I used the Chrome No-Coffee extension and applied it the Endeavor Course on Everfi that I reviewed using the WCAG Accessibility Guidelines. The main improvements that this resource could make are as given below:
Colour deficiency; none of the settings affected the learner’s ability to view and access materials. This was extremely effective as the contrast of colours worked so well that in any of the settings the images were still well defined.
Blur; Gave me an instant headache and writing was not visible after 3. There is narration in this window which verbally describes the activity and information.
Contrast loss; due to the bright colours, this was still visible on max 50.
Glare; instant headache and writing was not visible from 1-6. There is narration in this window which verbally describes the activity and information.
Ghosting; only lasted to 3 before it became unreadable.
Snow; made no real impact other than a small patch in the top left hand corner. It was annoying more than anything.
Cloudiness- was not as bad as I thought. Managed to get 10 12. Again the bright colours work in its favour.
Flutter; made me feel sick. At 55 it was more prolonged and the screen shook everywhere.
Blocked Visual Field
I used the setting of 50 (midway) to compare.
Central; a bit blurry in the middle of the screen but still able to see. Made me feel sick.
Peripheral; Could see the centre of the screen not the outer edges. Made the image in the centre sharp.
Corner; Top left corner masked.
Side; left hand side impossible to see.
Large Spots; Made the screen brighter but still visible
Overall the main improvements would be for visually impaired. If there was some way for learners to drag content into the section of the screen that is accessible to them then this would would be fully accessible. The bright, contrasting colours creates a good balance that is visible for all learners. The audio narration and supporting visual text help support visually impaired students but does not make this 100% accessible. Learners could use multiple monitors or enlarge the web page to suit their needs.
