It's a common staple of science-fiction films (e.g *The Terminator* or *Robocop*) to have a [POV shot from a robot or cyborg's perspective with a HUD being used to observe it's surroundings](http://tvtropes.org/pmwiki/pmwiki.php/Main/RoboCam). This can be handwaved by the fact this is a convenient way for filmmakers to use visual imagery to make a robot's train of thought mind clear to the audience very simply and quickly.

Would a robot need a HUD to act as some sort of decision-making mechanism? And if so, what sort of circumstances would make a robot need to use a HUD when studying it's environment?
