摘要： A situation awareness system includes a plurality of cameras. Each camera acquires a sequence of images of a particular part of an area of interest. There is overlap between the parts so that the system can obtain depth information about objects in the area of interest. An analyzer identifies moving objects in the areas of interest, attributes of the moving objects, and events related to the moving objects. A display device displays the attributed objects and events as annotated graphic elements and alerts.

摘要： In a multicast environment in which large-scale virtual environments are lt using locales and in which data from non-neighboring locales is ignored to minimize computation and local storage, a system is provided to find or track objects and their associated locales for locales to which a user is not listening by assigning the object a beacon and broadcasting the beacon in a subspace channel, with the beacon having the multicast address of the locale in which the sought-after object resides, thus to permit an upload of data from the particular locale. Beacons are doled out parsimoniously to objects one wants to find and objects one wants other people to find to minimize processing and data storage requirements. Ignored locales are thus located using a beacon broadcast in a subspace channel which in addition to broadcasting messages about itself to the locale it is in, also broadcasts messages into a subspace channel to others about itself and the multicast address of the locale it is in. In one embodiment, subspace channel information permits accessing non-neighboring locales which would normally be ignored due to the fact that they are not neighboring. Thus the beacon system permits keeping track of all objects possessing a beacon regardless of the locales in which they reside and regardless of whether or not the locales in which they reside are being accessed, such that objects are not lost due to the ignoring of locales by the multicasting system.
摘要翻译：在使用区域设置构建大规模虚拟环境并且忽略来自非相邻区域的数据被忽略以最小化计算和本地存储的多播环境中，提供了一种系统，用于查找或跟踪对象及其相关联的区域设置，用户不通过向对象分配信标并在子空间信道中广播信标，其中信标具有所寻找的对象所在的区域的多播地址，从而允许从特定区域的数据上传。信标被轻松地放在想要查找的对象和想要其他人找到的对象上，以最小化处理和数据存储要求。因此，忽略的区域设置使用在子空间信道中的信标广播来定位，除了将自身广播到其所在的区域之外，还将消息广播到其他关于自身的子空间信道以及它所在的区域的多播地址。在一个实施例中，子空间信道信息允许访问通常被忽略的非相邻区域，因为它们不是相邻的。因此，信标系统允许跟踪拥有信标的所有对象，而不管其驻留的区域，而不管它们所驻留的区域是否被访问，使得对象不会由于忽略区域设置而丢失组播系统。

摘要： An all-audio, hands-free and eyes-free interactive tutor provides time-efficient and reduced-boredom instruction by varying a course of instruction based on the correct and incorrect responses of the user so as to frequently repeat and provide positive feedback for poorly-learned items of knowledge, to periodically refresh well-learned items and to suggest that rest be taken or to switch to easier material whenever too many human errors have occurred. The audio interactive tutor includes an audio input module, in the preferred embodiment a voice recognition unit based on a finite state grammar, an audio output module, a course of study and a user model. In a preferred embodiment, the course of study provides for human error control as well as for voice recognition unit error control, which synergistically cooperate to render the tutor substantially fault-tolerant and therewith enables the employment of commercially-available but not excessively accurate voice recognition units. The tutor may be embodied to operate on a PC or workstation, or may be embodied to operate as a stand-alone tutor. Spanish language instruction is disclosed in an exemplary embodiment.
