1. INTRODUCTION

1.1 About the project

Modern hand held devices such as smart phones and PDAs have become increasingly powerful in recent years. Dramatic breakthroughs in processing power along with the number of extra features included in these devices have opened the doors to a wide range of commercial possibilities. In particular, most cell phones regularly include cameras, processors comparable to PCs and internet access.  However, even with all these added abilities, there are few applications that allow much passing of the environmental information and location based services.

 As mobile devices become more like PCs, they become the part and parcel of everyone’s life. At present, checkbooks, credit cards, cameras, planners, mp3 players etc., are being used in daily life. They become inseparable from daily activities. Numerous applications are available to plan one’s daily activity. Birthday reminder, calendar event reminder are some of the examples of those applications which play vital role in daily activities. The application that falls under this category is the Event Alerter. This application has been developed for the Google Android tablet and mobile devices.

The application can able to remind about any event / task related to academic activities such as showing the view of the daily class time table of a faculty member and students. It also provides the facility of reminding about the examination schedule to the students and the examination duty schedule to the faculty members respectively. It enables the facility of daily attendance maintenance and internal mark calculation for each and every subject to the faculty The application gets the name of the event, date, time, number of times the reminder to be given (one time or multiple times) as its input.

Currently the faculties members are provided with their respective time table schedules which have to be maintained by them manually and it takes a great deal of effort to maintain the records systematically. Also it is difficult to retrieve information from the records on paper. This application speeds up the procedure and reduces the efforts of the faculty.

2. SYSTEM ANAYSIS

2.1 Existing System

At present there is no such application is available to remind to the events like time table reminder, examination schedule reminder. Similarly, there is no application available for attendance and mark list maintenance. There are applications available to remind about the functions such as birthday, anniversary day and other events. This application is entirely a new one.

2.2 Proposed System

The proposed system is more specific in nature and has the following objectives

To provide the faculty members as well as the students to keep track of the schedule of examinations, attendance and anything else to be scheduled as per time table. This application provides the facility of creating the database and it automatically keeps track of exam time table, class time table and attendance in a systematic and efficient way.

  This system provides a graphical user friendly interface which is easy and interactive for both the time table reminder and the general event reminder.

 

3. PROJECT DESCRIPTION

3.1 Module Description

Class Time Table

This module helps to store the time table of staff and students. They can access via their authenticated and authorized login ids and store their schedule of events. It helps to store the number of hours, number of days and time duration of the classes. It alerts time table details of each hour of every day by setting time and date with repeatedly or not repeatedly by which user want.

Exam Time Table

This module helps to store the time table of students. They can access via their authenticated and authorized login ids and store their schedule of events. The staff can also post the exam schedules. It helps to store the exam dates, time duration and session. It will alert exam time table details by setting time and date. The reminder can be set for every hour by using the repetition option.

Attendance System

This module helps to track the attendance of the student with date, present/absent/on-duty details stored in the database.

Mark list

This module is used to store the mark list. The staff and the students create their account in this application to login this account. Using this mark list id only the mark list can be accessed. Otherwise it cannot be accessed. This module provides the facility to store the mark details, grade, and other marks.

Alerted Settings

This module is used to set the type of alert. The types of alerts are ringing alert and vibrate alert

Usage Help

This module helps the user to understand and handle every module of the application with screen shots along with usage tips.

6. TOOLS AND TECHNOLOGIES

In this section, the tools are described and technology that is used in developing this proposed application.

 Tools: 

1. Eclipse: We used Eclipse for development because; it is a multi-language software development environment comprising a base workspace and an extensible plug-in system for customizing the environment.

2. Microsoft word: Microsoft word is used to write the report.

 B. Technologies:

  Android SDK: It includes a mobile device emulator, a virtual device emulator that runs directly on computer. With the help of this emulator we prototyped, developed and tested our application without having a physical device.

7. CONCLUSION

This application is mainly for Android-phone users and those people who are busy with their schedules. Event Alerter is an application which helps the user about the registered event reminders on the specified date/time.

 The system is supposed to implement when the user set the reminder or schedule the calendar of events,

The application provides easy and big advantage for the student and the staff community
