Philosophy 3:

Scenario-based Algorithm

Adapts Various Experience

• ɑ and ß is the factor(%) representing user experience of

interaction and viewing experience separately, which is

defined via consumer survey

• ɑ, ß: weight of sInteraction & sView

• ɑ, ß value range comes from research result

• Different service/different area have different values

ɑ 0.66 0.71

ß 0.77 0.77
