Abstract
Embodiments include an electronic control unit comprising an audio input device for receiving an audio stream from an external audio source, the audio stream being split between an audio path and a haptic path; a wireless transceiver in the haptic path for transmitting the audio stream to at least one wearable haptic device using short-range wireless communication; and a processor coupled to the transceiver and configured to calculate an amount of latency associated with transmission of the audio stream to the wearable haptic device(s), and partition the audio stream into a plurality of audio packets including a time-to-play based on the calculated latency. The control unit further includes a buffer in the audio path for inserting a time delay into the audio stream based on the calculated latency, and an audio output device in the audio path for outputting the time-delayed audio stream to an external audio listening device.
