چکیده
math.RT/9808098 This short note is devoted to a second quantization of a classical picture described in [1]. 1.1. Interactive games and intention fields. Definition 1 [1]. An interactive system (with n interactive controls) is a control system with n independent controls coupled with unknown or incompletely known feedbacks (the feedbacks, which are called the behavioral reactions, as well as their couplings with controls are of a so complicated nature that their can not be described completely). An interactive game is a game with interactive controls of each player. Below we shall consider only deterministic and differential interactive systems. For symplicity we suppose that n = 2. In this case the general interactive system may be written in the form: (1) ˙ ϕ = Φ(ϕ, u 1 , u 2), where ϕ characterizes the state of the system and u i are the interactive controls: u i (t) = u i (u • i (t), [ϕ(τ)]| τ ≤t), i.e. the independent controls u • i (t) coupled with the feedbacks on [ϕ(τ)]| τ ≤t. One may suppose that the feedbacks are integrodifferential on t. Proposition [1]. Each interactive system (1) may be transformed to the form (2) below (which is not, however, unique): (2) ˙ ϕ = ˜ Φ(ϕ, ξ), where the magnitude ξ (with infinite degrees of freedom as a rule) obeys the equation (3) ˙ ξ = Ξ(ξ, ϕ, ˜ u 1 , ˜ u 2), where˜u i are the interactive controls of the form˜u i (t) = ˜ u i (u • i (t); ϕ(t), ξ(t)) (i.e. the feedbacks are on ξ(t) as well as on ϕ(t) and are differential on t). Remark 1. One may exclude ϕ(t) from the feedbacks in the interactive controls˜u i (t).

The Role of Avatar in Interactive Fictional World of Video Games
In third-person video games, players are able to move and progress in the interactive world of the game while watching their avatar from an external point of view. The purpose of this paper is to investigate the role of avatar in the interactive imaginary world of video games using double vision theory. This article is based on descriptive-analytical methods and the use of library data and imag...
متن کاملInteractive Art Analysis Based on Baudrillard’s Hyper reality Theory, a Case Study of Digital Interactive installation
The contemporary philosopher Jean Baudrillard, one of the postmodernism theorists, considers representation in the contemporary world as a factor in the disappearance of reality. In his view, the main feature of new arts is not the expression of artistic beauty, but communication with the audience and expression of the artist’s ideas. In interactive art, the presence and role of the audience in...
متن کاملDynamic system of strategic games
Maybe an event can't be modeled completely through one game but there is more chance with several games. With emphasis on players' rationality, we present new properties of strategic games, which result in production of other games. Here, a new attitude to modeling will be presented in game theory as dynamic system of strategic games and its some applications such as analysis of the clash betwe...
متن کاملComparison of the effectiveness of cognitive computer games and parent-child interactive games on problem solving and positive and negative affect of ten-year-old children in Shiraz
In recent years, research on increasing cognitive and psychological status through play has received much attention. For this purpose, there are two categories of game including interactive home game and cognitive game that the first run in the home environment and the latter is implemented as computer software to increase cognitive abilities. The aim of this study was to compare the effectiven...
متن کاملAdapting Image Texture Co-occurrence Analysis for Audio Texture Similarity
In this letter, we adapt a well-known technique of image texture analysis (grey-level co-occurrence matrix) to compute similarity between musical audio signals. Grey-level cooccurrence matrices estimate the joint probability of pairs of pixel values separated by a spatial displacement vector. Instead of using pixel grey-level values, we propose to use frame-based audio features, obtained either...
