The melding of humanity with the technology we have created has begun…

We are well on our way as Homo sapiens to becoming a species that fully merges technology with our organic bodies. In some ways, we’ve been getting at this for centuries already, beginning with the first use of eyeglasses, at the end of the thirteenth century in Italy, to improve vision by making it easy for someone to wear two magnifying lenses on the bridge of their nose.

But ever since the invention of the computer and the first human-machine interfaces were born (HMIs), a dream of many technologists has been to create direct connections between computers and the human brain. These brain-computer interfaces (BCIs) — also known as Brain-Machine Interfaces (BMIs) — would eliminate the lag inherent in the translation between thought → physical action → computer response. BCIs also allow people who cannot perform physical actions required for HMIs to bypass that real-world step and directly control powerful computer tools with the electrical impulses in their brains.

One of the dreams is that BCIs will eventually place the entire canon of human knowledge within the realm of immediate recall: No more searching the internet via typing or voice commands needed. In a near future, we will be able to think about what we need and pull whatever relevant information is available directly from a cloud and into the forefront of our minds.

Digital tattoo for controlling devices with your mind

For around $120, anyone can can buy a headset that reads the electrical activity of their brain. It’s called an electroencephalogram, or EEG, a devise that reads the electrical activity of their brain, and you can use it to control devices with the power of your mind.  But there are some drawbacks:  they don’t work when the wearer is moving and they look silly, so no one wants to wear them.   Continue reading… “Digital tattoo for controlling devices with your mind”

Two-way ‘conversations’ possible with vegetative state patients

The brainwaves were assessed using an electroencephalography (EEG) machine.

Neuroscientists discover that two-way “conversations” with people in a permanent vegetative state will be possible thanks to an inexpensive device that can read their brain activity.
