The visual aids available when taking a test in TAO are a set of tools which serves to help you to focus visually on a particular part of the test question in various different ways.
The Visual Aids which have been activated for a Test are displayed on the blue bar along the bottom of the screen. There, you will find both the name of the tool and a corresponding icon. They can be accessed by clicking on the appropriate icon.
The following visual aids are available:
The Answer Eliminator allows you to eliminate answers in Choice interactions. This is useful if there is a long list of answer choices, and you have problems processing so many options at once. By using the Answer Eliminator you can, for example, strike through certain options if you are sure they are incorrect, enabling you to consider the remaining ones with greater ease.
Answer Masking allows you to mask and unmask answers in choice interactions. It helps similarly to the Answer Eliminator above.
Area Masking allows you to mask parts of the item with a movable mask. Doing this may enable you to focus on the unmasked area with greater ease.
The Highlighter allows you to highlight parts of the text in an item.
The Line Reader allows you to visually isolate a line of text. Again, this may help you to focus on that particular line in a long text.
The Magnifier provides you with a movable magnifier tool. You might want to use this check certain parts of a long text.
The Zoom Tool allows you to zoom in on an area of an item. It has a similar use to the Magnifier.
