Abstract: Devices, systems, and methods for reproducing or simulating a heartbeat pattern in accordance with aspects of the present disclosure. In particular aspects, a device is configured to reproduce a tactile, auditory, and/or visual output representing a heartbeat pattern of a loved one. A user may perceive, during operation, the reproduced heartbeat pattern reproduced by the device. For example, the user may touch the device (e.g., may wrap a hand around the device, may pressed the device against any part of the user's body, etc.), the device may be activated (e.g., by the user's touch) and may reproduce an output (e.g., tactile, auditory, and/or visual) causing the user to perceive the heartbeat pattern. The heartbeat pattern may be one stored in the device, an external device and provided to the device via a link, or generated by the device dynamically during operation.
