Methods and systems for presenting a user interface that includes a virtual keyboard are provided. More particularly, a virtual keyboard can be presented using one or more touch screens included in a multiple display device. The content of the virtual keyboard can be controlled in response to user input. Configurable portions of the virtual keyboard include selectable rows of virtual keys. In addition, whether selectable rows of virtual keys and/or a suggestion bar is displayed together with the standard character and control keys of the virtual keyboard can be determined in response to context or user input.

Methods and devices for receiving input and presenting a user interface with two screens and an off screen gesture area. The device may have an off screen gesture area that accepts user input outside the display area. The interface inputs received in the off screen gesture are may have special handling and cause different display changes. Further, the device, having two screens, may receive user interface inputs that cross the seam between the two displays. To provide a display that acts like a single display area, the device can predict motions may cross the seam and then interrelate separate inputs on separate screens. The interrelated inputs can cause display changes as if the inputs were received as a single user interaction.

A device includes two touch sensitive displays. Particular display device (e.g., balloons, pop-up windows, tooltips, etc.) can be displayed in the two touch sensitive displays. However, in some circumstances, presenting the display device may cause problems interfacing with or viewing data on the device. Thus, the device can determine if presenting the display device in a proposed location will cause difficulties for the user. If such difficulties are predicted, the device may move the display of the display device to the other touch sensitive display.

In some embodiments, a head-mounted, near-eye display system comprises a stack of waveguides having integral spacers separating the waveguides. The waveguides may each include diffractive optical elements that are formed simultaneously with the spacers by imprinting. The spacers are disposed on one major surface of each of the waveguides and indentations are provided on an opposite major surface of each of the waveguides. The indentations are sized and positioned to align with the spacers, thereby forming a self-aligned stack of waveguides. Tops of the spacers may be provided with light scattering features, anti-reflective coatings, and/or light absorbing adhesive to prevent light leakage between the waveguides. As seen in a top-down view, the spacers may be elongated along the same axis as the diffractive optical elements. The waveguides may include structures (e.g., layers of light absorbing materials, rough surfaces, light out-coupling optical elements, and/or light trapping microstructures) along their edges to mitigate reflections and improve the display contrast.

A handheld communication device includes first and second screen assemblies, each including a screen having an active display area and housing having a rear surface, and a side surface extending between a periphery of the screen and the rear surface of the housing and a hinge connected to the first and second screen assemblies, whereby the hinge has a range of motion of more than 180 degrees.

Methods and devices for selecting a card from an application stack, wherein the card represents a corresponding application that a user would like to make active or bring focus to. The selecting includes one or more of a dragging and a tapping action, with these actions being triggers for transitioning the device to an optional drag state or tapped state, respectively. Transitioning through this state executes the activating of a corresponding application or other action on the device to facilitate window/application/desktop management. The selecting further allows a user to specify which a touch screen (or portion hereof) on which a particular application should be launched.

Methods and devices for selectively presenting a user interface in a dual screen device. More particularly, the method includes providing a gallery for the dual screen device. The gallery can present one or more images in a user interface. The gallery user interface can adapt to changes in the device configuration. Further, the gallery can display images or videos in the various configurations.

A production method for an optical waveguide including: a first step of inserting a needle-like portion at a tip end of an ejection unit into uncured cladding; a second step of moving the needle-like portion in the uncured cladding while ejecting an uncured material from the needle-like portion to form an uncured core surrounded and covered with the uncured cladding; a third step of removing the needle-like portion from the uncured cladding; and a fourth step of curing the uncured cladding and core, wherein the uncured cladding is composed of a composition including a reactive silicone compound composed of a polycondensate of a diarylsilicic acid compound of Formula [1]
