ColorsInMotion

ColorsinMotion, is an application that supports the interactive and creative visualization and exploration of videos with a strong emphasis on color and motion properties, at the crossroads of information access, culture and digital art.

Complementary views, based on video’s content, their dominant colors and motion, like video loops, colored shapes, and slit scans, allow visualizing and emphasizing videos’ properties, helping to deal with their inherent complexity in more perceptive ways. At the video space level, the user can search, view, compare and interact with a selection of videos through different perspectives, emphasizing different properties and creating different views. From this level, the user can select and navigate to each one of these videos, to watch them and to further explore their individual features.

Videos are preprocessed and indexed into the system, according to different dimensions, but may come from several sources in the virtual or real world. The application can be used in a traditional setting with a screen, keyboard and mouse, or a touch screen, adequate in many contexts. But we are also developing more natural interaction modalities, based mostly on motion and color, adequate for installation settings and ambient interaction.

 

Some examples:

Fig 1: Video space presenting average scene video loops (left) and video slit scans (right) stressing motion properties in the videos.

 

Fig 2: Video space representing videos by their dominant color as a particle systems, where particles attract or repel in accordance to color similarity; in the right, videos’ traces are captured. Users take a chance on videos’ properties, or influence the process through interaction, influencing the aesthetics of the video space, where like colors tend to approach. Videos from different cultures will leave their own traces behind.
