Invitation Game: What Can Voter`s Ink Mark Do To Us?

Invitation Game: What Can Voter`s Ink Mark Do To Us?

URGENT! Please do this project before the voter mark fades away!

Recently held general election (April-May, 2019 in India) gives an opportunity to collect a massive amount of data on the growth rate of the nail, through voter`s ink mark at the fingertip. The nail bed is known to be biologically highly active. Physiological changes according to age, gender, chronic illness, etc can affect nail growth.
In this Citizen Science online project, students/teachers of schools/colleges, as well as general citizens, will be collecting, analyzing & publishing this easily accessible data through collaborative ongoing engagement.

All that we have to do is:

  • using a mobile camera take a photo of the voter`s ink-mark on the finger. (In case you have not voted, you can collect it from your friends, neighbors, relatives)
  • before taking a photo, place the finger on a graph paper, as shown in the following picture;

You can also place your finger with ink mark along the ruler/scale on a plain paper and take a photo as shown in the pictures below;

For submitting the photo/data click the link below:

Each of us will be repeating this activity of data collection with the same person twice a month.

What do we gain?

Once you collect the nail data at least two times for each month, badges like Citizen Scientist, Data Collector, and a few other badges will be granted depending on STEM habits.

You can access your data from the links below in tabular and as a gallery.

Give comments/queries if any, by clicking “Reply” icon below.

(*Note: If you are not in Voting age, you can put any household ink mark, e.g: mehandi, nail paint, etc to perform this activity)

Welcome to COOOL STEM Games and please join the discussion on the project!

In the next part of the project we will measure the growth.

May I suggest: Probably a short video can be useful. People often may get confused on the smaller marking of the graphs and measuring at the initial stage.

This activity is not about measuring. This is invitation activity therefore its simple.
They just have to keep finger on graph paper and take photo.

If they get queries, they can engage by asking questions and asking for help, it will make them active participants.

Recently held general election (April-May, 2019 in India) gives an opportunity to collect massive amount of data on the growth rate of nail, through voter`s ink mark at the fingertip.

This data can be used by participants to study how various physiological changes due to age, gender, chronic illness, etc affect growth of nail.

We are having form to fill age, gender, etc. Participants are not supposed to add those details in photo.
Each once data will be accessible to them.

This practice will mess up the data collection. Also I think it is a practice/habit that we need to develop among citizens to annotate each photo and send.

Let me understand what the suggestion is? Are you suggesting that the photograph should also have some measurement?

No. please check the link:

We want data separate from photo so that it can be easily analysed without looking at each photo.

data will be collected and publicly accessible to this link. Making changes in photos will spoil the quality of photos, and they will be confused how to use technology to edit photos.
Point is activity should be as simple as possible so that we have large number of people participating in it.

Photo is just for reference for engagement, data is most important, which they can use further inorder to make spreadsheets and publish.

Yes exactly…the photo that’s is to be sent by the people can have the legends as well

The form does ask for all the data.

There are two types of problem we were facing that in many nail growth pictures we got from various part of the country was without any reference scale behind the image it was sometime only the nail picture with white picture as background so what to do with that pictures?

Another thing is in the CUBE we were introduced to how to measure the growth of nail using image meter so if anyone want to know I can write how to use image meter foe the measurement of nail growth

@bivasnag as given in this activity , you can use graph paper behind finger nail or ruler/scale besides finger nail and click the picture.
This activity only asks to send these photos.

Please submit photo of your nail ink mark in this format.

Measurement is next activity. Link of imagemeter is given in next activity, and app has examples how to use it to measure distance.

If you get any query on measurement ,you can write about it in next activity.

Please write lucidly how one can measure the growth of nail from these photos. Give examples…
And what is your Long term objective?


@bivasnag @Hrushikesh @rahil.bhai_007 @Arunan
All you need to do is, select a double headed arrow line in imagemeter app, place that arrow from point starting to ending point you want to measure. Once you draw the line , you get the reading of measurement of that length.

This is how you can measure distance between any two points using imagemeter.

Please click the link below to get steps of measuring length using imagemeter:

@magpie please visit the link of form in activity, it records all the details.

Picture is just for reference. It need not come with data. Data is essential for further analysis and finding any patterns.

Don’t you think we should make this introduction more user friendly? @jaikishan
Let’s give one simple example of nail mark photo with a ruler along side the finger…
What you say? Rest of the explanation too can be made simpler and straight…


I agree with @meena74 Look, where are we now with nail data collection today?
Let’s review and take immediate necessary action!
Such a great opportunity! We should not loose it!


The activity is made most simpler by revewing by us before releasing.
Steps of nail mark with ruler are already mentioned in activity.

‘You can also place your finger with ink mark along the ruler/scale on a plain paper and take a photo’

Many of people have been sending on nail mark pictures on whatsapp, if we can drive and engage them to document here the same then recording and archiving can be achieved here.

We can’t blame citizen in a Citizen Science program. Our program requires to become a. attractive b. people friendly.
We can’t drive away people from other sectors, howsoever you hate whatsapp.
Make it as user friendly as whatsapp. People will gladly come!
I am with People!

Had forfeited the confidence of the government
And could win it back only
By redoubled efforts. Would it not be easier
In that case for the government
To dissolve the people
And elect another?”. - Bethold Brecht
