This paper presents the "Letter Explorers" platform, an educational tool designed to support preschool children in their writing acquisition process. The platform was designed based on recognized pedagogical guidelines, structuring its activities into progressive levels of difficulty. The main focus is on learning letters and encouraging independent writing, respecting the motor and cognitive development of young children. Its features include real-time visual and auditory feedback, which helps correct and reinforce learning, as well as the possibility of personalizing activities based on the child’s name, a factor that contributes to motivation and engagement. The proposal aims to serve, especially, educational contexts in the interior of emerging countries, where access to quality digital solutions may be limited. Preliminary results indicate the potential of the tool to promote an interactive, inclusive and contextualized environment for learning to write in preschool education.

The Marczewski's Typology differs from other types of player profiles by addressing the gamification context. One form of self-evaluation to discover your player profile is through a simple questionnaire. So, in order to explore ways to increase user experience, this paper reports an experiment to develop an alternative test for self-evaluation by this typology. Named a Gamified Test, it is based on RPG genre and was compared to the original test. There was a quantitative and qualitative evaluation performed by computer students that showed differences and similarities between them.

This work proposes the development of a method that allows the use of smartwatch as a control for interactive films using continuous recognition of gestures and conducts a case study with the film "Black Mirror: Bandersnatch". We developed two prototypes to interact with interactive movies. The first one uses gesture recognition on the smartwatch screen. Thus, we created a set of gestures composed of straight lines that represent the actions in the interactive movie. In this prototype, the recognition of gestures is performed by the algorithm of continuous recognition of gestures, in this way, a gesture can be recognized before the user finalize, and action is sent quickly to the movie. The second prototype uses a touch of pressure in the smartwatch to control the film. Thus, the actions to be performed in the smartwatch that represents the actions in the interactive film is proposed, the recognition of the gestures is determined by the change of the values obtained by the accelerometer. The prototypes communicate with a simulation service responsible for running the movie. The prototypes were used in a study with users, as well as in usability and experience tests, and the results show that the method has the potential to be used in everyday users to control interactive films efficiently and effectively.
