Free webcams online
Webcams have been used for augmented reality experiences online.
One such function has the webcam act as a "magic mirror" to allow an online shopper to view a virtual item on themselves.
The main ideas for Yawcam are to keep it simple and easy to use but to include all the usual features.
By removing the IR filter of the webcam, IR LEDs can be used, which has the advantage of being invisible to the naked eye, removing a distraction from the user.
Track IR is a commercial version of this technology.
They have also become a source of security and privacy issues, as some built-in webcams can be remotely activated by spyware.
The most popular use of webcams is the establishment of video links, permitting computers to act as videophones or videoconference stations.
