Quantitative behavioral observation can add a great deal of depth to anthropologi-cal research. The development of laptops, handheld computers, and observational software has given researchers enhanced flexibility in sampling strategies and assis-tance in training and establishing reliability; it has also greatly reduced the amount of time required for data entry. With technological advances, more researchers should be able to incorporate quantitative behavioral analysis into their projects. Although computer-assisted data collection offers many advantages, it is not without pitfalls and limitations. One of the primary disadvantages is the potential loss of data resulting from battery failure, computer error, or operator error. This article reviews the basic elements of observational data collection and considers the advan-tages and disadvantages of computer-assisted quantitative observational data col-lection for human field research, with a focus on The Observer software and associated hardware from Noldus Informational Technology ( © 1995–2003)
