An emoticon, short for emotion icon, is a pictorial representation of a facial expression using characters—usually punctuation marks, numbers and letters—to express a person's feelings, mood or reaction, without needing to describe it in detail.
Diver communications are the methods used by divers to communicate with each other or with surface members of the dive team. In professional diving, diver communication is usually between a single working diver and the diving supervisor at the surface control point. This is considered important both for managing the diving work, and as a safety measure for monitoring the condition of the diver. The traditional method of communication was by line signals, but this has been superseded by voice communication, and line signals are now used in emergencies when voice communications have failed. Surface supplied divers often carry a closed circuit video camera on the helmet which allows the surface team to see what the diver is doing and to be involved in inspection tasks. This can also be used to transmit hand signals to the surface if voice communications fails. Underwater slates may be used to write text messages which can be shown to other divers, and there are some dive computers which allow a limited number of pre-programmed text messages to be sent through-water to other divers or surface personnel with compatible equipment.
An emoji is a pictogram, logogram, ideogram, or smiley embedded in text and used in electronic messages and web pages.

The raised fist, or the clenched fist, is a long-standing image of mixed meaning, often a symbol of solidarity, especially with a political movement.

The shaka sign, sometimes known as "hang loose" is a gesture with friendly intent often associated with Hawaii and surf culture. It consists of extending the thumb and smallest finger while holding the three middle fingers curled, and gesturing in salutation while presenting the front or back of the hand; the wrist may be rotated back and forth for emphasis. The shaka sign is similar to the letter Y in the American manual alphabet in American Sign Language or the sign for number six in the Chinese hand counting symbol. The shaka sign should not be confused with the sign of the horns, where the index and pinky fingers are extended and the thumb holds down the middle two fingers.

Chinese number gestures are a method to signify the natural numbers one through ten using one hand. This method may have been developed to bridge the many varieties of Chinese—for example, the numbers 4 and 10 are hard to distinguish in some dialects. Some suggest that it was also used by business people during bargaining when they wish for more privacy in a public place. These gestures are fully integrated into Chinese Sign Language.
The OK gesture, OK sign or ring gesture is a gesture performed by joining the thumb and index finger in a circle, and holding the other fingers straight or relaxed away from the palm.

In other contexts or cultures, similar gestures may have different meanings including those that are negative, offensive, financial, numerical, devotional, political, or purely linguistic.

American Sign Language (ASL), the sign language used by the deaf community throughout most of North America, has a rich vocabulary of terms, which include profanity. Within deaf culture, there is a distinction drawn between signs used to curse versus signs that are used to describe sexual acts. In usage, signs to describe detailed sexual behavior are highly taboo due to their graphic nature. As for the signs themselves, some signs do overlap, but they may also vary according to usage. For example, the sign for "shit" when used to curse is different from the sign for "shit" when used to describe the bodily function or the fecal matter.
Finger-counting, also known as dactylonomy, is the act of counting using one's fingers. There are multiple different systems used across time and between cultures, though many of these have seen a decline in use because of the spread of Arabic numerals.
The manicule, ☛, is a typographic mark with the appearance of a hand with its index finger extending in a pointing gesture. Originally used for handwritten marginal notes, it later came to be used in printed works to draw the reader's attention to important text.

A facepalm is the physical gesture of placing one's hand across one's face, lowering one's face into one's hand or hands or covering or closing one's eyes. The gesture is often exaggerated by giving the motion more force and making a slapping noise when the hand comes in contact with the face. The gesture is found in many cultures as a display of frustration, disappointment, exasperation, embarrassment, horror, shock, surprise, exhaustion, sarcasm, shame, or incredulous disbelief.

Hand gestures are used in regions of Italy and in the Italian language as a form of nonverbal communication and expression. The gestures within the Italian lexicon are dominated by movements of the hands and fingers, but may also include movements of facial features such as eyebrows, the mouth and the cheeks. Theories persist as to the exact origin of hand gestures as a method of communication in Italy, however it is likely that they emerged through necessity as a universal, non-verbal method of communicating across different Italian local languages and dialects. Despite the majority of today's Italian population speaking Italian, hand gestures have persisted as a method of expression to accompany verbal speech in many regions of Italy.
