The electronic device may provide tactile feedback using any suitable approach, including for example vibration, heat, electrical, visual, or any other type of feedback. The electronic device may provide tactile feedback in response to detecting any particular status of the electronic device, receiving any particular input, or detecting any suitable communication received by the electronic device. For example, the electronic device may provide tactile feedback in response to identifying the current network of the device, the status of a particular electronic device component, or any other electronic device status. As another example, the electronic device may provide tactile feedback in response to receiving a particular type of communication, or in response to receiving a communication from a particular contact. As still another example, the electronic device may provide tactile feedback in response to receiving a particular user input, or to detecting a user's finger on a particular portion of the electronic device. ## Claims ### Claim 1 An electronic device, comprising: a location sensor; a tactile output device; and a processing unit configured to: determine a path between a location and a destination; compare the path to a current location obtained using the location sensor; and provide haptic output via the tactile output device as the electronic device moves along the path. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the path includes at least one direction change. ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the processing unit is configured to vary the haptic output based on a distance along the path between the electronic device and the destination. ### Claim 4 (depends on 3) The electronic device of claim 3, wherein the processing unit is configured to increase an intensity as the distance along the path increases and decrease the intensity as the distance along the path increases. ### Claim 5 (depends on 3) The electronic device of claim 3, wherein the processing unit is configured to decrease an intensity as the distance along the path increases and increase the intensity as the distance along the path increases. ### Claim 6 (depends on 3) The electronic device of claim 3, wherein the processing unit is configured to change a type of the haptic output based on the distance along the path. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the processing unit is configured to provide a different haptic output when the electronic device leaves the path. ### Claim 8 An electronic device, comprising: a location sensor; a tactile output device; and a processing unit configured to: compare a path between a location and a destination to a current location obtained using the location sensor; and provide haptic output via the tactile output device when the electronic device leaves the path. ### Claim 9 (depends on 8) The electronic device of claim 8, wherein the processing unit is configured to provide a first type of haptic output if the electronic device leaves the path in a first direction and a second type of haptic output if the electronic device leaves the path in a second direction. ### Claim 10 (depends on 9) The electronic device of claim 9, wherein the second direction leads further away from the destination than the first direction. ### Claim 11 (depends on 9) The electronic device of claim 9, wherein the second type of haptic output is stronger than the first type of haptic output. ### Claim 12 (depends on 8) The electronic device of claim 8, wherein the processing unit is configured to increase an intensity of the haptic output as the electronic device moves further from the path. ### Claim 13 (depends on 12) The electronic device of claim 12, wherein the processing unit is configured to decrease the intensity of the haptic output as the electronic device moves toward the path. ### Claim 14 (depends on 8) The electronic device of claim 8, wherein the path is not a shortest path between the location and the destination. ### Claim 15 An electronic device, comprising: a location module; a haptic device; a memory storing instructions; and a processing unit that executes the instructions stored in the memory to: determine a current location using the location module; compare the current location to a path; and provide haptic output via the haptic device to guide a user along the path. ### Claim 16 (depends on 15) The electronic device of claim 15, wherein the processing unit provides the haptic output to guide the user along the path by at least one of: providing the haptic output when the electronic device moves away from the path; or providing the haptic output while the electronic device moves along the path. ### Claim 17 (depends on 15) The electronic device of claim 15, wherein the haptic output comprises a vibration. ### Claim 18 (depends on 15) The electronic device of claim 15, wherein the haptic output comprises a temperature. ### Claim 19 (depends on 15) The electronic device of claim 15, wherein the path avoids geographic obstacles. ### Claim 20 (depends on 15) The electronic device of claim 15, wherein the path follows roads.
