What's the major difference between mind and brain? I am preparing a presentation on "Mind Reading Computer", and all articles that I came across were focused on reading interpretations from brain through sensors. Articles like  this clearly show a distinction between them, but from an engineering perspective, I need scientific facts. Does "mind reading computer" imply "brain reading computer", or does the term "mind" have totally a different meaning in the context? Any help and facts relating to the topic will be highly appreciated!
Wikipedia is often a good place to start for basic questions like these. Wikipedia has separate pages devoted to the mind, the brain, and even the mind–body problem, which is one example of the many theoretical challenges implied by the distinctions between "mind" and "brain". Simply stated:


The brain is a physical organ. It's entirely possible that much of its structure has relatively little bearing on the nature of the mind. For instance, glial cells are more numerous than neuronal cells. Glial cells play a relatively more supportive function than neurons, the direct functions of which may be more closely related than glial cells' to the functions of what we consider to constitute the mind.
Wikipedia describes the mind as, "The set of cognitive faculties that enables consciousness, perception, thinking, judgement, and memory." Google offers this primary definition: "The element of a person that enables them to be aware of the world and their experiences, to think, and to feel; the faculty of consciousness and thought." Neither of these definitions directly necessitate a physical substrate such as the brain. However, The Free Dictionary's primary definition includes the phrase, "Originates in the brain." These differences belie the controversiality of the term itself, as does @KeeganKeplinger's helpful answer.
Wikipedia's mind page has a section dedicated to its relation to the brain. This section mentions the mind–brain problem, as well as three philosophical stances on the problem:

Materialism: briefly, that there is no valid distinction, and all mental activities have neural bases
Idealism: essentially that all physical objects and processes are truly mental in nature
Dualism: that the mind exists somewhat independently of the brain and body, possibly as an aspect or property of the spirit or soul



Thus a simple answer would be that "mind" does imply "brain" for many if not most audiences, but some may opine that these are different (though probably not totally different) entities. Arguably the best approach would be to tailor your word choice to suit whichever entity your computer concept proposes to read most directly.
