I had an OCZ Nia Neural impulse actuator back in 2008/2009. It was extremely difficult to setup and get it trained. Frustratingly slow because for long periods of times it felt like nothing was happening. It was also a complex process setting it up for use with each game. OCZ had profiles for some games which saved a bit of time. However, after a couple of months it started to click and I could use it pretty well. It worked really good in games that OCZ did profiles for. Half Life 2 and Counter Strike Source. Could walk around a map duck, dodge, shoot, the whole works.
Outside of the very complex and frustrating setup process, the main problem with it was that it was extremely difficult to control your reactions, facial movements etc. You couldn't talk to teammates in Counter Strike, for example, or else it would do something unexpected in the game. No eating or drinking while gaming either. You had to be completely zen in both mind and facial expressions to use it properly.
I am mentioning this because I am surprised it took this long to get from the likes of the OCZ device to the Neuralink mentioned in the opening post. The addition of an implant must be what it gives it the fine control so that you don't have to be so completely focused on the one thing.
With implants like this, I am guessing sight and hearing loss will soon be things of the past for those that can afford it? Will implants like this solve things like Dementia and Alzheimer's?
Interesting times.
