Affordance and Symmetry

چکیده
Whilst it is generally accepted as a positive criterion, affordance only gives the weakest of hints for interactive systems designers. This paper shows how useful it is to consider affordance as generated by a correspondence between program symmetries and user interface symmetries. Symmetries in state spaces (for instance, as might be visualised in statecharts) can be carried through to user interfaces and into user manuals, with beneficial results. Exploiting affordances, understood in this way, in addition to their well known user interface benefits, makes programs simpler and more reliable, and makes user manuals shorter.

to have any psychological validity. Further work is called for, and we suspect a fertile area will be in defining homomorphisms between the groups of different system representations: for example, between the physical user interface and the structure of the transition system ‘underneath’ it. There is also a mischief element in human nature that our examples can highlight as another form of affo...
متن کاملThe Cognitive Symmetry Engine
We propose the use of symmetry theories as the basis for the interpretation of sensorimotor data and the creation of more abstract representations. Here we outline a cognitive architecture to implement such an approach and provide a set of specific mechanisms for 1-D, 2-D and 3-D sensorimotor processing. The overall goal is to integrate low-level sensorimotor data analysis and behavior with mor...
متن کاملBiofunctional Understanding and Judgment of Size
Research has shown that the meaningfulness of the material increases judged size, whereas symmetry decreases size judgments. These findings have been interpreted in terms of information processing, with a greater quantity of information leading to a judgment of larger size. An alternative view based on biofunctional understanding theory emphasizes the quality of affordance-triggered biological ...
