I found the Android Bluetooth Remote on the Android Marketplace, and decided to give it a try, as I have bluetooth on my computers and thought it’d be a fun program. It claims to be a remote control for your computer, and it fulfilled that claim beyond my expectations.
It acts as a remote control for most media programs, with start/stop/next/previous and volume buttons. It also lets you lock your computer, and handle shutting down and restarting.
Now, the coolest feature is that it lets you use your Android phone as a keyboard and mouse for your computer. If you have a phone with a physical keyboard (like the droid) you can use the screen as a touchpad and the keyboard as a keyboard at the same time, otherwise you have to bounce between the two applications. It’s pretty responsive and very quick at updating on the screen. There’s a fraction of a second of lag on the keyboard, but it’s not too noticeable.
It connects to your computer via bluetooth, and requires a small helper application installed on the computer. It’s pretty useful if you want to control a computer that’s not easily accessible or watch movies across the room.
