Implementations of the present disclosure include actions of receiving image data of an image capturing a scene, receiving data describing one or more entities determined from the scene, the one or more entities being determined from the scene, determining one or more actions based on the one or more entities, each action being provided at least partly based on search results from searching the one or more entities, and providing instructions to display an action interface comprising one or more action elements, each action element being to induce execution of a respective action, the action interface being displayed in a viewfinder.

A gaze monitoring system comprising: an eye tracker comprising; a camera having an optical axis; a first IR source configured to illuminate a user's eyes; the first IR source located relatively near the optical axis of the camera; and at least one second IR source configured to illuminate the user's eyes, the at least one second IR source located relatively far from the camera's optical axis, in a position such that when the gaze angle is too large to get corneal reflection images of the first IR source, the image reflection of the at least one second IR source is visible by the camera, as a corneal reflection.

During control of a user interface via free-space motions of a hand or other suitable control object, switching between control modes can be facilitated by tracking the control object's movements relative to, and its contact with a “virtual touch plane or surface” (i.e., a plane, portion of a plane, and/or surface computationally defined in space, or corresponding to any physical surface).

Examples disclosed herein relate to responsive printing. An example device includes a processor, a memory device, and a printer for physical printing of a content section of an output object following a user setting and an instruction for the output object to be printed. In an example, the device may also include a microphone to detect an audio input and a camera to detect an image input. Further, in the example, the audio input detected by the microphone and the image input detected by the camera are both used by the processor executing instructions from the memory device in providing a content section of the output object, providing the user setting, and providing instructions to the printer for the content section of the output object to be printed.

Systems, devices, and methods for expanding the eyebox of a wearable heads-up display are described. A light guide with an expanded eyebox includes a light guide material, an in-coupler, an outcoupler, and a gradient refractive index (GRIN) material. The in-coupler and the out-coupler may comprise a GRIN material. An eyeglass lens with expanded eyebox includes a light guide with expanded eyebox. A wearable heads-up display includes an eyeglass lens including a light guide with an expanded eyebox.

In order to reduce a radiation dose delivered to an object or an observer, a facility for monitoring handling of the object has an optical unit configured to direct ionizing radiation onto the object and also a filter element in order to attenuate a part of the ionizing radiation. An imaging unit may detect portions of the ionizing radiation passing through the object in order to create an image of the object. A view acquisition system may acquire a viewing movement, and a control unit is configured, during a first operating mode, to control a position of the filter element as a function of the viewing movement. The control unit is configured to identify a predefined sequence of viewing movements and, as a function thereof, to switch into a second operating mode. The position of the filter element is controlled during the second operating mode as a function of an image analysis.

A system is provided for providing additional information to a user of an injection device, the system comprising an injection device, a user device and instructions for use of the injection device, the instructions for use comprising at least one tag, wherein the tag is associated with the instructions for use or with a section or a subsection of the instructions for use, wherein the memory of the user device stores instructions which, when executed by the processor, cause the user device to: scan, using a camera and/or a wireless module, the tag; identify the instructions for use or the section of the instructions for use which the tag is associated with; based on the identification, provide the user with additional information on the particular instructions for use or the particular section of the instructions for use.

A camera system for generating an eye contact image view of a person with a gaze direction that is offset from a camera position, the camera system includes a camera configured to obtain image data of the person, a processing circuitry configured to be operatively connected to the camera and configured to obtain a camera view of the person from a camera position, and generate a synthetic camera view of the person from a virtual camera position.

A wireless position tracking device, a display system, and a wearable device are provided. The wireless position tracking device includes a rigid body, point light sources, a motion sensor, and a wireless transmission module. The rigid body has an inner concave surface, a head, a connecting portion, and a tail. The connecting portion connects the head and tail. The point light sources are fixed to positions outside the inner concave surface. The motion sensor locates in the rigid body for sensing a motion thereof and generating motion information. The wireless transmission module locates in the rigid body and electrically connects the motion sensor for wirelessly transmitting the motion information to the head-mounted device. An image capturing module of the head-mounted device captures a pattern formed by the point light sources. The head-mounted device calculates a relative position of the wireless position tracking device according to the pattern and motion information.

A remote control device sends a patterned infrared signal to the display device. A display device receives the patterned infrared signal by using a plurality of infrared receivers. The display device obtains a projection pattern of the patterned infrared signal on a display screen. The display device determines a pointing position of the remote control device on the display screen based on the projection pattern. The display device displays a prompt mark in the pointing position of the display screen, where the prompt mark is used to prompt a user with the pointing position of the remote control device on the display screen.
