The anterior face of the lens may be segregated into a peripheral zone, an inner zone circumscribed by the peripheral zone, and a central optic zone. The prism ballast portion is provided within the inner zone, which may be further subdivided into a superior portion, an intermediate portion proximate the optic zone, and an inferior portion. The ballast portion increases in thickness along a superior-inferior line parallel to a vertical meridian, and has a substantially uniform thickness perpendicular thereto.

20090024581 | SYSTEMS AND METHODS FOR COLLABORATIVE EXPLORATORY SEARCH - Described is a new framework that combines the best of both exploratory search and social search: Collaborative exploratory search. This system allows a small group of focused information seekers to search through a collection of information in concert. The system provides exploratory feedback not only based on the individual's search behavior, but on the current, active search behavior of one's fellow search allies. The assumption is that the users who have gotten together to search collaboratively have the same information need, but differing perspectives and insights as to how to best express the queries to meet that need. The collaborative exploratory search system will therefore provide tools and algorithmic support to focus, enhance, and augment searcher activities. Searchers can, by interacting with each other through system-mediated information displays, help each other find all relevant information more efficiently and effectively. | 01-22-2009 |
20090024585 | COMPONENT-BASED CONTROL SYSTEM FOR COLLABORATIVE EXPLORATORY SEARCH SYSTEMS - Described is a component-based control system involving the interface and middleware layers for collaborative exploratory search. The components include modules for multi-user input and display capabilities, and are individually configurable to allow simultaneous manipulation of multiple search parameters and algorithms. In a collaborative exploratory search, a team of people with a shared information need engage in exploratory search together. This search happens synchronously, leveraging realtime feedback in the search loop. The search team works together, finding patterns and information that each player individually might not have found, and doing so more efficiently than any single person could have. Each team member brings their own expertise and point of view to a shared problem. Distributing tasks and roles among team members leverages individual expertise and creates efficiencies of scale. Supporting the different roles and tasks involves resolving complexities in control and display; a regulatory component performs this task. | 01-22-2009 |
20090079816 | METHOD AND SYSTEM FOR MODIFYING NON-VERBAL BEHAVIOR FOR SOCIAL APPROPRIATENESS IN VIDEO CONFERENCING AND OTHER COMPUTER MEDIATED COMMUNICATIONS - A method is described for modifying behavior for social appropriateness in computer mediated communications. Data can be obtained representing the natural non-verbal behavior of a video conference participant. The cultural appropriateness of the behavior is calculated based on a cultural model and previous behavior of the session. Upon detecting that the behavior of the user is culturally inappropriate, the system can calculate an alternative behavior based on the cultural model. Based on this alternative behavior, the video output stream can be modified to be more appropriate by altering gaze and gesture of the conference participants. The output stream can be modified by using previously recorded images of the participant, by digitally synthesizing a virtual avatar display or by switching the view displayed to the remote participant. Once the user's behavior changes to be once again culturally appropriate, the modified video stream can be returned to unmodified state. | 03-26-2009 |
