5. Chapter 3 Anthropometrics
Posture
Haptic and kinesthetic and the other 5 senses
Fitts law

6. Ch 3 Fitts Law [10 min.]

7. Fitts Law Time to move = Implications Constant + rate * ID
log2(2d/w)
70 log2(d/w + 0.5)
Implications
Make d short
Make W large
W on edge is infinite
Make d 0
Make constants small (e.g., pointing finger vs. complex joystick; clean mouse vs. rat)
Move to keystroke
