Avaliação da comunicabilidade do sistema odontológico de Quixadá-CE

Abstract

The human-computer interaction - HCI is an area of computing responsible for producing interactive computing systems with good usability. It is a new discipline concerned with the design of computational systems efficient, safe, functional and pleasing to users. The HCI studies are concerned with understanding how people use computerized systems in order to design systems that best meet the goals and needs of users, can help in the process of developing systems, because this way you can judge the quality of user interaction with the system. One of the concepts studied is communicability, where the designer should express themselves properly through the interface, ensuring that the user can predict and understand what to do in the system to perform tasks alone, efficiently, easily and with a two-way communication between user and system. Thus, the user understands the message and the designer can interact with the system, and the system responds to user actions stating what is going on, preventing the user becomes distressed and unhappy. The objectivity is a concept derived from the Semiotic Engineering, HCI theory that allows us to understand the phenomena involved in the design, use and evaluation of an interactive system. The Evaluation Method of communicability is based on this theory it is a method essentially qualitative, where the evaluator observes the interaction details in order to find breaks in communication and associated "natural expressions" to these disruptions. From the ruptures identified the evaluator analyzes the communication problems identified and reconstructs the metamessage pointing their problems. This study aims to evaluate the communicability of the SISO system - System Dental Quixadá, a system developed by the NPI - Center for Informatics Practices UFC Quixadá, based on a development platform, the framework Entities, which enables developers to worry only at the domain classes, thus generating an automated interface.
