• Bridging the Gap Between Medical and Gaming BCI G-Tec's expertise in medical BCI applications provides them with a unique advantage in the gaming space. They are working on adapting their existing technology and expertise to create BCI solutions tailored for gaming. This approach leverages their knowledge of brain signal processing and user experience design to create BCI gaming experiences that are both engaging and reliable.

While the potential of BCI in gaming is vast, several challenges need to be addressed:

• Data Acquisition and Interpretation Collecting and interpreting brain signals accurately and efficiently is crucial for BCI gaming. G.TEC recognizes the primary challenge of data availability, as acquiring high-quality brain data is an expensive and sensitive process. As one researcher explained, "Collecting data for BCI is really expensive and usually when done by companies or institutions, they're not really willing to share the data, these data are sensitive."
• Hardware and Ergonomics Current BCI systems often involve bulky and uncomfortable equipment. G.TEC is working on designing more ergonomic and user-friendly BCI devices that are suitable for extended gaming sessions. This includes exploring new form factors, such as headbands or even integrated into virtual reality, or VR, headsets, to ensure comfort and seamless gameplay. Overcoming the ergonomic challenges of creating BCI devices that can be comfortably worn for prolonged periods without causing discomfort is a critical factor in enabling widespread adoption of BCI technology in daily life.

As one representative acknowledged, "So creating devices who are actually good in the ergonomics that can be used in a daily life or more than 30 minutes without feeling annoyance. So that's probably the second one."

• Standardization and Interoperability The lack of standardized protocols and data formats in the BCI field can hinder collaboration and innovation. G.TEC recognizes the importance of establishing common standards to ensure interoperability between different BCI devices and software platforms. This will allow for wider adoption and encourage collaboration among developers and researchers. Currently, the lack of industry standardization results in a fragmented market, with each company following its own proprietary methods for hardware and software development, limiting cross-compatibility across devices and applications.

"And the third one is the lack of a standard. There is no at the moment standardization in the industry. So every company working in this industry is doing things their own way, in-house, probably both hardware and software," a researcher explained.

• Ethical Considerations Data privacy, security and potential brain manipulation are serious ethical concerns surrounding BCI technology. G.TEC is committed to developing BCI solutions with robust security measures and ethical data handling practices. This includes obtaining informed consent from users, ensuring data anonymization and implementing safeguards against the potential misuse of brain data.

G.TEC recognizes the sensitivity of handling personalized brain data and the need for strict regulations to protect individual privacy. As one representative cautioned, "When you decode the brain signal, you can actually know a person more. And with technology improving, who knows what information is hidden underneath it."

Addressing these challenges requires a collaborative effort from researchers, developers, ethicists and policymakers. G.TEC's presence at GDC signifies their commitment to working with the gaming industry to find solutions and ensure the responsible development and implementation of BCI technology in gaming.

One of the profound applications of BCI technology is its potential to empower individuals with disabilities. As technology advances, providing multiple avenues for accessing and interacting with devices becomes increasingly important. BCI systems can be combined with eye-tracking, tongue control and electromyography, or EMG, to offer alternative means of control for those with physical limitations.

As one representative noted, "So I would say from my experience and also what I've seen in the literature and research that it's becoming important for these people to have multiple ways to use technology."

EEG-based BCI solutions stand out as affordable and user-friendly options for individuals who face barriers in accessing technology. For instance, stroke rehabilitation systems can directly aid in improving motor function, while research is underway to explore the integration of BCI with VR for enhancing attention and cognitive abilities in children with attention deficit hyperactivity disorder, or ADHD.
