Prats, Miquel; Garner, Steve; Jowers, Iestyn; McKay, Alison and Pedreira, Nieves (2010). Interpretation of geometric shapes – an eye movement study. In: Proceedings of the 2010 Symposium on Eye-Tracking Research & Applications, ACM, pp. 243–250.



This paper describes the first in a series of studies which seek to explore the correlation of eye movements with interpretation of geometric shapes. These studies are intended to inform the development of an eye tracking interface for computational tools to support and enhance the fluid interaction required in creative design. A common criticism of computational design tools is that they do not enable manipulation of designed shapes according to all perceived features. Instead the manipulations afforded are limited by formal structures of shapes. This research examines the potential for eye movement data to be used to recognise and make available for manipulation the perceived features in shapes. The objective of this first study is to analyse eye movement data with the intention of recognising moments in which an interpretation of shape is made. Results suggest that duration of fixation and distance between successive fixations prove to be consistent indicators of shape interpretation.
