Not sure how much this buys you, but it makes sense where creating a android-like image to have emotion matching to group or task. We experimented only slightly with this in brand equity systems, mostly keeping the image smiling. It was suggested that we might include a quizzical or neutral face to indicate a more neutral position, but that was never integrated.
The Robot Smiled Back By Columbia Engineering
Columbia Engineering researchers have spent five years developing an autonomous robot with a face that mimics the expressions of nearby humans.
Development of the EVA robot began with the construction of its physical mechanisms, engineered as a disembodied bust with a blue-colored face that can express basic, as well as subtler, emotions via artificial muscles.
The researchers used three-dimensional printing to manufacture complex components that could fit into EVA's human-sized skull without losing functionality. EVA employs deep learning artificial intelligence to "read," then imitate, expressions on nearby human faces, and learned to mimic faces by watching videos of itself.
The robot eventually became capable of reading human facial gestures from a camera, and of responding by mirroring those facial expressions. .. "
