Concept keyboards

For persons who have cognitive difficulties, we can increase access by using concept keyboards. These keyboards replace the letters and numbers of the keyboard with pictures, symbols, or words that represent the concepts required by the software. For example, a program designed to teach monetary concepts might use a concept keyboard in which each key is a coin rather than a number or letter. The user can push on the coin and have that amount entered into the program. Such keyboards have been used in point-of-sale applications to allow individuals who have intellectual disabilities to work as cashiers. The Intellikeys keyboard is often used as a concept keyboard. 

Records held in memory, e.g., temperature profile from an Antoclave, and retained for a period (say, 10 batches) to enable reprint, should not be disconnted as an electronic record on the grounds that it is not committed to dnrable media. Althongh the record may not have yet been saved to dnrable media, it may still be vnlnerable to nnanthorized alternation. FDA dnrable media concept was intended to exempt the keyboard buffer from audit trails. The example cited raises data integrity issnes. 

At the second level is the use of the computer in a laboratory-like setting to accompany and support the quantum chemistry lectures. In the 1970s an effort was begun to develop a series of computer exercises that could serve as the laboratory component for theoretical chemistry. Students find quantum chemistry to be an abstract, highly mathematical subject, and unless its concepts are translated into action in some way it is unlikely that they will master its principles or discover its applications in other disciplines. Hands on in quantum chemistry means hands on the keyboard of a computer. Therefore, the goal was to create a repertoire of computer exercises that juxtaposes the theoretical framework of quantum chemistry and its computational methodology.
