Abstract
In one embodiment a light source is provided to illuminate one or more keys. Each key has at least one glyph. The color of each glyph corresponds to the light source.
Claims39
An apparatus comprising:
- first key;
- a first non-opaque glyph of a first color disposed on said first key;
- a second non-opaque glyph of a second color disposed on said first key;
- a light source oriented towards the first key, the light source capable of providing light of a third color or a fourth color, the third color being relatively closer to a complementary color to said first color than to said second color, and the fourth color being relatively closer to a complementary color to said second color than to said first color;
- and
- a light source selector to select between said third color and said fourth color to increase contrast between said first glyph and said second glyph.

A method comprising:
- providing a key wherein the key includes a first non-opaque glyph of a first color and a second non-opaque glyph of a second color;
- and
- providing a light source oriented towards the first key, the light source capable of providing light of a third color or a fourth color, the third color being relatively closer to a complementary color to said first color than to said second color, and the fourth color being relatively closer to a complementary color to said second color than to said first color;
- and
- selecting between said third color and said fourth color to increase contrast between said first glyph and said second glyph.

An apparatus comprising:
- a keyboard having a perimeter and comprising a plurality of keys at least one of the plurality of keys having a first non-opaque glyph of a first color and a second non-opaque glyph of a second color disposed thereon;
- a light source oriented towards the first key, the light source capable of providing light of a third color or a fourth color, the third color being relatively closer to a complementary color to said first color than to said second color, and the fourth color being relatively closer to a complementary color to said second color than to said first color
- a light source to provide light of a third color or a fourth color, the third color being relatively closer to a complementary color to said first color than to said second color, and the fourth color being relatively closer to a complementary color to said second color than to said first color, wherein the light source is located on or outside of the perimeter of the keyboard;
- and
- a glyph selector communicatively coupled to the light source to select between said third color and said fourth color to increase contrast between said first glyph and said second glyph.
2 more elements
An apparatus comprising:
- a first key;
- a first non-opaque region of a first color disposed on said first key;
- a second non-opaque region of a second color disposed on said first key;
- a light source oriented towards the first key, the light source capable of providing light of a third color or a fourth color the third color being relatively closer to a complementary color to said first color than to said second color, and the fourth color being relatively closer to a complementary color to said second color than to said first color;
- and
- a light source selector to select between said third color and said fourth color to increase contrast between said first region and said second region.
