Appear.in is a free video conferencing service that I recently learned about from Ana Maria Menezes. Appear.in allows you to create a video conference room without registering for any kind of account. Your Appear.in video conference room can accommodate up to eight people.
To create your room just go to Appear.in, pick a room name, and grant Appear.in access to your webcam. Appear.in will give you a URL for your conference room. Share that URL with the people that you want to join you in your video conference. If you want to save your room to re-use on multiple occasions, you can enter your email address and choose a password to lock and save your room. Locking your Appear.in room prevents people from using it when you're not in it.
Applications for Education
Appear.in could be a great tool for hosting online tutoring sessions, bringing guest speakers into your classroom, or hosting online meetings with colleagues. The registration-free and installation-free aspect of Appear.in makes it easy to get your web conference started quickly.
