Ensure graphics are used with purpose and do not clutter the screen.
Keep graphics simple, clear, and readable.
Graphics and explanation of graphics should be integrated to reduce working memory strain.
Use animations and transitions only to cue, signal, or highlight an important point.
Avoid flashing objects on the screen or provide a warning before the object starts flashing.
Use pop-up links purposely to direct users to other content, but make sure the video will pause if the pop-up is clicked.
Maintaining Focus
Be conscious of the length and objectives of the video.
Videos over three minutes with multiple objectives can cause cognitive overload.
If videos have multiple objectives:
Chunk the content and provide chapter stamps so viewers can jump to necessary information.
Make a series of shorter videos and create a playlist.
Present the most vital information first and conclude with supplementary information so users receive targeted instruction.
Beware the redundancy principle: when the words on a slide are simply read aloud, engagement drops off. Text slides should be summaries of the main points being made in the narration.
Be concise in your word choices as it keeps attention focused on the important concepts.
Highlight main points and actions with visual and auditory cues.
Ensure visual cues are large, clear, and obvious so users’ focus is directed accordingly.
Verbal cues are emphasized through tone and emphasis in the voice and by explicitly stating the importance.
Content should have the option of being self-paced (pause feature) or easy to navigate to give users required time to process information.
