It is easy to use, and a great tool to have.By placing the laptop computer between the talent and the camera, the talent can read text from the top of the laptop screen and still appear to be looking at the camera if the camera is far enough back using a long lens. Trial and error is the key to getting a natural look to this process but the further the camera is from the subject, the better. If the talent will be controlling their own scrolling then mouse control is the best and if you have long mouse cord, that's even better. There is a built-in function to allow someone else to control the speed by using the keyboard or mouse. Use both if you like. For those traditionalists, Prompt! will also flip the text for use on a half mirror.
