The Future is Here: First Brain-to-Brain Interface! a first amongst firsts, a team of international researchers have reported that they have built the first human-to-human brain-to-brain interface; allowing two humans — separated by the internet — to consciously communicate with each other. One researcher, attached to a brain-computer interface (BCI) in India, successfully sent words into the brain of another researcher in France, who was wearing a computer-to-brain interface (CBI).

In short, the researchers have created a device that allows people to communicate telepathically. And it’s no surprise, given the immense amount of progress being made in the field. Over the last few years, brain-computer interfaces that you can plug into your computer’s USB port have been commercially available. And in the last couple of years we’ve seen advanced BCIs that can be implanted directly into your brain.

BCICreating a brain-to-brain connection is a bit more difficult though, as it requires that brain activity not only be read, but inputted into someone else’s brain. Now, however, a team of international researchers have cracked it. On the BCI side of things, the researchers used a fairly standard EEG (electroencephalogram) from Neuroelectrics. For the CBI, which requires a more involved setup, a transcranial magnetic stimulation (TMS) rig was used.

To break the process down, the BCI reads the sender’s thoughts, like to move their hands or feet, which are then broken down into binary 1s and 0s. These encoded thoughts are then transmitted via the internet (or some other network) to the recipient, who is wearing a TMS. The TMS is focused on the recipient’s visual cortex, and it receives a “1″ from the sender, it stimulates a region in the visual cortex that produces a phosphene. is a phenomenon whereby a person sees flashes of light, without light actually hitting the retina. The recipient “sees” these phosphenes at the bottom of their visual field, and by decoding the flashes — phosphene flash = 1, no phosphene = 0 — the recipient can “read” the word being sent. While this is certainly a rather complex way of sending messages from one brain to another, for now, it is truly state of the art.

TMS is somewhat similar to TDCS (transcranial direct-current stimulation), in that it can stimulate regions of neurons in your brain. But instead of electrical current, it uses magnetism, and is a completely non-invasive way of stimulating certain sections of the brain and allowing a person to think and feel a certain way. In short, there doesn’t need to be any surgery or electrodes implanted into the user’s brain to make it happen.

brain-to-brain-interfacingThis method also neatly sidestep the fact that we really don’t know how the human brain encodes information. And so, for now, instead of importing a “native” message, we have to use our own encoding scheme (binary) and a quirk of the visual cortex. And even if it does seem a little bit like hard work, there’s no denying that this is a conscious, non-invasive brain-to-brain connection.

With some refinement, it’s not hard to imagine a small, lightweight EEG that allows the sender to constantly stream thoughts back to the receiver. In the future, rather than vocalizing speech, or vainly attempting to vocalize one’s own emotions, people could very well communicate their thoughts and feelings via a neural link that is accommodated by simple headbands with embedded sensors.

Brain-ScanAnd imagine a world where instant messaging and video conferencing have the added feature of direct thought sharing. Or an The Internet of Thoughts, where people can transfer terabytes worth of brain activity the same way they share video, messages and documents. Remember, the internet began as a small-scale connection between a few universities, labs and research projects.

I can foresee a similar network being built between research institutions where professors and students could do the same thing. And this could easily be followed by a militarized version where thoughts are communicated instantly between command centers and bunkers to ensure maximum clarity and speed of communication. My how the world is shaping up to be a science fiction novel!


The Birth of an Idea: The Computer Coat!

optical_computer1I’ve been thinking… which is not something novel for me, it just so happens that my thoughts have been a bit more focused lately. Specifically, I have an idea for an invention: something futuristic, practical, that could very well be part of our collective, computing future. With all the developments in the field of personal computing lately, and I my ongoing efforts to keep track of them, I hoped I might eventually come up with an idea of my own.

Consider, the growth in smartphones and personal digital assistants. In the last few years, we’ve seen companies produce working prototypes for paper-thin, flexible, and durable electronics. Then consider the growth in projection touchscreens, portable computing, and augmented reality. Could it be that there’s some middle ground here for something that incorporates all of the above?

Pranav Mistry 5Ever since I saw Pranav Mistry’s demonstration of a wearable computer that could interface with others, project its screen onto any surface, and be operated through simple gestures from the user, I’ve been looking for a way to work this into fiction. But in the years since Mistry talked to and showed off his “Sixth Sense Technology”, the possibilities have grown and been refined.

papertab-touchAnd then something happened. While at school, I noticed one of the kids wearing a jacket that had a hole near the lapel with a headphones icon above it. The little tunnel worked into the coat was designed to keep the chord to your iPod or phone safe and tucked away, and it got me thinking! Wires running through a coat, inset electrical gear, all the advancements made in the last few years. Who thinks about this kind of stuff, anyway? Who cares, it was the birth of an idea!

headphonesFor example, its no longer necessary to carry computer components that are big and bulky on your person. With thin, flexible electronics, much like the new Papertab, all the components one would need could be thin enough and flexible enough to be worked into the inlay of a coat. These could include the CPU, a wireless router, and a hard drive.

Paper-thin zinc batteries, also under development, could be worked into the coast as well, with a power cord connected to them so they could be jacked into a socket and recharged. And since they too are paper-thin, they could be expected to move and shift with the coat, along with all the other electronics, without fear of breakage or malfunction.

flexbatteryAnd of course, there would be the screen itself, via a small camera and projector in the collar, which could be placed and interfaced with on any flat surface. Or, forget the projector entirely and just connect the whole thing to a set of glasses. Google’s doing a good job on those, as is DARPA with their development of AR contact lenses. Either one will do in a pinch, and could be wirelessly or wired to the coat itself.

google_glass1Addendum: Shortly after publishing this, I realized that a power cord is totally unnecessary! Thanks to two key technologies, it could be possible to recharge the batteries using a combination of flexible graphene solar panels and some M13 peizoelectric virus packs. The former could be attached to the back, where they would be wired to the coats power system, and the M13 packs could be placed in the arms, where the user’s movement would be harnessed to generate electricity. Total self-sufficiency, baby!

powerbuttonAnd then how about a wrist segment where some basic controls, such as the power switch and a little screen are? This little screen could act as a prompt, telling you you have emails, texts, tweets, and updates available for download. Oh, and lets not forget a USB port, where you can plug in an external hard drive, flash drive, or just hook up to another computer.

So that’s my idea, in a nutshell. I plan to work it into my fiction at the first available opportunity, as I consider it an idea that hasn’t been proposed yet, not without freaky nanotech being involved! Look for it, and in the meantime, check out the video of Pranav Mistry on TED talks back in 2010 when he first proposed 6th Sense Tech. Oh, and just in case, you heard about the Computer Coat here first, patent pending!
