Torna indietro

Abstract

Certain embodiments of the invention provide a keyboard apparatus that may include an array of keys including a modifier key associated with one or more modifiable keys. Each modifiable key may include a main label and a secondary label. The secondary label may represent a function accessible by activating the modifiable key in combination with the modifier key. Further, the secondary label may include a light-reactive material visible only upon irradiation with light having a certain predefined wavelength. A light-emitting device may direct light having the predefined wavelength towards the array. A control element, however, may activate the light-emitting device only upon activation of the modifier key. In this manner, the light-emitting device may selectively illuminate the secondary label to assist a user in identifying and accessing the same.
