When a student is trying EagleEyes or CameraMouse we often are asked by the school system, “How much money is this really going to cost us?” And rightly so. To begin to answer this question we recently looked in detail at the total education costs for two students, one who uses EagleEyes and one who uses CameraMouse. With the help of their local school systems we compiled all the year-by-year financial costs since they began using the technologies and best estimates of what the costs would have been had they not used the technologies. We found that for these two students the technologies more than paid for themselves financially. The paper can be downloaded at www.cs.bc.edu/~gips/costs.pdf or from www.eagleeyes.org.
