iPad as a Document Camera

ipad-documentcamsYou’ve probably noticed that the 5 megapixel camera on the back of your iPad takes some pretty good pictures and video.  You’ve also probably noticed that sometimes it’s tough to hold the iPad at the right angle and keep it still when using the camera.

The music department has taken this problem a step further, and in the process, has found another innovative use for the iPads.   Assistant Professor of Music Theory, Dr. Peter Purin, is considering using one of the new iPad gadgets seen in the pics above to replace some of the aging and broken document cameras in the music classrooms.  Stand-alone document cameras can cost $1,000 and more and are often not easily portable.

These devices, such as the two referenced below, are inexpensive and have multiple uses that take advantage of the portability and the high quality imaging available in today’s mobile devices. The image from the iPad attached to the document camera can be sent to the projector via VGA adapter cable, or via AirPlay through the Apple TV device that is installed in many classrooms.  They can typically be used with any mobile device that has a camera, not just an iPad, as long as you have a method to send the video to the projector.

Apple TVs in the Classroom

Wireless projection is now possible in almost
half of the OBU main campus classrooms.

The sound signal is also sent to the projection speakers.  It uses Apple’s “Airplay” protocol to connect wirelessly to other Apple products.  If you have an Apple device that is on the same wireless network as the Apple TV device (the employee network), you can mirror your screen onto the projector and show presentations, show web sites, show videos, demonstrate apps and other software, etc.
