Technology Acceptance Models (TAMS) and their Relations to ICT Adoption
The TPB might not be totally fit into technology acceptance in organizations unless certain elements are introduced. In the light of this, additional variables, such as perceived expressiveness, perceived enjoyment, perceived ease of use, and perceived usefulness have been introduced to TPB as determinants of attitude to optimise its prediction of intention-actual use behaviour towards technology to develop TAM. In other words, TAM model posits that if a user perceives that a given technology is useful, the person will hold a positive use-performance and strong intention based on his or her belief about it. Findings show that users are likely to accept application of technology when they perceive it easier for them to use, thereby inducing a positive attitude to their minds. However, some scholars have called for extension of TAM to meet the needs of different research settings, which has been discussed in other chapters of this book.
