A simple integrated circuit device for measuring distances traveled and determining speed in open-field environments.
An easily constructed and inexpensive device for measuring distance and determining mean speed, which utilizes an integrated circuit (IC) photosensor system, is described. It was designed for evaluating activity of small animals in open-field environments, being used in conjunction with a video-recording system. The horizontal locomotor path of the animal is manually tracked directly from the video monitor image or from a tracing made of the image.
