Resumo
Smartwatches are wearable and smart watch-shaped devices that aim to facilitate the daily
lives of users, however, as they have small screens, the traditional mechanisms of interaction
with touch-sensitive screens may not be efficient on these devices. Thus, it is important to
develop new interaction methods that use the touchscreens of smartwatches.
Therefore, in this work a method was developed that uses simple gestures, based on geometric
shapes with continuous recognition of gestures on smartwatches touchscreens as an interaction
mechanism. The results obtained with usability and/or experience tests of the method
developed in case studies carried out in four segments are presented: text input in
smartwatches and in virtual environments, interaction with platform games, video players and
interactive movies and home appliances. During the development of this work, adaptations were
made to the continuous gesture recognition algorithm: the recognition step was parallelized,
which allows using threads to calculate the gesture probabilities; A technique was developed
that allows detecting the change in gestures, allowing the user to initiate a new gesture without
having to remove their finger from the screen. The results show that the continuous gesture
recognition algorithm can be used in smartwatches and that with a small set of gestures it is
possible to perform different actions. Thus, the developed method expands the possibilities of
interaction with devices and environments using the smartwatches touch-sensitive screens and
continuous recognition of gestures.
