Mixed reality (MR) is a technology where 3D holograms are superimposed onto a physical environment. A first-person, immersive experience is achieved through the user accessing these 3D holograms through a head-mounted display. In MR, the user still has full cognition of the physical environment because the user can see through the headset. This paper will walk through the design steps undertaken by the team to develop an MR laboratory module for chemical engineering. The MR module in this study is a digital twin of the fluid flow through pipes equipment that is used for undergraduate instruction. This work follows on from the proof-of-concept discussed in a previous publication and includes increased functionality, and opportunities for tracking student use to evaluate if MR is an enhancement for student learning in an engineering context.
