You can switch the laser pointer mode by pressing the plus (+) and minus (-) volume buttons at the same time.

You can also use vocal commands to change the laser.

• Say: "Hey OrCam, change laser shape"
• Alternatively you can double tap on the trigger button, and after the long beep say: "change laser shape".
  
  There are two laser pointer modes:
  •   “Border/Rectangle” for reading framed text.
  •   “Arrow/Mouse” to read a specific word.
