There are BCI's that can be invasive or non invasive which requires a eeg headset. In both brain waves are recorded by the computer and decoded for video and thought reconstruction of the brain waves. But is it possible to do the same from a distance without any other hardware except the computer having the BCI software installed.?
This is a Hypothetical scenario as of today..as far us present scenario there may not be effective methods or tools which can produce such waves which can be perceived by neurons of the brain. However distance stimuli is possible through visual stimuli ( checkboard pattern screen) instead of auditory stimuli ( headphone). Exploring the VEP stimuli can be possible solution ..
Sorry, but not the sort of answers I am looking for. Invasive and Non invasive BCI's are very common nowadays. But I am looking for some real technology within a computer that could interact with the brain without any eeg headsets or chips implanted in brain. Thanks.
Way back in 2002, Terry Clark then of the Unviersity of Sussex (and perhaps still there) developed a sensor that can record brainwaves without the need for electrodes to be inserted into the brain or even for them to be placed on the scalp. Instead of measuring charge flow through an electrode (with attendant distortions, in the case of scalp electrodes) the system apparently measures electric fields remotely. CHeck it out
Thanks. That is a very good option. If you can send me any link would be great.

Thank You for your answer Dr. Gerry Leisman. Would look forward towards getting more support from you in future.
