August 4, 2007 Simulation has proven an effective method for training in many mission critical scenarios so it makes sense that this approach be adopted for the use of dangerous hand tools like chainsaws. To this end researchers have developed a type of hybrid virtual reality system known as the “Cybersaw” chainsaw - it looks like a chainsaw, feels like a chainsaw, sounds like a chainsaw and yet it only saws virtually. As soon as the starter is pulled, the motor starts to roar and with screaming saw in hand, the operator applies the real cutting bar to a perspex tree trunk in front of him. The virtual aspect is what the trainee sees on a projection screen behind the Perspex tree trunk - a sawhorse in the midst of an idyllic farm scene which the user can watch on the screen as the chain blade saws through the tree trunk, with the accurate simulation completed by the real feeling of resistance to the pine wood and the vibration of the saw.
