Question
A user needs to read documentation on a device while walking around outdoors in bright sunlight. Which of the following is the best type of device for this purpose?
- A. Laptop
- B. Tablet
- C. E-reader Correct
- D. Smartphone
Explanation
E-readers use electronic ink (e-paper) screens that reflect ambient light instead of emitting it, so they stay readable in direct sunlight and are light enough to carry while walking. Laptops, tablets and smartphones use backlit LCD or OLED screens that wash out in bright sunlight, and a laptop is awkward to use while walking.
