The Apple Vision Pro offers remarkable ease of use, largely due to its controller-free interface. Users simply gaze at a control and tap their index finger to their thumb to make selections. However, hand gestures can be challenging, if not impossible, for millions of individuals worldwide suffering from upper limb paralysis. Recently, Synchron unveiled a significant advancement in spatial computing, enabling users of the Stentrode brain-computer interface (BCI) implant to control the Apple Vision Pro.
A demonstration video showcased Mark, a user with amyotrophic lateral sclerosis (ALS) who has lost the ability to move his hands. Thanks to the BCI, he can now engage with a mixed-reality headset. The Vision Pro’s eye-tracking technology allows the cursor to move with just a look, and Synchron’s BCI detects Mark's intent to perform small hand gestures. He was able to play Solitaire, browse the internet, watch videos on Apple TV, and send text messages, selecting words through a combination of Synchron’s BCI and Vision Pro software.
This breakthrough follows a notable demonstration where Mark utilized a text chat interface enhanced by ChatGPT, which streamlines communication. Synchron's YouTube video highlights this innovative technology. Long before Neuralink, Synchron was at the forefront of BCI research, with the Stentrode being the first BCI to be implanted in humans, starting its clinical trials in 2022. Synchron employs well-established methods such as stents and endovascular surgery. While Neuralink offers impressive capabilities that mimic mouse control through its BCI, it requires invasive skull surgery.
Although BCI hardware tends to dominate headlines, effective software integration with external devices is crucial for creating a seamless and user-friendly experience—something this new technology exemplifies. Currently, the availability of this innovation is limited due to ongoing clinical trials for both Synchron and Neuralink. As a result, it may take several years before widespread thought control of computers becomes a reality. While advancements like these are thrilling, extensive testing over time is essential to ensure user safety.
