The AR+ mode allows you to place annotations in the live stream of the mobile user that stays in place despite movement in the room or change of perspective.

Step 1: To start the scanning process, enter the AR+ mode (6) (see "How can I start the AR+ Mode on Android sessions?") and follow the instructions on your screen displayed in Fig. 23. 

  • The required movement is similar to trying to see the hologram on a banknote.

  • As soon as the virtual blue grid appears on your screen, 3D annotations can be placed.

  • Please make sure to scan the entire surface, where annotations are to be placed (e.g., an entire machine), upfront, so that it is fully covered with the virtual grid. If you scan and annotate part by part, annotations may be slightly displaced. Detailed scanning thus increases the accuracy.

  • For this function to work as precisely as possible, you have to move the camera of your mobile device to properly scan the entire surface, where annotations are to be placed. The scanning process was successful once a virtual grid appears.

Step 2: You can annotate with 2D freehand drawings (2) in different colors and stroke widths, (see fig. 24 below.) (1) 


Step 3: An additional feature available exclusively in AR+ mode is the placement of straight (3) or rotating (5) 3D arrows. 

  • The direction of the arrow is defined via the respective drop-down menu.

  • The arrow is placed upon a click on the designated position on the grid.

Step 4: Individual 3D annotations can still be moved, scaled, or deleted later on using the scale icon. (6)

Step 5: This manipulation can be blocked by activating the lock symbol. (7)

Step 6: To undo or repeat the latest steps, please use the arrow keys on the right edge of the screen. (10)

  • To delete all annotations at once, click on the trash icon. (10)

Step 7: The flash is still available in AR+ mode. (8)

Step 8: The speaker icon (9) allows you to mute and thus control the incoming audio streams.

Step 9: The microphone icon (9) allows you to mute yourself and thus control the transmission of your audio stream.

Step 10: By using the ruler (9), you can measure distances in the live stream.
