Computer dodgings - Essay workoutBut due to the fact that interface of most computer systems has limited range of expressions, users has no opportunities to act with them as with real people.Current tools, such as email, mailing lists, chat rooms, discussion phorums have unattackable shortcomings. Their interface is designed except for delivery of simple ideas, without emotions, gestures or face expressions. Of course people give the axe use so-called smiles (primitive pictures with emotions, such as smile or sadness), but every system has its protest predefined set of smiles and does not allow user to insert custom image instantly.At the same sequence in a physical world people can easily express emotions in a discussion over a meal or a drink, meeting up at a conference or having a special offer pointed out to you by behaviour of a stranger. societal discipline in a physical world is transmitted on many levels.

Work here ranges from attempts to i mplement a virtual physics to the good looser representations of social information found in the 2-D and three-D avatars found in various graphical MUDs and 3-D VRML worlds. While the use of mimetic representations decreases some of the bandwidth requirements of such systems, in this sort of system social signals must be consciously produced via users manipulating their avatars.The abstract approach involves portraying social information in ways that ar not closely tied to their physical analogs. Exemplars of the abstract approach include AROMA, the Out to Lunch system (which uses abstract sonic cues to indicate socially salient activity), and Chat Circles (which uses abstract visual representations). This approach withal includes the use of text to portray social information.
