If you're looking for something other than Neuralink, EMOTIV is another interesting option. The company offers EEG hardware and software products, including high-density saline and gel EEG head cap systems and AI-based software for capturing, processing and experimenting with brain data. That could be useful for personal development and scientific research, with easy-to-use, Bluetooth-connected devices that work on multiple operating systems.
Another alternative is Be My Eyes, which uses live video and AI to improve accessibility. The service connects blind and low-vision people with sighted volunteers and businesses, offering live video support, AI-generated photo descriptions and an accessible customer service suite. The idea is to improve the customer experience and resolve issues more quickly for businesses.
These alternatives, while not as ambitious as Neuralink's plans, offer interesting ideas in the areas of accessibility and brain-computer interface, so they're worth considering for your needs.
