Results for Twitter

Description

Twitter is an online application that is part blog, part social networking site, and part mobile phone/instant messaging tool. It is designed to let users describe what they are doing or thinking at any given moment in 140 characters or less. As a tool for students and faculty, Twitter could be used academically to foster interaction and support metacognition. Sadly however, there are a few access problems although the RNIB have joined the Twitter scene but the good news is that you can now use a different version called Accessible Twitter or try Jawter: Twitter from Jaws with no software in the middle.

Accessibility Testing Results

The registration is through the Re-Captcha system - not ideal for everyone and not labelled so although it can be tracked in WebbIE some screen readers may miss the audio version. The forms in Twitter are not labelled although they are keyboard accessible. Otherwise it is a very simple concept that is provided with good contrast and text sizes and zooms well.

#	Test	Score	Summary
1	Login, Signup and Other Forms Accessible		Signup form uses ReCaptcha which is meant to be accessible to screenreader users by offering an audio version but may cause comprehension difficulties due to lack of clear audio output. The visual form can also be difficult to interpret.
2	Image ALT Attributes		Very few images. Image links to other user pages are tagged. Some icons and smaller images lack alts.
3	Link Target Definitions		Most links, including images which would otherwise be ambiguous, have titles to uniquely identify them, but there are some "click here" links.
4	Frame Titles and Layout		No frames or iframes, which can be disorientating for screen-readers, are used in the design.
5	Removal of Stylesheet		The page is still understandable and functional when it is viewed as a linear document, with no styles.
6	Audio/Video Features		The site only allows for 140 characters of text and no images or audio.
7	Video/animations - audio descriptions		The site only allows for 140 characters of text and no images or audio.
8	Appropriate use of Tables		Tables are not used for the design of this website.
9	Tab Orderings Correct and Logical		Tab order is in a logical and consistent top-to-bottom or left-to-right format. The order also holds within tables and forms.
10	Page Functionality with Keyboard		The website is fully accessible without the use of a mouse.
11	Accessibility of Text Editors		This site has no rich text editor. It is possible to tab directly into the message form.
12	Appropriate Feedback with Forms		The product provides suitable feedback when the user performs an action, with no time restriction.
13	Contrast and Colour Check		Generally adequate contrast between text and background, although some non-critical text has a poorer luminosity ratio.
14	Page Integrity when Zooming		The website maintains the layout and usability of all critical areas perfectly when zoomed.
15	Text size, style, blinking elements and Readability		The majority of text on the site is size 12 and sans-serif. There is no flashing or blinking content.
