ABSTRACT:
The method and system serve to notify the user of an event through a control device. Active notification takes place even when the computer sound and screen are disabled, for example, when in a power saving mode or screen saving mode. Notification may include visual notification, audio notification, vibratory notification, or tactile notification. Tactile notification can also serve to provide a private notification system which will not alert or disturb other people in the vicinity of the user. Such tactile notification can be provided by means of a texture change in the surface of the control device. One way in which this could be done is by raising a plurality of pegs through the surface of a control device to change its texture.
