Table 1: Studies on Smartwatch Adoption/Acceptance. Based on the previous table, it seems that studies on the adoption of smartwatches used one unified tool, which is the questionnaire in which TAM is considered a concrete part of the model [33; 34; 35]. The only exception to the previous assumption is a study carried out by [32] where UTAUT2 as an extended model is added. The TAM model seems to affect the adoption in two different ways. The first one is related to the perceived usefulness, which is a crucial element that may be affected by various extended factors. The other is perceived ease of use, which is a decisive element that can be connected to fashion and innovativeness as an external factor; thus, they affect the adoption of smartwatches significantly [33; 34; 35].
