![]() Use the Associative Property of Addition. ![]() Use the Commutative Property of Addition. In these cases we use a table to lay out the equation and associate the notes with each row as follows. In some cases each row of an equation will have notes that relate to the row. For the case where equations are involved it is suggested to not use the structured navigation mode provided by ChromeVox and simply read the linearized table. Some times these will be data tables and sometimes they will be used to associate work notes with lines of an equation. In contrast to the MathML tables mentioned before there will also be times that HTML tables will be encountered. The following are examples of common layouts that students will encounter when using the Hawkes math material: A very simple math equation appears below.ġ + 1 = 2 JAWS Simple Math NVDA Simple Math ChromeVox Simple Math The style in which mathematics is announced is dependent on the screen reader and can vary. ![]() There are several different screen reader applications that can interpret MathML, including The use of MathML provides a structure that allows screen readers to navigate an equation and provide context necessary for correct announcement. The mathematics in Hawkes material is encoded in the MathML language. Toggle structure and semantics mode for math JAWS Keyboard Shortcuts NVDA Keyboard Shortcuts ChromeVox Keyboard ShortcutsĬhromeVox Keyboard Shortcuts Key CombinationĮnter structured content, such as tables or mathĮxit structured content, such as tables or math Use of greater than indicates that a key press should follow the keystrokes prior to the greater than sign. The use of the plus sign indicates that keys should be pressed together. Keyboard Shortcuts by Screen Readerīelow are useful keyboard shortcuts for specific screen readers to aid users in navigating Hawkes material. NVDA or JAWS by our Accessibility Team, seems promising, especially in regards to customer feedback and is recommended for MacOS users. ChromeVox, although not as heavily tested as Additionally, we concluded that JAWS implementation of equation navigation was unintuitive (see SR specific section for JAWS), validated as well by user testing. However, during testing, the Accessibility Team felt that the interpretation of mathematics and information provided for interactive portions of our material by NVDA, to test our material while determining best practices and updates to the interactive portions of questions. We used several different screen reader applications, primarily Jaws and MathPlayer 4 can be obtained for free from Design Science. ChromeVox is recommended for MacOS users. NVDA screen reader in the Firefox browser for Windows users. The Hawkes Accessibility Team recommends using the Overall, this means that screen readers rely on well-structured web pages for easy navigation. Screen readers with advanced functionality can generate lists of hyperlinks or headings and “jump” to them. In terms of web content, this means allowing the user to navigate through a web page by announcing when a user has reached a button, link, heading, or other element of interest. ![]() Additionally, screen readers provide navigational aids to the user. In many instances this simply means reading aloud the text that is on the screen to the user. Screen reader software receives information from other applications and transforms that information into speech. In actuality, a screen reader is a piece of software that exists on a user’s computer. Many people envision a screen reader as a device that is external to the computer. Here you'll find our recommendations for screen reader programs that work best with Hawkes on the web! What is a Screen Reader? Through the course of the accessibility initiative at Hawkes, we have tested with a variety of different screen reader programs based on availability and popularity.
