Product Description
Brand : Microsoft
Model : Dynamics 365 Field Service and HoloLens2
Guides
Guides are effectively a mixed reality training walkthrough. In more basic terms this means you can see the real world around you while descriptive steps, animated actions and pointers will guide you on specifically where to go and what to do.
Remote Assist
Remote Assist is also a mixed reality tool to help provide field service engineers or technicians with expert assistance from afar. The engineer who has the HoloLens can hold a mixed reality call with an expert or another engineer who is also using a HoloLens or Microsoft Teams on their mobile device or desktop.
