The Teaching Factory concept utilizes advanced delivery mechanisms and high-grade industrial didactic equipment to offer education content. It connects remotely located engineering teams with teams of students in the classroom or laboratory so as work together in a common engineering project in manufacturing. This work investigates the potential of using Holograms as key technology for delivering educational content to the classroom side. The holographic system enables the visualization of complex 3D models in real-size dimensions enabling concurrent 3D visualization of the models to a team of students. A prototype has been implemented that offers the collaboration tools to both sides of the Teaching Factory setup. On the classroom or laboratory side, interaction is enabled through gesture recognition upon a low-cost finger tracking device, while on the factory side interaction as well as visualization is possible using tablet or mobile devices. Both sides can simultaneously interact with 3D object being displayed in holographic and mobile displays. Additional interaction functionality such as display annotations, tree view of the geometrical object and content management is offered though the mobile app.
