1. A method, comprising:
- at a wearable device comprising a plurality of transducers that can each generate one or more waves that propagate away from the wearable device through a medium;
selecting two or more transducers of the plurality of transducers;
selecting values for characteristics of waves to be generated by the two or more transducers based, at least in part, on a known impedance of the medium; and
activating the two or more transducers, producing waves having the selected values, including transmitting the waves into a wrist of a user in a first direction, wherein the waves propagate through the user'"'"'s body away from the wrist in a second direction and constructively interfere at a target location to create a haptic stimulation on the user, and the first direction is substantially perpendicular to the second direction.

Abstract
A method of creating localized haptic stimulations on a user includes a wearable device including a plurality of transducers that can each generate one or more waves that propagate away from the wearable device through a medium. The method includes activating two or more transducers of the plurality of transducers, selecting values for characteristics of waves to be generated by the two or more transducers based at least in part on a known impedance of the medium. The method further includes generating, by the two or more transducers, waves that constructively interfere at a target location to create a haptic stimulation on a user of the wearable device, the waves having the selected values.

18. A wearable device, comprising:
-
a plurality of transducers, each transducer being configured to generate one or more waves that propagate away from the wearable device through a medium; one or more processors; and memory storing one or more programs, which when executed by the one or more processors cause the wearable device to; select two or more transducers of the plurality of transducers; select values for characteristics of waves to be generated by the two or more transducers based, at least in part, on a known impedance of the medium; and activate the two or more transducers, producing waves having the selected values, including transmitting the waves into a wrist of a user in a first direction, wherein the waves propagate through the user'"'"'s body away from the wrist in a second direction and constructively interfere at a target location to create a haptic stimulation on the user, and the first direction is substantially perpendicular to the second direction.

19. A non-transitory computer-readable storage medium storing one or more programs configured for execution by one or more processors of a wearable device having a plurality of transducers, each transducer being configured to generate one or more waves that propagate away from the wearable device through a medium, the one or more programs including instructions, which when executed by the one or more processors cause the wearable device to:
-
select two or more transducers of the plurality of transducers; select values for characteristics of waves to be generated by the two or more transducers based, at least in part, on a known impedance of the medium; and activate the two or more transducers, producing waves having the selected values, including transmitting the waves into a wrist of a user in a first direction, wherein the waves propagate through the user'"'"'s body away from the wrist in a second direction and that constructively interfere at a target location to create a haptic stimulation on the user, and the first direction is substantially perpendicular to the second direction.
