Face-to-face interaction in the context of "Photo identification"

A neighbourhood (Commonwealth English) or neighborhood (American English) is a geographically localized community within a larger town, city, suburb or rural area, sometimes consisting of a single street and the buildings lining it. Neighbourhoods are often social communities with considerable face-to-face interaction among members. Researchers have not agreed on an exact definition, but the following may serve as a starting point: "Neighbourhood is generally defined spatially as a specific geographic area and functionally as a set of social networks. Neighbourhoods, then, are the spatial units in which face-to-face social interactions occur—the personal settings and situations where residents seek to realise common values, socialise youth, and maintain effective social control."

Interpersonal communication is an exchange of information between two or more people. It is also an area of research that seeks to understand how humans use verbal and nonverbal cues to accomplish several personal and relational goals. Communication includes utilizing communication skills within one's surroundings, including physical and psychological spaces. It is essential to see the visual/nonverbal and verbal cues regarding the physical spaces. In the psychological spaces, self-awareness and awareness of the emotions, cultures, and things that are not seen are also significant when communicating.

Interpersonal communication research addresses at least six categories of inquiry: 1) how humans adjust and adapt their verbal communication and nonverbal communication during face-to-face communication; 2) how messages are produced; 3) how uncertainty influences behavior and information-management strategies; 4) deceptive communication; 5) relational dialectics; and 6) social interactions that are mediated by technology.

Open society (French: société ouverte) is a term coined by French philosopher Henri Bergson in 1932, and describes a dynamic system inclined to moral universalism. Bergson contrasted an open society with what he called a closed society, a closed system of law, morality or religion. Bergson suggests that if all traces of civilization were to disappear, the instincts of the closed society for including or excluding others would remain.

The idea of an open society was further developed during World War II by the Austrian-born Jewish philosopher Karl Popper. Popper saw it as part of a historical continuum reaching from the organic, tribal, or closed society, through the open society (marked by a critical attitude to tradition) to the abstract or depersonalized society lacking all face-to-face interaction transactions.

Open outcry is a method of communication between professionals on a stock exchange or futures exchange, typically on a trading floor. It involves shouting and the use of hand signals to transfer information primarily about buy and sell orders. The part of the trading floor where this takes place is called a pit.

In an open outcry auction, bids and offers must be made out in the open market, giving all participants a chance to compete for the order with the best price. New bids or offers would be made if better than previous pricing for efficient price discovery. Exchanges also value positions marked to these public market prices on a daily basis. In contrast, over-the-counter markets are where bids and offers are negotiated privately between principals.

A liaison officer is a person who liaises between two or more organizations to communicate and coordinate their activities on a matter of mutual concern. Generally, liaison officers are used for achieving the best utilization of resources, or employment of services of one organization by another. Liaison officers often provide technical or subject matter expertise of their parent organization. Usually, an organization embeds or attaches a liaison officer into another organization to provide face-to-face coordination.
