PortaNum, a software vision aid

copies d'écran Portanum

PortaNum is a software vision aid specially designed to facilitate reading of distant documents (board, video-projection screen ...). Your computer is connected to a good quality video-camera, or a camcorder filming what you do not read, and the software zooms in and applies image processing to suit your vision (inversion, false color, improved contrast, brightness, sharpness  ...). It allows you to snapshot the image. You can also take notes while watching the images displayed.

In classroom, you can connect to an Interactive Whiteboard.

You can also use it as a video-magnifier, for paper documents on your desktop. For this application, a simple webcam can be used.

Finally, PortaNum can be used to watch pre-recorded images, including scanned documents.
