Document Summary

Considerations: where to place the options= fitts". Law (simple reaction time: number of choices= hick"s law (choice reaction time) Reaction time: the amount of time it takes to respond to a stimulus: simple reaction time: 1 stimulus, 1 reaction (ie. traf c light, choice reaction time: several stimuli, 1 reaction or 1 stimulus, several reactions (ie. tetris) Hick"s law: the more stimuli there is to choose from, the longer it takes to make a decision. *limitation= hick"s law is already assuming we know what we are looking for. The 5 senses: taste, touch, sight, smell, sound. We actually rely on sight the most when interacting with our environment, almost to a fault. As we increase the speed of movement, the likelihood of error increases speed of movement and error are directly proportional. If you close your eyes, error increases and does not get any better with changes in eye movement speed (plateaus)
