    Abstract: A synchronous video communication session may be established between two devices having corresponding device profiles that are symmetrically or asymmetrically whitelisted with respect to each other. A first device located in a first environment may receive user input indicating a request to whitelist a second device located in a second environment. Whitelisting of the second device by the first device may cause a continuous live video stream to be presented on the second device. The continuous video stream may depict at least a portion of the first environment in which the first device is located. The continuous video stream may be initially at least partially obscured. Upon initiation of a video communication session between the first device and the second device, an audio stream may begin to be delivered between the devices and the video stream may no longer be obscured and a clear video image may be presented.

    Abstract: Systems and methods for timer visualization are disclosed. A device, such as a voice-controlled device, may not have means of visually displaying a timer and/or the progression of a timer. The device may send timer data to an accessory device, which may be configured to provide one or more visual indications of the timer set via the device as well as the progression of the timer. Multiple timers may be sent and differing visual indications may be displayed to show the multiple timers and/or attributes associated with the timers, such as the location of the device in an environment, the user profile associated with the setting of the timer, and/or the state of the device.

    Abstract: Motion sickness resulting from use of a virtual reality headset can be mitigated by displaying a virtual nose in the field of view of the user. Nose data can be obtained by a user selecting various options, or determined dynamically using various image analysis algorithms. Image data captured of the user's face can be data analyzed to determine aspects such as the size, shape, color, texture, and reflectivity of the user's nose. A three-dimensional nose model is generated, which is treated as an object in the virtual world and can have lighting, shadows, and textures applied accordingly. The pupillary distance can be determined from the image data and used to determine the point of view from which to render each nose portion. Changes in lighting or expression can cause the appearance of the nose to change, as well as the level of detail of the rendering.
