How do you set up Leap Motion Controller with the PC running Spatial Riality Display?
Install the Leap Motion drivers on the PC following the instructions on Leap Motion’s website. \
Additionally, the content creator must have incorporated gesture control into their design for this to work with the Spatial Reality Display.
If you notice that some 3D image is not stable, there could be some interference between Leap Motion Controller’s IR light and the Spatial Reality Display’s camera,
In this case we recommend adding an IR cut filter or film (with transmittance level of approx. 0.1%@850nm, or less)
in front of the Spatial Reality Display’s camera, to minimize interference.
When using filter over the camera, control room lighting not too dark for eye detection. (Please refer to [Spatical Reality Display Settings application](/Products/Developer-Spatial-Reality-display/en/develop/Setup/spatial-reality-display-settings))
