Mind reading computer is defined as equipment which deduces the mental state of a human being. To understand a human being’s thought is one of the most difficult tasks. No one comes to know about what other person would actually do in up coming seconds by carrying out his present notion of thought or what a person thinks about the other person or what is he desiring at the present moment and many more. The mind reading computer can be a better solution for this as it could give you the answer of all such questions.
Mind reading computer deduces the thoughts and notions of a person which are based upon the various technologies for example by scrutinizing the expressions of the face along with the head gestures and then identifies the volume of the blood including the oxygen level inside the blood which flows in the brain vicinity.
With the exponential development in technologies, we can assume that in future we may have enormous amount of technology that will lead to the making of a perfect mind reading computer. This ability of a computer to read minds can offer us a lot of applications especially in the field of crime, medical and an individual’s life too.
Predicted Work of a Mind Reading Computer:-
A team from University of Cambridge have been working on this model (mind reading) in the corresponding computer laboratory .They have developed the mind reading machines which implements the computational model for mind reading in order to deduce the mental states of a person from their head gestures and facial expressions. This machine employs by making use of digital video cameras that analyse an individual’s facial expression thereby deducing a person’s fundamental mental state like thinking, interested, agreeing, bored, sad, happy and angry.
Having some knowledge of how a particular mental state is and then having some knowledge of how it is expressed by the facial expression and corresponding head gestures and then eventually storing it in a database of the mind reading machine. Afterwards, the machine can give the particular mental state. This model represents them at different numbers i.e. storing the head and face movement’s in a database and then representing them in 3D space in order to form the clear and concise model of a particular mental state represented by head gestures and facial expressions. A software from Navension Company detects 22 basic feature points of a face and then tracks them in the real time. Colour, Shape and Movement are the basic parameters that are analysed to recognize certain gestures such as open mouth and closed eyes (half).Combination of these parameters occurring in real time indicates the particular mental state. For example if an eyebrow is raised inwards, it might indicate thinking.
Estimation of Head Pose:-
It uses expression invariant features to estimate yaw(500),roll(300) and pitch(500) such as to estimate the head yaw by using the ratio of the left point to the right point of an eye width and estimating head roll by making use of angle between two inner corners of the eye.
Facial Expressions are recognized by some feature points comprising shape, colour and motion descriptors. The tracking of lip shape that recognizes corner pull of the lip (smile) and the distance between each of the mouth corner and anchor point is calculated and analysed using the machine.
Applications and Advantages of Mind Reading Computer:-
This mind reading computer can be of a greater and wider importance if used wisely and judiciously. It can help in mind reading of a person (although with not 100% accuracy) which inturn could let other person to know how this particular person thinks in real sense. So making judicious use of this machine it could help out in solving many critical problems.
