AR: The issues left behind

Hedley’s article, although a great summary of the progress made in AR does not truly convey the issues of use. One of the biggest down falls for AR, currently, is that sensory feedback to the user is lacking. Although, a lot has been done to try and get input to and from the user (the creation of mice and touch screens; Both Steve Jobs inventions) that combine and provide physical (touch of tool), auditory (clicks), visual (screen illumination), nothing is 100% satisfactory. The “Holodeck” from Star Trek is an example of how feedbacks entertain all senses and provide a full range natural feedback; i.e. you can physical feel the change, hear the change, see the change, and smell the change.

Ipad screens and Microsoft connect modules may provide a link to the computer and bridge the gap in what is reality and how we can understand our surroundings, but lack that basic human need for satisfaction of a response. To elaborate even if physical objects can be manipulated to create change in the presented reality they are not perfect. The objects that are used are generic, such as balls or cubes, and do not provide a universal design for all settings or sensations. Basically, the texture of what is viewed is not necessarily the same as the object being manipulated. To correct for this an infinite amount of objects would have to be stored in order to represent the same object in reality and within an AR system. One solution I believe to this problem may be the use of non-Newtonian or electromagnetic fluids feedback mechanisms that can be altered to many states and textures.

Finally, Hedley’s article seems a little out of date as 3D no longer requires glasses and tough screen interfaces are leaps above what is discussed (Thanks to Apple’s and Steve Jobs’ push for natural interfaces). As a last note, I feel there is also a lack of discussion on digital representation of images in AR and how they can be too cartoony or not real enough.

    Correction: “Holodeck” in Star Trek example may not be truly considered AR. Instead think about the Holo-Graphic Doctor from Star Trek Voyager as AR.
