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.

9. Discussion (Possible utilizations)
Audience control;
Feedback data collection…
Content contextualization;
Adapts the content according to the emotion…
Use with autistic people;
Affective computing can be used for treatement…
Use for HCI;
Reducing the frustration of the user…

10. Final Considerations
• Contributions:
• Investigate Affective computing and
Computer Vision concepts has aplied to
improve interactivity for Digital Television.
• Exemples of uses like audience control and
context of content for Digital Television.
