 The diesel program at Fox Valley Technical College in Appleton, Wisconsin uses the Hollle Microsoft Hollle lens to show our students how an engine actually works through the four cycles of combustion. The Hollle lens uses a series of voice commands in a 3D augmented reality object of an engine to reinforce that height engine shell. Those students are able to take a look at an engine's operation through the four strokes of combustion and the intake compression power and exhaust throughout all six cylinders during that. And that process is pretty unique. We can't take a look at running engines while they're operating, and it's pretty unique to be able to walk up to an engine show engine shell and actually become part of it. Kind of a unique image and a unique thing for a student to see height engine shell. So through this process it just reinforces the learning that we're doing in the classroom and allows them to speed some of that knowledge up.
