Input Device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance. A keyboard is the most common input device. Using a keyboard‚ the user can type the text and execute commands. Keyboard is designed to resemble a regular typewriter with a few additional keys. Data is entered into the computer by simply pressing various keys. The layout of a keyboard comes in various

Data Input Methods Optical data readers The best data input method for printed questionnaires would be Optical Data Readers. Optical Data Readers are a special type of scanning device to be used on documents. Optical Data Readers fall under two categories‚ optical mark recognition (OMR) and optical character recognition (OCR) (Stair‚ R.‚ Reynolds‚ G.‚ 2004). Printed questionnaires which‚ for instance‚ can be used for surveying groups of people regarding a particular subject can utilize OMR through

Abstract This paper is about a selected few image processing applications. Optical Character Recognition is the translation of images of handwritten‚ typewritten or printed text into machine-editable text. Then I have introduced the captcha that we so frequently encounter in common websites. An algorithm trying to solve or break a captcha has been explained. Face detection is a growing and an important tool in security these days. It must be applied before face recognition. There are many

because of their inability to distinguish illusions and reality. Throughout the play‚ hallucinations recur as a reminder to Macbeth and Lady Macbeth of their murders. Shakespeare reveals in Macbeth that being able to determine reality from illusion is essential for sanity and human survival. There are many ways in which illusions cause Macbeth’s downfall throughout the play. At the beginning of the play‚ Macbeth is visited by the three witches‚ illusions that Banquo told him not to trust‚ who tell
