<p>Dynamic force feedback is provided in a device to alert a user about a message received on the device from a remote user and to convey content, context, or a type of the message. Producing dynamic force feedback may include activating a motion induction device, which accelerates and decelerates a mass to create tapping within the device. The amplitude and frequency of the tapping may be configured to produce sequences of taps to alert the user about different types, contexts, or content of received messages. Additionally, multiple motion induction devices may be included in a device to produce dynamic force feedback along multiple dimensions. Multiple dimension dynamic force feedback may be used in providing geographical directions to a user.</p> |
