WiFi Remote

WifiRemote [Appstore link] requires a small but free server application to be running on the desktop computer it should be paired to.
Pairing is easy, and Wifi remote is easy to use. It comes with several fix button layouts, an app launcher, a trackpad with buttons, a virtual mouse with three buttons and mouse pointer control by tilting (accelerometer controlled) and one (unfortunately ONLY ONE) screen that can be configured by the user. Up to 18 buttons can be configured with three different colors, text, and a keyboard shortcut. The set-up of the key is easy and straightforward. And, luckily, it is the only solution discussed here in this block which I could configure to work really great with Power Point 2004 on a Mac - other solutions work only with Office 2008, or the Windows version, or only support navigation in presentation mode, but not starting and finishing presentations, or switch to the "sort slides" view in power point. The screenshot with the red, green and blue buttons and button text in German has been set up by me and does NOT come with Wifi remote.

Wifi remote does not show a live screen, and is maybe a bit short of eye candy, but it works. Feature requests for the next version are

(1) on the user screen do not show buttons that have no keyboard shortcut associated, i.e. are not used.

(2) more user screens, please

(3) larger buttons as an option on a user screen, or mixing large and small buttons as needed

(4) web based user screen layout exchange

(5) use fotos from foto roll for user screens. The user could then define "hot" areas (buttons) and finally associate keyboard shortcuts with these hot areas.

A lite version is also available, with limited features.
