A pilot study exploring electronic mail in users with acquired cognitive-linguistic impairments ; Brain Injury, 17(7), 609-629.

ABSTRACT

This paper reports the results of an exploratory study into the usability of a simplified e-mail interface for eight individuals with acquired cognitive-linguistic impairments. Participatory Action Research, a qualitative research method, was used to capture the range of performance variables and to emphasize a 'user-centred' approach to the research process. The participants were asked to read and reply to e-mails across four writing prompt conditions. An analysis of errors and participant preferences for the prototype e-mail system was conducted. Errors fell into two general categories: (1) computer usability (e.g. conceptual understanding of mouse/cursor operation) and (2) message composition (e.g. generating ideas for a message). Participant preferences for the writing prompt conditions varied considerably. All participants endorsed the use of customized e-mail interfaces as a means of connecting with friends and family, thereby reducing social isolation. Implications for interface design, rehabilitation and future research into assistive technology are discussed.
