The Logitech Zero Touch is designed to give you full hands-free access to your Android phone whilst driving.
Being able to dictate Whatsapp messages or say who to call is invaluable to those who can not type and it even has Alexa built-in! So you can control all your Alexa enabled Smart-Home devices from your phone, either inside your home or if you have mobile data from anywhere in the world!
The only problem is you have to wave your hand in front of the camera to activate it. I will have a look around and see if there is a way around this as it's only recently that I have been able to do this myself.
