Use of Virtual Interactive Techniques for personalized product design is described in this paper. Usually products are designed and built by considering general usage patterns and Prototyping is used to mimic the static or working behaviour of an actual product before manufacturing the product. The user does not have any control on the design of the product. Personalized design postpones design to a later stage. It allows for personalized selection of individual components by the user. This is implemented by displaying the individual components over a physical model constructed using Cardboard or Thermocol in the actual size and shape of the original product. The components of the equipment or product such as screen, buttons etc. are then projected using a projector connected to the computer into the physical model. Users can interact with the prototype like the original working equipment and they can select, shape, position the individual components displayed on the interaction panel using simple hand gestures. Computer Vision techniques as well as sound processing techniques are used to detect and recognize the user gestures captured using a web camera and microphone.
Most of the queries in twitter include multiuser operations. When a user login to twitter it requests the most recent tweets of whom he follows. These data may be present in different servers. The expense of these queries depends on how the data is partitioned. Existing solution for data partitioning involve hash or graph based partition. In this paper a new method for reducing the interaction between the servers are proposed. For this the data is partitioned such that most of the users that a user interacts are placed on the same partition. In addition to data partition selective replication is also implemented in the proposed approach. The data about the users that are requested most are replicated more than the other users. Experimental analysis indicates that the proposed technique provides significant improvements in the quality of the partitions, especially under low replication ratios.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
