Application of dynamic graphics techniques to the appraisal of domestic activity spaces.

Hammond, Brian G.

Abstract

The work contained in this thesis can be conveniently considered as falling into three distinct sections. The first section investigates existing methods for man/machine communication in terms of geometry input. Utilising the results of this investigation the key possibilities for improved user interfacing using dynamic graphics were identified as 1.Dynamic numerical feedback for improved locational accuracy. 2.Line rubber banding for location of edges and/or vertices during primative object creation and manipulation. 3.Object translation in the x,y plane. 4.Increased use of alphanumeric feedback as a prompt and confirmation mechanism. The second section investigates existing domestic activity space models and determines ergonomic data for a particular space activity instance(the domestic kitchen). A novel domestic activity space model is then presented based on four penalty factors: 1.A penalty factor based on the economy of the bounding area of the activity space. 2.A penalty factor based on the economy of the enclosed volume of the activity space. 3.A weighted penalty factor based on the assessment of three dimensional overlapping of space categories (furniture and associated user areas). 4.A weighted penalty factor based on the assessment of the association distance between pairs of space category elements. The third section represents an integration of the two sections above. A computer based implementation of the activity space model, using dynamic graphics, is presented. On the basis of comparison between subjective evaluations of a real activity space situation and a computer appraisal, the model is validated. The system provides the architect/designer with a novel and flexible design and appraisal technique, which increases the speed and more importantly the quality of his work in designing adaptable, marginal layouts. Furthermore the system lends itself to a number of other space utilisation applications as well as forming an excellent basis for design participation.
