Description
A LOCATING KEY FOR A KEYBOARD OR KEYPAD
Field of the Invention The present invention relates to keys on a keyboard or keypad. More particularly, though not exclusively, the invention relates to locating keys for a computer or electronic keyboard or keypad which improves keyboard/keypad operating skills.
Background of the Invention A substantial number of modern electronic devices are equipped with a keyboard or keypad of some sort for manually inputting commands into the devices. The most common form of keyboard is that of the common household and business PC
keyboard ~o and the most common form of keypad is that of a mobile phone.
Referring to the keyboard, the most widely recommended method of input using one of the common keyboards is the "touch typing" method. This method simply trains a user to memorise the keyboard layout so thoroughly that they may type using all their fingers without looking at the keyboard. This method is achieved by constant practice and assigning each finger to a particular group of keys.
In particular, the "touch typing" method places each respective finger lightly on a "home" key, for example, in the "qwerty" keyboard these home keys are "asdf ' and "jkl;" from left to right. The thumbs are then placed over the space bar. Each finger rests lightly on its home key and does not move unless it reaches to strike keys immediately Zo above or below the home key or in the case of each of the index fingers, the keys immediately to the side of the home key, then the finger quickly returns to its home key.
Thus, each finger has only certain keys that it should strike.
Untrained keyboard operators use what is called the "hunt and peck" system.
Usually they use only their two forefingers or at most their four best fingers, the is forefinger and middle fingers. This method requires that the typist keeps their eyes on the keyboard and this affects productivity. Although some of these typists can type about as fast as touch typists, very fast hunt and peck typing is more tiring than for the touch typist because the hands have to leap all around the keyboard to reach all the keys with only two or four fingers. In summary, to "keyboard" correctly, the typist must use the touch typing method described above. There is no middle ground in proper typing; if the typist is not typing correctly, he is typing incorrectly. Similar problems arise in the use of keypads.
In an attempt to overcome the shortcomings of some of the prior art, many alternate shaped keyboards have been developed. One such keyboard is the KINESIS
keyboard (for example, US 6,005,496 to Hargreaves, et al) which describes a keyboard having two wells for the receipt of the right and left hands of a user. The advantage of such a keyboard is that the location of the wells allows a user's arms to extend straight out in front of the user thereby reducing the need for the user to move his or her hands along io the Keyboard. However, these types of keyboards are complicated to operate and rely on the user to memorise lcey combinations and macros.
Many other patterns such as US 1,823,130; US 3,396,827; US 3,848,723; US
5,515,763 and US 4,180,336, for example, describe keys for keyboards having top surfaces including longitudinal ridges, slots, rows of ridges, knobs, craters and texturing.
n Various combinations of texturing are also known.
Therefore, there still remains a need in the art for a keyboard and keypad that "forces" a typist to touch type correctly thus reducing typing inaccuracies and so minimising strain and effort.
Object of the Invention zo It is an object of the present invention to overcome or ameliorate some of the disadvantages of the prior art, or at least to provide a useful alternative.

The standard keyboard generally consists of a main alphanumeric body of at least three, but usually five, parallel, horizontal rows of keys (FIG. 1). The at least three rows could consist of a top row remote from a user, a middle row and a bottom row adjacent a user, the rows generally consisting of a series of alphanumeric keys followed by a series of function keys. For example, in Figure 1, each of the three middle rows 12, 13, 14 include a sequence of alphabetical and grammatical characters (such as the QWERTY or Dvorak sequence), bordered on the end of each row by modifier or function keys of some sort. That is, row 12 remote from the user has its alphanumeric keys starting with Q on the far left edge and finishing with P on the far right edge. Row 13 is ~o an intermediate row and has its alphanumeric keys starting with A on the far left edge and finishing with L on the far right edge. Similarly, row 14 being adjacent a user has its alphanumeric keys starting with Z on the far left edge and finishing with M on the far right.
The lowest row of keys 24, positioned closest to the typist (i.e., adjacent the ~ s user) and immediately under the lower of the middle three main rows 14, is generally made up of modifier or function keys on either end of a long spacebar 15. The second highest row of keys 16, positioned above the upper of the middle three main rows 12, is generally made up mainly of numerical keys. The highest row I 1 (remote from the user) is normally made up Of tL111Ct1011 keys.
zo While the horizontal rows 16, 12, 13, 14, 24 of the standard keyboard are usually aligned without deviation, the vertical alignment of the keys is usually staggered, and it is this specific juxtaposition of horizontal and vertical key relationships which make up the geometry of the standard keyboard 10 (FIG. 1 ). In particular, the reference for the vertical alignment shift is generally the home row, or middle row 13. The row 2, immediately beneath the home row, generally the lower alphabetical row, is usually organised in such a way that the keys of this row have their midpoints oriented in vertical alignment with or near the space between the keys of the home row 13. The row immediately above the home row 13, generally the upper alphabetical row, is usually organised in such a way that the keys of this row have their midpoints oriented in vertical 3o alignment with or near the left one-third vertical divider of the keys of the home row 13.
Finally, the row 16 immediately above the upper alphabetical row 12, which is the row above the home row 13, is usually organised in such a way that the keys of this row 16 W~ 00/78551 CA 02375208 2001-12-06 have their midpoints oriented in vertical alignment with or near the space between the keys of the row 12 immediately beneath them.
This general key relationship is the essence of what is usually referred to as the standard keyboard geometry (FIG. 1 ). While the specific organisation of the alphanumeric characters assigned to the keys of such a keyboard may vary, this does not affect the geometrical description of the keyboard 10, or its applicability to the modifications of the improved keyboard.
The foundation of the improved keyboard 20 the subject of at least a preferred embodiment of this invention, one variation of which is shown in FIG. 3, is the idea of io providing certain keys with the means of generating a specific feedback.
The feedback differs according to the position of the key and is such that the feedback of certain keys together, creates a virtual "box" within which the fingers can travel. In other words, the keys are so modified that a "wall" is created, which wall the fingers sense and within which wall they are guided (and almost forced) to operate. Therefore, not only the i s specific design of the keys gives that typist the exact feel for where the finger is, but also the key is so modified that they almost "force" the typist to stay within the "walls" that the modifications have created.
This in turn facilitates (and almost forces) the use of specific fingers on specific keys and eventually makes a typist proficient in the use of the correct fingers and thus Zo proficient in touch typing.
In the embodiment described here, the following keys of the standard QWERTY
keyboard have been modified:
1. The key "Q" 21 has a generally "L" shaped ridge 22 applied to the top border and to the left border (FIG. 2A). The ridge 22 is designed so that ?~ it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the upper left corner of an imaginary rectangular box 23 formed by the keys Q, W, E, R, F, V, C, X, Z, A. It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the left border.
2. The key "R" 24 has a generally "L" shaped ridge 25 applied to the top border and to the right border (FIG. 2B). The ridge 2~ is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the upper right corner of the same imaginary rectangular box 23 described in I above.
It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the left border.
3. The key "V" 26 has a generally "L" shaped ridge 27 applied to the bottom border and to the right border (FIG. 2C). The ridge 27 is co designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the lower right corner of the same imaginary rectangular box 23 described in 1 above. It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the is left border.
4. The key "Z" 28 has a generally "L" shaped ridge 29 applied to the bottom border and to the left border (FIG. 2D). The ridge 29 is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the zo lower right corner of the same imaginary rectangular box 23 described in I above. It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the left border.

The standard keyboard generally consists of a main alphanumeric body of at least three, but usually five, parallel, horizontal rows of keys (FIG. 1). The at least three rows could consist of a top row remote from a user, a middle row and a bottom row adjacent a user, the rows generally consisting of a series of alphanumeric keys followed by a series of function keys. For example, in Figure 1, each of the three middle rows 12, 13, 14 include a sequence of alphabetical and grammatical characters (such as the QWERTY or Dvorak sequence), bordered on the end of each row by modifier or function keys of some sort. That is, row 12 remote from the user has its alphanumeric keys starting with Q on the far left edge and finishing with P on the far right edge. Row 13 is ~o an intermediate row and has its alphanumeric keys starting with A on the far left edge and finishing with L on the far right edge. Similarly, row 14 being adjacent a user has its alphanumeric keys starting with Z on the far left edge and finishing with M on the far right.
The lowest row of keys 24, positioned closest to the typist (i.e., adjacent the ~ s user) and immediately under the lower of the middle three main rows 14, is generally made up of modifier or function keys on either end of a long spacebar 15. The second highest row of keys 16, positioned above the upper of the middle three main rows 12, is generally made up mainly of numerical keys. The highest row I 1 (remote from the user) is normally made up Of tL111Ct1011 keys.
zo While the horizontal rows 16, 12, 13, 14, 24 of the standard keyboard are usually aligned without deviation, the vertical alignment of the keys is usually staggered, and it is this specific juxtaposition of horizontal and vertical key relationships which make up the geometry of the standard keyboard 10 (FIG. 1 ). In particular, the reference for the vertical alignment shift is generally the home row, or middle row 13. The row 2, immediately beneath the home row, generally the lower alphabetical row, is usually organised in such a way that the keys of this row have their midpoints oriented in vertical alignment with or near the space between the keys of the home row 13. The row immediately above the home row 13, generally the upper alphabetical row, is usually organised in such a way that the keys of this row have their midpoints oriented in vertical 3o alignment with or near the left one-third vertical divider of the keys of the home row 13.
Finally, the row 16 immediately above the upper alphabetical row 12, which is the row above the home row 13, is usually organised in such a way that the keys of this row 16 W~ 00/78551 CA 02375208 2001-12-06 have their midpoints oriented in vertical alignment with or near the space between the keys of the row 12 immediately beneath them.
This general key relationship is the essence of what is usually referred to as the standard keyboard geometry (FIG. 1 ). While the specific organisation of the alphanumeric characters assigned to the keys of such a keyboard may vary, this does not affect the geometrical description of the keyboard 10, or its applicability to the modifications of the improved keyboard.
The foundation of the improved keyboard 20 the subject of at least a preferred embodiment of this invention, one variation of which is shown in FIG. 3, is the idea of io providing certain keys with the means of generating a specific feedback.
The feedback differs according to the position of the key and is such that the feedback of certain keys together, creates a virtual "box" within which the fingers can travel. In other words, the keys are so modified that a "wall" is created, which wall the fingers sense and within which wall they are guided (and almost forced) to operate. Therefore, not only the i s specific design of the keys gives that typist the exact feel for where the finger is, but also the key is so modified that they almost "force" the typist to stay within the "walls" that the modifications have created.
This in turn facilitates (and almost forces) the use of specific fingers on specific keys and eventually makes a typist proficient in the use of the correct fingers and thus Zo proficient in touch typing.
In the embodiment described here, the following keys of the standard QWERTY
keyboard have been modified:
1. The key "Q" 21 has a generally "L" shaped ridge 22 applied to the top border and to the left border (FIG. 2A). The ridge 22 is designed so that ?~ it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the upper left corner of an imaginary rectangular box 23 formed by the keys Q, W, E, R, F, V, C, X, Z, A. It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the left border.
2. The key "R" 24 has a generally "L" shaped ridge 25 applied to the top border and to the right border (FIG. 2B). The ridge 2~ is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the upper right corner of the same imaginary rectangular box 23 described in I above.
It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the left border.
3. The key "V" 26 has a generally "L" shaped ridge 27 applied to the bottom border and to the right border (FIG. 2C). The ridge 27 is co designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the lower right corner of the same imaginary rectangular box 23 described in 1 above. It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the is left border.
4. The key "Z" 28 has a generally "L" shaped ridge 29 applied to the bottom border and to the left border (FIG. 2D). The ridge 29 is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the zo lower right corner of the same imaginary rectangular box 23 described in I above. It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the left border.
5. The keys "A" 30 and ''F" 31 each have one ridge 32, 33 applied to the Zs left border in the case of the home key "A" 30 and to the right border in the case of the key ''F" 31 (FIG. 2E and FIG. 2F). These ridges 32, 33 are designed so that they provide the two fingers designated to use these keys with the feedback information that the fingers are in a "middle"
row since the feedback is that of a lateral ridge without a corner. In 30 other words, the finger senses that it is not in a "comer" position.
W~ 00/78551 CA 02375208 2001-12-06 pCT/AU00/00691 6. The lcey ''U" 34 has a generally "L" shaped ridge applied to the top border and to the left border (similar to as shown in FIG. 2A). The ridge is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard s namely, the upper left corner of an imaginary rectangular box 35 formed by the keys U, I, O, P, ;, /, >, <, M, J. It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the left border.

The ridge is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard s namely, the upper left corner of an imaginary rectangular box 35 formed by the keys U, I, O, P, ;, /, >, <, M, J. It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the left border.
7. The key "P" 36 has a generally "L" shaped ridge applied to the top io border and to the right border (similar to as shown in FIG. 2B). The ridge is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard namely, the upper right corner of the same imaginary rectangular box 35 described in 6 above. It should be noted, however, that the "L" shaped >> ridge could be formed by two separate ridges, one on the top border and one on the left border.
8. The key "M" 37 has a generally "L" shaped ridge applied to the bottom border and to the left border (similar to as shown in FIG. 2D). The ridge is designed so that it will provide a finger with the feedback 2o information that it has reached a specific position on the keyboard namely, the lower right corner of the same imaginary rectangular box 35 described in 6 above. It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the left border.
2, 9. The lcey "/" 38 has a generally "L" shaped ridge applied to the bottom border and to the right border (similar to as shown in FIG. 2C). The ridge is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard namely, the lower right corner of the same imaginary rectangular box 35 3o described in 6 above. It should be noted, however, that the "L" shaped ridge could be formed by two separate ridges, one on the top border and one on the left border.
10. The keys "J" 39 and ";" 40 each have one ridge applied to the left border in the case of the home key ".1" 39 and to the right border in the s case of the key "v" 40 (similar to as shown in FIG. 2E and FIG. 2F).
These ridges are designed so that they provide the two fingers designated to use these keys with the feedback information that the fingers are in the middle row of the same imaginary rectangular box 35 described in 6 above.
io In the same manner the numerical keys QWERTY keyboard 10 shown in FIG. 1, have been modified so that they provide the same positive feedback information and the fingers can operate within a "box" 41 formed by "walls" applied to the keys "7", "8", "9", "4", "6", "1 ", "2 and 3". It can be seen that the modifications are identical to those for similarly positioned keys of the alphabetical portion of the keyboard 20, except for keys na "8" 42 and "2" 43, thus:
1. The lcey "7" has a generally "L" shaped ridge applied to the top and to the left border (similar to as shown in FIG. 2A). The ridge is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the upper left zo corner of an imaginary rectangular box 41 formed by the keys 7, 8, 9, 6, 3, 2, 1, 4 2. The lcey "9" has a generally "L" shaped ridge applied to the top border and to the right border (similar to as shown in FIG. 2B). The ridge is designed so that it will provide a finger with the feedback information z, that it has reached a specific position on the keyboard 20 namely, the upper right corner of the same imaginary rectangular box 41 described in 1 above.
3. The lcey "3" has a generally "L" shaped ridge applied to the bottom border and to the right border (similar to as shown in FIG. 2C). The 3o ridge is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the lower right corner of the same imaginary rectangular box 41 described in 1 above.
4. The key "1" has a generally "L" shaped ridge applied to the bottom border and to the left border (similar to as shown in FIG. 2D). The ridge is designed so that it will provide a finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the lower left corner of the same imaginary rectangular box 41 described in 1 above.
5. The key "4" has one ridge applied to the left border (similar as shown in io FIG. 2E) which ridge is so designed so that it provides the finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the left middle edge of the same imaginary rectangular box 41 described in 1 above.
6. The lcey "6" has one ridge applied to the right border (similar as shown i; in FIG. 2F) which ridge is so designed so that it provides the finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the right middle edge of the same imaginary rectangular box 41 described in 1 above.
7. The key ''8" 42 has one ridge 44 applied to the top border (similar as Zo shown in FIG. 2G) which ridge is so designed so that it provides the finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the top middle edge of the same imaginary rectangular box 41 described in 1 above.
8. The key "2" 43 has one ridge 4~ applied to the bottom border (similar as is shown in FIG 2H) which ridge is so designed so that it provides the finger with the feedback information that it has reached a specific position on the keyboard 20 namely, the bottom middle edge of the same imaginary rectangular box 41 described in 1 above.
It can be seen that the identical modifications described above can be used if ~o desired to modify the directional keys 46 used to move the cursor around the screen of a computer and which are known as the "inverted T", or similarly the functional keys 47 ("Insert", "Home", "PageUp", "Delete", "End", "PageDown"), to obtain similar locational feel and feedback.
It can also be seen that the modifications described in number 4 and 6 above, can be used, if desired, to modify the keys "1 ", "4", "7", "0" 48 of the row 16 of the s QWERTY keyboard 10 of FIG.I one obtains similar locational feel and feedback.
Further keys of the QWERTY keyboard or similar keyboards could be modified such that the keys corresponding to "W", "E", "I", "O", all have a ridge applied to the top of the respective key similar to the ridge of the key "8" as described in number 7 above.
Similarly, keys "X", "C", "<", ''>", could also each respectively have a ridge applied to ~u the bottom of each respective key similar to the ridges of Icey "2" as described in number 8 above. In this way, a more defined "box" is obtained within which the fingers of the left or right hand are obliged to move.
It can therefore also be seen that a key having a ridge on a top or bottom border provides a geometric indicator stimulating the user as to the location of the finger within ~, the respective box. This also indicates whether the user's finger is parallel or normal to a particular row.
While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of one preferred embodiment thereof. For example, different standard keyboards can be zo similarly modified. Additionally, the ''walls" on the keys can be of different height, thickness, shape and appearance and still activate the feedback which is the subject of this invention. Additionally, this invention may be applied to keyboards or keypads molded to curved surfaces such as the "Microsoft Natural Keyboard" and equivalent keyboards, or using non-alphanumeric keys or designations, chording capabilities, single or multiple-z~ hand designs, or miniaturization. Additionally, the invention may be applied to keypads used on telephones, calculators, cash registers, electrical appliances and other electronic devices. The keys may be integral with the keypad or the ridges can be formed of plastic material with a self-adhesive backing for attachment to keys of a "normal"
keyboard or keypad.
