These are broad groups that can be divided further by echolocation design and foraging strategy. In the domain of vision, two main classes of such sensory substitution devices have been constructed: echolocation devices and tactile visual substitution devices. The feeding behaviour of insectivorous bats: echolocation, foraging strategies, and resource partitioning. We recorded the echolocation calls of passing bats for 10 min per 30-min sampling interval. The camera-like eye is a classic example, but so are such features as hearing, echolocation and a sense of smell. Echolocation devices provide auditory signals which depend on the direction, distance, size, and surface texture of nearby objects, but they provide no detailed shape information. The eye provides the premier example, although just the same arguments could be put forward for any of the other sensory systems, such as olfaction, audition, echolocation and electro-reception. Maternal genes could benefit from echolocation imagery if it allowed for more reliable assessments of information in an aquatic environment where visual assessments are error-prone. Finally, the book only weakly relies on psychoacoustics for its argument, except for basic information about binaural localisation which is generally grouped under the heading of echolocation. However, with more understanding of the physics of echolocation, considerable research has been conducted in extracting more information from the ultrasonic echoes rather than just arrival times from single transducers.
