The development of a real-time wearable motion replication platform with spatial sensing and tactile feedback

The human body motion is a very important mean of expressing a person´s emotion, knowledge and experience, as well as an effective communication tool in inter-personal interaction. We aim to provide a methodology for seamless integration of movements between the real human and the virtual one in Co-space, enabling motion replication in both directions. We developed the prototype systems consisting of a wearable InterfaceSuit that enables human motion replication and learning in Co-space, and a human-to-human motion replication methodology with multi-modal feedback mechanisms. We employed the wearable inertial sensors and optical linear encoder sensors to capture human body movement, and designed the haptic guidance device - 3 Dimensional Orientation Guide prototype with polyester tactor holder and elastic arm bands made of light-weight material for portability. We integrated sensing and feedback devices to build up a multi-resolution upper arm interfaceSuit to capture finger movements and arm movements (wrist, elbow and shoulder) and as well as wearable vibrotactile devices, sensor systems, and the control system for multimodal feedback.
