The HoloLens is used as a data input device connecting to data in the cloud to analyse, predict and show intelligent information to the user.
As the HoloLens is a device from Microsoft, it lends itself to being an input for Microsoft Cognitive Services. This means the device can send the same image seen by the user to be analysed using the Azure services on offer. See the "Apps" section for more details on applications being developed by Darbury.
