摘要： In illustrative implementations of this invention, light sources illuminate a surface with multi-spectral, multi-directional illumination that varies in direction, wavelength, coherence and collimation. One or more cameras capture images of the surface while the surface is illuminated under different lighting conditions. One or more computers take, as input, data indicative of or derived from the images, and determine a classification of the surface. Based on the computed classification, the computers output signals to control an I/O device, such that content displayed by the I/O device depends, at least in part, on the computed classification. In illustrative implementations, this invention accurately classifies a wide range of surfaces, including transparent surfaces, specular surfaces, and surfaces with few features.

摘要： A computing system configured to perform operations that identify user movement(s) as upper-body exercise(s). The operations can include obtaining sensor data generated by one or more sensors of a footwear device worn by a user, the one or more sensors positioned in one or more positions of the footwear device, the sensor data associated with one or more movements performed by the user. The sensor data can be input into a machine-learned exercise identification model. Exercise identification data can be received as an output of the machine-learned exercise identification model. The exercise identification data can identify the one or more movements performed by the user as one or more upper-body exercises performed by the user, the exercise identification data comprising one or more exercise characteristics associated with each upper-body exercise of the one or more upper-body exercises performed by the user.

摘要： The claimed subject matter provides a system and/or a method that facilitates detecting and identifying objects within surface computing. An interface component can receive at least one surface input, the surface input relates to at least one of an object, a gesture, or a user. A surface detection component can detect a location of the surface input utilizing a computer vision-based sensing technique. A Radio Frequency Identification (RFID) tag can transmit a portion of RFID data, wherein the RFID tag is associated with the surface input. A Radio Frequency Identification (RFID) fusion component can utilize the portion of RFID data to identify at least one of a source of the surface input or a portion of data to associate to the surface input.
