AirPlay

The following post from Britain refers to the release of IOS 5.0 and Apple TV Version 2. Combined with a HDTV, Apple TV will eliminate the projector, projector cable, and interactive whiteboard in the classroom if you have an iPad. I see this as a very promising advance since the iPad doesn't work as well tethered to a large projector cable with a connector that is designed to pull out with any pressure our weight. Here is the post by Fraser Speirs:

AirPlay Mirroring

As you know, I've been looking at HDTVs and AppleTV as replacements for projectors and Interactive Whiteboards for some time (see here and here). Well, yesterday, that arrangement just got a whole lot better. Apple announced that it will soon be possible to wirelessly mirror your iPad to an HDTV with an AppleTV attached.

This is significant for classroom design. One of the beauties of AirPlay is that anyone can connect to the display from anywhere on the network. It has been available for a while now for video and photos but to be able to mirror your entire iPad screen to a wall-mounted display is significantly more powerful.

It gives you wireless Keynote presentations from anywhere. It gives you Penultimate in your hand without the cable tying you to the front. It puts any web resource that anyone found useful on your classroom wall. It lets you have any child take over the display to show their work without "standing up in front of the class" to do so.

I've been talking about "Keynote over AirPlay" for a while now as something that teachers would generally find useful. We just got that, plus 64,999 other apps "over AirPlay".
