The Hugvie is like an x-rated Snuggie. The brightly colored pillow, which is shaped like Casper the Friendly Ghost, contains two vibrating motors. These motors buzz together to create a kind of heartbeat and "human-like" sensations. To activate the device, users insert their cellphone into the head of the pillow. Sensors then make the doll vibrate according to the volume and tone of the caller's voice.
