Day 6# Learn about assistive technologies and share one you loved (hardware) • Assistive technology is any device, software, or equipment that helps people work around their challenges. • Some examples of assistive technology are text-to-speech and word prediction. • Assistive technology includes low-tech tools, too, like pencil grips. Sip-and-Puff Systems Sip-and-puff systems are used by students who have mobility challenges, such as paralysis and fine motor skill disabilities. These systems allow for control of a computer, mobile device, or some other technological application by the child moving the device with his or her mouth. Similar to a joystick, the child can move the controller in any direction and click on various navigational tools using either a sip or a puff. An on-screen keyboard allows the child to type using the same movements. Sip-and-puff systems are a type of switch device, which refers to the technology used to replace...

Day 28 # T esting a word document issues for accessibility I have downloaded a word document from online and used an inbuilt accessibility checker to check the issues. There I observed some missing alternative texts, images, or objects not inline, check the reading order, hard-to-read text contrast. I tried to change the contrast and solved the issues by changing font and color contrast. What the Checker Won’t Do If your headings are text made big and bold, not real headings, the accessibility checker won’t see a problem. So you will also have to check headings yourself. The checker will tell you if an image has no alternative text. But it can’t tell if an image has an inaccurate or badly-written alternative text. So you must check all images, even if the checker says they are OK. You’ll also have to check whether your page is using tabs where it should use a table, fonts, like Wingdings, where it should use images, or images where it should use text....
