One variation of a method for video conferencing includes, during a setup period: accessing a test video feed; and generating a face model, representing facial characteristics of a first user depicted in the test video feed, based on features detected in the test video feed. The method also includes, during an operating period: accessing a video feed; representing constellations of facial landmarks, detected in frames in the video feed, in a feed of facial landmark containers; representing sets of facial muscle actions, detected in frames in the video feed, in a feed of facial expression containers; and transforming the feed of facial landmark containers, the feed of facial expression containers, and the face model into a feed of synthetic face images according to the synthetic face generator.

An ultrasonic humidifier may include a water tank, an atomizer arranged in the water tank, an upper cover detachably connected with the water tank and an artificial flower, wherein the upper cover is provided with a mist outlet pipeline, and a branch of the artificial flower is inserted from the mist outlet pipeline; and a user can change different varieties and styles of artificial flowers according to current mood. Different colors and styles of artificial flowers have different impacts on visual sense every time, which is not easy to generate visual fatigue. Moreover, mist is directly sprayed from the branch of the artificial flower, and the artificial flower becomes beautiful and elegant visually. When aromatic oil matched with the artificial flower is added into water, smell sense and visual sense of the user are capable of being perfectly unified.

A humidifier includes a water tank for containing a predetermined amount of water, a supporting base having a water chamber, a mist discharging channel, a mist generating module for generating a mist from the water in the water chamber and generating an air flow, and a noise reduction air duct. The noise reduction air duct has an air inlet extended from the water chamber for receiving the air flow and the mist, an air outlet extended to the mist discharging channel, and a detouring channel extended between the air inlet and the air outlet for detouring a direction of the mist from the water chamber to the mist discharging channel so as to reduce a speed of the mist for noise reduction.

The invention discloses an automatic drip feeder and a purification and aroma humidifier using the same for adding essential oil to solve the problem that existing humidifiers have a good aromatic effect in the early stage of usage, while the aromatic effect disappears in the middle and later stages. A water trough of a humidifier body is provided with a receiving groove used for receiving the automatic drip feeder. Essential oil or aromatic liquid is contained in a container of the automatic drip feeder and is quantitatively added into the water trough of the humidifier via a feed port, thus, realizing a continuous purification and aroma effect.
