  • Method and apparatus for enhancing keycap legend visibility in low light conditions
    Patent number: 9007307
    Abstract: Techniques and apparatus to provide improved visibility to user input devices, such as keys, are disclosed. In low light conditions, keys 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 distinguish the different keys. The legends can be textual and/or graphic. Hence, according to one embodiment, light from a nearby display device can be used to provide illumination to the user input devices (e.g., keys). More particularly, in one embodiment, some light from the nearby display device can be directed towards and reflected from the user input devices (e.g., keys) to enhance visibility of the keys or the legends thereon.
