriches the objects in the real world with perceptual information produced by the computer through multiple sensory modalities (visual, auditory, tactile). Below is a brief overview of the state of the art V. B ackground The functionality of a virtual reality system requires different tools: modeling programs with which objects for the virtual world are created; moreover, to generate dynamics in real-time, simulation systems that follow natural laws are needed to move objects in the virtual world. For example, robust programs for viewing 3D images and spatialized sounds in real-time are also used. In addition, traditional systems used to communicate with a computer are no longer suitable for the multidimensional virtual world. These interface mechanisms are found in apparel, head-mounted displays (HMDs), and 3D sound systems. This clothing consists of gloves and suits. Gloves are interactive devices, similar to a typical glove worn on the hand, facilitating tactile sensing and refined motion control. Tactile sensing involves simulating the sense of touch and includes the ability to sense pressure, linear force, temperature, and surface structure. Through the control of the fine movement achieved with sensors, the actions of the user's hands and fingers are detected. These movements are then translated into signals that can be used by a virtual hand to allow the user to interact normally with the objects in the virtual environment. The suit wraps the body with This section reports significant experiences developed based on neural networks combined with virtual reality. Through the analysis of facial expressions, it is possible to understand the emotional state. Neural networks coupled with virtual reality represent a valid platform for analyzing human behavior and effectively treating individuals with autistic disorders. Virtual reality (VR) offers distinct advantages over conventional
