Cued speech is a visual system of communication used with and among deaf or hard-of-hearing people. It is a phonemic-based system which makes traditionally spoken languages accessible by using a small number of handshapes, known as cues (representing consonants), in different locations near the mouth (representing vowels) to convey spoken language in a visual format.
Manual communication systems use articulation of the hands (hand signs, gestures, etc.) to mediate a message between persons. Being expressed manually, they are received visually and sometimes tactually. When it is the primary form of communication, it may be enhanced by body language and facial expressions.
The training protocol is based on the principles of applied behavior analysis. [3] The goal of PECS is spontaneous and functional communication. [3] The PECS teaching protocol is based on B. F. Skinner's book, Verbal Behavior, such that functional verbal operants are systematically taught using prompting and reinforcement strategies that will lead to independent communication.
Picture Communication Exchange System (PECS) is a commonly used low-tech communication system that teach individuals how to request, comment, and answer questions through the use of line drawings known as Picture Communication Symbols (PCS). Symbols are placed in fixed position on the screen which allow users to develop motor patterns ...
The visual system can detect motion both using a simple mechanism based on information from multiple clusters of neurons as well as by aggregate through by integrating multiple cues including contrast, form, and texture. One major source of visual information when determining self-motion is optic flow. Optic flow not only indicates whether an ...
Intention to touch: A nonverbal communication haptic code or cue is the intention behind it. Reaching your hand across the table to a somewhat unknown person is used as a way to show readiness to touch. Kissing: Moving in concert by turning heads to allow for the lips to touch is the final part of the fourth stage of courtship, the kiss.

The second group of multimodal systems presents users with multimedia displays and multimodal output, primarily in the form of visual and auditory cues. Interface designers have also started to make use of other modalities, such as touch and olfaction. Proposed benefits of multimodal output system include synergy and redundancy.
