An augmented reality system that includes an augmented reality user device. The augmented reality user device includes display for overlaying virtual objects onto tangible objects in a real scene, a camera, and a global position system sensor. The augmented reality user device includes a processor implementing an object recognition engine, a virtual assessment engine, and a virtual overlay engine. The object recognition engine identifies features of a property. The virtual assessment engine generates a property profile based on the identified features and alternative features. The virtual assessment engine identifies the property based on the geographic location of the user. The virtual assessment engine generates a property token that includes the property profile and the location identifier. The virtual assessment engine sends the property token to a server and receives information related to the property. The virtual assessment engine presents the information as virtual objects overlaid with the real scene.

A display device is provided, which includes a controller, a display driver connected with the controller, a display panel connected with the display driver, a first barrier panel positioned above the display panel and a second barrier panel positioned above the first barrier panel. A plurality of first barriers arranged in parallel at intervals are distributed in the first barrier panel. A plurality of second barriers arranged in parallel at intervals are distributed in the second barrier panel. The controller is configured to send an image frame to the display driver. The display driver is configured to drive the display panel to display the image frame on display regions which are arranged in parallel at intervals. Each display region is configured to display a part of displayed contents in the image frame individually. The display device provides a wide-viewing-angle mode and a narrow-viewing-angle mode.

A double-sided display device includes: a first display layer, configured to implement output of a display signal of a first side; and a second display layer, configured to implement output of a display signal of a second side; a conversion layer positioned between the first display layer and the second display layer, which switches between a light-transmitting state and an opaque light-shielding state. The conversion layer is in the light-shielding state during a display phase, and in the light-transmitting state during an interfering phase which follows the display phase. During the interfering phase, the first display layer is further configured to output a first interfering signal to interfere with the image displayed by the second side, and the second display layer is further configured to output a second interfering signal to interfere with the image displayed by the first side.

A display device includes a controller, a display driver coupled to the controller, a display panel coupled to the display driver, and a lens film disposed over the display panel. The lens film includes a plurality of elongated lenses arranged in parallel with each other, each of the plurality of elongated lenses having a refractive index. The controller is configured to send an image frame to the display driver. The display driver is configured to drive the display panel to display the image frame in a plurality of display areas of the display panel arranged in parallel with each other and spaced apart from each other, each of the plurality of display areas being configured to display a portion of a display content of the image frame. The display content displayed in the plurality of display areas, after refracted by respective ones of the plurality of elongated lenses, is projected to a predetermined visible range.

A display controller includes a first register set by an open operating system, a second register set by a secure operating system, a first data input circuit configured to read normal data according to set information in the first register, a second data input circuit configured to read secure data according to set information in the second register, and a data processor configured to blend and output the normal data with the secure data to display the secure data over the normal data.

A cloud data management method, an electronic apparatus and a cloud server are proposed. The method includes: executing an application launcher installed on the electronic apparatus to send a connection establishing request to the cloud server installed with an application; receiving a finishing command from the cloud server through a connection; and loading the application into a sandbox in the electronic apparatus through the application launcher in response to the finishing command, wherein the application is not installed on the electronic apparatus.

Overlay and screen recording techniques are described that enables separate recordings of a screen and one or more overlays that were displayed on the screen during recording. In one example, pixel values of an overlay are blended with pixel values of a screen to paint the overlay onto the screen in a transparent manner that is imperceptible to the human eye but allows for original screen pixel values to be recovered from areas of the screen that were visually occluded by the overlay. This enables a user to display recording controls and visual cues on their screen without having to worry about the overlay visually occluding any screen content during the recording. One or both of the separately recorded screen and overlay streams can then be output for playback to enable viewing of the individual streams without loss in quality or content of the individual streams.

A method and a system for displaying information and content in a lock screen system having a plurality of screens so as to provide a screen lock for preventing an unintended input of a user terminal device, and a computer-readable recording medium. The method includes setting information and content on a plurality of lock screen, displaying the plurality of lock screens, providing a screen movement between the plurality of lock screens, executing an existing external application so as to provide detailed information for the information and content displayed on the plurality of lock screens, unlocking the plurality of lock screens, and posting an advertisement on a part of the plurality of lock screens. Users can easily confirm simple information and content and use the as a new medium and means for expressing themselves by setting the lock screen windows according to the personalities of the users.

An image forming apparatus 1 includes a visible image forming unit 50 that forms a visible image in the air, a screen image generation unit 102 that generates a screen image, and a controller 100 that causes the visible image forming unit 50 to generate the visible image representing the screen image generated by the screen image generation unit 102. When the visible image contains predetermined private information, the controller 100 causes the screen image generation unit 102 to generate a second screen image representing the private information and inclined by a predetermined angle with respect to a main screen of the screen image, so as to restrict a person other than an operator from viewing the private information, and causes the visible image forming unit 50 to form a visible image of the second screen image generated.

A computer system for securely controlling an insecure computer is provided. The system comprises an insecure computer, a secure computer and a unidirectional dataflow enforcer. The insecure computer comprises a dedicated video output with a hardware interface, and is configured to transmit its video output to a secure computer over a first connection and to receive instructions for controlling the insecure computer over a second connection. The secure computer is configured to receive the video output of the insecure computer over the first connection and to transmit instructions for controlling the insecure computer over the second connection. The unidirectional dataflow enforcer is configured to enforce unidirectional dataflow between the secure computer and the insecure computer, such that dataflow from the secure computer to the insecure computer over the second connection is allowed, but dataflow from the insecure computer to the secure computer over the second connection is prevented. A corresponding method is also provided.
