Abstract: Techniques for placing content in metaverses in environments contextually compatible with the content are disclosed. A system trains a machine learning model to identify virtual environments compatible with content based on attributes representing contexts of the environments. Using the machine learning model, the system determines an environment for a target content item. The system selects the particular environment for placement of the target content item based on the compatibility score.

Abstract: Techniques for determining content for presentation to users in particular metaverse environments based on behaviors of the users in the environments. A system monitors behavior of a user's avatar in metaverse environments. Based on the behaviors, the system generates an environment-specific user profile. The system selects one of the environments for displaying content based on the environment-specific profiles while the avatar of the user is within the environment.

Abstract: Systems are disclosed for determining contextual segments for targeting contextual advertising in metaverses. The system can deploy an observer avatar in a metaverse to capture information inside a portion of a metaverse from behaviors and interactions of a target user avatar. The observer avatar can capture audio, video, images, and text perceived by the observer avatar in the area of the user avatar, along with metadata describing the captured information. Using the captured observations, the system can determine contextual segments classifying the portion of the metaverse. Using a library of the contextual segments, advertisers can distribute contextually targeted advertisements.

Abstract: Systems, methods, computing platforms, and storage media for detecting a potential collision with a vulnerable object are described. Exemplary implementations may include a detection system coupled to the vulnerable object comprising a main unit, the main unit comprising a power device, a housing, a central processing unit, an internal memory device or a storage device, at least one of an optical sensor, a laser, an accelerometer, and an alarm, a wireless transmitter for exchanging data with a first object, a computing device, or another vulnerable object, and a communication device for communicating with a radar unit or a computing device. The radar unit comprises one or more antennas and detects the first object using millimeter wave or Extremely High Frequency radio frequencies and transmits an indication of the first object to the main unit via the wireless transmitter or the communication device.

Abstract: Systems and methods for direct e-commerce ordering on external websites is disclosed. Consumers may post a comment on the external website to initiate the purchase of an item or service from the corresponding e-commerce system. The system may scrub the comment system of the external website to locate the direct ordering request. The system may transmit the direct ordering request to the corresponding e-commerce system. The e-commerce system may process the direct ordering request to determine the associated consumer that submitted the request, and may process payment and complete the transaction.
