==Overview== | ==Overview== | ||
Project North Star | Project North Star represented Leap Motion's vision for making high-quality AR experiences accessible to developers and researchers. The headset features dual 1600×1440 displays running at 120 [[frames per second]], providing a combined field of view exceeding 100 degrees<ref name="announcement"/>. This was significantly wider than contemporary AR headsets like [[Microsoft HoloLens]] (approximately 40° FOV) and [[Magic Leap One]] (approximately 55° FOV). | ||
The design philosophy emphasized openness and accessibility, with most components being either [[3D printable]] or available off-the-shelf. Leap Motion estimated that the headset could be produced for under $100 at scale<ref name="announcement"/>, though individual DIY builds typically cost between $350-600 due to smaller component quantities<ref name="buildcost">{{cite web|url=https://www.smart-prototyping.com/blog/Building-Project-North-Star|title=Building Project North Star|author=Noah Zerkin|website=Smart Prototyping|accessdate=June 26, 2025}}</ref>. | The design philosophy emphasized openness and accessibility, with most components being either [[3D printable]] or available off-the-shelf.
