How It Works
Mixed reality combines the immersive concept of VR with the interactive
concept of AR. In its simplest form, MR is a head-mounted version of AR. A
headset device with a lens allows the user to be immersed in the digital content
while still being aware of their physical surroundings, including other people.
They can interact with both digital and physical objects at the same time.
Using cameras and sensors, the headset measures the user's surroundings to
determine where the user is located in a room or space and then projects
digital content onto that space.
MR Applications in Construction
MR allows the user to merge a BIM model with their surroundings without
having to hold a device. The user can continue to conduct tasks as they
normally would while being guided by the MR headset, viewing and
interacting with the model with accurate, 1:1, surface-to-surface alignment.
Some examples of how to use MR:
• BIM designers can collaborate on creating a 3D model by "touring" a
building or structure before it's completed.
• Contractors can use MR to compare and install components on a
construction site according to manufacturer guidelines.
• Similar to AR, project teams can identify clashes with installed systems,
like electrical or plumbing, and bring them to the attention of a virtual
design and construction (VDC) manager to help resolve the issue.
Considerations
MR allows users to naturally interact with other people in the room or space,
which also makes it a good collaborative tool. While they can be used in outdoor
conditions, currently available MR headsets, like the Trimble XR10 with Hololens
2, work best and are safer when used in indoor environments.
