ASSIGNMENT

1. Repeat all experiments by using mouse with non-preferred hand and compare the results.

2. Repeat all experiments with minimum as well as maximum mouse sensitivity and compare the results. To check and change your mouse sensitivity refer to the URL at the end of this page.

3. Try performing the experiment while carrying out some secondary task . This divides your attention. Compare time and error-count from the results.

4. Repeat the same experiment by changing the brightness and resolution level of your screen and compare the results.

5. Try to find optimal mouse sensitivity for young , middle and old aged people for maintaining same error rates.

6. Do you think this exercise will help you design screens for the elderly and the people with unsteady hands?

7. Explain how you will make use of this knowledge in designing a digital game?

 

Mouse sensitivity is the speed of a mouse pointer and how fast it moves on the screen. With increased sensitivity, the mouse moves faster and requires less effort to get across the screen. With low mouse sensitivity, a mouse moves slower and requires more effort to get across the screen but offers better precision for users not familiar with a mouse.
