Project description

Studies show the benefits of laughter in combating stress. Laughter reduces tension and stress by relaxing muscles. ” The psychology of humour does include the function of coping before the presence of fear. According to the original formulation of the EPPM, fear control processes are defined as primarily emotional processes where people respond to and cope with their fear, not to the danger. As such, humour may be considered a legitimate coping response, and thus a fear control response.” [1]  Some psychologists suggest laughing to deal with fear. Gina Barreca believes Humor addresses the same issues as fear, not to dismiss them, but to strengthen our ability to confront them and then laugh them away from the door.[2]

My 3rd experiment is an interactive installation. I intended to look at Humor and Fear from my own perspective. Only a handful of people may not have seen Edvard Munch’s Scream painting. This experiment is inspired by the scream painting of Edvard Munch. Munch wrote in his diary in January 1892: ” One evening I was walking along a path, the city was on one side and the fjord below. I felt tired and ill. I stopped and looked out over the fjord—the sun was setting, and the clouds turning blood red. I sensed a scream passing through nature; it seemed to me that I heard the scream. I painted this picture, painted the clouds as actual blood. The colour shrieked. This became The Scream.” [3]

I thought that no artwork as beautiful as the scream of Munch could represent fear. So I manipulated his painting by using my personal style in drawing. I drew Munch’s painting once again and printed it on cardboard (Figure 2-3). But this time I considered two situations: Laughter and Fear.

The colours black and white are inspired by my perception of fear, stress and darkness, as well as peace, light and brightness. I chose the footsteps to indirectly say we should change our spot (one step forward or one step backward) to reconceptualize or reevaluate our perception of fear.

I used two F.S.R sensors: one for sound and image of laughter and the other for the sound and image of fear. I mounted the sensors on the cardboard I had prepared before. I designed them like shoe pads and placed them on the floor. When you stand on the first pad (Black pad), the sensor will be activated and the screaming sound, sound waves and the scream image will be loaded on the screen. When you change your position and go one step further (White pad), laughter sound and image will be activated on the screen. (Figure 4) Unfortunately I could not find a perfect sound effect for laughter. But I will replace it with a better sound in the future.

Experiment 2

Title: Illusion




Size of group: 1

Light Sensor (1) + Servo (1) / Arduino nano / Bread board, Wires, Resistor, and …  / transparent films, and …

Project description: This is an interactive and immersive installation. The main idea of this experiment was to create an interactive design and interactive lighting. I wanted to create an optical illusion atmosphere through the interaction of people and my painting. I had to use the ultrasonic sensor. But I only had a light sensor available. So I used the light sensor (instead of the ultrasonic sensor) just for showing my idea in a limited way. When the light comes on, the servo stops working. When the light goes off, the servo starts moving one of the transparent films over the other. Using the light source behind the transparent film, an illusory atmosphere will be created on the front wall.

In terms of the principle of calm technology, I used the phrase: “Technology can communicate, but it does not need to speak.”
In my opinion, artworks such as a painting, a sculpture, or an installation do not need to speak up or do not necessarily need to be in a large format or complicated to communicate with their audience. Rather, the interaction and interrelation between an artwork and the audience should be considered.

Fabrication Process:

One of my biggest challenges in doing this experiment was my limited access to electronic equipment in London. Creating a sensitive object with a light sensor and a Servo and fabrication at home was no easy task. But sometimes simple tools can create a tremendous visual impact. One of the most important problem I encountered in my work was 1/4w Resistors. I ordered 10k ohm and 220-ohm resistors, but Creatron company sent me the wrong Resistors. As I am new to electronics, I did not know why my circuit was not working properly. By the suggestion of a friend, I used a 10k Trimmer Potentiometer instead of a resistor, and my problem was almost solved. I decided to focus on visual impact with these tools, even if I do not have suitable resistor and sensor to write the best code. All the construction of this work has been done at home and with very limited facilities. This will be a lasting memory of the COVID Pandemic period.

Experiment 1

• project title: Hello, folks!


My initial idea was to create an interactive mirror. The mirror is similar to the mirroring art in Persian architecture. But since this was my first interactive project with P5.js, I did not have much knowledge for implementing this project. So I started working. I realized that I could create this mirror using a few simple commands and a webcam. Although in the end, this project was an interactive project, and if you do not look at the code, you may think that is a body-tracking technique. But unfortunately, this project was not related to Experiment 1 and I had to look for another idea. By the way, I liked the result of this experiment. I manipulated the colors to take a little distance from the idea of the mirror. This action created interactive and abstract circles.  I will share the link of this experiment with you below:

My main interactive project is called: Hello folks!
In this experiment, you are faced with a whiteboard that you do not know what the content is inside. With the wave of your hands, the colors flow to the canvas, and finally, the OCAD University logo appears. Since this was our first experiment in the OCAD community, I decided to greet all my friends in this way. Inspired by the rectangular structure of the OCAD logo, I used rectangular dots to create visual harmony. Implicitly, each color is a symbol of an artist and designer. Moreover, these colors show a rainbow of cultural and educational diversity in OCAD.


I created another artwork with the OCAD University logo at the same time. I used the mouse interaction with the screen, the result of which you can see below. The colors appear on the screen with each click and drag.

• project description: 

The character you see below was the first character I created in the early days with P5.JS. I did not intend to use the works of others and I wanted to develop this simple and clumsy character and make it interactive. My original idea came from dancing in front of a mirror or TV. To do that, I first intended to move the character’s shoulders. but I did not succeed. I went for his eyes. In this experiment, the pupils are connected to both sides of your shoulders. As your shoulders move, so do the pupils. You should try to keep the pupils in the center of the eyes. It is very hard work. The only way to get them to their eyes is to dance in front of a screen.

• project description: 

This is a simple experiment where the eyes control the points.
If your head bends around, the circle will also move in the direction of your head. This experiment can be used in games. Where there is silence everywhere and we are not allowed to speak and the only answer is YES or NO. My friends and I used to play this game a lot as children. In this experiment, I encountered a problem such as inverting the font, which after consulting with my friend (Adit), I realized that I had set the scale command to (-1,1) and with his help, I solved this problem.
