## Abstract

A method of arranging keys of soft keyboard in specific, non rectangular shapes to provide wider width for keys in portrait mode and higher height for keys in landscape mode. Keys are shaped in the way that allows to be aligned in a complementary manner. For portrait mode keys are complementarily aligned on X axis and for landscape mode keys are complementarily aligned on Y axis.

## Claims

### Claim 1

In a computer system having a soft keyboard a method of providing keys to a user for data input, comprising shaping keys in a non-rectangle form to provide wider width in portrait mode and to provide higher height in landscape mode wherein key shapes allow to be complementarily aligned; in portrait mode keys are shaped with wider width on the either bottom or top edge and narrower width on the opposite edge; in landscape mode keys are shaped that has a peak height either on one side or in the middle of the keys.

### Claim 2 (depends on 1)

The method of claim 1, wherein shaping keys in a non-rectangle form to provide wider width in portrait mode and to provide higher height in landscape mode compromises locating character representation of keys on mass center of the keys.

### Claim 3 (depends on 1)

The method of claim 1, wherein shaping keys in a non-rectangle form to provide wider width in portrait mode and to provide higher height in landscape mode compromises locating character representation of keys at the same height along a row.

### Claim 4 (depends on 1)

The method of claim 1, wherein shaping keys in a non-rectangle form to provide wider width in portrait mode and to provide higher height in landscape mode compromises utilizing solutions for portrait mode and landscape mode independently.

### Claim 5 (depends on 1)

The method of claim 1, wherein shaping keys in a non-rectangle form to provide wider width in portrait mode and to provide higher height in landscape mode compromises utilizing solution for all keys of the soft keyboard as well as to some keys or some rows of the soft keyboard.

### Claim 6 (depends on 1)

The method of claim 1, wherein shaping keys in a non-rectangle form to provide wider width in portrait mode and to provide higher height in landscape mode compromises utilizing solution for any keyboard layout.

### Claim 7 (depends on 1)

The method of claim 1, wherein in portrait mode keys are shaped with wider width on the either bottom or top edge and narrower width on the opposite edge compromises shifting keys towards their wide edge.

### Claim 8 (depends on 1)

The method of claim 1, wherein key shapes allow to be complementarily aligned compromises shaping keys differently with flat bottom edge that are above a rectangle key or above the bottom border of device display.

### Claim 9 (depends on 1)

The method of claim 1, wherein key shapes allow to be complementarily aligned compromises shaping keys differently that have one or more absent surrounding key.

### Claim 10 (depends on 1)

The method of claim 1, wherein key shapes allow to be complementarily aligned compromises shaping keys on the top row of the keyboard differently with flat top edge.

### Claim 11 (depends on 1)

The method of claim 1, wherein key shapes allow to be complementarily aligned compromises shaping keys in the middle of a row differently to bring in vertical symmetry to the row.

### Claim 12 (depends on 1)

The method of claim 1, wherein key shapes allow to be complementarily aligned compromises shaping keys on the left and right display border differently.

### Claim 13 (depends on 1)

The method of claim 1, wherein in portrait mode keys are shaped with wider width on the either bottom or top edge and narrower width on the opposite edge; compromises utilizing larger area towards the top of device display in portrait mode comparison to soft keyboards with rectangular shaped keys.

### Claim 14 (depends on 1)

The method of claim 1, wherein key shapes allow to be complementarily aligned compromises leaving a space out by sparing a key or more and partially fill up the left over space by extending surrounding keys.

### Claim 15 (depends on 1)

The method of claim 1, wherein key shapes allow to be complementarily aligned compromises leaving a space out by sparing a key or more and fill up the left over space by extending surrounding keys.
