Epistemology Research Of Human Computer Interface

The aim of this thesis is to give a new depictive perspective of HCI research by epistemology, so at the beginning of this thesis, an epistemological meaning of HCI is described, which is presented on the coordinate axis of nature world and life world. The HCI is regarded as an interactive medium between subject and object. And furthermore, we can consider it a medium of language symbol or a medium of special information. On one side, it is the display and the peripheral equipment of computer, on the other side, it is human action which is coterminous with the screen and the data. Thus something like word processing, Boolean query, and hypertext are not the complementarities but the components of HCI. It is the proper and the pivotal meaning of the epistemological meaning of HCI that surpass the meaning of the common medium.It has three characteristics : the opening of understanding, the fusion of public scene, and intelligence.The second part expounds the subject and object of HCI. The subject with traditional meaning has changed. HCI builds a new subject, which is further to be virtualized. To understand the process of virtualization, we must emphasizethe meaning of information management. The object of HCI is regarded as the environment of subject from ecological perspective. We call the environment "NOT CGT ENVIRIONMENT", which surpasses the "WORLD III" of Popper because of its intelligence and independence.The third part discusses the nature of HCI respectively from three perspectives: the idea of phenomenology, the question concerning technology, and the fusion of horizons.Phenomenology defines phenomenon as "something which gives us knowledge". It is HCI that can give us such kind of knowledge, so if we depict HCI as "something which gives us knowledge", HCI is thus given a meaning of phenomenology, then the nature of HCI is regarded as an object which makes the object of transcendental intuition present.Heidegger emancipates phenomenology from the ideology. He thinks that nature is not an object of transcendental intuition which is similar to the perceptible object, but regional horizons. As to Heidegger's view, when we study the nature of HCI, we should study not only a presented object of transcendental intuition but also the experience structure when HCI is presented as phenomenon. How to understand the experience structure? Heidegger puts forward a good perspective by "the question concerning technology". From this perspective, HCI presents a new pattern of being for human, and mean-while constructs the way in which we understand the world. So HCI is a method of aletheia, which is regarded as a kind of destiny Gestell by Heidegger.In the Being and Time, although the nature structure actually resorts to presence, the common fact is not the analysed object. However, if we regard the nature of HCI as regional horizons, it should include the phenomenon relations of the realistic and the historic. In Gadamer's view, the history stands the past horizons, which enter into the contemporary era by our understanding and fuse with our horizons. And thereby the history is given a new meaning of the contemporary era to us, and we are improved by the history.In a word, no matter what HCI is considered, "phenomenon", or "Gestell", or "horizons", we should understand them by the means of fusion and permeation between subject and object.Lastly, the effects of HCI on human cognition is discussed. The thesis points out that the basis of effect are not only that HCI is a kind of language symbol medium system, but also that it provides a cognitive model which combines simultaneousness of time and integrality of action. This model imitates the God's omniscient intuition, which is not limited by the extension in time and the straight step in action.
