Understanding and Proposing a Design Rationale of Digital Games based on Brain-Computer Interface: Results of the AdmiralMind Battleship Study

Abstract

Brain-Computer Interfaces (BCIs) present great potential to the field of digital games, though the design of this kind of interface is still a challenge for most of the game designers and developers. In this work it is presented a literature review about digital games based on BCI, aiming to analyze the interaction design of these games, to identify the approaches applied, limitations and implications related to BCIs design. After the review, we accomplish a reflection about the design decisions involved in the development of digital games based on BCI. This approach leads to the construction of a design rationale developed to support the process of BCI-based games, with its use established on the design of a battleship game based on BCI. As contributions of this work, we highlight the literature review, design rationale and results of the study accomplished.

The PGIRec Software to Support the Evaluation of User-System Interaction with a Synchronous and Multi-perspective Recording System

“…War, in which online players are organized into teams to participate in virtual tug-of-war competitions. The pulling force in the tug-of-war game is computed by the player's level of concentration, acquired through a brain-computer interface (Ferreira et al, 2014;Vasiljevic and Miranda, 2020a). In this game, players can act collaboratively, when playing on the same team, or competitively, when on opposite teams.…”

“…The domain of digital games stands out among other interactive software in its scope of platforms, usage context, and simultaneous users, as the same game can be played on different platforms, presented in different ways, and multiple players can interact simultaneously in the same virtual environment through different interfaces. In addition to qualitative or objective investigations on player interaction, which can be performed using physical controls (e.g., keyboard, mouse and joystick), or even physiological ones (using biosignal sensors) (Ferreira et al, 2014;Vasiljevic and Miranda, 2020b), researches that also investigate the interaction between players can also be relevant in the context of games, especially in multiplayer games, both in cooperative, collaborative and competitive modes.…”

Player-Game Interaction Recorder: A recording software to support the evaluation of players interaction with digital games

“…• Jogo utilizado no estudo e seu gameplay: Um jogo multiplayer onde os jogadores online são organizados em times, a fim de participar de competições virtuais de cabo de guerra. A força para puxar o cabo de guerra é computada pelo nível de concentração do jogador, capturado através de uma interface cérebrocomputador [Ferreira et al 2014]. Neste jogo, os jogadores podem atuar de forma colaborativa (quando estão jogando no mesmo time) ou de modo competitivo (quando estão em times opostos).…”
