[W6] Laws, time requirements, emotions & bodily sensations

1. Some types of mental processing are more challenging than others - use fitt's law to determine motor loads and evaluate to see, if the overall load can be reduced in order to improve ease of use

2. Expectations can change over time - and so do the time requirenments from the users. Ten years ago, a website which took 20 seconds to load was nothing really uncommon. Today, anything longer than 3 seconds can already lead to inpatient users, who might even drop from the page

3. If an ongoing process takes longer than one second, always implement a process indicator to show the user, what amount of time he most likely has to wait
