Abstract: A motion-based dance system including a plurality of wireless devices, said wireless devices communicably coupled to a server. The wireless devices include a motion sensor and a location sensor. A server receives from the wireless devices position and motion information and compares them to predetermine values. Those values may indicate compliance with preset location and motion information such as a dance contest and the like. Performance information may be communicated back to the wireless devices thus allowing a wirelessly coupled dance contest or other movement activity to be performed remotely or under location and distance constraints. Certain embodiments may be coupled to an award system for recognizing and rewarding dancers for the amount of participation the dancer performs.

Abstract: A system and method including a networked processor with a chat management engine operative to embed one or more context sensitive chat widgets in a web page and receive chat messages from the widgets, wherein the messages are associated with a web page context. The system may be further operable to exchange those messages among a plurality of users and determine a sentiment value for those chat messages. In some embodiments a promo engine may modify a web page in response to the sentiment value. For example and without limitation, altering the price for a product or service, adding a product or service, or removing a product or service. Dynamic demographic congregations may be formed that allow for trigger based advertising at a predetermined sentiment value, times or event. Some embodiments provide for coupling to social networks.
