INTERACTION IN VR
A training simulator by Controllab
Over the years we gained a lot of knowledge and experience on how to build both traditional and innovative training simulators. When it comes to training simulators, Virtual Reality (VR) is one of those new and innovative technologies that has brought a complete new world of possibilities. This blog item briefly describes some of the thoughts and actions behind implementing an intuitive controller implementation for training simulator, based on our own experiences, that includes VR.
We replaced the touch controllers by physical joysticks that are mounted on a desk chair. The chair has been made wireless using a form of wireless communication and a battery pack. The locations of the joysticks in the real world were identical with those in the virtual environment, such that the operator can feel the joysticks at the exact position where he sees them in VR. We noticed that when using these joysticks, inexperienced users operate the crane much more accurate. However, this only works due to the simplicity of the joysticks. If the joysticks become more advanced, for example a control pad that has multiple joysticks, buttons and displays, it becomes too difficult to differentiate between the several buttons and joysticks that you see and those that are present in reality. This is mainly because there is almost always a small discrepancy between the location of the joystick in the real world and the joystick in the virtual world.
