<p>Techniques and apparatus to provide improved visibility to user input devices, such as keys, are disclosed. In low light conditions, key legends can be difficult to distinguish. For example, often keys have legends on them to visually distinguish them from one another, but in low light conditions it can be difficult for users to visually identify the different keys. The legends can be textual and/or graphic. Hence, according to one embodiment, light from a nearby (e.g., attached) display device can be used to provide illumination to the user input devices (e.g., keys). The user input devices can be configured to include reflective optical components to enhance reflection of light and thereby improve visibility of the keys or the legends thereon.</p> |
