Expanding from “document cameras” that project printed materials or desktop experiments, AVer introduces cameras that stream to an iPad as a presentation or recording device
The overhead projector is being reincarnated as an iPad app.
The traditional overhead projector, a device for projecting lecture transparencies on a screen, has been gone from most classrooms for a while now, replaced by “document cameras” that meet the continuing need to occasionally project images from a book, magazine, map or drawing not already in a digital format. Despite the “document” name, these devices can also be handy for projecting other images, such as close-ups from a science experiment, onto a digital display.
Now one of the leading makers of classroom document cameras is getting the iPad bug. The TabCam, from AVer Information Inc., is a document camera, mounted on a flexible arm and made mobile with the addition of wireless networking and a rechargeable battery. While it can be used with a Mac or a PC, the exciting part of the product is its connection to an accompanying iPad app that allows an instructor to view and annotate the video from the camera, either projecting it live or recording it to share with students later.
“The difference is that both pieces are mobile,” said Kris Rangarajan, marketing director at AVer. That means the camera can be used anywhere in the classroom. Students can use it to share video of something they are drawing at their desk or a chemistry experiment they are performing at the lab sink, and the teacher can interact with that video. The TabCam app supports fingertip drawing on the screen, allowing the instructor to circle images that deserve particular attention. There is also a blackboard function, allowing the instructor to draw or write messages on the iPad and have them displayed against a blank background.
The system is iPad-specific for now, although AVer plans to release an Android version later this year, Rangarajan said. “We wanted to tackle the iPad first. Getting the recording function, the live streaming of video and the annotations right was a pretty serious undertaking, and we wanted to accomplish that first.” AVer also sees an opportunity in appealing to the many teachers and school systems that are deploying iPads en masse and need to find effective ways to use them.
AVer is primarily targeting iPad use in K-12 education.
