A communication system has head wearable devices arranged for wireless communication in an operating environment. A first head wearable device (100) has a camera (120) for capturing an environment image and a first processor (110) arranged for detecting a further head wearable device (150) based on a viewing direction of a wearer of the first head wearable device. Then the further head wearable device is identified at an operational distance based on a remotely detectable visual property and a communication session is established between the first head wearable device and the further head wearable device. The further head wearable device has a further processor (160) for establishing the communication session. Effectively the communication session is initiated based on eye contact of the wearers of the head wearable devices. Gestures of the wearers may be detected to initiate or define the communication session.

Visual assistance systems and related methods are disclosed. A visual assistance system includes a visual assistance service configured to receive and display images from a user device on an electronic display for a live assistant. The visual assistance service is also configured to transmit assistant audio from the live assistant conveying information derived by the live assistant's review of the images. A visual assistance system comprises a user device configured to capture and transmit the images to the visual assistance service. The user device is also configured to receive the assistant audio from the visual assistance service, and reproduce the assistant audio to a user of the user device. The user is registered with the visual assistance service as having at least a minimum level of visual disability. A method of operating the visual assistance system includes receiving the images from, and transmitting the assistant audio to the user device.

A camera module comprises an image sensor having a size greater than or equal to 1/3.06 inch and less than or equal to 1/2.78 inch and a lens module comprising at least five lenses disposed in sequence between an object side and an image side of the camera module. A ratio between a half-image height of the lens module and a total track length of the camera module is greater than or equal to 0.5 and less than or equal to 0.6. A field of view of the lens module is greater than or equal to 100 degrees. An aperture of the lens module is greater than or equal to F1.8 and less than or equal to F2.4. An equivalent focal length of the lens module is greater than or equal to 10 mm and less than or equal to 20 mm.

A mobile device for projecting images on a surface and for maintaining a position of the image on the surface. The device including an image rendering module to scan the surface and to modify the image based on data obtained about a three dimensional nature of the surface. The device further including an optical image stabilization to adjust an alignment of the projector based on orientation data of the device, an electronic image stabilization module to shift the image within a projection area based on the orientation data and an image-tracking module to shift the image within the projection area based on changes in a relative positions of the image and a target.

A terminal control device has a mode control module for switching an execution mode of a terminal. The terminal control device includes a main control module configured to control driving of the terminal, a receiver sensor installed in the terminal and configured to generate a voltage in response to an external force applied from the outside of the terminal, and a signal processing unit configured to analyze a voltage value generated in the receiver sensor, to process the voltage value into a signal for switching a mode of the terminal, and to transfer the mode switching signal to the main control module.

A mobile terminal and controlling method thereof are provided. The mobile terminal includes a camera, a display unit configured to display a preview image obtained by the camera, and a controller configured to detect a first command for entering a translation mode, output a GUI window for selecting at least one partial region of a text included in the preview image to the display unit in response to the detected first command, control the display unit to display a translation result of a text corresponding the GUI window on the preview image.

Embodiments relate to the field of terminals and disclose a camera switching method for a terminal, and the terminal. In those embodiments, when the terminal is installed with a plurality of cameras, automatic and dynamic switching between the cameras may be implemented based on a to-be-photographed object, thereby improving a photographing effect of the to-be-photographed object. In those embodiment, the terminal may display, in response to a first operation of enabling a photographing function by a user, a first photographing picture captured by a first camera, where the first photographing picture includes a to-be-photographed object. If the to-be-photographed object cannot be displayed completely in the first photographing picture, the terminal may switch from the first photographing picture to a second photographing picture captured by the second camera, and disabling the first camera, where an FOV of the second camera is larger than an FOV of the first camera.

A picture shooting method and an electronic device are disclosed. The method includes: starting an under-display camera when a first picture is moved to a first region, where the first region is a screen region corresponding to a position of the under-display camera. In embodiments of this application, a user can start the under-display camera by performing a simple operation of moving a picture, which is flexible and convenient.
