A Microtheory of Visually-Derived Information
نویسنده
چکیده
In human-computer interaction, information is most commonly conveyed from computer to user by being shown on a VDU or other kind of visual display. By seeing and interpreting what is shown on the display, users come to know things both about the objects on the display and about other entities those objects depict. From a formal point of view, how does this process “work”? This paper presents a simple microtheory of how users acquire information from visual displays. The intention is for the microtheory to serve as a standard analysis of visually-derived information, to be included as part of more complete formal descriptions of devices and users.
