Abstract: A communication method in an Internet of Things environment is for transmitting an outgoing message to the Internet. The communication method includes a device status acquiring step, a switch process determining step and a message transmitting step. The device status acquiring step is performed to obtain a signal connecting status between a demand device and a first base station. The switch process determining step is performed to determine whether a switch process of the demand device is activated according to the signal connecting status. In response to determining that the switch process of the demand device is activated, establishing a first communication path to connect the demand device, a target device, a second base station, and the Internet. The message transmitting step is performed to transmit the outgoing message from the demand device to the Internet via one of the first communication path and the second communication path.

Abstract: Disclosed are methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing interaction behavior detection. One method includes obtaining a depth image from a depth camera disposed above a rack, and a filming range of the depth camera covers an outer edge of each shelf in the rack and an aisle. A foreground images associated with a moving object from the depth image is extracted. Spatial coordinates of the moving object are obtained based on the foreground image. An object on a shelf in the rack that is physically contacted by the moving object is determined based on comparing the spatial coordinates of the moving object with spatial coordinates of the shelf, where the spatial coordinates of the shelf is determined based on a background depth image captured by the depth camera at a predetermined angle unobstructed by the moving object.
