The LEAP Motion controller is a small inexpensive device that allows for the tracking of the user’s hands and fingers in three dimensions. The most significant difference is the possibility to allow interactions beyond touching a screen. Unlike applications running on mobile devices, stationary setups can be extended more easily with additional interfaces and thus allow for more complex interactions and simulations in virtual reality (VR) and augmented reality (AR). Within the context of our intended blended learning concept we want to utilize augmented or virtual reality techniques for stationary laboratory exercises. In our previous publication we demonstrated the use of augmented reality visualization techniques in order to let the students prepare with a simulated experimental setup. a lens experiments the students need access to an optical bench, various lenses, light sources, apertures and a screen. Most experimental setups require special hardware. Even simple exercises can improve the understanding of the underlying subject. Practical exercises are a crucial part of many curricula.
