Interection design and thechnologies developed by brazilian healthtechs

Applications from IoT technologies - The Internet of Things has been used in the market of Brazilian startups that work in the field of health. Such technologies need to offer an efficient and intuitive interface so that the user can make decisions while performing tasks in the digital environment. Based on this assumption, the study aimed to identify the principles of interaction design in the elaboration of interface design for applications that use IoT technologies. To do so, it was sought in the literature review to conceptualize the terms Wearable, IoT, and the theoretical bases of usability criteria, interaction design, and interface design. With an exploratory and descriptive approach, the research presented a documentary survey of the situation of Brazilian healthtechs and how these companies apply IoT technologies in their products and services. To elucidate the theory, the procedure of analysis of the interaction design was used in an application for the treatment of epilepsy by the healthtech Epistemic. As a result, it was found the existence of a group of Brazilian healthtechs that invested in IoT technologies to promote health, well-being, and the fight against COVID-19 through their digital devices. By selecting Epistemic's IoT technology, it was possible to present how the interaction design appropriates the usability criteria to favor the communication process between the system and the user while evaluating the user's experience with the interface from the degree of satisfaction and efficiency in performing tasks.
