“…This opinion is rather qualified in the scientific community, which reported that BCIs suffer from (1) a low transfer rate, (2) a lack of market-ready, affordable, and user-friendly research-grade EEG acquisition devices, and (3) a gap between the game design and graphics of video games available on the market vs. in laboratories. Priorities of these limitations for video game development are discussed in the literature (Nijholt et al, 2009;Ferreira et al, 2013;Marshall et al, 2013;van de Laar et al, 2013;Ahn et al, 2014;Cattan et al, 2018b;Kerous et al, 2018;Vasiljevic and Miranda, 2019;Pierce et al, 2020), and in general preponderance of quantitative over qualitative aspects is criticized (Nijholt et al, 2009;Vasiljevic and Miranda, 2019). This article supports the claim that BCIs are not ready for general public use, based on other aspects than performance.…”
