Final answer:
For adequate trainee viewing, visuals should be clear and large enough for all audience members to see. Consistency in visual style and attention to accessibility are also important.
Step-by-step explanation:
The rule of thumb for adequate trainee viewing of both static and dynamic visuals involves several important considerations. It is essential to ensure that visuals are large enough for the audience to see without strain. Whether it's a graph, chart, image, or video, the media must be clear, concise, and of high quality to avoid frustrating your audience.
Additionally, maintaining a consistent visual style and providing adequate space and time for the audience to absorb the media is crucial. It is also important to provide space and time for the audience to engage with the media and consider accessibility for all viewers. By following these guidelines, you can create visuals that effectively convey your message to the trainees.
One must also consider accessibility in presentations. This means accommodating the needs of those who may rely on interpreters or who are visually impaired. For instance, accessible presentations might include audio descriptions for images or captions for videos to aid those with hearing difficulties.
