Dr Christopher R Roast PhD

Reader


Summary

Chris has worked in a variety of areas oriented to practical and applied research within computing and interaction design. He enjoys in the inherently cross-disciplinary nature of digital device and service design, and how digital technology can mediate the transition from users who are unfamiliar with a technology to users who effectively benefit from it. He has worked with a variety of other disciplines including: Product Design, English Literature, Cultural Studies, Robotics, Nursing, Education, etc..  His applied research focuses upon the usability of notations and tools for defining and controlling information artefacts; and the principles by which information artefact design can be characterised; and the design and development of visualisations;

He has an active interest in a number of areas including: VR and AR; Design for others; Sentiment Analysis; Non-trivial online form design, knowledge transfer and innovation.

About

Chris has worked in a variety of areas oriented to practical issues within interaction design. He is interested in the inherently cross-disciplinary nature of digital service and product design, and how digital technology mediates its effective use. Having completed a Masters in Design Research at the RCA, he went to work on an early interactive video training project at Imperial College of Science and Technology. This experience demonstrated a 'intelligent tutoring system' failing to co-ordinate user interaction with educational video content. This led to Chris's interest in HCI. He completed a PhD and The University of York attempting to capture concepts about good interaction design that could be applied generally and reasoned about formally. During that time he encountered the idea of Cognitive Dimensions of Notations, as a similar research thread motivated by psychology.

Chris started teaching towards the end of his PhD and has continued to teach undergraduates and post-graduates since.

While remaining research active, he has became more interested in applying his expertise and experience. Over the last ten years has been more involved in applied inter-disciplinary research. This has involved numerous collaborations and has resulted in an interest in knowledge transfer and innovation. He has worked on industry based projects of various sorts for the last six years. Chris has also been a knowledge transfer lead, encouraging and facilitating others in engaging in collaborative practiced based work.

Chris is interested how our interaction with technology offers great opportunities and how they are often thwarted by misconceptions and complexities. Good design can make technology more accessible but often the actual complexity is badly hidden!

Chris has worked extensively with industry linking research activity with industry needs and innovation.
