Air mouse presenters
Remotes that move the cursor when you move your hand, so the laptop can stay across the room.
Switch on the air mouse and the remote becomes a pointer for the real cursor: click a video, open a link, switch windows. On a TV or LCD panel that is also how you point, since a light does not show there.
Choose the rechargeable remote for weeks between charges and a choice of colours, or the AAA model when you would rather carry spare cells than a cable.
The 2 models on the Air mouse presenters shelf belong to DINOSTRIKE docks and remotes, and each carries its box list on its own page.
Press the last key. The remote then moves the cursor as you move your hand, and the same key switches it off again.
Rechargeable if you present often: it charges in about three hours and lasts weeks. AAA if you would rather keep spare cells in a bag than a cable.
