Do (and say) as I say: Linguistic adaptation in human-computer dialogs
Get PDF© Theodora Koulouri, Stanislao Lauria, and Robert D. Macredie. This article has been made available through the Brunel Open Access Publishing Fund.There is strong research evidence showing that people naturally align to each other’s vocabulary, sentence structure, and acoustic features in dialog, yet little is known about how the alignment mechanism operates in the interaction between users and computer systems let alone how it may be exploited to improve the efficiency of the interaction. This article provides an account of lexical alignment in human–computer dialogs, based on empirical data collected in a simulated human–computer interaction scenario. The results indicate that alignment is present, resulting in the gradual reduction and stabilization of the vocabulary-in-use, and that it is also reciprocal. Further, the results suggest that when system and user errors occur, the development of alignment is temporarily disrupted and users tend to introduce novel words to the dialog. The results also indicate that alignment in human–computer interaction may have a strong strategic component and is used as a resource to compensate for less optimal (visually impoverished) interaction conditions. Moreover, lower alignment is associated with less successful interaction, as measured by user perceptions. The article distills the results of the study into design recommendations for human–computer dialog systems and uses them to outline a model of dialog management that supports and exploits alignment through mechanisms for in-use adaptation of the system’s grammar and lexicon
Swimming the channels: An analysis of online archival reference enquiries
No full textArchives of historical and cultural data, such as the UK’s National Archives, receive huge volumes of enquiries from users. These have been seldom systematically studied, despite the obvious benefits to the organisations concerned and interaction designers. The literature looking at the spectrum of remote communications carried out by a modern archive is sparse. Similarly, there is a lack of information about the problems users are having with archival information systems, and no information on the distribution of problems or where in users’ information seeking journeys they occur. This paper reports on a mixed-method study using content analysis and grounded theory to address these gaps in the literature. The results of the study indicate that users primarily are encountering problems knowing where to start looking or where to look next in their information seeking journeys. Further, these problems seem to create a deep anxiety or uncertainty in archive users which drives them to seek reassurance and guidance from human archivists, who will provide the type of disambiguation and support that current information systems do not. The paper closes with implications of this work on the future prioritisation of design practice and research in online archives
Handbook of human-computer interaction
No full textThis completely revised edition, of the Handbook of Human-Computer Interaction, of which 80% of the content is new, reflects the developments in the field since the publication of the first edition in 1988. The handbook is concerned with principles for design of the Human-Computer Interface, and has both academic and practical purposes. It is intended to summarize the research and provide recommendations for how the information can be used by designers of computer systems. The volume may also be used as a reference for teaching and research. Professionals who are involved in design of HCI will find this volume indispensable, including: computer scientists, cognitive scientists, experimental psychologists, human factors professionals, interface designers, systems engineers, managers and executives working with systems development. Much of the information in the handbook may also be generalized to apply to areas outside the traditional field of HCI.This completely revised edition, of the Handbook of Human-Computer Interaction, of which 80% of the content is new, reflects the developments in the field since the publication of the first edition in 1988.

Mapping virtual reality controls to inform design of accessible user experiences.
No full textA lack of accessible controls remains a barrier to disabled users engaging in virtual reality experiences. This paper presents a modified cognitive walkthrough of 120 virtual reality applications to identify 2,284 pairs of operant and resultant actions and creates an inventory of domain objects and their operant and resultant actions in the virtual space. This inventory captures both the form and prevalence of interactions that are expected of users in current virtual reality design. An analysis of this inventory reveals that while many barriers could be addressed by existing solutions, those options currently are not often present in current designs. Further, there are a set of barriers related to embodied controls that represent opportunities and challenges for new and innovative designs in virtual reality
