As a concept of Social Interface Theory: Long (1989, 2001) definition was:
‘.. a social interface is a critical point of intersection between different lifeworlds, social fields or levels of social organization, where social discontinuities based upon discrepancies in values, interests, knowledges and power, are most likely to be located.’
The basic thesis of Social Interface Design is how a computer interface can be more akin to human gestures and facilitate correct responses from users during human-to-computer interaction. Software that can provide such humanizing cues often does it by creating interface with human-like quality; such as giving recognizable gender to a software.
An example of this has been conceived by designer John Villarreal, the “e-mote” is a remote electronic user interface to control any number of electronics with minimum fuss. The e-mote connects to your mobile phone using Bluetooth, while internal bio-sensor displays lighting to physical state such as heartbeat, blood pressure and body temperature. The lighting on the device indicates high stress level, and this e-motion level can be posted to your social network.
