摘要：Recognizing the need for facilitating interactive, non-oral communication with visually impaired individuals, it is a general object of the present invention to provide a novel writing surface which allows interactive communication with the visually impaired and minimizes or reduces the problems encountered with the devices of the prior art. It is an additional object of the invention to provide a method for producing such a writing surface. It is also an object of this invention to provide a writing kit comprising the aforementioned writing surface and a specially adapted writing fluid. More particularly, this invention provides a writing material suitable for use by visually impaired individuals comprising a cellulosic substrate formed into a sheet having at least a first surface. The sheet is characterized in that when a writing fluid is applied to the first surface in a desired pattern, an expansion occurs to produce a pattern readable by touch, wherein said pattern is readable by touch as the pattern in which the writing fluid was applied and remains readable by touch after drying of the writing fluid.
