Actuated multi-faced keys

A keypad assembly, comprising:

• a substantially planar icon sheet, comprising:
• a first image associated with first key information, and
• a second image associated with second key information;
• an actuator to:
• support a proximal end of a first wire having a first length, the first wire to:
• displace the actuator linearly, in a first direction parallel to the plane of the icon sheet, to a first position when the first length chan as a result of a current applied to a distal end of the first wire, and
• support a proximal end of a second wire having a second length, the second wire to:
• displace the actuator linearly, parallel to the first direction, to a
• second position when the second length changes;
• and
• a lens to:
• provide the first image to a user when the actuator is in the first position, and
• provide the second image to the user when the actuator is in the second position.

A keypad assembly, comprising:

• a surface, comprising:
• a first plurality of stripes making up a first icon associated with first key information, and
• a second plurality of stripes making up a second icon associated with second key information;
• an actuator to:
• displace the surface linearly, in a first direction to a first position in response to a change in length of a first wire as a result of a current applied to the first wire, and
• displace the surface linearly, parallel to the first direction to a second position in response to a change in length of a second wire as a result of a current applied to the second wire;
• and
• a lenticular lens to:
• display the first icon to a user when the actuator is in the first position, and
• display the second icon to the user when the actuator is in the second position.

A substantially planar keypad assembly, comprising:

• a window, parallel to the plane of the keypad, to:
• display key information to a user when the key information is in the window;
• a surface, comprising:
• first key information,
• second key information, and
• third key information;
• and
• an actuator, connected to a wire, to:
• move linearly, as a result of a current applied to the wire, in a first direction substantially parallel to the window to place the first key information into the window,
• move in a second direction substantially opposite to the first direction to place the second key information into the window, and
• move in a third direction substantially parallel to the window and substantially perpendicular to the first and second directions to place the third key information into the window.

A device, comprising:

• means to render a first image associated with first key information of a substantially planar keypad or a second image associated with second key information of the substantially planar keypad to a user when an actuator is in a first position;
• means to apply a current to a wire to cause the wire to change length;
• means to displace the actuator linearly, parallel to the plane of the keypad as a result of the changed wire length;
• and
• means to change a relationship between the first image or the second image and the rendering means in response to displacing the actuator linearly, parallel to the plane of the keypad where the changed relationship causes the first image or the second image to be rendered to the user via the rendering means.
