摘要： A system and method for maintaining a background model of an image sequence by processing on multiple spatial scales. These multiple spatial scales include a pixel scale, a regional scale and a frame scale. The image sequence undergoes pixel processing that determines a current background model and provides an initial pixel assignment as either a background or a foreground pixel. Region processing further refines the initial pixel assignments by considering relationships between pixels and possibly reassigning pixels. Frame processing further refines the current background model by determining whether a substantial change has occurred in the actual background and, if so, providing a more accurate background model.

摘要： An ergonomic break system and method for scheduling and improving an ergonomic break for a user from a computing device. The system and method schedule the break based on environmental information to minimize annoyance to the user. Environmental information includes the condition of the computing device (such as whether the user is typing at the keyboard or using a mouse), the condition of the environment in the immediate vicinity of the computing device (such as whether the user is on the telephone or has another person in the room with her), and the condition of the user (such as whether the user is looking at the display device or is properly stretching during the ergonomic break). The system and method also include features that improve the user's productivity during the break and improve the effectiveness and effectiveness of the break.

摘要： A system and process for automatically initiating and terminating associations between a computer input device of some type (e.g., computer mice, keyboards, trackballs, and the like) and a computer in a computing space that can have many such devices and several computers. In this way, input devices can be used to interface with any of the computers in the space. For instance, a user could move about a room filled with computers and their respective computer monitors, with a wireless mouse, and interface with the various computers using the mouse. To this end, the aforementioned association entails redirecting signals generated by a computer input device from one computing device in a computing space to another computing device in the space. The association is either initiated or terminated depending on whether sets of preconditions have been satisfied. These preconditions can be tied to any event or combination of events desired, and a set of preconditions can include any number of preconditions, even just one. In general, the preconditions will fall in two categories—namely proximity-related preconditions and nonproximity-related preconditions. Proximity-related initiating preconditions as the name implies involve a requirement that the input devices are relatively near a computer or a display device connected to the computer for an association to be initiated. Conversely, if the input device and computer are too far apart, proximity-related terminating preconditions would dictate that any association be terminated. Nonproximity-related preconditions can concern such things as ambient conditions (e.g., illumination), device states, pre-existing associations, and device incompatibility.
