NOVELTY - The attribute building system (100) has a training selection component (130) that determines a level of training for the character based at least in part on a training history of the character, selects the training session from among multiple different possible training sessions, based at least in part on the character's training history. The training selection component presents the training session on-screen. A performance indicator display (160) presents at least one of a grade, score and final result indication of the training session on-screen.    USE - Attribute building system for developing and improving attributes of characters or pets in virtual environment. Uses include but are not limited to developing and improving strength, speed, agility, intelligence, creativity, style, streets-smart, safety-awareness, grooming, cooking, and manners.    ADVANTAGE - Allows users to have more input and influence in customizing their virtual characters' profile by developing their attributes. Jobs, tasks, classes, and sessions, as well as competitions can be created that emphasize one or more attributes to facilitate encouraging users to have their characters learn, master, and test new skills.    DETAILED DESCRIPTION - A real-time monitoring component (120) receives a training request for a training session associated with at least one attribute and determines whether a minimum real-time threshold value has elapsed since a previous training session in order to permit further processing of the training request. The training request is submitted on behalf of a character. A health analysis component (110) evaluates a health status of a character to determine whether the character is able to participate in the training. Successful completion of the training session facilitates advancement to more difficult levels of training sessions for at least one attribute. The attribute increases social status and value of the character in the virtual environment. An INDEPENDENT CLAIM is also included for an attribute building method for characters in a virtual environment.    DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of an attribute building system that facilitates developing and improving a virtual character's attributes to enhance interactive play and status within an online social environment.
