In this new era of technology, a computer is being developed called “the mind reading computers”. don’t worry those are not as small as a chip which can be inserted in your mind like in a sci-fi fiction movie there is a whole machine for it(BIG for now). I believe nanotechnology will replace this big machine into a smaller machine in future.
According to researchers at Intel who are behind a mind-reading computer project. They say, unlike current brain-controlled computers, which require users to imagine making physical movements to control a cursor on a screen, the new technology will be capable of directly interpreting words as they are thought.
Intel’s scientists are creating detailed maps of the activity in the brain for individual words which can then be matched against the brain activity of someone using the computer, allowing the machine to determine the word they are thinking.
The tests of the system have shown that the computer can work out words by looking at similar brain patterns.
Currently, a number of experiments in affective computing and HCI(Human-Computer Interaction) areas are being conducted. The mind-reading computer, genuinely, can read people’s minds and can react to different emotions or commands. Researchers believe that, in the future, the mind-reading computer can be applied to many disciplines in the real world and can improve the quality of HCI. To accomplish that, this research will be based on secondary data sources and will mainly focus on its effect on individuals as the main end-users.
- Oxygen and Blood Measure
The mind reading actually involves measuring the volume and oxygen level of the blood around the subject’s brain, using a technology called functional near-infrared spectroscopy (fNIRS). The user wears a sort of futuristic headband that sends light in that spectrum into the tissues of the head where it is absorbed by active, blood-filled tissues. The headband then measures how much light was not absorbed, letting the computer gauge the metabolic demands that the brain is making.
2. Mind Reading
1). Wheelchair- A successful application. This prototype mind-controlled wheelchair developed from the University of Electro-Communications in Japan lets you feel like half Professor X and half Stephen Hawking—except with the theoretical physics skills of the former and the telekinetic skills of the latter. This thing works by mapping brain waves when you think about moving left, right, forward or back, and then assigns that to a wheelchair command of actually moving left, right, forward or back.
2). Lie detection
- Blood oxygenation level-dependent (BOLD) fMRI could be sensitive to differences between lies and truth.
- Mertens & Allen (2008) discuss whether ERP-based procedures could detect deception, instead of or in addition to fMRI.
3). Pain detection
- Marquand et al. (2010) suggest that supervised machine learning algorithms can be used to decode fMRI data. They use this kind of technique to show that fMRI can be used to predict participants’ subjective pain ratings.
Direct brain communication in paralysis, motor restoration in stroke – Birbaumer & Cohen (2007) evaluate the use of EEG and fMRI in brain-computer interfaces, focusing on applications for paralyzed patients and for motor restoration in the case of stroke. Although currently, our understanding of the information flow in the brain that is required for such interfaces to work is incomplete, such interfaces will eventually be able to be used for direct brain communication and will allow otherwise “locked-in” patients to interact with the world.
4. Pattern analysis and future research
Norman et al. (2006) argue that fMRI data can be used in conjunction with sophisticated pattern-classification algorithms to decode the exact information represented in a patient’s brain at a particular moment in time. They discuss factors that would boost the performance of this method — it is possibly the most promising research toward actual mind-reading.
