Basic Typing Methods: Lessons - U.S. Navy Training Film (1944) http://thefilmarchive.org/ Typing is the process of inputting text into a device, such as a typewriter, cell phone, computer, or a calculator, by pressing keys on a keyboard. It can be distinguished from other means of input, such as the use of pointing devices like the computer mouse, and text input via speech recognition. The world's first typist was Lillian Sholes from Wisconsin. She was the daughter of Christopher Sholes, the man who invented the first practical typewriter. User interface features such as spell checker, autocomplete, and autoreplace serve to facilitate and speed up typing and to prevent or correct errors the typist may make. The basic technique stands in contrast to hunt and peck typing as the typist keeps their eyes on the source copy at all times. Touch typing also involves the use of the home row method, where typists keep their wrists up, rather than resting them on a desk or keyboard as this can cause carpal tunnel syndrome. To avoid this, typists using this method should sit up tall leaning slightly forward from the waist, place their feet flat on the floor in front of them with one foot slightly in front of the other, keeping their elbows close to their sides with forearms slanted slightly upward to the keyboard, fingers should be curved slightly resting on the home row (asdfjkl;). Many touch typists also use keyboard shortcuts or hotkeys when typing on a computer. This allows them to edit their document without having to take their hands off the keyboard to use a mouse. An example of a keyboard shortcut is touching the Control key plus the S key to save a copy as you type, or the Control key plus the Z key to undo a mistake. Many experienced typists can feel or sense when they've made an error and can hit the backspace key and make the correction without missing a beat. A highly trained touch-typist on a Dvorak keyboard is the second-fastest method of English text entry available as of 2007. (The fastest text entry method involves a highly trained typist on a stenotype keyboard.) Hunt and peck (two-fingered typing), also known as search and peck, is a common form of typing, in which the typist must find and press each key individually. This is usually slower than touch typing. Instead of relying on the memorized position of keys, the typist must find each key by sight. Use of this method may also prevent the typist from being able to see what has been typed without glancing away from the keys. Although good accuracy may be achieved, any typing errors that are made may not be noticed immediately, if at all. There is also the disadvantage that because fewer fingers are used, they are forced to move a much greater distance. There are many idiosyncratic typing styles in between "hunt and peck" and touch typing; for example, many people will type blindly, but use only two to five fingers, and not always in a systematic fashion. Some people have developed advanced forms of "peck minus hunt" that don't require looking at keys, or sacrifice of speed. Some people combine touch typing and hunt and peck by using a buffering method. In the buffer method, the typist looks at the source copy, mentally stores one or several sentences, then looks at the keyboard and types out the buffer of sentences. This eliminates frequent up and down motions with the head and is used in typing competitions in which the typist is not well versed in touch typing. It is not normally used in day-to-day contact with keyboards, only when time is of the essence. A late 20th century trend in typing, primarily used with devices such as PDAs with thumb keyboards or smartphones with small virtual keyboards, is thumbing or thumb typing. This can be accomplished using one or both thumbs. Similar to desktop keyboards and input devices, if a user overuses keys which need hard presses and/or have small and unergonomic layouts, it could cause thumb tendonitis or other repetitive strain injury. http://en.wikipedia.org/wiki/Typing Tags: 1940s, age, antique, army, benton, communication, course, educational, electric, enthusiast, ergonomics, female, film, free, fundamentals, gender, girls, help, history, ii, learn, lenore, lesson, lessons, machines, manual, men, military, narrator, naval, navy, need, paper, personnel, pre-computer, roles, school, short, short film, skills, student, teacher, teaching, tips, training, tricks, tutor, tutorial, typewriters, typing, vintage, war, warfare, women, world 1 Downloads - Last from: http://downthisvideo.com/ (Your Blog here!) |
