Primary Areas of Interest


Metagame Analysis in League of Legends

Metagames are the perceived optimal or dominant playing strategy. They are set of popular strategies or overarching way of play that appears optimised for an individual player or team based on both their perceived strengths and weaknesses as well as those of their respective opponents, using information contained both in and outside the game and its surrounding environment. They are never created in isolation, and rather they are part of a shifting ecosystem of highly public competitive play.

Cognitive Function of Esports player

Cognitive function of gamers refer to the collective cognitive characteristics of gamers who plan and execute appropriate input actions in response to input tasks to be performed in games. 
Esports players show shorter reaction time, higher accuracy and precision than general gamers, but there is no quantitative study on Esports player. Based on the modeling and testing tools in the cognitive function research in existing sports, we develops a cognitive function measurement program by evaluating and analyzing the objective cognitive ability of various Esports players.

Aging curve of Esports player

The performance of athletes is significantly affected by age. The performance of athletes grow and decline with age, and the expression of this degree as a function is called the aging curve. We predict and evaluate the age-related changes of players based on modeling the position and initial performance of Esports players.

The game of Go after Alphago

One of the most surprising events in AI over the past decade is the advent of AlphaGo developed by Alphabet's Google DeepMind. We study the impact of AI on Go players with the changes in play style and the changes in age-specific performance.

CHI 2022 Papers - How AI-Based Training Affected Performance of Professional Go Players

Since the advent of AlphaGo, Artificial Intelligence(AI) has been actively introduced into the Go training. We analyzed how the performance of professional Go players has changed since the advent of AlphaGo, and the significant impact of AI-based training was confirmed. We interviewed and surveyed professional Go players and found that AI has been actively introduced into the Go training process since the advent of AlphaGo. The significant impact of AI-based training was confirmed in a subsequent analysis of 6,292 games in Korean Go tournaments and Elo rating data of 1,362 Go players worldwide. Overall, the tendency of players to make moves similar to those recommended by AI has sharply increased since 2017. The degree to which players’ expected win rates fluctuate during a game has also decreased significantly since 2017. We also found that AI-based training has provided more benefits to senior players and allowed them to achieve Elo ratings higher than those of junior players.

eSports & Games Studies - Aging curve of eSports players in League of Legends, 2021

In this paper, the effect of the eSports player's age on the performance in four major regional leagues of League of Legends (LCK, LPL, LEC, and LCS) was investigated from spring 2016 to summer 2020.
