Definitions
- This invention relates to keyboards, and more particularly to a keyboard adapted for one-handed
- Sholes which has become a worldwide standard.
- a typist rests his or her fingers on the home-rows keys (i.e. the fingers of the left on the letters A S D F, and the fingers of the right hand on J K L).
- the left hand governs operation of the left half of the keyboard while the right hand governs operation of the right half. All of the other keys are struck according to their position relative to the home-row keys.
- the keys for 3 and E are above the D key, while the C key is below. Therefore, these four keys may all be struck by the same finger of the left hand (i.e. the finger that usually rests on the D key).
- a "shift" key is also normally provided for
- a disadvantage of traditional two-handed QWERTY design is that the keyboard is quite large, and the keys must be angularly offset to accommodate both arms of a typist being separated by his or her rib cage.
- States Patent 4,555,193 discloses the principle of assigning two or more letters/characters to each key of the keyboard and incorporating a modifier key to switch between the letters/characters in a one-handed layout.
- the modifier key for selecting a particular letter is the key having the same background color as the letter to be selected.
- United States Patent 4,180,337 discloses an arrangement of keys on a keyboard in which each letter of the alphabet is represented by an individual key, with the keys being arranged in five primary rows.
- the invention of Hilborn et al includes an alphabetical arrangement of letters.
- the user depresses more than one key at a time.
- the thumb may depress either of four keys or any two adjacent keys while a finger concurrently presses one key, two keys next to each other or
- an alphanumeric keyboard is provided making possible one-handed touch-typing, while at the same time capitalizing on the wide spread acceptance of and proficiency already attained in the operation @f traditional keyboard layouts.
- a one-handed keyboard comprising:
- a modifier key for controlling said means for assigning to switch between said one half and said other half of said keyboard, thereby providing one-handed operation of said keyboard using standard touch-typing techniques.
- Figure 1 illustrates a standard QWERTY keyboard split roughly in half at the point where left and right hand keys meet
- Figure 2 illustrates a one-handed QWERTY keyboard in accordance with a preferred embodiment of the present invention
- Figure 3 illustrates the right hand field of the keyboard shown in Figure 2;
- Figure 4 illustrates the left hand field of the keyboard shown in Figure 2;
- Figure 5 illustrates a one-handed left hand QWERTY keyboard in accordance with a first alternative
- Figure 6 illustrates a one-handed left hand DVORAK keyboard in accordance with a second alternative
- Figure 7 illustrates a one-handed right hand DVORAK keyboard in accordance with a third alternative
- a standard QWERTY keyboard is shown split roughly in half at the point where the left and right hand keys meet.
- a typist rests his or her fingers of the left hand on A S D F and the right hand on J K L.
- each left hand finger strikes keys on the left hand side of the keyboard which are symmetrically opposite to the keys struck by the corresponding finger of the right hand on the right side of the keyboard.
- the D key and the K key are meant to be struck by the middle fingers of the left hand and right hand, respectively.
- a one-handed half-keyboard could be provided in which letters of the missing half of the keyboard are arranged to correspond exactly to their original hand pattern except on the other hand.
- the keyboard is modelled on standard QWERTY layout, and adapted for typists who wish to type with their right hand. All letters struck by the same finger of either hand occupy their respective positions relative to the corresponding key in a full sized QWERTY keyboard (e.g. the D key on the left and the K on the right are struck by the same finger).
- the keyboard acts exactly like the right half of a standard keyboard, as illustrated with reference to Figure 3.
- the ⁇ key functions as the modifier key for switching between left and right hand fields of the keyboard layout.
- Figure 5 illustrates a left-hand QWERTY keyboard while Figure 6 represents a left-hand DVORAK.
- Figure 7 illustrates the layout for a
- the one-handed keyboard of the present invention may be manufactured according to known industrial techniques, and performs the utilitarian function of enabling input of alpha-numeric information using only one hand.
- the one-handed keyboard of the present invention benefits from numerous advantages over standard two-handed full-QWERTY layout design. For instance, the keyboard is more compact, being over one third smaller than a full-sized two-handed keyboard. This allows for the design of smaller computers and word processors without sacrificing the ability to touch-type.
- the design of the present invention requires only one hand for operation. Thus, the other hand of the typist is left free for hand writing, control of a mouse/joystick, etc. Physically handicapped persons who may only have the use of one hand, are able to touch-type with the keyboard of the present invention.
- the one-handed keyboard of the present invention can actually generate more characters than a standard full-sized keyboard.
- the one-handed keyboard of the present invention generates at least two characters for every key on the keyboard, and twice the number of keys on the present one-handed keyboard exceeds twice the number of keys on one half of the prior art two handed keyboard (see Figures 1 & 2).
- the one-handed keyboard of the present invention is horizontally symmetrical. Therefore, there need not be any physical difference between a left and a right hand keyboard, thus allowing concurrent production of left and right hand keyboards without the increase in production costs that is characteristic of prior art two-handed keyboards having angularly offset keys.
- This also allows for remapping of the keyboard to form a numeric keypad (e.g. telephone key pad).
- the problem of prior art two-handed keyboards is not present with the one-handed keyboard of the present invention, since the typist, s arm does not protrude at an angle. Instead, the typist, s arm extends perpendicularly of the keyboard. Therefore, the keys need not be
- slanted They may be arranged in a more comfortable and more convenient orthogonal grid pattern.
- One major strength of the one-handed keyboard of the present invention is that it does not abandon the
- a touch-typist can begin typing almost immediately on the one-handed keyboard of the present invention since learning time is reduced to a minimum.
- Non-letter symbols on the keyboards of the present invention need not be in the positions (or shapes) shown in Figures 2-7. There is often variation among
- modifier keys for obtaining even more characters.
- These modifier keys could be placed in any location (and in whatever shape) that is convenient.
- the keys on the one-handed keyboard of the present invention as shown with reference to Figures 2-7 are arranged in orthogonal grid pattern. For one-handed typing, this layout is thought to be most convenient and most comfortable. However, the keys need not arranged as such.
- a one-handed keyboard could be arranged with keys disposed at an angle, as with traditional full-sized keyboards.
