Question 1

Because accommodation of the lens and vergence angle of the eyes are controlled by muscles, one can expect that ______ will occur if individuals have to look at close images for a long period of time (as with computer displays).

Answer 1

Eye Fatigue

Question 2

Visual acuity is much higher in and around the fovea than in the peripheral visual field. An implication of this acuity function for Human Factors is:
1. present information through the tactile sense when possible
2. Present information auditorily when possible
3. It may be useful to signal an operator to look at a particular location when visually detailed information is being presented at that location
4. Assume that operators have less than 20/20 vision
5. All of the listed options

Answer 2

3. It may be useful to signal an operator to look at a particular location when visually detailed information is being presented at that location

Question 3

2. Dimmer
3. More colorful
4. Larger
5. Smaller

Answer 3

1. Brighter

Question 4
