An improved user interface and method are provided for presenting recommendations to a user when the user adds an item to a shopping cart. In response to the shopping cart add event, a page generation process generates and returns a page that includes a recommendations portion and a condensed view of the shopping cart. The recommendations portion preferably includes multiple recommendation sections, each of which displays a different respective set of recommended items selected according to a different respective recommendation or selection algorithm (e.g., recommendations based on shopping cart contents, recommendations based on purchase history, etc.). The condensed shopping cart view preferably lacks controls for editing the shopping cart, and lacks certain types of product information, making more screen real estate available for the display of the recommendations content. A link to a full shopping cart page allows the user to edit the shopping cart and view expanded product descriptions.

A host computer is provided with a main display unit and an auxiliary display unit. The host computer can free up screen space on the main display screen by routing certain types of display information to the auxiliary display unit for display. Display information can range from notification of events such as receipt of email, appointments, system messages, and information from separate applications. The auxiliary display panel may function as a user interface for audio, video, “push information”, MP3 player or become the hardware equivalent of a multimedia player. The auxiliary display panel may be integrated together with the host computer in the same physical structure or may be part of a standalone display unit that is wired or wirelessly coupled to the host computer.

Improved user interfaces and methods are provided for presenting item recommendations to a user when the user selects an item to add to an electronic shopping cart. In response to the user's selection, a page generation process generates and returns a page that includes a condensed shopping cart portion and a recommendations portion. The condensed shopping cart portion displays the contents of the shopping cart, but omits some of the item information and/or controls provided on a shopping cart page, thereby preserving more screen real estate for the display of item recommendations. The condensed shopping cart portion also includes a link to the shopping cart page.

A multi-resolution texture mapping system suitable for large scale terrain rendering using commodity graphics processing units (GPU). The GPU vertex and fragment shaders are used to implement the clip-mapping functionality. The terrain texture is represented by a combination of a mip-map and a multi-level clip-map having independent origins and off-set values. The independent clip-map levels may be independently updated. The offset values allow the origins to be associated with a reference point in a scene to be rendered. The desired clip-map level to be used to render a particular fragment may be determined using the base 2 logarithm of the maximum screen-space derivative of the source texture required by the terrain geometry to be drawn. If the desired clip-map level is non-integer and lies between two clip-map levels, appropriate texel data is created by interpolating between the bounding clip-map levels. This interpolation allows a multi-resolution texture mapping to be displayed.

A method of display with a graphical user interface includes arranging selectable navigation points along a line configured on a display screen. In some embodiments, the selectable points correspond to pieces of information to be displayed, such that selection of a selectable point causes the corresponding piece of information to be displayed. The selectable points may be arranged along the line according to a priority sequence of the corresponding pieces of information. In other embodiments, the selectable points correspond to functions useful in using an application program. Selection of a selectable point in this embodiment causes the corresponding function to be executed. The line with selectable navigation points may therefore be used in place of other display tools such as toolbars or pull-down menus, and may allow rapid selection of desired options, commands, or information while using a minimum amount of screen space.

Methods, apparatuses and systems directed, in one implementation, to a system of dynamically spawned, virtual, three-dimensional (3D) viewports which render transparently within the elements of, or on top of, an existing desktop display environment, allowing rendered objects to seamlessly interact and move between different 3-dimensional viewport spaces and the two-dimensional (2D) screen space of the desktop environment. The present invention, in one implementation, renders multiple 3-dimensional viewports and free floating 3-dimensional objects on the client desktop, seamlessly mixed into the normal event and rendering pipeline of the computing device's 2-dimensional screen aligned desktop and windowed environment.

A rapid method for calculating a local eye vector in a fixed point lighting unit. For a given triangle primitive which is to be projected into a given viewport in screen space coordinates, the local eye vector corresponds to a given eye position and a first vertex of the given triangle primitive. (A different local eye vector is calculated for each vertex of the given triangle primitive). The method first comprises generating a view vector matrix which corresponds to the given eye position and corner coordinates of the given viewport, where the corner coordinates are expressed in screen space coordinates. The view vector matrix is usable to map screen space coordinates to an eye vector space which corresponds to the given viewport. The method next includes receiving a first set of coordinates (in screen space) which correspond to the first vertex. The first set of coordinates are then scaled to a numeric range which is representable by the fixed point lighting unit. Next, the first set of coordinates are transformed using the view vector matrix, which produces a non-normalized local eye vector within the eye vector space for the given viewport. The non-normalized local eye vector is normalized to form a normalized local eye vector. The normalized local eye vector is then usable to perform subsequent lighting computations such as computation of specular reflection values for infinite light sources, producing more realistic lighting effects than if an infinite eye vector were used. These more realistic lighting effects do not come at decreased performance, however, as the local eye vector may be calculated rapidly using this method.

Methods and apparatus for diffuse indirect illumination computation using progressive interleaved irradiance sampling. Embodiments may implement a method that amortizes the cost of computing the irradiance integral for diffuse indirect illumination both temporally and spatially in screen space. For each pixel, only one secondary ray is fired. By carefully arranging different secondary ray directions for different pixels according to a sampling sequence, embodiments may filter the noisy estimate so that each pixel receives a relatively uniform coverage of the integrated hemisphere. Some embodiments may use a bilateral filter so that the geometric discontinuities are respected. The sequence may continue to a higher-level of stratification in each frame. This ensures that the rendering is converging to a noise-free result.

The present invention enables the management of arbitrary regions of a window. A surrogate window is created to contain a region of interest in a source window. A surrogate window may also be shared among multiple devices. A user may interact with the content in a source window or its surrogate window(s). A surrogate window is updated to reflect any content change in the region of interest in the source window. In the case that a user resizes a surrogate window, the entire content of the surrogate window is scaled accordingly so the entire content remains visible.

A Web browsing and visualization system and method wherein: (i) Web data is retrieved and displayed in real-time (i.e., Web data is not pre-recorded), (ii) browsing and visualization are synchronized together in the same interface, (iii) a tree-based, rings-type visualization engine, (iv) space-efficient display of visualization, and (v) the amount of resources needed from the host computer is comparatively modest. In addition, the tree-based rings engine used to create the visualization displays the information in a smaller area than previous systems. Thus, the system requires less screen space to display the same amount of information as comparable systems. Alternatively, it can display more information to the user in the same amount of screen space as comparable systems. Moreover, although the present invention is disclosed herein in connection with visualizing Web data, it can be applied to portray any information hierarchy.

The present invention provides a method and apparatus for controlling a virtual object, and a touch control device. The method comprises displaying an operation interface on the touch control device, the operation interface at least comprising a virtual touch control part corresponding to a virtual object and controlling movement of the virtual object; detecting touch control information generated by operation of the virtual touch control part by a user, the touch control information including pressing position and pressing force; and controlling the virtual object to perform corresponding turning and acceleration and deceleration operation according to the pressing position and the pressing force. Through directly integrating the acceleration and deceleration operation with the virtual touch control part controlling the movement direction of the virtual object, the turning, acceleration and deceleration operation of the virtual object can be controlled through operating the virtual touch control part, the operation is visual, rapid and convenient, an acceleration button and a deceleration button are not required to be additionally arranged, screen space is not occupied, and the operation interface is simple and concise.

One embodiment of the present invention sets forth a technique for improving graphics rendering efficiency by processing pixels in a compressed format whenever possible within a multi-sampling graphics pipeline. Each geometric primitive is rasterized into fragments, corresponding to screen space pixels covered at least partially by the geometric primitive. Fragment coverage represents the pixel area covered by the geometric primitive and determines the weighted contribution of a fragment color to the corresponding screen space pixel. Samples associated with a given fragment are called sibling samples and have the same color value. The property of sibling samples having the same color value is exploited to compress and process multiple samples, thereby reducing the size of the associated logic and the amount of data written to and read from the frame buffer.

The peripheral input and output device embeds a touch-screen display onto a mouse. Users interact with the display of the mouse using direct touch, whilst also performing regular cursor-based mouse interactions. The resulting device has many unique capabilities, in particular for interacting with auxiliary windows, such as toolbars, palettes, pop-ups and dialog-boxes. By migrating these windows onto a peripheral computer mouse challenges such as screen real-estate use and window management can be alleviated.

A system and process for replacing unwanted geometry (for example, tracking markers) in a recorded scene with new geometry. A 3-D matchmove process creates a 3-D map. The 3-D map is used to determine the 3-D coordinates of objects within the recorded scene. The 3-D coordinates of the tracking markers (and/or other objects) and the replacement portions are converted by a conversion means to 2D screen space coordinates of pixels that make up both the tracking markers (and/or other objects) and the replacement portions. A list comprising the 2D screen space pixel coordinates is then exported from the conversion means into a compositing application which reads the list of 2D pixel coordinates and makes the desired replacement automatically from frame-to-frame. Tracking markers (and/or other unwanted objects) are replaced with replacement portions with suitable characteristics.
