<p>Hello all, this is my first post. I have been readin posts here for a while and finally decided to start posting. I like many applied to NASA sharp, crossing my fingers to get in. I had a little trouble with the essay cus i wasnt sure wat they wanted and might have taken the wrong direction, im still hoping that they might see my sincere interest in in math and sience. I have included my essay, tell me if you think that it completely destroys my chances of getting into NASA sharp, something i have truly been praying for like many of you...</p>
<p>Here is my essay</p>
<pre><code> Technology is shaping the world. It is fueling modern industry, and has become integrated into every aspect of our lives. It has been rapidly progressing for the past couple of decades, and the advances of the future will tackle new frontiers. There are many fascinating things one could discuss concerning the effects of technology on the future. Because of my own bias, and my inability to address all of these, I will focus on the advances in computers, particularly Augmented Reality.
In AR, one's perception of the outside world is supplemented by digital data generated from a computer. The data is shown on a transparent display known as a Head Mounted Display. Information is superimposed on its proper location in the real world. Thus, as one turns his head the information is constantly being modified to suit its correct location. This creates seamless coexistence of real and digital images. A precise tracking system is required because an AR system must locate a user in reference to his environment. This is the biggest challenge facing researchers. GPS is the only available technology for outdoors, but its margin of error is too great. More accurate systems, such as differential GPS and real time kinematics GPS, are being worked with.
AR prototypes have already been created in many universities such as Columbia, MIT, and Oxford. As mobile processing gets faster, tracking becomes more precise, and as cost is reduced, AR will flourish. AR will have a profound effect on how we view the world. With AR, a surgeon can view data such as organ location overlaid on a patient. A mechanic can receive systematic assistance while repairing an engine. AR has an application in virtually every field. Eventually, AR will become commonplace. It will redefine the way computers are used.
