Based on my previous learning from both negative and positive emotions, I divided the content into directed documentation, separately recording aspects of these two dimensions.

As a form of evidence for our daily purchases, receipts capture the moments of our lives. They are small and encountered every day, so I referenced them as the format for the recording section of my toolkit.

I set the usage cycle of the product to be 14 days. Within these 14 days, users are required to write down three things each day that made them happy, grateful, or confident. If there were any events causing negative emotions, they would note them down, rate their perceived control over the event, and document the details of the event, thoughts, and emotions.

After 14 days, users would then reflect based on the guidance provided on the instructions. All of these aspects were directly inspired by the pattern observed in my previous Autoethnography.

Moreover, I would provide users with tools to cope with negative emotions. Initially, I considered creating an acrylic board that could be placed on a desk, featuring icons representing various tools, arranged linearly based on the perceived control level. However, during a tutorial, the tutor suggested that the tools might not necessarily be linear, and individuals might use a combination of tools. Consequently, I reclassified the different tools and changed the layout to a circular format.

The guidance emphasized the freedom to use multiple tools and encouraged users to document their experiences, allowing them to identify which tools were more effective for them.

In the end, I encouraged users to create their own tools. During the previous workshop, many participants found building with LEGO blocks enjoyable and visually effective. Initially, I intended to use LEGO blocks. However, during the tutorial, the teacher suggested that there are various ways to create tools, and LEGO is just one option. Providing LEGO blocks might limit users to this particular medium. Realizing the influence of the workshop's feedback on my decisions and recognizing the limitations of creative tools, I printed the final paper prototype and conducted user testing with four individuals.
