Final Project – Ocean

This Final Project offers a framework for self-discovery and an opportunity to deploy skills and knowledge gained so far on the programme to develop into interdisciplinary project.

Project brief


What should we do to reduce the generation of marine debris and deal with existing marine debris as soon as possible?


After I have a deep understanding of the current state of the ocean, I found that the problem of marine debris is one of the most difficult problems at present. According to my research, 12 billion tons of plastic waste will be accumulated by 2050. And plastic waste has caused indelible damage to marine life, and at the same time, it can also harm human bodies because of the food chain. Plastic has existed in human life for nearly a hundred years, and it has brought tremendous convenience to human society. Humans cannot stop using plastic products. However, plastic waste has become a major part of marine waste. How to solve and balance the relationship between plastic products, humans and the ocean has become the main direction of my project.


Charity organizations and young people


I want to design for the present and the future. In response to the current situation, I chose to use the APP to solve the current ocean issues, combining public welfare organizations and young people. First of all, this APP uses blockchain technology to solve the problem of public welfare transparency, which solves the user’s trust crisis in public welfare organizations. Secondly, I combined the game with public welfare to increase the interest of the product. At the same time, I want to provide direction for the future development of this project, so I combined speculative design. I assumed the scene in 2178, and tried to use speculative design to conceive and design the trash can device in the future. In the trash can are microorganisms that can convert plastic waste into nutrient solution required by the human body. I think such a device design can stimulate people to reflect and discuss the purchase, use and disposal of plastic products, and may serve as a warning to people.

This final project attempts to solve the problem of plastic waste in the ocean, and is designed based on the cleaning and recycling of plastic waste.


I divided this final project into four modules, and the whole project was designed according to the current and future.


Discover problems

I have done a lot of research on ocean issues, and finally turned my attention to the problem of ocean plastic garbage that needs to be solved urgently.


The data shows how much plastic waste produced worldwide and how much debris enters the ocean, and shows how plastic affects wildlife and human health. The information expected to accumulate 12 billion tons of plastic waste by 2050. The damage to marine life and humans is irreversible.

Research Collect

After investigation, it is found that 80% of the garbage in the ocean is plastic products, and the plastic garbage in the ocean has caused great harm to marine life, causing injury and extinction of marine life. Plastic waste will become microplastics after exposure to the sun, and microplastics have entered the human body along the food chain, and will be deposited in the body, which may cause invisible damage to the human body. At present, the treatment of marine garbage is not very perfect, and there is no way to block the production of plastic garbage from the source.

Questionnaire survey

After conducting research, I conducted user research, which can help me clarify user groups.

Data analysis

After analyzing the data, I decided to design for young people and non-profit organizations between 20 and 40 years old, focusing on popularizing marine science knowledge, the hazards of pollutants, how to reduce plastic waste and how to deal with plastic pollution.

Mood Boards

I collected the colors and pictures of the theme direction, and used mood boards to clarify the user’s visual design needs.


I defined the direction of the research and confirmed the content of PACT.

People : Non-profit organization to clean up marine debris
Young people (20-40 years old)

Activities : Willing to participate in public welfare activities
Will use smartphones to play games
Have a habit of using a smartphone

Contexts : Willing to pay attention to the removal of plastic waste when traveling
Willing to reduce the use of plastic products
Want to contribute to cleaning up marine debris

Technologies : APP + Interactive device + Derivative product

INSIGHT : Due to insufficient publicity, people think that the impact of marine debris is not large, which leads to the lack of attention to the hazards of marine debris.

Young people are often confused because they want to participate in public welfare activities to clean up marine debris, but they do not know the corresponding channels and it is difficult to generate a sense of participation, so it is difficult to obtain interaction with public welfare organizations.

Because the transparency of public welfare activities is not enough, users cannot understand the progress of public welfare activities in real time, so it is difficult to arouse the enthusiasm of users.

Charity organizations that clean up marine debris often feel helpless, because sometimes the limitations of public welfare activities cannot allow users to have a deep sense of interactive experience and participation, so it is difficult to achieve a breakthrough in cleaning up marine debris.

POV : Young people need to pay more attention to the public welfare activities of ocean cleanup, because it will affect the breakthrough of cleaning up marine debris.

Users need to know what are the hazards of marine plastic waste, because if users know that marine plastic waste harms not only marine life, but also the human body, users will reduce the disposal of plastic waste.

Non-profit organizations need to pay more attention to the sense of participation in public welfare activities, because it will affect the interaction between young people and non-profit organizations.

HMW : How might we design so that people can actively participate in the process of processing marine debris, to encourage people to help deal with marine debris, thereby speeding up the processing of marine debris.

How might we use speculative design to design the transformation and treatment of plastic waste in the future.

How mignt we design offline recycling mechanisms to encourage people to give up disposable plastic products, thereby reducing the generation of plastic waste.

Empathy Map

I use the empathy map method to help me understand the user’s feelings, emotions, thoughts and pain points throughout the experience.


I created two personas for different users. Personas can quickly identify the actual needs of users, and quickly summarize the results of user research to simplify the design.

User Experience Map

I contacted a user who had participated in clean-up ocean public welfare activities. Based on her description, I created the User Experience Map.


Define ideas and functions.

Blockchain technology

After learning that users questioned the transparency of public welfare activities, I tried to find a solution, and finally chose to use blockchain technology to solve this problem, and drew the token circulation diagram.

APP Design

User experience

Flow Chart – first draft

Define the workflow of the App.

Paper Prototype

I made a paper model to test the workflow and some functions.

During the test, I found some problems with the application.

Offline recycling is not obvious enough. If the offline recycling function is placed on the main page, it will be more convenient for users to perform offline recycling.

Daily missions are not enough to promote ocean knowledge and the current state of the ocean, so I consider adding ocean news to the daily missions, and users can get tokens after browsing. This can not only promote marine knowledge, but also allow users to understand the progress of marine garbage removal.


I used the wireframes approach to explore the logical framework of the app.、

LOGO design

App font and color selection

Game design

I did some research related to games.

Game design involves system logic and social psychology. And through the game, users can also be aware of some of the problems in the current society, which may make the world a better place.


I have added OCEAN GAME to the daily missions of the APP. Users can earn tokens through the game and use the tokens to exchange for online products or participate in offline activities.

Speculative design

Interactive device

Speculative design

Speculative design is a design that does not aim at solving problems, but allows you to discover problems. Different from problem-solving design, this is a design product full of exquisite surprises to inspire people to design and follow-up discussions on specific topics. Its essence is a kind of stimulation, not the final design itself.

Plastic waste disposal

I have investigated the current garbage disposal methods. The first four of the following five methods are currently more commonly used, and the fifth is under study.

Microbial degradation is an important way to treat plastic waste in the future, and will not cause secondary pollution to the environment, so I chose to combine the microbial degradation method with speculative design for design.


I conducted research on related projects of speculative design.

Interactive Device ideas

Plastic products have served mankind for nearly a century, and the convenience that plastic products bring to mankind is irreplaceable, so I tried to think about the following three questions:
“Can the convenience of plastic products be completely abandoned?”
“If plastic products are recycled, how will they be treated?”
“What benefits will the processed plastic products bring to humans?”

Combining the conclusions of speculative design based on the research and these three questions, I designed my project for the future.

Interactive Device design

After brainstorming, I conceived and designed the device roughly and came to the following four conclusions.

  • The most convenient way to collect plastic garbage is through the garbage bin of garbage sorting.
  • There are microorganisms in the trash can, which can decompose plastic garbage.
  • Microplastics have entered the human body and organisms along the food chain, and food safety in the future is a serious problem.
  • The products of decomposition need to become necessities of human life.

Microbial Petri Dish Design

In the future, this microorganism may be able to be used in marine ecological purification and cleaning up plastic waste.

Petri dish display

Device Sketch – 1

The selected material is inappropriate, and the sealing is not tight enough when using the material to combine the device, which will cause the liquid to flow out.
The switch setting of the device is unreasonable, and it cannot be opened well and discarded plastic garbage.
The split device is not strong enough, and there is the possibility of falling apart during use.

Device Sketch – 2

I finally chose this glass bottle as the device, first of all because it does not leak water, and it also solves the problem of switch failure. Then I proceeded to the second step and applied the microbial pigment to the bottle.

Through the test, I found that the pigment does not show the growth of microorganisms well, so I chose to use glass colored decorations instead.

Stop motion animation

In order to better display the effect of the installation, I tried to find a lot of display methods. The stop motion animation gave me a lot of inspiration, so I finally chose the stop motion animation to show the usage of the Interactive device.


After deciding how to display, I thought about storytelling.

People tend to defend their opinions.

After others have listened to your story, they will interpret it on his own and draw some “self” conclusions.

In fact, those conclusions conveyed by your carefully designed story are also what you led them to draw. When the audience hears the story and draws their own conclusions, they will believe it firmly, and will defend it on all occasions in the future.

Because people tend to defend their opinions, and this is the result of Storytelling.


I assumed the scene in 2178 and designed a trash can device for recycling plastic garbage in the future. The trash can in 2178 is full of microorganisms that can convert plastic waste into nutrient solutions needed by the human body. Humans can obtain these nutrient solutions anytime and anywhere.

Decompose plastic – 2178

poster design

Online & Offline

In order to better promote the project online and offline, I chose to use posters. Because the promotion of posters online and offline has no limitations.

AR poster

AR posters can attract the user’s attention and increase the user’s interest in the project.

After understanding the characteristics of AR posters, I conducted research.

AR poster design

When designing the poster, I imagined the ocean, which is full of plastic garbage. Humans have ways to protect themselves, but marine life does not. They can only be exposed to various garbage pollution.

Dynamic poster

I made a dynamic poster with Touchdesigner. The dynamic poster can quickly catch the viewer’s attention, so that more users can understand the project.

C4D poster

I tried to use C4D to create a three-dimensional poster as part of offline promotion. The poster on the bottom layer uses black as the background color, and the poster on the upper layer uses red as the main color, forming a visual impact. And the upper poster I added a translucent material that simulates a plastic bag to form a connection with the theme of plastic garbage.

Typography poster

The full-page font design poster produces a strong visual effect through typesetting, giving people avant-garde, bold and futuristic sense.


Typography poster design


I used posters to promote online and set up a tag called #clean.up_ocean to facilitate users to participate.
