Using a VR or MR headset while lying down is uncomfortable, and turning your head is hard when it rests on a pillow. HeadTurner is a device that assists shoulder and head actuation, so you can look around comfortably and see more of the scene from a reclined position.
I worked on it at the NTU HCI Lab (advisor: Prof. Mike Y. Chen) as a co-author. I helped design the device, implemented the EMG analysis, ran the user studies and wrote the related-work section of the paper.
