Up until now, we have been looking at software in which we enter text by typing on the keyboard. Recent developments in automatically entering text have centred on voice recognition, where the user speaks into a microphone, and handwriting recognition, where the user writes using a special pen. Both will then convert the data input into a word-processed document. Both of these technologies are improving rapidly. Using optical character recognition software, it is possible for the computer system to read text into the computer directly as a word-processed document. A sheet of paper with typed text is placed on a scanner that scans the sheet of paper. The OCR software then searches for shapes of letters it recognises and converts them into a word-processed document. The main drawback of optical character recognition software is the limited number of characters it can recognise; therefore mistakes are made. For example, a 1(one) and an l(letter l) are often confused. Similarly with a 5(five) and an S(letter S). Answer the following questions in your jotter.
