App Name: AirSketch ($9.99)
Trial Version: AirSketch Lite (Free - limited functionality)

Contributor(s): Christopher Mong

Developer's Description

Turn your iPad into a wireless whiteboard! Annotate PDF documents and images live.

You can now project PDF documents (such as exported PowerPoint or Keynote decks) to a computer on the same local network, then annotate them in real time, all from your iPad.

Air Sketch is great for presentations in the boardroom, classroom, or on the go. Just fire up Air Sketch on the iPad and open the specified URL from any HTML-5 compatible browser on the local network. Your photos and drawings show up natively in the browser. There's no additional client software to install, or services to subscribe to.

No longer be tethered to the podium! Connect your laptop to a projector to present and draw from your iPad as you walk around the room. You can also easily pass your iPad around to allow others to contribute.

Incorporate the iPad into your desktop-based workflow: Record videos of your live Air Sketch drawings, or share them live with remote colleagues via any online meeting or desktop sharing software (such as iChat or WebEx).

Educational Uses

Assuming you have wireless connectivity and a separate computer attached to a projector, AirSketch gives you the option to project a whiteboard (Lite version's only function), images, or a PDF and annotate them in real time.  For presentations, AirSketch will recognize slides turned into PDF and allow you to advance them remotely, though there will not be any animation, sounds, or movies stored within the PDF.

Presentations made using AirSketch are broadcast to the local network only, and you should try it out in the location you will be presenting in before the time of your presentation to make sure everything works correctly.  Because it is only for the local network, it cannot be simply shared with those on outside networks without other screen sharing software running on the local computer.  However, since AirSketch does not rely on a 3rd party website for broadcast, you do not have to worry about that website working correctly or whether, sometime in the future, that company will stop hosting presentations made using the app.

Tips and Tricks

  • Firefox, Safari, or Chrome should be used for optimal performance.  Hitting F11 on a PC will put the browser into full-screen mode to optimize presentation space.
  • Using AirSketch with a presentation is a good way to untether yourself from the front podium and also emphasize key points on a presentation slide.  Even with a stylus, though, writing readable text on-the-fly can be more of a problem.  Fitting hand-written text onto a slide can be more challenging than you would initially think, so make sure to practice this a bit to better understand the pros/cons of this application.
