Presenting, a USB-tethered webcam application for phones and devices running Google Android OS. Your phone has a perfectly good microphone and video camera. Why buy or manufacture a separate USB webcam product to do the same thing? Help save the Earth and save some cash by using USB Webcam for Android.
There are two parts to USB Webcam for Android: One piece is installed on the phone or device via Android Market, and the other piece is installed on the Windows PC. A background process can be started or stopped in Windows, and while the process is running, DirectShow-compatible video chat clients or capture programs can use phone as a camera and/or microphone.
The camera and microphone functions are somewhat independent, this could be named USB Microphone just as easily.
It turns out, most video chat applications require kernel-mode video capture drivers (oops, this one is user-mode) and few applications use DirectShow at all for audio capture. So currently, besides specific capture applications, USB Webcam is probably most useful for Skype.
