To use the Hololenses, each student must create an account. Designate a hololens for each student for the semeter so they do not have to worry about loggin in and out.

• Note: You must connect to an OPEN wifi to do the initial setup. The college wifi will not work as it requires you to go to the college website and authenticate. You will not be able to go to any website or put in any passwords for the initial setup. Students are recommended to turn on their phone hot spots (if they have one) and use that.
• Student phones should be connected to their providers connection, not the college wifi.
• Turn your phone wi-fi off.
• This only helps you get part way through setup. When you can no longer go any further, change the wifi connection to "Napa Guest" on the college wi-fi. This may require a reboot of the hololens.
• When you get connected to the wi-fi successfully, it will ask you to login to the work / school account. Use your napa valley email and password that you use everywhere else.
• It will ask you for verification on your phone.

Additional research still needs to be completed to find out what is the best pipeline.

• We spent most of the semester just getting Unity authorized so it could be used.
  • Note: During installation, a file is created that must be removed from the hard drive in order for the authorization to be completed.
  • Unity required Visual Studio and many additional components to be installed in order to work and export out to other devices.
  • LOD (Loading of Detail) Research needed. When you are far away, a low-res model is used but as you get closer in AR to your model, a higher-res model is used automatically.

Interactive Models:

• Unreal Engine with TwinMotion needs to be researched.
• Spatial.io (walk around campus for website)

To export out to Hololenses:

• You can use OneDrive to add models from the cloud but it is clunky.
• The best method to add models to the Hololens is to hook the Hololens directly to the computer using a USB-C cable and drag and drop the model using Microsoft Explorer. This is the easiest but it also gives you very limited options on controlling the model.
• If you want to add training controls to the model, you have to use “Dynamic 365 Guides”. We did not have time to research this any further.
  • Remote Assist is an additional tool that works with Dynamic 365 Guides. It allows you to view the hololens info on a table or mobile device.

To display Hololens Models on non-hololens devices:

• Miracast
  • Allows you to broadcast onto a television what is being viewed on the hololens.
  • Air Server is another option but this required purchasing a physical device that hooks up to the television.
• Microsoft 3D Viewer
  • Used be used to view your hologram on your local computer before transferring it to the Hololens.

The models created for Hololens must be REALLY optimized. We had very little success bringing in the entire campus that we had created. Further testing will need to be done once we create our final low-res versions. At this time we suggest only bringing in one building into AR at a time.

• To further optimize your models, we have several options to research:
  • Simplygon (3D Games Optimization)
  • Sketch Fab
  • Recap Pro to Mesh
