Philosophy signifies the love of wisdom, it search for truth, not easy truth, It search for eternal truth, reality and common principles of life. Examples of adaptive technologies incorporate mobility devices (walkers, wheelchairs, and so forth.), FM and/or sound field systems (for students with hearing impairments), braillers or print enlargers (for students with visual impairments) and personal care things. In addition to AT, some students with learning disabilities may also have physical or healthcare conditions that necessitate specialized adaptive equipment to access the curriculum and/or option plan. This may perhaps be because the student is obtaining them openly on the web, or for the reason that tutors, teachers and lecturers are themselves recommending sources.
