Quick Assist, is a simple and quick way to take remote control of another person's Windows 10 based device. I find it's easier to walk a tech-neophyte through setting this up rather than the other platforms. I still like to use a video platform such as Zoom for my eye-gaze users, so I can see their level of engagement, affect, and even make suggestions about positioning. Together, they make for a robust tool set. It's free, and built into all Windows 10 computers. Keep in mind, your client's device will need to be "unlocked" for any teletherapy hosted right on the device.
