Augmented-Reality (Playware Playground) Games Research

Description

The Playware prototype playground consists of several building blocks (i.e. tangible tiles) that allow for the game designer (e.g. the child) to develop a significant number of different games (e.g. Bug-Smasher, Space-Invaders) within the same platform. The overall technological concept of Playware is based on intelligent physical identities (tiles) that incorporate processing power, communication, input and output, focusing on the role of the morphology-intelligence interplay in developing game platforms.

The principal goal here is to construct user models of a class of game-playing experience. Specifically, the aim is that models can predict the answers to which variants of a given game are more or less “fun.” This approach is referred to as Entertainment Modeling. Entertainment generated by a physical game experience is captured through features extracted from user-game interaction and user’s physiological state and feature selection is used for choosing the appropriate set of features that successfully predict expressed entertainment preferences. The output of the constructed model is a real number in the range [0, 1] such that more enjoyable games receive higher numerical output. This basic approach of entertainment modeling is applicable to a variety of games, both computer and physical using features derived from physiological data and/or from the interaction of player and opponent measured through game parameters.

The proposed approach can be used for adaptation of the game’s entertainment features (challenge, curiosity) according to the player’s individual playing and physiological features in real-time. The key to this is the observation that the models relate features to an entertainment value. It is therefore possible in principle to infer what changes to game features (given embedding of the features in the model) will cause an increase in the entertainment value of the game, and to adjust game parameters to make those changes.
