Using personal computers to create sounds and graphics for a large scale installation

Thesis (M.S.V.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1985.MICROFICHE COPY AVAILABLE IN ARCHIVES AND ROTCH.Includes bibliographical references (leaves 90-93).Personal computers are easy to program, inexpensive and portable. With two Commodore 64 computers, I created an artistic installation entitled "Songs in the Language of Information". It was composed of elements reflecting time, space, light, action and predictability. The two computers controlled projected light patterns, complementary synthesized sound and interactive relays triggered by viewers crossing light beams. The following thesis documents "Songs in the Language of Information". The "Introduction" presents background development leading up to this work. All components of the installation are discussed in "Physical Description" and "Analysis of the Work". A survey of selected recent and past work that has been influential to me is outlined in "Historical Precedents". "The Program" illustrates graphic elements, presents flow charts and lists programs of all subroutines used in the installation. The "Conclusion" offers what for me is the next step in my artistic work with computers.by Sarah Geitz.M.S.V.S

External Variables, Beliefs, Attitudes and Information Technology Usage Behavior

The Technology Acceptance Model (TAM) predicts the user acceptance of end-user applications by specifying causal relationships among belief and attitudinal constructs that subsequently influence usage behavior. Although the perceived usefulness and perceived ease of use constructs have received a great deal of attention in MIS literature, very few follow-up studies have used the original TAM constructs. Moreover, the various studies investigating TAM use different measurement items, or factors, to assess the belief constructs. In this TAM study, the impact of external variables affecting usage behavior is examined. The results suggest that the impact of the external variables on usage behavior is not fully mediated by the belief constructs.
