Educational keyboard device

A keyboard comprising:

• a plurality of keys that include a translucent portion in a shape of a unique character and a surrounding opaque portion;
• a set key;
• a plurality of light sources disposed beneath the plurality of keys, each light source of the plurality of light sources is disposed beneath a corresponding key of the plurality of keys;
• and
• a controller communicatively coupled with the plurality of light sources, wherein the controller:
• receives input to illuminate a first subset of the plurality of light sources;
• illuminates the first subset of the plurality of light sources such that visible light is illuminated from each light source of the first subset of the plurality of light sources and the visible light passes through a corresponding first subset of keys of the plurality of keys via the translucent portions of each key of the first subset of keys resulting in a visual display of the unique characters, and a remaining subset of light sources of the plurality of light sources other than the first subset of the plurality of light sources are not illuminated such that visible light does not pass through a corresponding subset of keys and the corresponding inactive set of keys are devoid of any representation of the unique characters;
• receives input to select keys to include in the set of keys;
• and
• activates a light source of the plurality of light sources beneath a corresponding key of the plurality of keys when the set key is pressed followed by pressing the corresponding key, and wherein when the set key is pressed followed by pressing the corresponding key with the activated light source, the light source gets inactivated.

A computer keyboard comprising:

• a plurality of keys each having a translucent portion in a shape of a character and a surrounding opaque portion;
• and
• a plurality of light sources such that each of the plurality of light sources is placed underneath a corresponding key of the plurality of keys, wherein each light source of the plurality of light sources is in either an active state or an inactive state;
• wherein, in the active state, a subset of the plurality of light sources are activated such that visible light passes through the translucent portion of a corresponding subset of the plurality of keys, and wherein in the inactive state, a subset of the plurality of light sources are inactivated such that visible light does not pass through the translucent portion of a corresponding subset of the plurality of keys;
• wherein the keyboard further comprises a lock key that locks the lighting when pressed for at least three seconds and/or when a passcode or password is entered after the lock key is pressed.
