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:
“Never yield to that temptation, which, to most young men, is very strong, of exposing other people’s weaknesses and infirmities, for the sake either of diverting the company, or of showing your own superiority. You may get the laugh on your side by it for the present; but you will make enemies by it for ever; and even those who laugh with you then, will, upon reflection, fear, and consequently hate you.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“To “give style” to one’s character—a rare and noble art! Those practice it who compass all that their natures present as strengths and weaknesses and then fit them into an artistic plan until every one appears as art and reason and even weakness enchants the eye.”
—Friedrich Nietzsche (1844–1900)
“When speculation has done its worst, two and two still make four.”
—Samuel Johnson (1709–1784)
