During the exam period and semester break, our team conducted two usability tests for our paper prototype with two picky eaters. The insights gained from these tests were invaluable, as they highlighted some key areas that required attention and improvement.
One of the major takeaways was that the mobile component of the prototype needed to be significantly smaller, for ease of use and portability. Additionally, during one of the conversations, one user reinforced the idea of having a physical mobile component, separate from the phone. This was because notifications from the user's phone could potentially distract or disappear, making it harder to remember to use the device regularly. Having a dedicated physical component would mitigate this issue.
Another suggestion made by one of the participants was to design the device in a way that would be more closely related to the field of food that we are dealing with. This was thought to help users understand the essence of the product with fewer explanations and make it more appealing to potential users.
Based on the feedback received during the usability tests, our team decided to focus on few main areas when creating our next prototype:
1. Reducing the size of the mobile component 2. Creating a real indicator button on the mobile component, using a potentiometer, a speaker, and LEDs. This will allow users to see a visual representation of their input and hearing a mechanical sound during rotation of the potentiometer. 3. Building a database to save the data from the mobile component, so we can provide users with feedback about their progress in their process.
During the last week, we began developing the new prototype by focusing on the key highlights we had identified. Currently, we have connected the potentiometer to enable the reading of values based on rotation, while the speaker produces the mechanical sound we were aiming for during rotation. In the upcoming week, we plan to continue with creating the connection with the LED lights and synchronize the information received from the potentiometer to a database.
While we were developing our new prototype, we decided to conduct usability tests to test the size and form of giving input. In order to achieve this, we found and created multiple objects to simulate the experience. We conducted three usability tests, and the feedback was positive overall. All participants agreed that the size of the component was appropriate for daily use. However, two participants expressed their dissatisfaction with the rotation feel, stating that it did not adequately convey a sense of "coping". To address this issue, they suggested to use something you can squeeze instead.
