    Abstract: A human-machine interface involves plural spatially-coherent visual presentation surfaces at least some of which are movable by a person. Plural windows or portholes into a virtual space, at least some of which are handheld and movable, are provided by using handheld and other display devices. Aspects of multi-dimensional spatiality of the moveable window (e.g., relative to another window) are determined and used to generate images. As one example, the moveable window can present a first person perspective “porthole” view into the virtual space, this porthole view changing based on aspects of the moveable window's spatiality in multi-dimensional space relative to a stationary window. A display can present an image of a virtual space, and an additional, moveable display can present an additional image of the same virtual space. Technology is used to determine aspects of the spatiality of the display devices in the physical world, and use the determined spatiality to affect the images displayed on the displays. For example, determined spatiality of the movable display relative to another display can be used to provide relative spatiality of images the two displays present to enhance the user's immersive perception. The movable display can context-switch between pointer functionality and spatial functionality depending on whether it is pointing toward a stationary display.

    Abstract translation: 人机界面涉及多个空间相干的视觉呈现表面，其中至少一些可由人移动。 通过使用手持式显示设备和其他显示设备来提供多个窗口或入口到虚拟空间中，其中至少一些是手持式和可移动的。 可移动窗口的多维空间性（例如，相对于另一窗口）的方面被确定并用于生成图像。 作为一个示例，可移动窗口可以将虚拟空间中的第一人物透视“舷窗”视图呈现，该舷窗视图基于可移动窗口相对于固定窗口的多维空间的空间性的方面而改变。 显示器可以呈现虚拟空间的图像，并且附加的可移动显示器可呈现相同虚拟空间的附加图像。 技术用于确定物理世界中显示设备的空间性的方面，并使用确定的空间来影响显示器上显示的图像。 例如，可以使用可移动显示器相对于另一显示器的确定的空间来提供两个显示器的图像的相对空间，以增强用户的沉浸感知。 可移动显示器可以根据指示器是否指向静止显示器，在指针功能和空间功能之间进行上下文切换。

    Abstract: The exemplary illustrative non-limiting technology herein enables 3D viewing on conventional 2D displays such as home television sets by tracking a person's viewpoint. Detecting a player's viewpoint movement to change the viewing of the displayed object gives the illusion that the object is physically present in three-dimensional space. Viewpoint movement detection can provide collision-related game logic benefits such as allowing a player to dodge projectiles, giving a game character an ability to “see” the player when not behind line-of-sight obstacles, and other advantages.

    Abstract: A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. A memory controller performs a wide range of memory control related functions including arbitrating between various competing resources seeking access to main memory, handling memory latency and bandwidth requirements of the resources requesting memory access, buffering writes to reduce bus turn around, refreshing main memory, and protecting main memory using programmable registers. The memory controller minimizes memory read/write switching using a “global” write queue which queues write requests from various diverse competing resources. In this fashion, multiple competing resources for memory writes are combined into one resource from which write requests are obtained. Memory coherency issues are addressed both within a single resource that has both read and write capabilities and among different resources by efficiently flushing write buffers associated with a resource.

    Abstract: A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. The graphics processor includes an embedded frame buffer for storing frame data prior to sending the frame data to an external location, such as main memory. A copy pipeline is provided which converts the data from one format to another format prior to writing the data to the external location. The conversion may be from one RGB color format to another RGB color format, from one YUV format to another YUV format, from an RGB color format to a YUV color format, or from a YUV color format to an RGB color format. The formatted data is either transferred to a display buffer, for use by the video interface, or to a texture buffer, for use as a texture by the graphics pipeline in a subsequent rendering process.
