Does the usb have to be plugged into my pc or xan i plug it into the back of my tv

You could try bc some smart tv with internet ready has usb port where you could plug a wireless mouse and keyboard. This overlay is just like a giant trackpad or mouse that navigate the entire tv screen, it senses the exact location of your finger like a gps.
