User Testing 

During the class User Testing session, we had our water drop installation fully set up, but we encountered several challenges when running the code. While the tilt sensors for all objects worked as expected, the videos in Processing only popped up individually. This meant that users had to place an object into its holder, then remove it before placing another object into a different holder, as this was the only way for the corresponding videos to alternate. Additionally, the holders we initially designed were simple boxes, which confused users and made the interaction less intuitive. Many were unsure how or where to place the 3D-printed objects, which disrupted the intended flow of interaction.

User testing proved to be a critical stage in improving our project. Based on the feedback and observations, my teammate and I made several adaptations to enhance the user experience:

Redesigned Holders: We replaced the simple boxes with more functional holders tailored to each 3D-printed object. We laser-cut holes into the holders to fit the shapes of the objects, making it immediately clear where each object should be placed.

Symbol Labels: We added symbols representing each object to both sides of the holders. This provided clear visual cues, helping users identify which object belonged in which holder.

Object Redesign: Instead of using a tooth, which was confusing for users, we reprinted the object as a toothbrush, making it more recognizable and intuitive.

These changes were highly effective. During subsequent testing, users were able to interact with the installation seamlessly. They could place different objects into their respective holders without requiring any verbal instructions. The videos triggered correctly, and users noticed the changes in LED lights in the water drop, associating them with the information displayed in the videos.

A surprising and delightful outcome was how much children enjoyed the project. They actively engaged with the objects and understood the concept without needing guidance. Their parents appreciated the educational aspect, noting that the installation effectively taught children about water waste in everyday activities. The success of these adaptations demonstrated the importance of iterative design and incorporating user feedback into the development process.
