How Big is Your Digital Footprint?, 2015

The BigFoot project seeks to answer the question 'How big is your digital footprint?' by illustrating, educating and ultimately increasing awareness in the usage of passive lifelogging technologies such as social media. This project builds on the hypothesis that most social media users are unaware about how ‘big’ their digital footprint is, what it exposes and what impact it might have on themselves and society as whole.

How did you get started lifelogging/analysing data?
We are mostly interested in the passive lifelogging form known as social media. This data is hosted and controlled by social media companies. We therefore are relying on the visitors of the gallery to give us access to their data for research purposes.

Why do you find lifelogging so interesting?
It creates a meaningful insight into our behaviour. Especially how behaviour that is not intentional and/or ritualised can create powerful insights into the way we interact with others and with ourselves.

How do people in your life react when they discover the extent of your lifelogging?
Our focus is on social media therefore it is not seen as a strange interaction.

What's your favourite time of day and why?
3pm because it's nicely in the middle of the day.

Do you remember the first electronic device you owned?
A baby light plug.

What do you want done with your data after you die?
Currently my data is useless therefore it can stay where it is.

Is there about yourself would you absolutely never like tracked?

What insights on your life has tracking your data revealed?
Nothing yet. However, other research projects in this space were able to extract political bias, sex, and education only by analysing the users’ Facebook likes.

What websites, magazines or other resources inspire, confound, amuse or irritate you?
The Filter Bubble and The Social Media Mind Reader.

What is your go-to piece of tech or software for lifelogging?
Social media platforms.

We're creating a speculative timeline of the possible future of lifelogging. We're asking everyone to make one prediction for a future date. What's yours? Feel free to think big!
By 2020 all interactions between humans and objects will be recorded and analysed.
