Input Mask
In computer programming, an input mask refers to a string expression, defined by a developer, that constrains user input. It can be said to be a template, or set format that entered data must conform to, ensuring data integrity by preventing transcription error A transcription error is a specific type of data entry error that is commonly made by human operators or by optical character recognition (OCR) programs. Human transcription errors are commonly the result of typographical mistakes; putting one's ...s. The syntax of this string expression differs between implementations, but the fundamental input types are all supported. Some frequent uses of input masks include entry of telephone numbers, ZIP or postal codes, times and dates. :e.g. When entering into a text box a phone number on a data capture form, in the format "(111) 111 1111" the area code brackets, the space between the number and the area code will automatically be placed in. Generally speaking, an input mask is a ...

Data Integrity
Data integrity is the maintenance of, and the assurance of, data accuracy and consistency over its entire Information Lifecycle Management, life-cycle. It is a critical aspect to the design, implementation, and usage of any system that stores, processes, or retrieves data. The term is broad in scope and may have widely different meanings depending on the specific context even under the same general umbrella of computing. It is at times used as a proxy term for data quality, while data validation is a prerequisite for data integrity. Definition Data integrity is the opposite of data corruption. The overall intent of any data integrity technique is the same: ensure data is recorded exactly as intended (such as a database correctly rejecting mutually exclusive possibilities). Moreover, upon later Data retrieval, retrieval, ensure the data is the same as when it was originally recorded. In short, data integrity aims to prevent unintentional changes to information. Data integrity is no ...

Transcription Error
A transcription error is a specific type of data entry error that is commonly made by human operators or by optical character recognition (OCR) programs. Human transcription errors are commonly the result of typographical mistakes; putting one's fingers in the wrong place while touch typing is the easiest way to make this error. Electronic transcription errors occur when the scan of some printed matter is compromised or in an unusual font – for example, if the paper is crumpled, or the ink is smudged, the OCR may make transcription errors when reading. Transposition error "Transposition error" may be confused with "transcription error", but they do not mean the same thing. As the name suggests, transposition errors occur when characters have “transposed”—that is, they have switched places. This often occurs in the course of transcription; thus a transposition error is a special case of a transcription error. Transposition errors are almost always human in origin. The mo ...

User Interface Techniques
An interaction technique, user interface technique or input technique is a combination of hardware and software elements that provides a way for computer users to accomplish a single task. For example, one can go back to the previously visited page on a Web browser by either clicking a button, pressing a key, performing a mouse gesture or uttering a speech command. It is a widely used term in human-computer interaction. In particular, the term "new interaction technique" is frequently used to introduce a novel user interface design idea. Definition Although there is no general agreement on the exact meaning of the term "interaction technique", the most popular definition is from the computer graphics literature: A more recent variation is: The computing view From the computer's perspective, an interaction technique involves: * One or several input devices that capture user input, * One or several output devices that display user feedback, * A piece of software ...
