Guideline 1.3 Adaptable: Create content that can be presented in different ways (for example simpler layout) without losing information or structure.


Meaningful Sequence

The sequences in which content is presented must be logical and intuitive. Be sure to title slides and scenes with meaningful names (e.g. avoid the default “untitled slide” or “scene 1”).  This example scene is called “Accessibility Demo” and the slides are titled “Welcome,” “Information,” and “Student Life.” Double click the title to edit.

Sensory Characteristics

Instructions provided for understanding and operating content should not solely rely on sensory characteristics like shape, size, spatial location/orientation, or sound. To help users navigate a Storyline object it is useful to create a how to navigate the material slide that explains how to move through the object.

Guideline 1.4 Distinguishable: Make it easier for users to see and hear content including separating foreground from background.

Use of Color

Colour should not be the only visual means of conveying information or distinguishing visual elements. If you have to draw attention to a slide or item use text and/or different shapes to convey information.

Audio Control
