Current Funded Research Projects

Co-motion

I am co-investigator on this project, led by the Centre for Housing Policy (CHP). It has received £1.2m funding from the EPSRC, ESRC and AHRC for a three-year 'Design for Wellbeing' project investigating the links between mobility and wellbeing amongst older people. Over three years, the work will include a longitudinal study of older people in York, Hexham and Leeds who have experienced transitions affecting mobility and wellbeing such as losing their driving license, losing sight, becoming a carer, or starting to use a mobility scooter. This will lead into intensive co-design workshops with older people, covering experimental crowd sourcing and participatory GIS on mobility barriers, deliberative approaches to conflicts between diverse needs, mobility apps for iPhones, mobility scooter design adaptations, and a typology of neighbourhoods according to mobility characteristics and suitability for interventions. There will also be work with national and local stakeholders.

Research Interests

Person using a conventional computer interface

The human-computer interface is almost synonymous with a screen, a keyboard and a mouse, but this form of interface is unnecessarily restrictive. It does not make the most of the abilities of the user and it also disadvantages users who for whom those devices are inaccessible.  I am interested in 'novel' forms of human-computer interaction beyond this paradigm. Much of this work has been prompted by the needs of people who would be identified as having disabilities, but it soon broadens out beyond them.

Specific topics I am interested in include:

Research opportunities

Note

From October 2015 I will be working part-time. Part of the consequent reduction in my commitments is that I will not be supervising Research Students. There will thus be no point in applying to undertake a research degree with me. I leave the following in, nevertheless, for completeness.

I am interested in hearing from potential research students interested in researching a range of topics related to those described in these pages. I am interested in people who might like to pursue any of the following topics - but I will be even more interested in related topics that I have not even thought of. A PhD is the student's own work, their original contribution to knowledge, and the best place to start is with your ideas. A vital part of the application for a research studentship is thus the Research Proposal, and I have produced some notes to help you in writing one.

Applicants may find the following blog useful, How not to suck at grad school from McGill University, Canada.

Please contact me if you are interested in any of these topics - or similar areas of research.

Non-speech sounds

Humans experience the phenomenon of visual dominance - in a number of forms, but equally apparent in human-computer interactions, where screens are often crowded with information. Cause and effect may be hard to separate, in that screens can be very efficient because of the power of vision. Nevertheless, there are many instances in which information can or should be presented in an auditory form. An obvious example is where the visual channel simply is not available, due to blindness.

Speech is one use of the auditory channel, but there is vast scope for the use of non-speech sounds, a potential which is very much under-used by the simple 'beeps' of contemporary computer interfaces. There is scope for a great deal of work to find out how better to use this channel.

Interaction for visually disabled users

This is where my own research started, and I maintain an enthusiasm. I would be interested in any ideas to be developed in this area, particularly anything novel and radical. Some specific ideas and areas are outlined below.

A natural language interface to drawing for blind people

Graphics present a difficult challenge for blind people. David Bennett completed a PhD on transforming diagrams into a non-visual form for blind people to read, but another problem is that of creating diagrams. Student projects by Wilson and Reid investigated the possibility of creating diagrams through a natural language interface. For instance, one might issue the commands, 'Draw a circle. Draw a square next to the circle' and so on. Results were encouraging, so that there is scope to take this work further, to investigate a theoretical basis and to implement a usable package.

Internal representations of mathematics

Publications from the Maths Project frequently asserted that mathematics is a cognitive activity, something that is done 'in the head' - and therefore something that should be equally feasible for a blind person as a sighted one. Yet I am afraid that we never explored the real implications of that assertion. Some mathematical manipulation is indeed done in the head, but if that is the case, then there has to be some internal representation that the 'thinker' is accessing. To build tools like the Maths Workstation - it would be most valuable to have a better understanding of what sorts of internal representations of mathematics people use - and particularly those that might be used by blind people. It seems that the Interacting Cognitive Subsystems (ICS) model would be a good place to start.

A related interest is in the cognitive modelling of the reading of contracted braille. I had an undergraduate tackle this in his final-year project (Clapham, 2006), but it was quite an ambitious problem for an undergraduate, and there is a lot more to be looked at which would make a good PhD topic.

Haptic and tactile interaction

We hope to investigate this both as an alternative form of interaction for blind people and as a more fundamental research/development question. This would link well to the work of the former University of York Centre for Tactile Images.

Possible topics for research include:

Ambient sounds and mode awareness

Ambient sounds are the kind that sink into the background of your consciousness most of the time, but which you are aware of if you listen for them or if they change (perhaps subtly). We are interested in the possibility of using these properties for communication, and in particular whether they can be used to make the user aware of being in a particular mode.

Record

In these days of performance indicators, it seems appropriate that I should be open about completion rates (as of 28/8/2012):

18 people have commenced PhD research under my supervision.
10 successfully graduated.
1 was awarded an MPhil.
1 completed an MSc by research after 2 years. 1 returned to her home country, with the intention of completing her PhD there. 1 is currently still working on her research and on-course for completion shortly.
3 dropped out. Of them, 1 was offered the opportunity to write up for an MPhil, but declined and withdrew.
1 did not complete writing up of the thesis.

In addition 1 student undertook an MSc by research, full-time and successfully graduated

I count that as 10/18 (55%) positive results.

15 were full-time, 2 part-time.
