  • Performance Ritual and the Design of Mobile Devices
    Performance ritual and the design of mobile devices Submitted by Kym R. Campbell th 30 May 2016 Thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at the University of Canberra, Australian Capital Territory, Australia Abstract This thesis argues that concepts of secular ritual, drawn from the work of Erving Goffman and James Carey, can provide a useful way of understanding the relationship between the production and design of mobile devices and their use, and hence provides further insights into the broader relationship between mobile technologies and society. This argument is developed by reviewing scholarship on the relationship between technologies and society, before engaging with ritual as a secular concept and a way of understanding human relations with technology. James Carey's work on ritual and communication is key to linking technology with ritual, while Erving Goffman's work on ritual and performance provides a way to develop a framework for further analysis. The ritual performance-oriented framework is described here as the theatre of design, and acts as a metaphor for describing the dynamic between society and the mobile device. In essence, this approach argues that we can understand our relationship with mobile devices as a performance in which the device can be a prop, users can be thought of as actors, and designers take on the role of director. To develop this framework further, the device is examined through a sociocultural lens. Du Gay et al’s circuit of culture is utilised to illustrate how meaning comes to associate with the technology.

Ultimate goal was to have a machine do the calculations. 2 advantages: • Speed • Accuracy Analytical Engine In 1832, Charles Babbage designed the Analytical Engine • a mechanical general purpose programmable computer • Programs and data on punch cards. • A store (i.e. memory) for holding 1000 numbers of 40 decimal digits • The arithmetical unit called the “mill” would be able to perform all four arithmetic operations, comparisons and square roots Cost, construction challenges and the Engine’s size meant it was never built The first computers It took clerks 8 years to manually
