  The study uses bibliometric as well as content analysis to determine the
current situation regarding the application of technology adoption models
(i.e., the Technology Acceptance Model, Unified Theory of Acceptance and Use of
Technology, and Innovation Diffusion Theory) to the smartphone market that also
includes smart wearables. Hereby the author would like to determine the
connection between smartphone usage and adoption models and enrich literature
by defining state-of-the-art tendencies and approaches. To achieve the goal,
the author applied a two-stage approach: in the first stage, 213 articles were
analyzed using Citation and Bibliographic coupling tools in VOSviewer (1.6.20).
The papers were selected from the Scopus database and the search of the papers
was conducted in the fields of Economics, Business, and Computer technologies.
In the second stage, the author conducted a brief literature review of the most
influential papers. The results illustrate the situation regarding the
implementation of different models in the case of smartphone adoption. Content
analyses of the most influential papers were applied to explain and enrich the
results of bibliometric analyses as well as determine research gaps and future
research development.
