Project North Star
Project North Star is an open-source augmented reality headset originally created by Leap Motion. A northstar headset uses a curved reflector. The headsets typically require calibration to correct for geometric distortions introduced by the reflector. There are multiple different versions, including the original release, and the Deck X. It is named "North Star" because it represented a guiding direction that Leap Motion wanted to go in.
Headsets can be partially 3D printed.
A northstar headset requires a computer to connect to using Displayport and USB.
Hardware[edit]
The Project North Star headset is an optical-see-through head mounted display (OST-HMD). Project North Star headsets use a reflector style design.
Project North Star headsets generally use an Intel T265 and a Leap Motion Controller.
The original reference design specified by Leap Motion uses BOE VS035ZSM-NW0 displays.[1]
Versions[edit]
- Release 1 - internal release[2]
- Release 2 - first public open-source release[2]
- Release 3[2]
- Release 3.1[2]
- Release 3.2[2]
- Deck X[2]
- Northstar Next[2]
History[edit]
Prototype reflectors were 3D printed using VeroClear resin.[3]
A secondary set of reflectors, with optical grade reflection, were produced using diamond turning from a block of acrylic material.[3] The secondary set of reflectors were coated with a thin layer of silver to make them reflect 50% of light and allow through 50% of light.[3]
Software[edit]
How to build[edit]
A North Star headset can be built by selecting the right displays and driver board.
Calibration is one of the key steps. Calibration can be done with a calibration rig.
Building with support for hand tracking is not recommended.
