Three models stand out as the most widely applied -TAM,the technology acceptance model,including perceived ease of use and perceived usefulness. -TRA the theory of reasoned action. A model predicts behavioral intention(attitude toward to behavior and subjective norm). -TPB. the theory of planned behavior. It is added another factor, perceived behavioral control to the TRA.

Per E. Pedersen(2007) extend the TAM with subjective norm and behavioral control into a decomposed TPB(subjective norm and behavioral control). Imsook Ha etc(2007) extended TAM to include an emotion variable and measured the moderating effects of gender, age, and prior experience to examine mobile game adoption. The results revealed that the effect of perceived enjoyment was very important,and age can be key moderator of game acceptance.
