===== Room measurement =====

Room measurement makes it possible to reliably measure a room with any corners and edges in MR with a high degree of accuracy. The measuring accuracy is approx. 4 mm over 5 metres and can be increased to 2 mm over up to 50 metres by using a laser measuring device.

==== Requirements ====

For measuring you need:
  * The visualiser product 'Floor Covering Editor'
  * A room that is normally lit
  * A VR headset (Meta Quest 3 or 3s), see [[en:requirements#Hardware]]
  * The Logitech MX Ink Controller (see [[en:pen-controller]] )
  * Optional for millimetre-precise measurement: a [[en:laser-measure-device]]

==== measure a room ====

This is how you measure a room:
  - Make sure you can comfortably reach every corner of the room with the pen in your hand
  - Open the visualiser product 'Floor Covering Editor' in your headset browser
  - Take the left standard controller in your left hand and the Logitech MX Ink controller in your right hand
  - //Note: The right standard controller must remain close to you (e.g. in the same room).//
  - Start the room measurement by clicking on ''Start now'' in the tool area on the right-hand side
  - Select the 'AR' item in the screen dialogue that opens
  - Now go to any corner of the room
  - Hold the tip of the pen in a corner of the room and press the back button on the pen to set a measurement point
  - Go clockwise or anti-clockwise to the next corner and set another measuring point
  - Continue in the selected direction until you have marked all corners of the room with a measuring point.

While you are setting the measuring points, you will see a translucent red area on the floor. This is the area to which you can assign a floor covering (a texture) using the floor covering editor, for example.
