Understanding the semantics of web interface signs: A set of ontological principals

Abstract

Interface signs are the communication artifacts of web interfaces, with which users interact. Examples of interface signs are small images, navigational links, buttons and thumbnails. Although, intuitive interface signs are crucial elements of a good user interface (UI), prior research ignored these in UI design and usability evaluation process. This paper argues that ontology (the set of concepts and skills for understanding the referential meaning of an interface sign) mapping is critical for intuitive sign design. A light weighted experiment with six participants and twelve signs has been carried out in order to demonstrate the importance of ontology mapping in understanding the semantics of interface signs. The paper concludes with some practical implications and suggestions for future research.
