#SHAKEDOWN HAWAII 3DS QR CODE DRIVER#

When the device is rebooted or the driver restarts, the detected QR codes history is cleared.

#SHAKEDOWN HAWAII 3DS QR CODE WINDOWS#

Windows Mixed Reality devices detect QR codes at the system level in the driver.

Note: Higher versions of QR codes will have smaller modules.įor the tradeoff relationship between distance and size of the QR code for optimal detection, see the following graph:Īlways make sure you have enough contrast and a proper border.

The physical size of the QR code should have modules of at least 2/3 pixels.Out of plane should be <= +-45 looking straight on to have better detection. QR codes on curved surfaces aren’t supported.QR detection works with a range of angles += 45 deg to ensure we have proper resolution to detect the code. You can also try micro-QR codes if you want the distance of detection to be longer. The higher the version, the smaller the modules, which can only be detected from a closer position. The detection distance for size increases linearly, but also depends on supported QR version or module size. For a version 1 QR code varying from 10 cm to 25 cm in size, the minimum detection distance is between 0.15 meters and 0.5 meters. For small codes (less than 10 cm along the sides) you must be fairly close. The tracking cameras can only detect a certain level of detail. Distance and angular position from the QR code Moving closer to the code will help offset issues with size. The exact time to detect codes depends not only on the size of the QR codes, but how far away you are from the code. Windows Mixed Reality devices don't work with QR codes with sides smaller than 5 cm.įor QR codes with sides ranging from 5 cm to 10 cm, the device must be fairly close to detect the code. The white background within the QR code can be reduced from 255 downwards. In extreme lighting conditions with bright lighting or dark backdrop, you can try to reduce and adjust contrast which could improve QR code detection rate. Under normal lighting conditions, provide enough contrast for the black/white modules for better performance. QR code detection quality is susceptible to varying illumination and backdrop. The QR spec contains more information about quiet zones. This margin must not contain any printed content and should be four modules (a single black square in the code) wide. To be read correctly, QR codes require a margin around all sides of the code. Tweaked modules, for example: circular modules, reflections, inverted (black/white).īest practices for QR code detection Quiet zones around QR codes.QR Codes 10 - 20 (these may work, but are not guaranteed).The following table lists the supported and unsupported QR code versions: Use the () API to determine whether the feature is supported on the current device.

#SHAKEDOWN HAWAII 3DS QR CODE WINDOWS 10#

QR code tracking with immersive Windows Mixed Reality headsets on desktop PCs is supported on Windows 10 Version 2004 and higher.

How close do I need to be to the QR code to detect it?.If QR code tracking doesn't work in general, what do I do?.How do I prepare Unity with the .QRCodeWatcher?.How do I prepare a UWP to use .QRCodeWatcher?.How do I make the QR Code Tracking Feature work on HoloLens 2 devices?.Distance and angular position from the QR code.For best results going into production, we recommend that you review the best practices section. Once you enable your device's webcam, you'll recognize QR codes in the latest versions of your projects. You can also render holograms in the same location on multiple devices to create a shared experience. With HoloLens 2 and immersive headsets, you can detect QR codes in the environment around the headset, establishing a coordinate system at each code's real-world location.
