Thirty-three hours of videotape collected in a 1993 pilot study were quantified, via a video
translation software application, to obtain left and right hand activity data of four children of
farmworkers. Reported here are the children's contact duration and frequency for each
object in their environment, duration spent in each location and activity exertion level, and
frequency distributions of object contact durations. The pilot study provided valuable
information for evaluating and improving videotaping and videotape translation …
