    摘要： Systems and methods are provided for estimating 3D poses of a subject based on tactile interactions with the ground. Test subject interactions with the ground are recorded using a sensor system along with reference information (e.g., synchronized video information) for use in correlating tactile information with specific 3D poses, e.g., by training a neural network based on the reference information. Then, tactile information received in response to a given subject interacting with the ground can be used to estimate the 3D pose of the given subject directly, i.e., without reference to corresponding reference information. Certain exemplary embodiments use a sensor system in the form of a pressure sensing carpet or mat, although other types of sensor systems using pressure or other sensors can be used in various alternative embodiments.

    摘要： An approach to designing a structural combination of multiple materials includes determining, using a physical simulator, simulated measurement data for a first plurality of simulation designs. Each simulation design characterizes a structural combination of a plurality of materials. The simulated measurement data for each simulation design provides a simulation of physical qualities of the design. A subset of the simulation designs is selected based on the simulated measurement data for said simulation designs to yield a set of fabrications designs. This set of fabrication designs is provided for fabrication of a set respective physical samples. A set of physical measurements is received for the set of physical samples. Each physical measurement for a physical sample providing measurements a plurality of physical qualities of the sample. The physical simulator is reconfigured using a set of fabrication designs in association with respective physical measurements of physical samples fabricated according to the fabrication designs.
