Movies are one of the foremost sources of entertainment, in individual and social contexts. By combining diverse symbol systems, such as images, texts, audio and narration to create stories, they often engage the viewer’s perceptually, cognitively and emotionally. Technological advancements are enabling the access to enormous collections of videos and movies over the Internet, in social media, and through video on demand services, becoming a growing entertainment activity on the web and iTV. The development of video content-based analysis and classification techniques is also allowing the access to more information about or contained in the movies, demanding for new ways to search, browse and view videos and movies in this scenario. This work presents different mechanisms to access, explore and visualize movies based on their emotional properties, either expressed or felt by viewers. In that way, were designed two prototypes. iFelt, where the mechanisms applied focus on felt emotions to interact with movies and movie scenes. And movieClouds, a prototype that uses felt emotions also, but focus on expressed emotions on movies conveyed in the different tracks or perspectives of its content, especially audio and subtitles where most of the semantics is expressed, to access, explore and visualize movies. Both prototypes were evaluated with users to get insights and feedback from them, and check if it useful, satisfactory and ease to use. Besides the difficulty to learn the new concepts at first, the results were quite encouraging. In fact, the users love the idea of taking advantage of emotional properties to interact with movies on features such as the timelines, movies space, and movie scenes.
