The increase in the number of users of the Smart TVs has been very
fast: just between 2016 and 2017, there has been an expansion of
more than 7 million users. At the same time, considering the global
estimates referring to the increase of longevity, it can be predicted
a gradual increment of elderly people utilizing these devices in the
coming years, which highlights the importance of perfecting their
quality of use. In this context, the objective of the present study is
to evaluate what are the main challenges elderly people face while
using Smart TVs, focusing on a specific application, known as NET
Now. To conduct this study, the focus was on the quality of use
of communicability, analysed through the application of two evaluation
methods: the Semiotic Inspection Method, applied by one
evaluator, and the Communicability Evaluation Method, applied to
six participants aged between 60 and 80 years. It has been observed
that both methods indicated problems related to different communicability
breakdowns, emphasizing the importance of this kind
of evaluation in order to improve the quality of use of interactive
systems.
