Usability Spotter #5: HP Laptop Touch Pads with Scroll Zones- Absence of Tactile Cue

Summary The issue with HP laptops that have a touch pad with a scroll zone contained it (as shown in image A) is that they do not provide a tactile cue for the user to help interpret what section of the touch pad the finger is positioned at. In the absence of a tactile cue, it is difficult for the user to determine whether the finger is on touch pad or the scroll zone without looking at it, resulting in the accidental scrolling on the screen when actually the user simply wants to move the cursor. The issue and multiple solutions are discussed ahead.

Designing for Screen Reader Compatibility

Techniques that work for one screen reader almost always work in other screen readers. In some cases, one of the screen readers has capabilities that the others do not have, or handles some types of content better than the other screen readers. Still, developers are almost always better off when they focus on accessibility standards and generally-accepted accessibility techniques than when they focus on screen reader differences.

Adopting WCAG 2

It is six months since the release of WCAG 2.0 and I thought it might be interesting to see how extensively it has been adopted as a bench mark for determining web content accessibility. Over this time, I have felt that the rate of adoption has been relatively slow and the number of countries and other regulatory authorities now using WCAG 2 is lower than I expected.

Web Design For Dyslexia

People with dyslexia frequently experience discomfort when reading because they find it more difficult to ‘decode’ the words on the page, and can also find it difficult to remain focussed on a particular piece of text. Some people may also have to concentrate more to remember what they have already read, which means they will tire more easily.

From Web Accessibility to Web Adaptability  

This article asserts that current approaches to enhance the accessibility of Web resources fail to provide a solid foundation for the development of a robust and future-proofed framework. In particular, they fail to take advantage of new technologies and technological practices. The article introduces a framework for Web adaptability, which encourages the development of Web-based services that can be resilient to the diversity of uses of such services, the target audience, available resources, technical innovations, organisational policies and relevant definitions of 'accessibility'. Method The article refers to a series of author-focussed approaches to accessibility through which the authors and others have struggled to find ways to promote accessibility for people with disabilities. These approaches depend upon the resource author's determination of the anticipated users' needs and their provision.

Designing for "Mature" Users

According to a study by the Annenberg School at USC, American Internet users include: 75% of adults aged 56-65 and 41% of adults over 66. If we want to design for the bulk of our users, we had best consider the more mature user groups.

HTML 5 and Accessibility

Probably the most worrying thing about the HTML Working Group is the lack of respect for differing opinions that some working group members have. The apparent disinterest in accessibility is another troublesome factor.

HTML 5, Microformats and Testing Accessibility

Testing is vital, particularly at the border of accessibility theory and practice. I wonder, for example, if tabindex and accesskey would have made it to the HTML4 spec if there had been full testing with assistive technology users? What I really want to know from the HTML5 people is who they think is going to do this research that will provide the evidence that their gang requires before useful attributes are restored to the specification.

HTML 5 and the Summary Attribute

As I wrote in Help screen reader users by giving data tables a summary, the summary attribute on the table element can be used to provide information that helps non-sighted users understand data tables. The current draft of HTML 5 requires that validators display a warning if they encounter a summary attribute, since it is now an 'obsolete but conforming feature.'

Be Kind to the Color Blind 

Using color and color alone as a visual cue is appealing because it’s usually an aesthetically pleasing and a minimalist design technique. Calls to action and visual cues are critical to interface designers because users, especially on the web, have limited patience and are looking to process information and make decisions quickly. Since the brain recognizes and forms an emotional bond with colors almost immediately, colors are a natural choice for visual cues. Unfortunately, it’s easy to alienate or confuse some of your users when some of those aesthetically pleasing colors look very similar. To point out a few interfaces that use hard to differentiate colors as visual cues, here are a few examples that have given me some trouble.
