Abstract

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.

Claims

1. A method, comprising:

determining first parameters comprising a type, a content, and/or a context of a message received from a remote user to convey to a local user of a device;

generating a current in at least one coil surrounding a fixed support coupled to a magnetic element to provide dynamic force feedback by displacing the magnetic element within the fixed support, the current generating controlled by a controller;

providing the dynamic force feedback to the local user in a first direction relative to the local user depending on the type, the content or the context of the message;

harvesting energy from the at least one coil independent of generated current controlled through the controller; and

storing the harvested energy in a re-chargeable energy source.

2. The method of claim 1, in which providing the dynamic force feedback comprises tapping the local user of the device.

3. The method of claim 1, further comprising:

providing dynamic force feedback of a first amplitude when the first parameters are for a first type of received message; and

providing dynamic force feedback of a second amplitude when the first parameters are for a second type of received message, the second amplitude differing from the first amplitude.

4. The method of claim 3, in which the first type of received message is a telephone call and the second type of received message is a short message service (SMS) message.

5. The method of claim 1, further comprising:

providing dynamic force feedback of a first frequency when the first parameters are for a first type of received message; and

providing dynamic force feedback of a second frequency when the first parameters are for a second type of received message, the second frequency differing from the first frequency.

6. The method of claim 1, further comprising providing dynamic force feedback in a third direction relative to the local user based at least in part on the proximity of the device.

7. The method of claim 1, in which providing dynamic force feedback produces no audible sound.

8. The method of claim 1, further comprising increasing at least an amplitude and/or a frequency of the dynamic force feedback according to an urgency of the received message.

9. The method of claim 1, in which the device is a set top box, music player, video player, entertainment unit, navigation device, communications device, personal digital assistant (PDA), fixed location data unit, and/or a computer.

10. A method, comprising:

determining first parameters comprising a type, a content, and/or a context of a message received from a remote user to convey to a local user of a device;

generating a current in at least one coil surrounding a fixed support coupled to a magnetic element to provide dynamic force feedback by displacing the magnetic element within the fixed support, the current generating controlled by a controller;
