Phase 3 includes investigations of the
social, psychological, and physical effects
of the medium. How much time do people
spend with the medium? Does it change
people’s perspectives about anything? What
do the users of the medium want and expect
to hear or see? Are there any harmful effects related to using the medium? In what way, if
any, does the medium help people? Can the
medium be combined with other media or
technology to make it even more useful?
