Scenario triggering and interaction based on target positioning and identification

Abstract

A method for scenario triggering and interaction is disclosed. One or more camera devices () are used to monitor a target object () in a scene (). A target object vector () is generated from captured images of each camera device () to represent a line of sight from the camera device () to the target object (). A target object position () in the scene () is then determined from an intersection of the target object vectors (). The target object position () is compared with a task triggering region () in the scene () to trigger a pre-determined task when the target object () is within or around the task triggering region (). For example, the target object () may be a human user and augmented reality contents are presented to the human user when the human user is detected to be within or around the task triggering region ().
