Abstract: An example method includes obtaining, from a plurality of audience members that are recipients of media content, sentiment data indicating reactions of the plurality of audience members to the media content. The media content includes at least one of audio and video, and the sentiment data includes commentary from the recipients regarding the media content or physical reactions of the audience members to the media content. At least one aggregate sentiment of the plurality of audience members is determined based on the sentiment data. At least one the following is performed: transmitting an indication of the at least one aggregate sentiment to a computing device, and augmenting the media content to indicate the at least one aggregate sentiment to the audience members.

Abstract: The present invention discloses a back-propagating intersection collision avoidance (ICA) system for preventing two or more vehicles from colliding at an intersection. The ICA system can calculate predicted positions of the two or more vehicles in the near future, and both the current and future positions can be broadcast to surrounding vehicles using vehicle-to-vehicle communication. For each vehicle, a set of states, for example position, speed, acceleration, and the like, where a collision is imminent can be identified using state information for a local vehicle, a remote vehicle, and a known collision zone for the intersection. If the current states of the vehicles are determined to be in danger of entering the collision zone, the ICA system can control the vehicles to perform evasive driving maneuvers and/or alert the drivers.
