Keyboard for hand-held devices
View Patent ↗A hand-held electronic device has a keyboard with a plurality of keys, each key having a substantially flat contact surface extending to the sides of each key. One of the sides of the key is beveled.
1. A handheld electronic device comprising:
a keyboard having a first key having a first contact surface extending between opposed first key sides, and between a first key top and a first key bottom, and having a first cross-section between one of the first key sides and the other of the first key sides in which one of the first key sides meets the first contact surface at an obtuse angle, the first contact surface and the first key side meeting the first contact surface at an obtuse angle, together, defining a user tactile target; and
a second key having a second contact surface extending between opposed second key sides, and between a second key top and a second key bottom, and having a second cross-section between one of the second key sides and the other of the second key sides in which one of the second key sides meets the second contact surface at a substantially right angle;
the first and second keys being oriented such that one of the second key sides is adjacent to one of the first key sides.
2. The handheld electronic device of claim 1 wherein the first contact surface includes a substantially planar first contact surface and a sloping planar first contact surface.
3. The handheld electronic device of claim 2 further including a housing having an upper face, the substantially planar first contact surface being substantially parallel to the upper face.
4. The handheld electronic device of claim 1 wherein the second contact surface includes a substantially planar second contact surface and a sloping planar second contact surface.
5. The handheld electronic device of claim 4 further including a housing having an upper face, the substantially planar second contact surface being substantially parallel to the upper face.
6. The handheld electronic device of claim 1 wherein the device includes a housing, the keyboard being provided on an upper face of the housing.
7. The handheld electronic device of claim 1 further including a display.
8. The handheld electronic device of claim 1 wherein the keyboard includes a plurality of first and second keys, and a midline extending along a longitudinal axis of the keyboard, wherein the first and second keys located left of the midline each include a sloping planar contact surface that slopes in a first direction and the first and second keys located right of the midline each include a sloping planar contact surface that slopes in an opposite, second direction.
9. The handheld electronic device of claim 1 , where the first contact surface and the first key side meeting the first contact surface at an obtuse angle are contacted by a user when the user presses the first key.
10. A keyboard comprising:
a keyboard having a first key having a first contact surface extending between opposed first key sides, and between a first key top and a first key bottom, and having a first cross-section between one of the first key sides and the other of the first key sides in which one of the first key sides meets the first contact surface at an obtuse angle, the first contact surface and the first key side meeting the first contact surface at an obtuse angle, together, defining a user tactile target; and
a second key having a second contact surface extending between opposed second key sides, and between a second key top and a second key bottom, and having a second cross-section between one of the second key sides and the other of the second key sides in which one of the second key sides meets the second contact surface at a substantially right angle;
the first and second keys being oriented such that one of the second key sides is adjacent to one of the first key sides.
11. The keyboard of claim 10 wherein the other of the first key sides meets the first contact surface at a substantially right angle.
12. The keyboard of claim 10 wherein the other of the second key sides meets the second contact surface at an obtuse angle.
13. The keyboard of claim 10 wherein the keyboard is provided on an upper face of an electronic device.
14. The keyboard of claim 13 wherein the electronic device further includes a display provided adjacent to the keyboard.
15. The keyboard of claim 10 wherein the first contact surface includes a substantially planar first contact surface and a sloping planar first contact surface.
16. The keyboard of claim 15 wherein the keyboard is provided in a housing having an upper face, the substantially planar first contact surface being substantially parallel to the upper face.
17. The keyboard of claim 10 wherein the second contact surface includes a substantially planar second contact surface and a sloping planar second contact surface.
18. The keyboard of claim 17 wherein the keyboard is provided in a housing having an upper face, the substantially planar second contact surface being substantially parallel to the upper face.
19. The keyboard of claim 10 wherein the keyboard includes a plurality of first and second keys, and a midline extending along a longitudinal axis of the keyboard, wherein the first and second keys located left of the midline each include a sloping planar contact surface that slopes in a first direction and the first and second keys located right of the midline each include a sloping planar contact surface that slopes in an opposite, second direction.
20. The keyboard of claim 10 , where the first contact surface and the first key side meeting the first contact surface at an obtuse angle are contacted by a user when the user presses the first key.
21. The keyboard of claim 10 , where the first contact surface and the first key side meeting the first contact surface at an obtuse angle are contacted by a user when the user presses the first key.
22. A keyboard comprising:
a plurality of first keys each having a first contact surface extending between opposed first key sides, and between a first key top and a first key bottom, and having a first cross-section between one of the first key sides and the other of the first key sides in which one of the first key sides meets the first contact surface at an obtuse angle, the first contact surface and the first key side meeting the first contact surface at an obtuse angle, together, defining a user tactile target;
a plurality of second keys each having a second contact surface extending between opposed second key sides, and between a second key top and a second key bottom, and having a second cross-section between one of the second key sides and the other of the second key sides in which one of the second key sides meets the second contact surface at a substantially right angle; and
midline extending along a longitudinal axis of the keyboard, wherein the first and second keys located left of the midline each include a sloping planar contact surface that slopes in a first direction and the first and second keys located right of the midline each include a sloping planar contact surface that slopes in an opposite, second direction;
wherein the first and second keys are oriented such that one of the second key sides is adjacent to one of the first key sides.
