Building mixed-initiative (AI-assisted) tools that collaborate with designers to create interactive narrative scenarios.
Creating a mixed-initiative AI system to evolve new behavior from human-designed behavior trees in Unreal Engine 4.
We present an analysis of the academic landscape of games research from the last 15 years. We employed a data driven approach utilizing co-word and co-venue analysis on 48 core venues to identify 20 major research themes and 7 distinct communities, with a total of 8,207 articles and 21,552 unique keywords being analyzed. The results validated the commonly held assumption that games research has different clusters of papers and venues for technical versus nontechnical research, and identified interactions and synergies between these research clusters.
Using an Role-Playing Game (RPG) with multiple affordances, we designed an experiment collecting granular in-game behaviors of players. Using sequential pattern mining and supervised learning, we developed a model that uses gameplay action sequences to predict the real world characteristics, including gender, game play expertise and five personality traits (as defined by psychology). The results show that game expertise is a dominant factor that impacts in-game behaviors.
In this paper, we consider the problem of skill decomposition in MOBA (MultiPlayer Online Battle Arena) games, with the goal to understand what player skill factors are essential for the outcome of a game match. To understand the construct of MOBA player skills, we utilize various skill-based predictive models to decompose player skills into interpretative parts, the impact of which are assessed in statistical terms. We apply this analysis approach on two widely known MOBAs, namely League of Legends (LoL) and Defense of the Ancients 2 (DOTA2). The finding is that base skills of in-game avatars, base skills of players, and players’ champion-specific skills are three prominent skill components influencing LoL’s match outcomes, while those of DOTA2 are mainly impacted by in-game avatars’ base skills but not much by the other two.
Deck building is a crucial component in playing Collectible Card Games (CCGs). The goal of deck building is to choose a fixed-sized subset of cards from a large card pool, so that they work well together in-game against specific opponents. We propose a deck recommendation system, named Q-DeckRec, which requires small computational resources to recommend winning-effective decks after a training phase thus is suitable for real-time or large-scale application.
Matchmaking connects multiple players to participate in online player-versus-player games. Current matchmaking systems depend on a single core strategy: create fair games at all times. These systems pair similarly skilled players on the assumption that a fair game is best player experience. We demonstrate, however, that this intuitive assumption sometimes fails and that matchmaking based on fairness is not optimal for engagement. Therefore, we propose an Engagement Optimized Matchmaking (EOMM) framework that maximizes overall player engagement. We prove that equal-skill based matchmaking is a special case of EOMM on a highly simplified assumption that rarely holds in reality. Our simulation on real data from a popular game made by Electronic Arts,Inc. (EA) supports our theoretical results, showing significant improvement in enhancing player engagement compared to existing matchmaking methods.
Hero drafting is a challenging problem in MOBA (MultiPlayer Online Battle Arena) games due to the complex hero-to-hero relationships to consider. We propose a novel hero recommendation system that suggests heroes to add to an existing team while maximizing the team’s prospect for victory. To that end, we model the drafting between two teams as a combinatorial game and use Monte Carlo Tree Search (MCTS) for estimating the values of hero combinations. Our empirical evaluation shows that hero teams drafted by our recommendation algorithm have significantly a higher win rate against teams constructed by other baseline and state-of-the-art strategies.
Foldit is a revolutionary crowdsourcing computer game enabling you to contribute to important scientific research by folding proteins in a 3D puzzle game.
Building a system to visualize and identify player as well as team behaviors and strategies.
This project aims to the use a custom-built Alternate Reality Game (ARG) to assess the influence of individual differences on adaptability and teamwork in a digital gaming settings. It has three aims: To develop ARG-based quantitative computational measures that can assess adaptability and performance based on game data, to develop self-report measures that can characterize and measure adaptation processes and behaviours in a mixed-method way, and to validate all behaviour and adaptation measures resulting from this study in the real world.
Description: The project explores the design and development of a 3D puzzle-based game, called May’s Journey, in which players solve an environmental maze by using the game’s pseudo code to manipulate game objects. The game is designed to teach introductory but foundational concepts of computer programming including abstraction, modularity, reusability, and debugging by focusing players […]

Short Bio: Magy Seif El-Nasr is an Associate Professor in the Colleges of Computer and Information Sciences and Arts, Media and Design at Northeastern University. Professor Seif El-Nasr directs the PLAIT (Playable Innovative Technologies) Lab. Prior to joining Northeastern, she was an assistant professor at the School of Interactive Arts and Technology at Simon Fraser University (2007-2011). Before that she was an assistant professor at the School of Information Science and Technology at Pennsylvania State University (2003-2007).
Professor Seif El-Nasr believes that problems we currently face in the areas of health, education, resilience, and cybersecurity require an interdisciplinary approach and most often require us to understand human behavior, learning, and human cognition at a deep level which we currently do not possess. Her research focuses on building a framework to facilitate the use of virtual environments (e.g., games, VR, apps, social media or interactive narrative) as a methodology to understand human behavior and cognition, with the goal of facilitating computational solutions to national problems in health, education and security. To address this vision, she develops tools and automated techniques to help author virtual environments (e.g., interactive narratives, believable characters, etc.), as well as data driven analytics to model human behavior in such environments, which can be used to assess as well as personalize the environments towards effective use in solving national problems, such as health and learning.
Professor Seif El-Nasr has chaired and co-chaired several conferences, including PETRA 2013, AIIDE 2013, Foundations of Digital Games (FDG) 2012, International Conference on Entertainment Computing (ICEC) 2011 (Co-Chair), Advances in Computer Entertainment (ACE) 2009 (Program Co-Chair), Computer Human Interaction 2015 (Associate Chair). She also serves on the editorial board of the IEEE Transactions on Computational Intelligence and Game Artificial Intelligence, IEEE Transactions on Affective Computing, Entertainment Computing Journal, and ACM’s Computers in Entertainment. She has also served on several NSF panels throughout her career, and has severed on numerous SIGs, including ACM Representative for TC14 IFIP on Entertainment Computing. In 2017, Dr. Self El-Nasr was selected among 30 game scholars named as fellows for the Higher Education Video Game Association, an association that aims to cultivate a community on game scholarship and education around the world. This was to recognize her leadership role in pioneering and developing games as a field of scholarship and education.
