The motion is feeling better but it's still in uncanny valley. Cool but creepy!
You can read the technical paper here:
// Disney Research - Realistic and Interactive Robot Gaze
"We present a general architecture that seeks not only to create gaze interactions from a technological standpoint,but also through the lens of character animation where the fidelity and believability of motion is paramount;" -Walt Disney Imagineering - Advanced Development, Glendale, California, USA
Harald Siepermann was a fantastic character designer and storyartist. I started following his blog in the early 2000's until he stopped posting in 2011. I highly recommend you check out his blog and website. There are tons of great stories, pictures and artwork from various productions he worked on over his 30 year career. Below is an old interview that I found recently. Sadly, it looks like it was posted just after he passed in 2013.
