Abstract: A method for using cameras in an augmented reality headset is provided. The method includes receiving a signal from a sensor mounted on a headset worn by a user, the signal being indicative of a user intention for capturing an image. The method also includes identifying the user intention for capturing the image, based on a model to classify the signal from the sensor according to the user intention, selecting a first image capturing device in the headset based on a specification of the first image capturing device and the user intention for capturing the image, and capturing the image with the first image capturing device. An augmented reality headset, a memory storing instructions, and a processor to execute the instructions to cause the augmented reality headset as above are also provided.

Abstract: An electrically activated lens filter with an electro-optic portion having a radially and circumferentially symmetric electric field gradient is disclosed. More particularly, embodiments of the lens filter include an electro-optic portion having one or more conductive plugs arranged around a center region such that an electric field within the electro-optic portion varies from a maximum at an outer rim to a minimum outside of the center region. The lens filter may include a plurality of front electrodes and rear electrodes accessible in an axial direction for electrically activating front and rear transparent conductive layers, respectively.

Abstract: A portable electronic device has a device housing, and an electronic camera module in the device housing. The module has a focusing lens to focus light from a scene, an imaging sensor to receive the focused light, and an electro-optic variable aperture to allow different amounts of the light from the scene to reach the imaging sensor. The electro-optic variable aperture may include a first aperture stack placed on a transparent substrate and a second aperture stack placed on the first aperture stack. The first aperture stack defines a first aperture and the second aperture stack defines a second aperture that is larger than the first aperture. Each aperture stack includes a transparent conductive oxide layer that is common with the adjacent aperture stack. Alternatively the electro-optic variable aperture may include an aperture stack that has two transparent conductive oxide layer layers, where one layer is in the form of concentric annuli.
