Abstract: An apparatus that transfers object motion in a source space to a target space is provided. The apparatus defines a mapping function from the source space to the target space based on feature points of the object-positioned source space, and feature points of the object-represented target space; determines a target root position corresponding to a root position of the object based on the mapping function; determines a target direction corresponding to a direction of the object, based on the mapping function; determines a target main joint corresponding to a main joint of the object based on the mapping function; determines a target sub-joint excluding the target main joint in the target space based on unique joint information of the object; and generates data representing the object motion in the target space by modifying a pose of the object in the target space to match the target main joint.

Abstract: Disclosed are a spheroid array and more particularly, a droplet trapping structure array capable of isolating all or selected spheroids into an isolated droplet array environment and the use thereof. The droplet-trapping structure array and the method and device for transferring spheroids using the same have the advantages of transferring droplets or spheroids with very high efficiency and very small variation between users by simply contacting two arrays. The spheroid transfer method and device enable mass-production of spheroid arrays in an isolated environment. In particular, the droplet trapping structure array and the spheroid transfer method can be useful for the treatment of spheroids with various reagents and the exchange of culture media.
