This work includes a push with Microsoft for the November launch of its Halo 4 game. As part of a greater demonstration at Yonge-Dundas Square, the brand and Interaxon set up shop with a game that needed to be controlled with the player’s mind. The challenge was to keep a ball of light contained – requiring lots of concentration.
The dramatic increase in publications after 2007 (Figure 2) seems to have been caused by the release of wireless EEG devices. Because of their ease of use and low cost, we believe that as the market in EEG devices matures, more researchers will choose EEG as measurement method. Table 1 shows the EEG devices currently on the market or in preparation for marketing. Briefly, nine devices are notable, most of which support wireless communication with reasonable sampling rates from 128 Hz to 1 kHz. Considering that most BCI research extracts features below 100 Hz [17], the sampling rate is sufficient to implement BCI. Except for “Emotiv EPOC”, none of these devices supports electrodes covering the central area; instead, most of them measure brain waves on the forehead. In our web search, we found three products—“Melon EEG headband”, “InteraXon Muse” and “Emotiv Insight”—that are gaining public attention by reaching their target figure through the funding platform “Kickstarter” (www.kickstarter.com). Looking at the success of this fundraising effort, “Emotiv Insight”, for example, achieved over 1600% of its goal; this fact demonstrates the strong interest of the public in BCI and BCI hardware.
The UK's Science Media Centre, which does a good job of trying to make complex scientific stories accessible, put out a press release quoting Prof Andrew Jackson, professor of neural interfaces at Newcastle University.
"I don't think there was anything revolutionary in the presentation," he said.
"But they are working through the engineering challenges of placing multiple electrodes into the brain.
"In terms of their technology, 1,024 channels is not that impressive these days, but the electronics to relay them wirelessly is state-of-the-art, and the robotic implantation is nice.
"The biggest challenge is what you do with all this brain data. The demonstrations were actually quite underwhelming in this regard, and didn't show anything that hasn't been done before."
He went on to question why Neuralink's work was not being published in peer-reviewed papers.
