Abstract: A method to guide and constrain an Artificial Intelligence (AI) engine in generating and distributing notifications aimed at re-engaging users of an online learning platform is disclosed. It begins by collecting user data incorporating user profile details, user engagement data, and user performance data such as study goals and interaction logs. After analyzing the user data, notification timings are determined to align with each user's educational objectives. The process involves generating prompts to direct the AI engine in creating personalized video messages featuring virtual characters in correspondence to users' previous learning sessions. These prompts are then utilized to integrate the virtual character into video notifications, which are shared with users. The notifications include real-time interactions with the virtual character, designed to motivate and encourage users, thereby enhancing their ongoing participation and retention within the online learning environment.

Abstract: An automobile bumper including an isolator including one or more step surfaces integrally formed on the isolator. The step surface(s) may provide a gripping surface for permitting a user to step on for loading and unloading objects from the automobile. A fascia cover may be attachable to the isolator and include a cutout for allowing the step surface(s) to protrude through the cutout to prevent direct contact of the user's foot with the fascia.
