Query \(\PageIndex{1}\)
Overall Usability
Requires Alternative Activity:
- This activity is not usable by some users.
Important Reminders
This activity can be difficult to use with the keyboard and for users with various types of disabilities, including users of screen reading software. Consider including an alternative version with several pictures from different perspectives, each with a accessible text that provides a description for all users of the meaningful visual information.
Visible Indication of Focus
After the full screen button, there is a focusable element that does not have a visible indication of focus. There is a visible indication of focus for the rest of the activity.
Color Contrast
The visible indication of focus does not have good contrast. The visible indication of focus is a thin white or a thin black line. Users who require a visible indication of focus with more contrast may use assistive technology. The color contrast of meaningful visual elements and text with backgrounds must be ensured manually by the content author.
Keyboard Usability
The activity is not usable with the keyboard. The activity is difficult to use with the keyboard because changing the keyboard focus may abruptly change the scene, which includes unexpectedly moving the location of the buttons. When an information window is closed, the keyboard focus does not return to the information button.
No Keyboard Traps
There are no keyboard traps.
Magnification
The activity supports both magnification up to 200% and reflow of content with magnification up to 400% without a loss of content or functionality and without requiring horizontal scrolling.
Usability with Screen Reading Software
The activity is usable with screen reading software. H5P does not provide an option to include longer descriptions for meaningful images that require alt-text descriptions of more than 150 characters. When adding meaningful images, content authors must include separate text immediately after the image. The text must include a label indicating it is a description of the associated image. Begin the text description with a heading level 2 (which may be the same text as the label). Content authors must provide users with instructions that longer descriptions of meaningful images may be found by selecting the separate button labeled as a description of an image.
