RESUMO

The content-based image retrieval (CBIR) is a challenging area of the computer science that has been growing in a very fast pace in the last years. CBIR systems employ techniques for extracting features from the images, composing the features vectores, and store them together with the images in data bases management system, allowing indexing and querying. CBIR systems deal with large volumes of images. Therefore, the feature vectors are extracted by automatic methods. These systems allow to query the images by content, processing similarity queries, which inherently demands user interaction. Consequently, CBIR systems must pay attention to the user interface, aiming at providing friendly, intuitive and attractive interaction, leading the user to do the tasks efficiently, getting the desired results, feeling safe and fulfilled. From the points highlighted beforehand, we can state that the human-computer interaction (HCI) is a key element of a CBIR system. However, there is still little research on HCI for CBIR systems. One of the requirements of HCI for CBIR is to provide a high quality interface to allow the user to search for similar images to a given query image, and to display the results properly, allowing further interaction. The present dissertation aims at analyzing the user interaction in CBIR systems specially suited to medical applications, evaluating their usability by applying HCI techniques. To do so, a case study was employed, and the results presented
