Abstract

Methods and systems for trajectory and intent prediction are provided. The methods and systems include operations comprising: receiving an observed trajectory of a user and user behavior information; processing the observed trajectory by a machine learning technique to generate a plurality of predicted trajectories, the machine learning technique being trained to establish a relationship between a plurality of training observed trajectories and training predicted trajectories; adjusting the plurality of predicted trajectories based on the user behavior information to determine user intent to operate a target access control device; determining that the target access control device within a threshold range of a given one of the plurality of predicted trajectories; and in response to determining that the target access control device is within the threshold range of the given one of the plurality of predicted trajectories, performing an operation associated with the target access control device.
