Single orientation display limits options for fixed screens

Barriers to Experience with Processing Limitations

Printed material is not readily converted to alternate formats
Information is dense, not organized, and difficult to absorb
Instructions are not legible, sequential, clear, or concise
Environmental factors cause distraction and impede focus
Time constraints make it difficult to complete tasks
