摘要：Natural, efficient, intelligent, and barrier-free HCI （Human-Computer Interface） will be the main developing direction of the new intelligent HCI. Building an intelligent, natural, harmonious and humanistic HCI has been the primary developing tendency of the new HCI. ＂Select one from many＂ is one of the key questions in researching and designing HCI based on gestures. On the sin- gle channel interactive condition which is based on 3D gesture operation, we build a interactive model of＂Select one from many＂. Combining this model with ＂Token＂ technology and reciprocating movement feature, we present and realize a simple efficient ＂Se- lect one from many＂ algorithm, which is used in a concrete SOR （Selection-Operation-Release） system. In the SOR system, we real- ize a real-time selection, tracking and interaction of natural gestures.

摘要：In order to solve the problem that the drivers can't find the optimal parking lot timely,a reservation based optimal parking lot recommendation model in Internet of Vehicle(IoV) environment is *** on the users oriented parking information recommendation system,the model considers subjective demands of drivers comprehensively,makes a deeply analysis of the evaluation *** recommendation model uses a phased selection method to calculate the optimal objective parking *** first stage is screening which based on the users' subjective parking demands;the second stage is processing the candidate parking lots through multiple attribute decision *** experiments show that this model can effectively solve the problems encountered in the process of finding optimal parking lot,save the driver's parking time and parking costs and also improve the overall utilization of parking facilities to ease the traffic congestion caused by vehicles parked patrol.
