Zusammenfassung:A user device is presented. The user device includes an interactive substrate configured to receive touch input from a user of the user device. The user device also includes a plurality of acoustic transducers, each of the plurality of acoustic transducers being configured to generate an acoustic wave along the interactive substrate in response to a control signal. The user device also includes a first circuit configured to sense a position of the touch input from the user with respect to the interactive substrate. The user device further includes a second circuit configured to generate the control signal for each of the plurality of acoustic transducers to generate a desired vibration at the position of the touch input.
