The number of smartphone users and mobile application offerings are growing rapidly. Smartphones are often expected to offer PC-like functionality, which requires powerful processors, abundant memory and long-lasting battery life. However, their hardware today is still very limited and application developers are forced to take these limitations into consideration. A number of service providers such Dropbox [1] and Zumodrive [2] provides online storage services to smartphone users in attempt to alleviate the limitations of smartphone storages. However, to the best of our knowledge, there is still no service that offers full computation resources to smartphone users. In this paper, we propose Virtual Smartphone over IP, which provides cloud computing environment specifically tailored for smartphone users. It allows users to create virtual smartphone images in the cloud and to remotely run their mobile applications in these images as they would locally. The motivation is to allow smartphone users to more easily tap into the power of the cloud and to free themselves from the limit of processing power, memory and battery life of a physical smartphone. Using our system, smartphone users can choose to install their mobile applications either locally .Table of ContentsTable of Contentsii1.Introduction11.1Purpose11.2Document Conventions11.3Intended Audience and Reading Suggestions21.4Product Scope21.5References32.Overall Description32.1Product Perspective32.2Product Functions42.3User Classes and Characteristics52.4Operating Environment52.5Design and Implementation Constraints52.6Use Case62.7Relation102.8User Documentation..102.9Assumptions and Dependencies103.External Interface Requirements113.1User Interfaces113.2Hardware Interfaces143.3Software Interfaces143.4Communications Interfaces154.System Features154.1Functional Requirements165.Other Nonfunctional Requirements175.1Performance Requirements175.2Safety Requirements175.3Software Quality Attributes17Appendix: Glossary19

Software Requirements Specification for G-Interface

Introduction the next e slide he e has to call e someone or e come near e to the ekeyboard e himself e and e search the e specific key.Purpose An issue professional presenter often run into is that they are given a large stage, an eager audience, and a podium that they must stand by for the entirety of their presentation. He has to face many problems such as to move to the nexte slide he has to calle someone ore come neare to thee keyboarde himselfe and esearch thee specific key. Not only in presentation issues occurs while a person reading e-book, research papers, Document etc. Whenever page is end he has to search the mouse or keyboard to move to the next page or slide. In these problems the common factors are Interruption while presentation and Concentration diversion while reading. It seems like a presenter must choose between accessing the information on their slides and freedom of movement while presenting and reading. But no longer.The G-interface aim is to solve these problems by providing gesture based interface to the user. It allows user to bypass mouse and keyboard in favor of hand-waving control of application. Our system is fully based on human computer interaction and gesture recognition techniques. The purpose of our project is to develop gesture based interface of Document-Reader for the students, office person, and other presenters. For this purpose we would use Leap motion sensor which sense the motion through its three IR projector and two monochromatic cameras and provide us with depth images. On the basis of recognized gestures, this application will perform Document-Reader operations as well as control the mouse.Document ConventionsThe following document conventions are given below:

1.4.1 Developers1.4.2 Project manager1.4.3 Team Members1.4.4 The Project SupervisorProduct ScopeAutomatic recognition of gestures using computer vision, gesture recognition and human computer interaction is important for many real world applications such as sign language recognition, human robot interaction and medical imaging. We are going to develop a gesture recognition application for the students, office person, and other presenters. For this purpose we would use Leap motion sensor (Leap Motion product) which sense the motion through its three infrared LEDs projector (project infrared rays) and two monochromatic cameras and provide us frames. On the basis of these frames our application will recognize gestures for document-reader common functions such as: open file, print file, close file, scrolling, zoom in/out, Page up/down, Full screen mode, and mouse movement. These features help the use to interact efficiently and easily.1.4.1 Benefits

Human effort would be reduced. The system would not be dependent on any light constraint. Easy to use. This system would be used in universities, offices, and homes as well. This system would improve time efficiency.

1.4.2 Objectives, and goals

To develop a real-time gesture recognition system that provides Gesture based interface for Document-reader. Mouse Common functions on gestures. Document reader common functions on gestures. Reduce the effort and time of operating.
