In a groundbreaking move, Apple Inc. has announced its foray into brain-computer interfaces (BCIs), unveiling a technology that could redefine how humans interact with devices. The company is developing a system to allow users to control iPhones, iPads, and Vision Pro headsets using neural signals captured by brain implants. This innovation promises to enhance accessibility for individuals with severe mobility impairments, such as those with spinal cord injuries or amyotrophic lateral sclerosis (ALS), while laying the groundwork for broader applications in the future.
Apple’s initiative centers on a new standard developed in collaboration with Synchron, a company that produces a stent-like implant called the Stentrode. Unlike traditional implants, the Stentrode is inserted into a vein atop the brain’s motor cortex, where its 16 electrodes detect neural signals. These signals are translated into actions, such as selecting icons on a screen, through Apple’s switch control feature, which integrates alternative input devices into its operating systems. The technology builds on Apple’s prior work, such as its 2014 Bluetooth standard for hearing aids, which became widely adopted.
Mark Jackson, an ALS patient and early tester of the Stentrode, exemplifies the technology’s potential. Unable to travel due to his condition, Jackson used the implant alongside an Apple virtual-reality headset to virtually experience standing on a Swiss Alps mountain ledge. From his home near Pittsburgh, he is learning to navigate his iPhone and other Apple devices by thought alone. However, Jackson noted that the technology is still in its infancy, with navigation slower than traditional inputs like touchscreens or mice.
Competitors like Neuralink, founded by Elon Musk, are also advancing BCI technology. Neuralink’s N1 implant, with over 1,000 electrodes embedded directly in the brain, captures more detailed neural data than the Stentrode. Its first user demonstrated the ability to move a cursor faster than some mouse users, converting brain signals into clicks or keystrokes. Musk envisions BCIs enhancing human cognition to keep pace with artificial intelligence.
Morgan Stanley estimates that 150,000 Americans with severe upper-limb impairments could benefit from BCIs initially. Apple’s early adoption of this technology positions it as a pioneer in accessibility and human-computer interaction. While full FDA approval for widespread use remains years away, Apple’s collaboration with Synchron signals a future where thought-controlled devices could become as intuitive as today’s touchscreens.
The potential benefits of BCIs are vast, from empowering those with disabilities to revolutionizing gaming, communication, and productivity. However, challenges like improving speed, ensuring safety, and addressing ethical concerns remain. As Apple pushes forward, its BCI standard could set a benchmark for the industry, much like its past innovations in smartphones and wearables.
