Weaknesses and Speculation
The high cost of optical tracking systems has made this a limited area of research, although with inexpensive CMOS cameras this is becoming more viable and will likely be replacing radar and other lower resolution technologies in the near future.
Leveraging the millions of cameras being developed for Cell Phones, Web Cams, and other applications, CMOS cameras will likely win in short range applications due to costs, even though the visible wavelengths are less optimal.

Famous quotes containing the words weaknesses and, weaknesses and/or speculation:
“Men are much more unwilling to have their weaknesses and their imperfections known, than their crimes; and, if you hint to a man that you think him silly, ignorant or even ill-bred or awkward, he will hate you more and longer than it you tell him plainly that you think him a rogue.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Delicious essence! how refreshing art thou to nature! how strongly are all its powers and all its weaknesses on thy side! how sweetly dost thou mix with the blood, and help it through the most difficult and tortuous passages to the heart!”
—Laurence Sterne (1713–1768)
“Many expressions in the New Testament come naturally to the lips of all Protestants, and it furnishes the most pregnant and practical texts. There is no harmless dreaming, no wise speculation in it, but everywhere a substratum of good sense. It never reflects, but it repents. There is no poetry in it, we may say, nothing regarded in the light of beauty merely, but moral truth is its object. All mortals are convicted by its conscience.”
—Henry David Thoreau (1817–1862)
