Blurred lines: Accessibility, disability and definitional limitations.
This paper explores the history and utility of the concept of “accessibility” in relation to the iPhone and similar devices, and the difficulties of differentiating between accessibility for people with disability and usability concerns for the general public. Elizabeth Ellcessor is assistant professor of cinema and media studies, and has an engaging way of writing. She says the case of iOS7 indicates the difficulties of defining both accessibility and disability in the contemporary moment. Increasingly, the lines between accessibility and usability, disability and difference, accommodation and preference are blurring.
The author uses disability theory to argue that access is a complicated phenomenon, and that even given the difficulties in establishing definitions of “accessibility,” the concept is worthwhile because it carries with it reminders of the politics of difference, the difficulties of access, the history of disability rights, and the relationship of media to civil rights and public participation.

Rather than using a PowerPoint presentation, an actor with a script written by the researcher, Steve Daunt, communicates the results of his study. The script compares the difficulties older people face with everyday technology such as a mobile phone with the alarm pendant. It highlights how these pendants may not be as effective as the designers might think.
The study uncovered many device design issues that the users struggled with – such as buttons being the same colour as the device casing. Contextual use of the device was found to be an issue for the older users; for example, where reduced mobility and dexterity made it difficult to reach down to and operate a DVD player placed at a low level relative to the ground.
One major finding from the pendant alarm technology was that the older people assessed were mostly unsure or unaware of what steps would occur after they had pressed the alarm button.
Many of the designs that older users struggled with in their “difficult technology” made no allowance for users lack of technical knowledge or exposure. Some of the designs were found to be extremely poor and it is likely that other user groups would also have had difficulty with the technology. For example, some devices lacked labelling or feedback which are violations to basic usability principles.
Initial findings from the study were presented as a “dramatic reading”at the ActivAge 2012 conference. You can access the 15 minute video at the bottom of the webpage.
The title of this research paper is “DREAM work package: Monitoring the Implementation & Enforcement of eAccessibility law and policy at the Member State level”
E-accessibility refers to the design of information and communication technologies that are usable by persons with disabilities. The principle aim of this study was to identify how different intermediaries (e.g., policy approaches, participatory processes and commercial incentives) impact the monitoring, implementation and enforcement of e-accessibility policies. DREAM is the acronym for a group of member states interested in this endeavour. The findings revealed:
- The need to develop an international procedural standard
- The need for a web accessibility professional association
- The need for a procedural accreditation

Abstract: This paper concerns an investigation by the authors into the efficiency and user opinions of menu positioning in web pages. While the idea and use of menus on web pages are not new, the authors feel there is not enough empirical evidence to help designers choose an appropriate menu position. We therefore present the design and results of an empirical experiment, investigating the usability of menu positioning on web pages. A four condition experiment was conducted by the authors. Each condition tested a different menu position. The menu positions tested were left vertical, right vertical, top horizontal and bottom horizontal. The context was a fictitious online store. The results, based on statistical analysis and statistically significant findings, suggest that the top horizontal and left vertical positioned menus incurred fewer errors and fewer mouse clicks. Furthermore, the user satisfaction ratings were in line with the efficiency aspects observed. Download the article here PDF
