Whoever you are, whether you are female or male, senior or child, whatever your nationality, your culture, your race, your age is,  it is equal for everyone to have the rights of love.

This is an interactive installation to visualize how much are the lovers into each other.

How it works/

The operating principle of our love testing is based on humidity sensor and pulse sensor. We assume when people see the person they have a feeling with, the heart will beat faster and people will start sweating especially the palm part.

We have used both sensors to test users’ heartbeat level(BPM) and humidity(sweat) level.

Design Process/


Physical Computing

In the first version of the installation, we used gloves to test the sensors.

These three variables together:

-The faster the pulse is, the more feelings the user has.

-The higher the humidity is, the more feelings the user has.

-The higher the temperature is, the more feelings the user has.


An interactive animation will display according to the sensor value of each user. For the first 40 sec, little particles will wiggle and move randomly on screen, the moving range will based on the sensor value. The higher the value, the larger the range will be. The speed will also be changing on the data collected. Here is how it looks like:

Installation Design

Two testers will stand at each side of our testing board. They won’t see each other, and they will put their hand on the same position on each side and can see each other’s hand clearly.

When they are ready, push a button to start the testing and the sensor will start work on testing numbers.

Two users will have earphones on with voice instruction and background music, and the sensors will begin testing for 40 sec and the results will come out at the end.
