If your student is unable to attend their lesson then we have recently added the capability to perform a virtual lesson using several different video sharing solutions (Skype, Facebook Messenger or Google Duo among others)
The optimal setup is so that video captures the student’s hands and the piano keys from over their shoulder while still being in a position that the student is able to turn to see their teacher when receiving their feedback.
We have found a couple of inexpensive solutions that can be delivered to your door relatively quickly to facilitate this setup.
Camera position
Try to position camera so that student is able to turn to see the teacher when they are receiving instruction.
Ideal view from camera
Try to frame hands and keyboard within the view
