Abstract

This paper describes an empirical study in which children aged 7 and 8 used handwriting recognition software and hardware to input their own unconstrained text into the computer. The children were observed using the software, and the behaviour of both the children and the system is described.Handwriting recognition is a 'disobedient' technology; that is, it behaves erroneously, sometimes failing to generate correct representations of the child's intentions. This presents problems for the child, and these problems, and the strategies which the children adopted, are considered. Previous work on error correction with disobedient interfaces is used to provide grounding for the discussion.Two models are proposed, one describing user-states, the second introducing the notion of 'tidal' error repair. These models are then used to suggest some strategies for the design of more usable handwriting recognition interfaces for children.
