DESCRIPTION
This article discusses the concepts of using Digital Television Affective Computing and Computer Vision. The proposal involves the union of some techniques such as capturing facial expressions through a video camera, use of accelerometers in ball and touch holograms to work a certain level of interactivity with the viewer. Some examples of uses of the proposal in question are described, such as control of the hearing, background content, among others.
