Alana Elliott Humans are complex organisms that possess well-balanced sensorimotor systems, with counterbalanced receptor and effector systems that enable them to sense psychomotor data and act on it using complex motor systems. Likewise, humans have reasonably keen aural perception, allowing them to hear a large range of sounds. Those sounds can be replicated or at least responded to orally by forcing air through the diaphragm, palette, and lips to create an infinite variety of sounds. However, our most sophisticated sensory system, vision, where the largest amount and variety of data are received by humans, has no counterposing effector system. We receive massive amounts visual input, but we have no output mechanism for visually representing ideas, except in mental images and dreams, which unfortunately cannot be easily shared with others. Visual images are powerful mediators of meaning making. Many of us often have to visualize something before we can make sense of it, but sharing those images is problematic. Therefore, according to Hermann Maurer, humans need visual prostheses for helping them to visualize ideas and to share those images with others.
