Studying the acceptance and usage of technologies has become one of the most significant fields in software engineering domain. In order to explain the individuals' usage behavior towards technologies, many theories and models have been proposed over the years. This research paper focuses on reviewing a group of ten technology acceptance theories and models by studying their structure, evolution stages, and their strengths and weaknesses points. These theories were analyzed and classified into two main types depending on their development method and scientific field which they were developed in. This study reveals that these theories are almost similar in their structure, but different in explaining the behavioral intentions of technology. It considers that the best theory should be comprehensive and less complexity according to the number of the constructs and moderators which represent their structure. This will make the theory more understandable and applicable especially for studying the acceptance behavior for any new technology.

2. Theories And Models Of Technology Acceptance

As mentioned before, this paper presented ten of the most famous, and widely used technology acceptance theories and models. These theories were developed to study the acceptance of technology by individuals and to show their ability to adopt new technology depending on the concepts of the behavioral science in psychology and sociology and their effects on the usage of the technology. These theories have been developed over the years and resulted from the extension of each other. Thus, the most important and famous used ten theories are reviewed as follows: The Theory of Reasoned Action (TRA) (Ajzen and Fishbein, 1980), which was extended to the Theory of Planned Behavior (TPB) (Ajzen, 1985), which also had an extension to the Decomposed Theory of Planned Behavior (DTPB) (Taylor and Todd, 1995c). The information systems had a contribution to the existence of the Technology Acceptance Model (TAM) (Davis, 1986), which is an extension of TRA; that also has an extension to TAM2 (Venkatesh and Davis, 2000). In addition to combination form of TAM and TPB (C-TAM-TPB) (Taylor and Todd, 1995a).
