From Brain Waves to Game Design: A Study on Analyzing and Manipulating Player Interest ... - 0 views

  •  
    From the abstract: "Our goal is to create a better understanding on how to design encounters that affect interest levels in linear FPS games. Specifically, how exactly a player's interest levels can be raised intentionally. To accomplish this, we developed a method for measuring and comparing player interest levels based on electroencephalogram (EEG) data measured using a "Neurosky Mindset" unit, which is a commercially available EEG device. We measured player EEG data for the first 4 levels of the FPS game "Call of Duty: Modern Warfare 2" and calculated player interest levels for the entire length of gameplay. By referring to recorded gameplay videos, we were able to associate each increase in interest levels for each player to a specific point in game. From this data, we found and isolated points in each level where most players showed a rise in interest levels, and discovered that certain patterns existed between these situations. These findings led to another study where we further analyzed these situations and found out what factors caused most players to show a rise in interest levels. We were able to divide these factors into 6 different categories called Triggers: "Anticipation", "Concentration", "Surprise", "Frustration", "Overwhelm" and "Fear". As these triggers represent mutually exclusive elements that affect a player's interest levels, we found that in most situations where many test subjects showed a rise in interest levels, more than one trigger is present, a phenomenon we call Stacking. While our study is still ongoing, we believe that by using these triggers as guidelines, game designers will be able to intentionally plan and control the player's interest level for FPS games with a certain level of guarantee"

Patterns as Objectives for Level Generation - 0 views

  •  
    Abstract: "This paper discusses how to use design patterns in procedural level generation, with particular reference to the classic console game Super Mario Bros. In a previous paper, we analyzed the levels in this game to nd a set of recurring level design patterns, and discussed an implementation where levels were produced from concatenation of these patterns. In this paper, we instead propose using patterns as design objectives. An implementation of this based on evolutionary computation is presented. In this implementation, levels are represented as a set of vertical slices from the original game, and the tness function count the number of patterns found. Qualitative analysis of generated levels is performed in order to identify strengths and challenges of this method"

A procedural procedural level generator generator - 0 views

  •  
    Abstract: "Procedural content generation (PCG) is concerned with automatically generating game content, such as levels, rules, textures and items. But could the content generator itself be seen as content, and thus generated automatically? This would be very useful if one wanted to avoid writing a content generator for a new game, or if one wanted to create a content generator that generates an arbitrary amount of content with a particular style or theme. In this paper, we present a procedural procedural level generator generator for Super Mario Bros. It is an interactive evolutionary algorithm that evolves agentbased level generators. The human user makes the aesthetic judgment on what generators to prefer, based on several views of the generated levels including a possibility to play them, and a simulation-based estimate of the playability of the levels. We investigate the characteristics of the generated levels, and to what extent there is similarity or dissimilarity between levels and between generators."

"Game Challenge: A Factorial Analysis Approach" by Ian J. Fraser - 0 views

  •  
    Abstract: "Video games that customize to a player's experience level and abilities have the potential to allow a broader range of players to become engaged and maintain interest as they progress in experience level. A game that uniquely customizes the player's experience could attract additional demographics to gaming, which will result in a distinct edge in marketability and potential revenue. This thesis examines a subsection of adaptive gaming systems from the perspective of identifying game factors that alter the level of difficulty. Our focus is to provide a solution useful to both research and commercial gaming communities by developing a system that simulates results offline yet can be integrated into online play. While online performance is the main goal of an adaptive system, the offline simulation provides several benefits. Offline simulation allows the elimination of insignificant factors from inclusion in the training and evolution phase of machine learning algorithms. In addition it provides commercial games with a useful tool or method for performing game balancing and level tuning. To test our approach we designed a test-bed version of the game Pac-Man. The experimental testbed alters environment variables to evaluate their effect on a set of selected response variables. Observing the results of several response variables provides the potential to represent multiple player states, though our focus is on controlling the difficulty for a player. The testbed will simulate the actions of both Pac-Man and the ghosts over a variety of different settings and strategies. The evaluation of a factor's significance and its effect size are calculated using a factorial analysis approach. This method allows the identification of factors relevant to both individual strategies, and the set of all player strategies. Finally, as a proof of concept for both the online and adaptation prospects of this method, we developed a prototype adaptive system. Utilizing the releva

RRT-Based Game Level Analysis, Visualization, and Visual Refinement - 0 views

  •  
    From the abstract: "In this paper we tackle automating level design. We describe a general graph-based representation for game levels and present a preliminary system that leverages this representation. Our system automatically explores existing levels of a 2D platform game using the rapidlyexploring random tree (RRT) algorithm and constructs a compact graph representation from this exploration. Our system can also modify a graph representation onthe- fly to reflect user-directed changes to the existing level structure. This work constitutes an initial step toward the larger goal of automating level design in a general way."

EXPRESSIVE DESIGN TOOLS: PROCEDURAL CONTENT GENERATION FOR GAME DESIGNERS - 1 views

  •  
    "This dissertation presents the use of procedural content generation to create expressive design tools: content generators that are accessible to designers, supporting the creation of new kinds of design tools and enabling the exploration of a new genre of game involving the deep integration of procedural content generation into game mechanics and aesthetics. The first of these tools is Tanagra, the first ever AI-assisted level design tool that supports a designer creating levels for 2D platforming games. Tanagra guarantees that levels created in the tool are playable, and provides the designer with the ability to modify generated levels and directly control level pacing. The second tool is Launchpad, which supports a designer controlling both component and pacing features of generated levels; its companion game Endless Web uses the generator to create an infinite world for players to explore and alter through their choices. Endless Web is one of a handful of games in a new genre enabled by content generation: PCG-based games. Finally, this dissertation presents a novel method for understanding, visualizing, and comparing a generator's expressive range, thus allowing designers to understand the implications of decisions they will make during the design process."

Mechanic Miner: Re ection-Driven Game Mechanic Discovery and Level Design - 0 views

  •  
    Abstract: "We introduce Mechanic Miner, an evolutionary system for discovering simple two-state game mechanics for puzzle platform games. We demonstrate how a re ection-driven generation technique can use a simulation of gameplay to select good mechanics, and how the simulation- driven process can be inverted to produce challenging levels speci c to a generated mechanic. We give examples of levels and mechanics generated by the system, summarise a small pilot study conducted with example levels and mechanics, and point to further applications of the technique, including applications to automated game design."

Read, Write, Play: An Educational Mobile Gaming Platform - 0 views

  •  
    Abstract: "We introduce ALE, a new framework for writing games for the An- droid platform. The primary motivation behind ALE is to empha- size reading code before writing it. Beginners read game code to learn how levels can be made, and advanced users read the code of ALE itself to learn how to create useful and extensible libraries. To date, roughly 200 students at our university have used ALE, rang- ing from first-semester engineering undergraduates through Mas- ters students. ALE has proven useful in teaching non-majors about CS, in making introductory CS programming courses more excit- ing, and in encouraging creativity, entrepreneurship, and good pro- gram design in upper-level electives. Based on these experiences, we encourage educators at all levels to consider using ALE to im- prove students' ability to learn by reading code."

Mobile adaptive procedural content generation - 0 views

  •  
    From the abstract: "In this paper, we propose the integration of two PCG-based approaches (experiencedriven and context-driven PCG) to support the generation of adaptive mobile game levels. We present and discuss the implementation of our approach in an existing game, 7's Wild Ride. Gameplay semantics and player modeling are used to steer a level generator, featuring a time-dependent dynamic diculty adjustment mechanism. From our two user studies, we conclude that (i) context-driven levels are preferable over traditional ones, and (ii) the game can adapt to di erent player types, keeping its gameplay balanced and player satisfaction."

ScriptEase II and Platform Independent Story Creation Using High-Level Game Design Patt... - 0 views

  •  
    Abstract: "As the video game industry grows, both developers and cre- ative authors are seeking new ways to convert story content into scripting code, which is often a difficult process dur- ing game creation. ScriptEase II provides a solution to this common bottleneck in the games design process. Although the goals are similar to the goals of ScriptEase, ScriptEase II is able to generate code for any game engine with a provided translator. It utilizes high-level game design patterns such as cause-effect and quest patterns which can be abstracted between most games. In addition, ScriptEase II further en- hances the use of these patterns with a simple drag-and-drop interface. The generality of the code generation has been tested using two different game engines, and it can be used to further test the benefits of using high-level game design patterns in content creation."

Model-Driven Development of Game AI: Research Plan - 0 views

  •  
    "As research for a Ph.D. thesis, we propose to show that a layered Statechart-based AI is a suitable formalism for Game AI, enabling the use of model-driven development techniques such as reuse and high-level analysis including model-checking. The fundamentally modular nature of this approach leads naturally to reuse as a fundamental component of the design process. Supported by a clearly defined formalism, useful behavioural analyses become possible, such as testing reactions to various inputs at design time. We also explore transformations at the modelling level to enable procedural generation, allowing rapid deployment of varying AIs. Additionally, such a model allows for the generation of efficient code that can be directly inserted into games. Tool support for reuse, generation, and analysis will be developed, then employed in creating an industrial scale AI, proving that this formalism is appropriate for industrial use."

Visual Communicators Made Through Play: A Game for Learning in Graphic Design - 0 views

  •  
    Abstract: "This paper explores the possibilities of game-based learning within the context of a graphic design education. A global network now exists that puts all professionals in competition with one-another, and in order to stay competitive as educators, we must be able to produce professionals that can solve problems creatively. However, traditional teaching methods may in some contexts be unable to provide the kind of education students need, and initial research suggests that game-based learning may be a viable solution. This study establishes a framework of good game-based learning principles and a design for a video game to be used in a teaching environment. Primarily target audiences are teenage students, roughly ages 10 - 14, and college level undergraduate students, ages 18 - 25, of all genders. This video game is intended to teach players situated meanings for key visual communication concepts of grid and modularity, in a way that allows them to create high level relationships between these and their creative work."

Digging deeper into platform game level design: session size and sequential features - 0 views

  •  
    Abstract: "A recent trend within computational intelligence and games research is to investigate how to affect video game players' in-game experience by designing and/or modifying aspects of game content. Analysing the relationship between game content, player behaviour and self-reported affective states constitutes an important step towards understanding game experience and constructing effective game adaptation mechanisms. This papers reports on further refinement of a method to understand this relationship by analysing data collected from players, building models that predict player experience and analysing what features of game and player data predict player affect best. We analyse data from players playing 780 pairs of short game sessions of the platform game Super Mario Bros, investigate the impact of the session size and what part of the level that has the major affect on player experience. Several types of features are explored, including item frequencies and patterns extracted through frequent sequence mining."

A Platformer Game in Flash Self Defined Project - 0 views

  •  
    "This project involves developing an action-platformer game for the Flash platform. The user controls a character who must progress through levels, while avoiding obstacles, collecting items and fighting many types of enemies. Role-playing game elements such as equipment and upgrades support user customization and varied battle strategies. Developing a successful Flash game involves several factors. Flash games must be simple to get into, yet rewarding to play in both short and long sessions. Flash games must be accessible to a wide audience; both in terms of user preferences and technical limitations. Finally, Flash games must offer something unique to stand out from the crowd, in a market where hundreds of free games are published every month. This report covers the research, design and implementation done to achieve these requirements, in terms of game mechanics, interface, level design, visual design, accessibility options, and replay value. Technical challenges include building, testing and optimizing a game engine and interface from scratch, balancing the game mechanics and difficulty, and structuring the whole development process in a way that enables easy creation of new content. In addition to game design and development, this project also deals with the business aspects of developing online games; how games generate revenue, how they are marketed and distributed, and developing trends in the consumer market. Project success in different areas has been evaluated through usability studies, user ratings and reviews, and vast quantities of usage and distribution statistics. Overall, the project has been a success in terms of user reception and generated revenue, and the final section of this report includes plans for a second game, utilizing and building upon the same game engine and mechanics."
