Abstract— India is one of the Countries which have introduced EVM for Parliamentary and Assembly polls successfully. But EVM is not being used in preferential voting system because of high level complexities like need for calibration of machine before every election based on number of contestants and several other constraints in recording of votes and counting. So we are designing an EVM that is useful for preferential polling in specific and that can be extended to traditional elections as well. The study begins with the users intended to use the system. There are mainly three intended users. They are Election Presiding Officer, Voters and Higher Authorities. The services they require with the system changes with each other. However the system should be designed to meet all the end user requirements. The product is a DRE model and is implemented using microcontroller P89V51RD2. The main intension of going to EVM instead of traditional ballot paper method is to get instant results. Hence a result display unit is also required for the system. This is realized using a LCD display unit.

Hence the problem statement is defined as follows:- “To design and implement a prototype for preferential Electronic Voting Machine that serves the election process in Indian Rajya Sabha and other places where preferential election is conducted with low cost of implementation and to carry out a highly effective polling process.”

Keywords-- Ballot paper, Calibration, Counting, Elimination of votes, Preferential Electronic voting machine (EVM)

I. INTRODUCTION

The purpose of this project is to design a Preferential Voting System, for eliminating ambiguities and to reduce the lapses of votes in the present system of voting by using a secret ballot paper. Here we are designing a preferential voting machine where we can carry out Rajya Sabha and state legislative council, presidential elections [1] electronically and thereby reduce the counting overhead and paper work.

We can see electronic voting system being used in the present day situations of electing the members for state assemblies, Panchayat, members of parliament and corporate‟s for urban local bodies etc which almost reduced the overheads of lapses, manual counting and other paper works[2]. In India preferential voting system is adopted according to the constitutional laws in 1950[3]. At the initial stages preference voting papers were used which were supplied by election commission of India. Later in 1990‟s by seeing Australian and American voting system, India also started the usage of ballot papers. But in the modern day the ballot paper preferential voting system has found the weak points in terms of lapses of votes and time overhead.

In order to overcome the disadvantages of ballot paper voting system, here is an effort to design a preferential electronic voting system. Ballots papers also perform well however, in terms of user satisfaction, the DRE was significantly better than the older methods. And participants were much more satisfied with their experience of voting on the DRE (Direct Recording Electronic system)[4][5].

This paper focuses on developing a preferential EVM with following features [2].

 We should be able to calibrate the machine for number of contestants.

 This product should be low budget design

 The result of the product should be instantaneous

 It should be Easy to maintain and operate.

A. Working of Preferential voting system

759 ● Nick: 15,000

● Tony: 23,000 ● Jenny: 22,000

Now nobody has gained the absolute majority, so the person with the lowest number of first Preference votes is excluded. The candidate is Nick and then based on second preferences on his ballot papers votes are distributed to either Tony or Jenny. 6,300 of the total number of people who voted for Nick gave the 2nd preference for Tony and the remaining 8,700 people gave 2nd preference to Jenny. This gives Tony a total of 29,300 and Jenny a total of 30,700.

● Tony: 23,000 + 6,300 = 29,300 ● Jenny: 22,000 + 8,700 = 30,700

Now as Jenny has 30,700 votes, which is an absolute majority, she becomes the elected member. The process could involve more than two steps shown above. If there were more than three candidates, the candidates with the lowest votes will continue to be excluded and their Preferences are transferred, or distributed, until one candidate has an absolute majority [1][3].

II. EXISTING SYSTEM OVERVIEW

Figure 1: showing a kind Ballot Sheet which is used in existing system [8]

As shown in figure 1, In the existing system of voting we give the preference to the contesting candidate by writing preference number in the box against his/her name. In this existing system it is a bit problematic for an illliterate to cast his vote and in this system lot of problems are conflicts arrise due to rejection of invalid votes because of inaccurate and improper writing, because of giving two or more preferences to same candidate, or because the voter has given 2nd or 3rd preference without giving 1st preference. In this present model counting overhead is also very high because of the involved paperwork. And voters are also found to be not very comfortable with this model of voting.

III. OBJECTIVES OF PROPOSED MODEL

A. To Enhance Ease of Voting by Reducing the Lapses of Votes

Usually in the ballot paper voting system, there are chances of loss of valuable votes due to improper marking of preferences by voters.

Ex: in traditional system if the voter puts his/her votes in between the places of two candidates by mistake, then it will be considered as a lapse and that type of votes will be discarded. The proposed system will overcome the lapses as it will be DRE model [4].

B. To Enhance Quicker Counting

Since the voting process is computerized, speed of counting the votes based on the preference is very fast. Early declaration of results was appreciated by the political parties, contestants and the polling personnel.

C. To Reduce Menace of Eliminating Invalid Votes

It will help to reduce the disputes among the contestants over the rejected votes it must be ensured that no section of the people felt handicapped by the new system.

D .To Reduce the Paperwork

The proposed system is mainly concerned with the reduction of the paper work as it will create so many problems and disputes while counting the votes and other calculations in the ballot paper voting system.

760 And a name is assigned to each candidate. Row From left to right in the Ballot Unit 1 – 2 – 3 – 4 – 5– 6 corresponds to candidate A–B–C–D–E–F respectively. And it also has a “done” button which is to be pressed by the voter after giving all the preferences, to indicate the completion his voting. So that presiding officer permits new voter to cast his votes.

A.Polling Process

First the control unit should be pressed in order for the voter to be allowed to cast his/her vote by enabling the ballot unit. This has to be done each time a new voter comes to cast their votes [6].

The voter can give preferences in ascending order that is, if the voter presses any button first time then that vote is taken as 1st preference vote and if voter presses any button for 2nd time then that vote is taken as 2nd preference and so on. Suppose if the voter comes and presses the button “C” for 1st time then his vote has 1st preference for the 3rd candidate and if he presses button number “E” for 2nd

time then his vote has 2nd preference for 5th candidate and so on. Once the polling process is completed the terminating officials terminate the poll disabling the ballot box so that no further voting is allowed. Then counting takes place and the winner is declared.

V. REQUIREMENTS

A. Hardware and Software Requirements

P89V51RD2 microcontroller, Doorbell switches, Wires & buzzers, Crystal clock input, LED‟s, LCD display Rs 232 ic, Keil Micro vision compiler flash magic software, Operating System Windows 7 or XP .

B. Functional Requirements

1. The voter should be able to cast their votes in the ascending order of the preferences.

2. The voter shall not be able to cast their vote once the polling is terminated.

3. The number of votes for the candidate should not be revealed in the middle of the polling process.

C. Non-functional Requirements

a) Performance Requirements:

1. At a time only one voter can cast his votes[2].

2. The system should be able to deliver the results quickly 3. The user can take his own time to cast his votes.

b) Security requirements:

1. The system should be able to provide security with regard of the tampering of Ballet box.

2.The ballot box should be totally inactive once the polling is terminated.

VI. DESIGN AND IMPLEMENTATION

A.Calibration

Before the start of election higher authorities must be able to calibrate the system such that the number of button‟s enabled in ballot unit must be equal to the number of people contesting.

NOTE: (Ballot units enabled must be from button 1 to n) where “n” is the number of candidates contesting.

For ex: if 4 people are contesting for elections then higher authorities need to press button “D” shown in figure “2” that is ballot number 4, Then by doing so he enable‟s first 4 ballot units A,B,C and D. and the remaining ballot units ballot unit 5 and 6 namely ballot „E and „F‟ will remain inactive.

C. Counting Process

First, all the first preference votes are counted for each candidate. If a candidate gets more than 50%+1 of the formal first preference votes then that person is declared as elected. Suppose if no candidate has an absolute majority after counting 1st preference votes, then candidate with the

fewest 1st preference votes is excluded. Excluded

[image:5.612.88.244.324.540.2]

candidates votes are then transferred to the other candidates according to the second preferences shown by voters on these ballot papers. If still no candidate has an absolute majority, again the remaining candidate with the fewest votes is excluded and these votes are transferred. This process will continue until one candidate has more than half the total votes casted so that a candidate is declared „elected‟. This type of voting system is called preferential voting and has been used in India since 1949[1][3].

Figure 5: showing flowchart for counting process

Example for counting: Let us assume that 4 people A,B,C,D are contesting for elections and after election when first preference votes were counted it was found that A,B,C,D have got 12,10,9 and 5 first preference votes respectively. So the total number of votes needed for a candidate to be declared as winner is (12+10+9+5)/2) +1= 19. Now no candidate has got the requisite number of votes, so the candidate with least number of first preference votes (that is candidate D with 5 votes) must be eliminated and then his votes must be distributed among other candidates A,B and C by observing second preference of people who had given first preference for candidate D.

Now again let us assume that four people among those five people who have given first preference for candidate D gave second preference to candidate A and one person had given second preference to candidate B, then 4 votes will be added to candidate A and one vote will be added to candidate B and recounting is done.

Result of recounting is as follows:

A=12+4=16 B=10+1=11 C=9+0=9

Even now no candidate has got required number of votes (19 votes) to be declared as winner so again candidate with least number of votes (that is candidate C ) is eliminated and his votes are distributed till a winner is found.

PRODUCT PERSPECTIVE

1) This system is New and eliminates the traditional procedure: The traditional procedure of ballot paper voting is not clearly understood by all categories of people especially in rural cooperative society election, where it has to be trained well in order to reduce the invalid votes. The proposed system can be well understood by all categories of people which make them the task much simpler.

2) Time overhead is reduced: In the traditional system, time taken while polling each preference vote in the ballot paper is much higher for an individual voter. The proposed system is concerned with the reduction of time by providing efficient and appropriate user interface.

3) It makes Election Procedure to be carried out in a simple and effective way: In the Traditional voting system calculating the Preference Votes for each candidate manually is a complex task. The proposed system will reduce the time of the polling officials to train the counting personnel, computerized and automated counting thereby makes the task much simpler and effective.

Product is designed to meet the requirements of three different end users of the system namely

1. Election Presiding Officer 2. Voters

3. Calibrating, terminating and counting personnel
