1. A non-transitory computer-readable medium on which is encoded processor-executable program code, the computer-readable medium comprising: program code for receiving data from at least one packet from a touch-sensitive input device, the data indicating a movement on the touch-sensitive input device;program code for determining navigation within at least one list based at least in part on the movement;program code for determining whether to output a haptic effect, the haptic effect based at least in part on the data;program code for synchronously generating and transmitting, responsive to determining to output the haptic effect, a signal configured to cause the haptic effect; andprogram code for determining, subsequent to synchronously generating and transmitting the signal, whether a battery level is low and, responsive to determining that the battery level is low, synchronously outputting a low battery haptic effect and disabling haptic effects. 2. The non-transitory computer-readable medium of claim 1, further comprising program code for computing a position offset based at least in part on the data, and wherein program code for determining navigation within at least one list comprises program code for determining navigation within at least one list based at least in part on the position offset; and wherein the haptic effect is based at least in part on the position offset. 3. The non-transitory computer-readable medium of claim 1, wherein the program code for determining navigation includes: program code for determining whether a new list has been entered based at least in part on the data;program code for generating a new list haptic effect if the data indicates that a new list has been entered; andprogram code for determining a position change within the at least one list if the data does not indicate a new list has been entered. 4. The computer-readable medium of claim 3, wherein the program code for determining the position change is configured to indicate a position change if a position delta is greater than zero. 5. The non-transitory computer-readable medium of claim 1, further comprising: program code for determining whether an event has occurred; andprogram code for generating a haptic effect if the event has occurred. 6. The non-transitory computer-readable medium of claim 5, wherein the event is one of an end-of-list has been reached event, a scroll event has occurred event, a battery state is low event, or a button effect should be played event. 7. The non-transitory computer-readable medium of claim 5, wherein the haptic effect is one of an end list effect, a scroll effect, a detent effect, a low battery effect, or a button effect. 8. A system comprising: a touch-sensitive input device;a computer-readable-medium; anda processor in communication with the touch-sensitive input device and the computer-readable medium, the processor configured to: receive data from at least one packet from the touch-sensitive input device, the data indicating a movement on the touch-sensitive input device;determine navigation within at least one list based on the movement;determine whether to output a haptic effect, the haptic effect based at least in part on the data;responsive to determining to output the haptic effect, synchronously generate and transmit a signal configured to cause the haptic effect; andsubsequent to synchronously generating and transmitting the signal, determining whether a battery level is low and, responsive to determining that the battery level is low, synchronously outputting a low battery haptic effect and disabling haptic effects. 9. The system of claim 8, wherein the processor is further configured to compute a position offset based at least in part on the data, and wherein the processor is configured to determine navigation within at least one list based at least in part on the position offset; and wherein the haptic effect is based at least in part on the position offset. 10. The system of claim 8, wherein the processor is further configured to: determine whether a new list has been entered based at least in part on the data;generate a new list effect if a new list has been entered; anddetermine a position change within the at least one list if a new list has not been entered. 11. The system of claim 8, wherein the processor is further configured to: determine whether an event has occurred; andgenerate a haptic effect if the event has occurred. 12. The system of claim 11, wherein the event is one of an end-of-list has been reached event, a battery state is low event, or a button effect should be played event. 13. The system of claim 12, wherein the haptic effect is one of an end list effect, a low battery effect, or a button effect. 14. The system of claim 8, wherein the processor is further configured to: determine whether a scroll event has occurred;generate a scroll effect if a scroll event has occurred; andgenerate a detent effect if a scroll event has not occurred. 15. The system of claim 8, wherein the haptic effect is at least one of a variable-size detent, a hot key, a rate control, a virtual button, a long list, or a breakout. 16. A method comprising: receiving data from at least one packet from a touch-sensitive input device;computing a position offset based at least in part on the data; anddetermining whether to set a haptic effect based on a battery level;responsive to determining to set a haptic effect: if the haptic effect is to be set, determining navigation within at least one list based on the position offset; anddetermining a haptic effect based on the navigation within the at least one list;setting the haptic effect;after setting the haptic effect, determining whether the battery level is low; and responsive to determining the battery level is low, outputting a low battery effect and disabling haptic effects; orresponsive to determining the battery level is not low, outputting the set haptic effect.
