Brief: Using the taxonomy of behaviour change techniques (BCTs) design a digital system that encourages behaviour change.
Time: 05.03.2021-11.03.2021
Last week, we generated many ideas, and we will make decisions and lo-fi prototypes this week.
Mid Presentation
Considering all the ideas we came up with, we decided to present Gabrielle’s idea, a virtual cooking food party, which was the most feasible and detailed one on mid-term review.

Dr. Paulina Bondarek and Dr. Marion Lean suggested us to use a table of what, when, how BCT is used in the process, which would be useful for further research of BCTs and design implementation. Alaistair recommended us to think about how to open the loop and involve more people. Besides, John mentioned the reason and results of card sorting research were not be articulated in the presentation, which reminded me to take care of that in the future. Some questioned us how to change behavior by joining a food party and some advised involving physical design.
Open the loop
Thinking about the feedback we got and considering the left time, our group began to think of more feasible ideas. Inspired by the Korean government’s restrictions on food recycling (Broom,2019), I started thinking from the system perspective instead of personal behavior and came up with a co-buying and co-recycling idea.

However, after discussing with my teammates, I realized it’s overcomplicated and need to involve outside partners which is hard for us to really finish. My teammates liked the food locker idea but it’s hard to make a physical model when we are working remotely. In the end, we decided to focus on the topic that “sharing” instead of “throwing away” by linking people who live nearby and deliver love by food.
Lo-fi Prototypes
As John advised make it real and test it. Under the pressure of time, our group made lo-fi prototypes based on the sharing ideas quickly and planned to test these ideas at the weekend.

Select BCTs
Synthesizing the sharing process of our design, we found some BCTs are especially useful for specific steps, for example, 3.4 social support is useful at the linking-people stage. We selected some BCTs which are related to our design from the second-week card sorting workshop and Sebastian’s co-design session. Besides, considering combining BCTs can have a stronger effect, we also added other related BCTs from the BCTT.

During the presentation, we got useful suggestions like less instrumental more personal, how to make sure people share. Besides, John and Alaistair recommended we be more rigorous about how we select and use BCTs.
This week was challenging and difficult for our group to proceed. We redirected our design direction, regenerated ideas, and faced problems of team communication and collaboration caused by disagreements, for which we set some rules to keep good collaboration for the next two weeks.
Next week, I will describe how we test and iterate the design, and how to apply BCTs into the design.
