This article presents a training system for live-line workers. The developed training system is based on immersive virtual reality and automatic speech recognition technology. The training is focused on live-line Cut-Out-Switch (COS) replacement work in a distribution system. Most work in power systems must be free of interruption, so it is carried out by live-line techniques. However, these te...

BACKGROUND The study aim was to compare the effectiveness of virtual reality and computer-enhanced videoscopic training devices for training novice surgeons in complex laparoscopic skills. METHODS Third-year medical students received instruction on laparoscopic intracorporeal suturing and knot tying and then underwent a pretraining assessment of the task using a live porcine model. Students w...

Virtual simulations, computer games, and other game-like virtual worlds are progressively being adopted for “serious” purposes, such as training and education. Computer-based training systems and games share many similarities: both involve a progression of skill-based activities of increasing complexity and difficulty. The learner is expected, over the duration of the game, to master a set of s...

Sound has a multitude of applications in areas ranging from engineering, architecture, entertainment, to environmental noise control. Sound also plays a crucial role in immersive virtual environments with studies showing it can improve the sense of presence and fidelity in training, simulation, education, and entertainment. This makes it important to simulate sound in a perceptuallyaccurate way...

BACKGROUND Traditionally, training in gastrointestinal endoscopy has been based upon an apprenticeship model, with novice endoscopists learning basic skills under the supervision of experienced preceptors in the clinical setting. Over the last two decades, however, the growing awareness of the need for patient safety has brought the issue of simulation-based training to the forefront. While the...

 Virtual Reality (VR) systems allows the design of interactive and immersive environments for the simulation of a wide range of situations. These features has been exploited to build realistic applications in order to provide study and training in several areas, particularly in medicine. In this sense, the addition of techniques to assess the actions of users can provide simulations based on v...
