Typing Considerations


This page covers the following topics:


Typing Style

Touch Typing

Touch typing is a structured way of achieving fast typing speeds without looking at the keyboard. Rules for touch typing are:

  • Posture
    • Feet flat on floor (one foot is slightly forward)
    • Sit straight and tall
    • Lean forward at the waist
  • Arm and Hand
    • Elbows close to the side
    • Forearms slanted upward (elbows less than 90°)
    • Fingers curved and resting on the home keys
    • Wrists are up (i.e. wrists are not resting on the desk or a wrist rest)

Non-Touch Typing

There are probably as many different non-touch typing styles as there are people who use this method of keyboarding.

  • No rules defining posture or positioning.
  • The number of fingers involved in typing varies from:
    • One finger (usually the index finger) on one hand, called the “hunt and peck” method.
    • Both index fingers.
    • Some combination of fingers, usually the index fingers, middle fingers (3rd digit) and the thumbs for striking the space bar.
  • While touch typing is primarily finger movement (with small amounts of wrist movement), non-touch typing has much more gross motor movement:
    • Elbow movement to raise the hand.
    • Shoulder rotation – especially to strike the Enter key.
    • Wrist movement is greater than for touch typing – especially ulnar deviation (ulnar flexion).
    • Some shoulder flexion to reach the number keys at the top of the keyboard.
  • These movements will vary based on the experience of the user:
    • Inexperienced user: will have greater shoulder and wrist movements as they search for keys.
    • Experienced user: subconsciously become familiar with the keyboard and movements become more efficient – more wrist than shoulder and elbow.
  • Non-touch typists must see the keys of the keyboard. This results in frequent up and down movements of the head, as the operator looks down to type, looks up to check what they wrote and then looks down to type again.

Typing History

Typing started with typewriters, which are constructed with four tiers of keys, with each tier higher than the tier in front. In front of the first tier is the space bar. Keys are spaced further apart than on a computer keyboard. Touch typing on a typewriter required more shoulder movement and more elbow flexion, in order to reach the higher keys, than it does on a computer keyboard.


IBM Selectric Typewriter

Of course different manufacturers developed different variations of the typewriter. The key section of the IBM Selectric was similar to today's computer keyboards (keys close together and far less stacking of the rows):

Corona Typewriter

With the shift to computer keyboards, touch typists who had worked on typewriters had to adjust to a keyboard that was essentially flat. However, to try to approximate the height of a typewriter, computer keyboards had a built in positive tilt (high at the back) and had extendible feet to allow the back to be raised even higher.


Keyboard Tilt

Keyboard tilt is defined as either positive or negative tilt. The benefits of tilting a keyboard is a source of a great deal of debate.


Definition of Keyboard Tilt

If the closest row of keys (including the space bar) is lower than the furthest row of keys (usually the function keys) then the keyboard has a positive tilt. Essentially the keyboard is getting higher the farther away your hands travel. Most economical keyboards have a degree of positive tilt as part of their design. In addition they usually have extendible feet that allow you to increase the amount of positive tilt.

Some keyboards have no built-in tilt, with all keys at the same height.

Seeing the Keys

Most non-touch typists, or hunt and peck typists, must be able to see the keys of the keyboard while typing. The greater the amount of negative tilt the more difficult it becomes for the operator is to see the keys. This does not pose a problem for touch typists, but those who use a hunt and peck system might find that being unable to see the keys creates additional problems. People who type via a hunt and peck method, and who have negative keyboard tilt, have a tendency to lean forward so they can see the keys. This can contribute to neck and other postural discomfort.


Some keyboards are constructed such that it is difficult to see some or all of the keys while typing.
