The method used is a comprehensive literature review of the previous two best practice models, TRI and UTAUT. The results showed that there were 13 hypotheses and 10 constructs from the proposed combination model. The entire construct is optimism, innovativeness, discomfort, insecurity, performance expectancy, effort expectancy, social influence, facilitating conditions, behavioral intention and use behavior.
