Experiment 5 Proposal – OK to Touch!?

Project Title
OK to Touch !?

Team members
Priya Bandodkar & Manisha Laroia

OK to Touch!? is an interactive experience to make the hidden tracking technology i.e. Fingerprinting, visible to the users through interactions with everyday desk objects. The concept uses these tangible interactions in physical objects to convey how users’ private data is being tracked without their consent in the near future.

Project Description
Peering into the digital future, OK to Touch!? is an interactive experience to make the hidden tracking technology Device Fingerprinting, visible to the users, currently used for browsers and apps and soon moving to smart devices. Through simple interactions with everyday desk objects, we will record the physical touch-points IRL, tag them and project them on screen in the backdrop to create an apparent visual of digital fingerprinting data that we as users are sharing unknowingly with each interaction we make.

Physical Installation
The setup is table top display with desk objects, with a large screen or a project wall in the backdrop. As the users interact with the objects, a visual representation of the Fingerprinting data is added on the backdrop to create a visual map and indication to the users that a simple touch or click on a smart object can be tracked and be used to profile them. It is an attempt to create an awareness about the privacy concerns associated with the Internet in today’s knowledge economy.


Setup space:
4 ½  feet x 2 ½ feet table top, set along the wall. The wall serves as the projection screen or a large TV screen could be used.

Parts & Materials
Desk objects will be selected from the following list of items (subject to prototyping results): Table from the DF studio and a chair, a book, an ink stamp, iPad or mobile phone, headphones, an alarm clock, a calculator, a box. These will be either be sourced in their original form or fabricated as indicated below:

Sourced in original form Fabricated
Book Alarm clock (laser-cut wood)
iPad or mobile phone Box (laser-cut wood)

Softwares and Hardware to be used:
p5.js, Processing and Arduino, switches, digitally fabricated objects, DIY switches.

Object Interaction Sensor (Input) Output
Book with a bookmark or pen set to a page Open & close DIY switch Graphic circle or fingerprint icon projected on the wall behind or appears (fade in) on the screen behind the display with supporting fingerprinting text, and stays there the whole time. //particle.system
