Involving People with Disabilities: Lessons from a Designer-Centred Inclusive Design Competition (2008)

Joy Goodman, Engineering Design Centre, Julia Cassim, Helen Hamlyn Centre, Patrick Langdon, ...

Involving end-users can make a real difference in producing products and designs that actually meet their needs and wants. This is particularly important when it comes to older and disabled users,...

Formats for User Data in Inclusive Design (2008)

Joy Goodman, Patrick Langdon, P John Clarkson

Abstract. Although information about users is vitally important in inclusive design, its use is often limited. The literature suggests that this is, at least in part, due to the ways in which the...

INDUSTRY RESPONSE TO INCLUSIVE DESIGN: A SURVEY (2008)

Joy Goodman, Patrick Langdon, P John Clarkson, Hua Dong

Inclusive design (ID), that is, design for a wide range of potential users, including those who are older or have disabilities, can have significant commercial benefits, tapping into a large and...

The Effect of Multiple Haptic Distractors on the Performance of Motion-impaired Users (2008)

Faustina Hwang, Patrick Langdon, Simeon Keates, P John Clarkson

Abstract. The effect of multiple haptic distractors on target selection performance was examined in terms of times to select the target and the associated cursor movement patterns. Two experiments...

Cognitive Scales and Mental Models for Inclusive Design (2008)

Umesh Persad, Patrick Langdon, P John Clarkson, David Brown

Abstract. In keeping with a user capability and product demand approach to product assessment, this paper examines the cognitive demands placed on users when interacting with consumer products. The...

6th ERCIM Workshop "User Interfaces for All " Short Paper Investigating the use of force feedback for motion-impaired users (2007)

Simeon Keates, Patrick Langdon, John Clarkson, Peter Robinson

Abstract: For users with motion impairments, the standard keyboard and mouse arrangement for computer access often presents problems. Other approaches have to be adopted to overcome this. There is...

Universal access to assistive technology through client-centred cognitive assessment. (2004)

Adams, Ray G., Clarkson, John, Langdon, Patrick

This paper provides a rigorous, innovative case study methodology that had not been used before in this way in this field. It captures the diversity of user requirements, by focussing systematically...

Multiple haptic targets for motion-impaired users (2003)

Faustina Hwang, Simeon Keates, Patrick Langdon, P John Clarkson

Although a number of studies have reported that force feedback gravity wells can improve performance in “pointand-click” tasks, there have been few studies addressing issues surrounding the use...

Investigating haptic assistive interfaces for motion-impaired users: Force-channels and competitive attractive-basins (2002)

Patrick Langdon, Faustina Hwang, Simeon Keates, P John Clarkson

Following a pilot study that suggested that force-feedback gravity wells could, under certain conditions, lead to 20-50 % improvements in time to target in a selection task, a series of experiments...

A systematic basis for developing cognitive assessment methods for assistive technology. (2002)

Adams, Ray G., Langdon, Patrick, Clarkson, P. John

Adams, R., Langdon, P. and Clarkson, P.J. (2002) A systematic basis for developing cognitive assessment methods for assistive technology. CWUAAT, Cambridge Workshop for Universal Access and Assistive...

Haptic Assistance to Improve Computer Access for Motion-impaired Users (2001)

Faustina Hwang, Patrick Langdon, Simeon Keates, John Clarkson

This paper describes a pilot experiment which examines the effectiveness of using force-feedback technology to assist motion-impaired computer users in target selection tasks. Two measures to...

Perception and haptics: towards more accessible computers for motion-impaired users (2001)

Faustina Hwang, Simeon Keates, Patrick Langdon, P John Clarkson

For people with motion impairments, access to and independent control of a computer can be essential. Symptoms such as tremor and spasm, however, can make the typical keyboard and mouse arrangement...
