Emotional Intelligent Contents: Expressing User's Own Emotion within Contents [chapter]

Minyoung Kim, Kyoung Shin Park, Dongkeun Kim, Yongjoo Cho
2011 Lecture Notes in Computer Science  
Also, this emotionally intelligent content allows users to add their own emotion characters at run-time.  ...  This framework helps to create content that changes its elements (such as textures, color, light and sound) dynamically in response to a user's emotional state.  ...  Passive recognition of emotions is conducted by analyzing physiological signals, such as, PPG (photoplethysmograph), GSR (Galvanic Skin Response) and SKT (skin temperature).  ...

Appealing Virtual Humans [chapter]

Rachel McDonnell
2012 Lecture Notes in Computer Science  
However, humans are very experienced at observing the motion and appearance of other humans, and can be very unforgiving of minor errors in the form or movement of virtual characters.  ...  The aim being to guide developers in the creation of plausible characters that are considered appealing to viewers.  ...  Their movements can be created by artists, by programs (procedural animation), or recorded from real people using motion capture technology.  ...
