Afterglow System Lets You Doodle On PowerPoint Presentations With A Laser Pointer
By Andrew Liszewski
Now here’s a clever idea. Afterglow is a simple system allowing you to annotate a PowerPoint presentation, or other projected imagery, with a standard laser pointer. It uses a USB camera (connected to the PC running the presentation) to track the motion of the laser dot, and the camera doesn’t even have to be setup near the projector since the Afterglow software can compensate for geometric distortion. The system even allows the laser pointer to control the cursor making it function like a mouse, so you don’t need access to the PC feeding the projector or a separate remote for controlling your presentation.
In fact, were it not for the $1,980 price tag, I would have said this is a must-have addition to any board or conference room.
