An air mouse is a type of wireless mouse/remote that lets you control a cursor by moving your hand in the air, instead of sliding a mouse on a table.
How it works
• It has motion sensors (like a gyroscope) inside
• When you move your hand, it detects the motion
• The cursor on your screen moves accordingly
So it’s similar to pointing a TV remote or Wii controller at the screen.
Where it’s used
• Smart TVs / Android TV boxes
• Computers & laptops
• Projectors or presentations
• Gaming or media control
Advantages
• No surface needed (works in the air)
• Easier for navigating TV menus
• combines remote + mouse + keyboard in one device
