The tech world is abuzz with activity as major companies file patents pushing the boundaries of what was once considered science fiction: mind-reading and dream control. While the full implications of these technologies are still years away, the filings offer a glimpse into the future that tech giants are actively trying to build.
Decoding Brain Activity
Meta, formerly Facebook, is heavily invested in technology that can decode brain activity. The company is developing non-invasive brain-computer interfaces that interpret neural signals, allowing for hands-free control of digital devices. The aim isn't to extract your innermost thoughts, but rather to understand brain activity linked to specific actions and intentions. Meta's patents include tools that read neural and muscular signals for use in controlling the metaverse. One patent details an in-ear electroencephalography (EEG) system that uses an electrode in the ear canal to generate neural signal data. This system can detect not only brain activity but also activity from other parts of the body, such as the eyes and heart. Additionally, Meta seeks to patent a system for "neuromuscular-signal-based detection" of in-air hand gestures, enabling users to produce and modify text in extended reality environments.
Apple has also shown interest in similar technology, filing a patent for AirPods that use EEG technology to measure biosignals and electrical activity in the brain.
Dream Monitoring and Manipulation
Samsung has patented wearable technology designed to monitor brain activity during sleep and subtly influence the content of dreams. The device aims to detect when a user is dreaming and then introduce cues, such as audio, visual, scent, or vibration, to steer the dream in a particular direction. The device could be worn as a headband, smartwatch, or smart glasses. The technology could interpret the emotional tone of a dream; for example, specific brainwave patterns combined with a spike in heart rate might indicate a nightmare. The device isn't reading thoughts or seeing dream images but rather reading physiological correlates of emotional experience. By providing gentle guidance and support, it could make the dream world safer, more inspiring, and more meaningful.
Ethical Considerations and Concerns
The rapid advancement of neurotechnology raises ethical concerns. Experts and activists are advocating for legislation to safeguard mental privacy as tech companies continue to fund brain-scanning research. One of the primary concerns is the potential misuse or abuse of neurotechnology. The Neurorights Foundation evaluated the privacy practices of 30 major consumer neurotech companies and found that all of them take possession of all user data. There are also concerns about emotion manipulation. AI can detect a user's mood and influence their decisions through targeted content.
The Future of Neurotechnology
Despite the ethical concerns, the potential applications of neurotechnology are vast. Non-invasive mind-reading technology could revolutionize medicine, particularly for patients who have lost the ability to speak or move. Dream control technology could be used to treat nightmares, boost creativity, and enable therapeutic or learning applications. As the technology becomes less invasive and more accessible, it could transform how we interact with computers and the world around us. Microsoft is also exploring futuristic concepts, such as a teleportation system that uses holographic projections to allow users to virtually transport themselves anywhere in the world. Amazon has patented emotion-reading Alexa technology that detects a user's mood from their voice to personalize responses.
These patents signal a significant shift in how technology interacts with the human mind. As big tech companies continue to invest in neurotechnology, it is crucial to address the ethical implications and ensure that these powerful tools are used responsibly. The line between science fiction and reality is blurring, and the next decade promises to bring even more astounding advancements in this field.
