    The robot in itself is still not AR. Now, if you as a human being can see what the robot is seeing and identifying (overlaid on the actual scene) then that is AR.

    Definition of AUGMENTED REALITY

    Cozmo robots do AR:

    When the explore mode is off and you no longer have the display, it's still doing object recognition, but it's no longer AR.

    But yes I agree HUD != AR and likewise AR != HUD but there can exist an AR HUD.

    It would appear to me, someone without a scientific/academic background in AR or AI, that some here are using AR to describe something that sounds like AI.
    Either or both could be part of a HUD system, or AI could be part of AR, but one is not the same as the other.

    It seems like we all can agree on that someone has misunderstood the meaning of some technological designations. :)

    To me AR augments the reality you see so you need glasses or a screen to view "reality" and have something projected into it that can interact with what you see. The difference between a HUD and AR is that AR can interact with things you see. For example, you look at a table and a truck will appear to drive on it and bounce over the pencil on it and get blocked by a book. A HUD would just overlay info on your field of view.

    You can't really contrast against a HUD because a HUD can have AR. You might clarify and say a dumb HUD.

    Example: This is a HUD with AR
    [​IMG]

    Due to the simple fact that it has highlighted the other plane makes it an AR HUD instead of a dumb HUD because the information is augmenting the real object. It's not the prettiest thing in the world, but it's still AR.

    Modern AR HUDs like the Microsoft HoloLens do some cool things such as with 3D environment mapping (not necessarily required for AR)

    To me, you need more than just the ability to identify and circle an object for AR. Smart HUD is fine but that's still not AR to me. There needs to be interaction and 3D ability.

    We are talking about a fine line here that in the end won't matter much.

    I think a "smart HUD" is very likely with advanced features like identifying threats (cars, objects,people) and things like that.

    What you think is AR and what is, by definition, AR might be two slightly different things.

    AR would be any augmentation of what you would see normally. So, it could well be as simple as a circle or some lines.

    My thinking is that, if there is a HUD, you'll only get AR (if they even have it) if you get the EAP, that way they would be able to use the additional cameras and sensors to augment with. Either way, we'll have a good idea if they announce a HUD for the Model S and X first.

    HUD's were around long before the term "argumented reality", or any AR tech was. That's why I say they are different.

    You can have a HUD with or without AR.

    You just contradicted yourself. Is a simple HUD with lines AR or not?

    Here is the test-

    If Tesla puts a HUD in the 3 that just displays speed, state of charge charge and turn signals and markets that as Augmented Reality will people be mad?

    Absolutely, IMO.

    Does anyone else think a HUD is a very complicated way to solve a simple problem?

    I think they are very useful for certain things and a distraction for many others.

    If it is just to replace what we normally find behind the steering-wheel, then yes, I agree.

    If on the other hand, they use it to add real meaningfull AR to the display I think it is the right tool for the job.

    No I didn't. A HUD with anything added to it would be a HUD with AR. Even if it was just a box around cars close to you, or a flashing icon above a speed limit sign.

    I wouldn't be mad but it sure would be misleading.

    HUDs aren't complicated, adding AR and other things might make it complicated. And the problem isn't necessarily simple either. The goal is to get the right amount of needed information to the driver at the right time in such a way that it is as safe as possible. A HUD is one way to do that, as is a regular dashboard, or a center mounted, 15" diagonal, landscape oriented screen.

    That's were we will have to agree to disagree.:)

    The addition of a simple box or a flashing icon would not be enough.

    Yes, it would augment reality. HUD is cheaper than a traditional dash. HUD+AR lets the driver see what the car is paying attention to and acting on, and allows the driver to keep his/her eyes on the road.

    I know what a HUD does, that is not the question. Do you think a simple HUD is AR? If so why do you say HUD + AR?

    I notice HUD's are not in there;). And they were around before the term AR was coined.
