(red outline is stable on face image from camera)\ Make sure you have sufficient lighting on the user’s face, this will help with face detection. ::: :::faq When I run the UE application, the picture is displayed, but I can't see it in 3D The display scale of Spatial Reality Display may not be 100%, Please refer to [connecting-sr-display-to-pc](/en/Products/Developer-Spatial-Reality-display/en/develop/Setup/SetupSRDisplay.html#pc-env) ::: :::faq Is there a touch-screen version that would allow for an interactive demo? Due to the stereoscopic image created, the viewer will not be interacting with the screen but with a 3D object suspended in space. Due to this “touch-screen” is not available. ::: :::faq 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 [Spatial Reality Display Settings application](/en/Products/Developer-Spatial-Reality-display/en/develop/Setup/spatial-reality-display-settings)) ::: :::faq Any best practices for using Leap Motion device with the Spatial Reality Display? This will depend on the content creator, please follow the content creator’s directions for best interaction experience. ::: :::faq On a laptop, when the application is run, the application exits without anything appearing on the Spatial Reality Display. The GPU may not be set correctly. If you set "Preferred graphics processor" to "High-performance NVIDIA processor" in "Manage 3D settings" from the "NVIDIA Control Panel", the application is likely to run correctly. ::: ## Development Frequently asked questions and answers can be found on the following developer sites: Go to Development Assets > FAQ. :::devlink [Spatial Reality Display Developer Site](/en/Products/Developer-Spatial-Reality-display/) Supported languages: Japanese, English, Simplified Chinese ::: ## And more If you need more information, refer to the following website and article. - for Japan: https://www.sony.jp/support/spatial-reality-display
