 For a user to interact with a computer system (desktop, mobile, \AR, etc.), they first perceive the state of the system and then acts upon it through an input device \cite[p.145]{laviolajr20173d}.
 Such input devices form an input \emph{\UI} that captures and translates user's actions to the computer.
