    • The present invention provides a unique system and method that facilitates navigating smoothly and gracefully through any type of content viewable on portable devices. Such navigation can be performed while preserving perspective and context with respect to a larger amount of content. The navigation can be key-based such that one or more keys of a keypad can be employed to browse through, zoom in, and/or zoom out of content. In one aspect, the content can be segmented into any number of sub-sectors or segments such that each segment can correspond to a particular number key, whereby particular portions of content can be viewed in greater or less detail by pressing or tapping on the corresponding number key. Furthermore, when viewing a first portion of content, nearby content can be glanced at by pressing and holding the respective key. When the key is released, the view returns to the first portion.
    • 本发明提供了一种独特的系统和方法,其有助于通过在便携式设备上可观看的任何类型的内容平滑且优雅地导航。 可以在保持相对于更大量的内容的透视和上下文的同时执行这种导航。 导航可以是基于键的,使得可以使用键盘的一个或多个键来浏览,放大和/或缩小内容。 在一个方面,内容可以被分割成任何数量的子扇区或段,使得每个段可以对应于特定数字密钥,由此通过按压或敲击对应的内容可以更详细地观看内容的特定部分 数字键。 此外,当观看内容的第一部分时,可以通过按住相应的键来浏览附近的内容。 当钥匙释放时,视图返回到第一部分。

    • Peripheral lenses provide simulated peripheral vision on a display device. One or more peripheral lenses may be provided to generate peripheral views corresponding to portions of peripheral vision. In a first alternative, multiple viewing frustums are utilized. A first viewing frustum is utilized to define a main view of a scene and additional viewing frustums are defined for each peripheral lens. The viewing frustums of the peripheral lenses are angularly offset relative to the viewing frustum for the main view and share a boundary with the viewing frustum for the main view. In a second alternative, a reflective object is positioned within a scene to yield peripheral views of the scene. Environment mapping is employed to determine how objects in the scene are reflected off the reflective object. The reflective object may be dynamically altered to modify the resulting peripheral view.
    • 外围镜头在显示设备上提供模拟的周边视觉。 可以提供一个或多个外围透镜以产生对应于周边视觉的部分的周边视图。 在第一替代方案中,使用多个观察平截头体。 使用第一观察平截头体来定义场景的主视图,并为每个外围透镜定义附加的视锥体。 外围透镜的观察截头锥体相对于主视图的视锥体成角度地偏移,并且与主视图的观察截头体共享边界。 在第二替代方案中,反射物体位于场景内以产生场景的周边视图。 采用环境映射来确定场景中的对象如何从反射对象中反射出来。 可以动态地改变反射对象以修改所得到的外围视图。
