There has been significant progress in the graphical realism of digital humans in recent years. This work investigates the realistic portrayal of emotions beyond facial expressions by analysing how skin colour changes when expressing different emotional states. The study combines existing knowledge from old painters, photogrammetry data, thermal imaging, and skin colouration maps to create an artistic guideline to portray emotions realistically, resulting in the proposal of a set of colour maps representing the six basic emotions. By using skin colour changes to represent emotional states, the proposed colour maps offer an alternative workflow for portraying emotions. During the experiment of this research four of these proposed colour maps, which represent neutrality, anger, disgust, and happiness, were preferred over traditional alternatives in terms of realism perception and likeability. The findings have implications for the development of digital human technology, particularly in the creation of more realistic and expressive digital characters.
Can computers talk like humans? Look like humans? Behave like humans? Project Virtual Humans in the Brabant Economy (VIBE) focuses on developing and testing virtual humans to make this happen. The virtual humans developed by VIBE will be able to communicate with normal people in a natural way, both verbal and non-verbal, and deliver a valuable contribution to the training of healthcare professionals. The agents developed by VIBE can be used in any training simulation in various instances, including virtual, mixed and augmented reality.VIBE agents are designed to also allow customization for other domains to enhance training and education programs even beyond the healthcare domain.Funding:EU EFRO, Province of Noord Brabant, municipalities.
