VSP: A Virtual Smartphone Platform to Enhance the Capability of Physical Smar...Keshav Vaswani
Abstract—Smart mobile devices have become ubiquitous, and
people prefer to choose smartphone in daily life rather than
use the traditional personal computer. However, due to the hardware capability, the performance of smartphones varies greatly and sometimes it cannot meet the demand of users. Furthermore, if the smartphone is attacked by a malicious application, the local private sensitive information will be leaked which in turn will cause huge losses. This paper proposes VSP, a Virtual Smartphone Platform. It offers a new way to enhance the capability of the physical smartphone by providing virtual smartphone (VS) deployed in the cloud. Users operate VS remotely through the thin-client of
VSP on physical smartphones, and ignore the limits of physical mobile devices. The isolation of VS in cloud platform guarantees the security between VSes and also prevents access to private sensitive information on physical devices. The evaluation indicates that average bandwidth cost with zlib is about 80 kBps and it is suitable for use in practice.

Hand Gesture Recognition System for Human-Computer Interaction with Web-Camijsrd.com
This paper represents a comparative study of exiting hand gesture recognition systems and gives the new approach for the gesture recognition which is easy cheaper and alternative of input devices like mouse with static and dynamic hand gestures, for interactive computer applications. Despite the increase in the attention of such systems there are still certain limitations in literature. Most applications require different constraints like having distinct lightning conditions, usage of a specific camera, making the user wear a multi-coloured glove or need lots of training data. The use of hand gestures provides an attractive alternative to cumbersome interface devices for human-computer interaction (HCI). This interface is simple enough to be run using an ordinary webcam and requires little training.
