Samsung's simultaneous video display for smartphone - US Patent Application 20170188087

BACKGROUND OF THE INVENTION 

Field of the Invention 

Apparatuses and methods consistent with the present disclosure relate to a user terminal, a method for controlling the same, and a multimedia system, and more particularly, to a user terminal capable of simultaneously viewing image contents displayed by a display device, a method for controlling the same, and a multimedia system. 

Description of the Related Art 

Currently, display devices provide various contents to users. Particularly, viewers intend to simultaneously confirm various image contents and select contents that they want to view among the confirmed image contents. 

Conventionally, there was a method for simultaneously confirming a plurality of image contents using a picture in picture (PIP) function. In this case, a viewing hindrance phenomenon that one image content hides other image contents may occur. In addition, a problem that it is difficult to simultaneously control an original image content and a PIP image content using one remote controller has occurred. 

Further, there was a method for simultaneously confirming a plurality of image contents using a plurality of display devices. For example, there was a method for confirming image contents using a television (TV) and a smart phone, respectively. In this case, the plurality of display devices do not interwork with each other, such that the plurality of display devices should be individually controlled, which is troublesome. 

Sony's VR head-mount display authentication by using a video see-through display - US Patent Application 20170186236

BACKGROUND ART 

An image display device that is mounted on the head or the face to be used for viewing an image, that is, a head-mounted display is known. The head-mounted display includes an image display unit for each of left and right eyes, for example, and may enable a user to observe a realistic image by forming an enlarged virtual image of a display image by a virtual image optical system. The head-mounted display is highly popular. If mass-produced in the future, the head-mounted display may become widespread like mobile phones, smartphones and portable game consoles, and it is conceivable that every person will own one head-mounted display. 

The head-mounted display is equipped with a high-resolution display panel of liquid crystal or an organic electro-luminescence (EL) element, for example, as a display unit for left/right eye. Also, the head-mounted display may be categorized as a transmissive type or an opaque type. 

A transmissive head-mounted display enables a wearer to observe the surrounding scene, while mounted on the head and displaying an image (for example, see Patent Document 1), and thus, the user may avoid dangers of running into obstacles and the like at the time of use outdoors or of use during walking. 

On the other hand, an opaque head-mounted display directly covers the eyes of a wearer when mounted on the head, and the sense of immersion at the time of viewing an image is increased. By enlarging and projecting a display image by using a virtual image optical system, and enabling a user to observe an enlarged virtual image with an appropriate angle of view, and also, by reproducing multichannel sound by headphones, a realistic feeling of viewing in a movie theater may be recreated (for example, see Patent Document 2). Furthermore, also with the opaque head-mounted display, there is known a video see-through method according to which a camera for capturing the front of a wearer is built in and an external image obtained by capturing is displayed, and the wearer is enabled to observe the surrounding scene through the external image (for example, see Patent Documents 3 and 4). Additionally, in contrast to video see-through, the term "optical see-through", or simply "see-through", is used for the aforementioned transmissive head-mounted display. 

Now, with information appliances such as multifunctional terminals, such as mobile phones, smartphones and tablets, and personal computers, whose users are limited to individuals or specific user groups, input of a passcode or a password, or an authentication process using biometric information or the like is generally performed at the time of start of use. 

For example, there is proposed an electronic appliance which is provided with a touch panel display of a depression amount detection type which displays a user authentication screen for an authentication required function, checks input number information indicating a plurality of different numbers input by a user on the user authentication screen against passcode information that is stored, and releases the lock on the authentication required function in the case of match (for example, see Patent Document 5). 

Also with the head-mounted display, if users are limited, such as in the case of personal use, an authentication process has to be performed at the time of start of use. 

For example, there is proposed a glass-type or head-mounted image display device which allows display of an image on a display on the condition that biometric authentication, such as iris recognition, retina recognition, face morphing (morphing) or skeleton recognition, has been performed (for example, see Patent Document 6). 

Furthermore, there is proposed a head-mounted display which performs user identification or an authentication process by detecting movement of the gaze position or gaze point of a user by using a myoelectric sensor or an electrooculogram sensor for detecting a muscle potential or an eye potential, and by using a movement pattern of movement of the gaze position or the gaze point of the user (for example, see Patent Document 7). 

Generally, with a system which is set with an authentication function, an authentication screen is displayed at the time of start of use, and a normal operation screen is not displayed until the authentication process has been performed. 

In the case of the opaque head-mounted display, both eyes of the user are covered, and the user is placed in a state of being blindfolded with no view. If a built-in camera is turned on and a captured image is in the manner of video see-through, the user regains view, and may observe the surrounding scene. However, if the authentication function is set, a video see-through image cannot be observed until the authentication process is performed, and a state of blindfold is kept. If the authentication process is disrupted by erroneous input of a password, for example, the user is placed in a dangerous state because the view becomes lost for a long time.

Planarized semiconductor interconnect topography and method for polishing a metal layer to form interconnect 

Abstract The present invention advantageously provides a substantially planarized semiconductor topography and method for making the same by forming a plurality of dummy features in a dielectric layer between a relatively wide interconnect and a series of relatively narrow interconnect. According to an embodiment, a plurality of laterally spaced dummy trenches are first etched in the dielectric layer between a relatively wide trench and a series of relatively narrow trenches. The dummy trenches, the wide trench, and the narrow trenches are filled with a conductive material, e.g., a metal. The conductive material is deposited to a level spaced above the upper surface of the dielectric layer. The surface of the conductive material is then polished to a level substantially coplanar with that of the upper surface of the dielectric layer. Advantageously, the polish rate of the conductive material above the dummy trenches and the wide and narrow trenches is substantially uniform. In this manner, dummy conductors spaced apart by dielectric protrusions are formed exclusively in the dummy trenches, and interconnect are formed exclusively in the narrow and wide trenches. The topological surface of the resulting interconnect level is substantially void of surface disparity.
