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:
“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)
“What is called an acute knowledge of human nature is mostly nothing but the observer’s own weaknesses reflected back from others.”
—G.C. (Georg Christoph)
“When speculation has done its worst, two and two still make four.”
—Samuel Johnson (1709–1784)
