UNDERSTANDING THE PROBLEM

The project theme centered on welfare technology, and we aimed to focus on safety-enhancing solutions to create a stronger sense of security. During brainstorming, many ideas were explored, but the discussion around first aid emerged early on. To narrow the scope, we decided to concentrate specifically on life-saving first aid, with a particular emphasis on cardiopulmonary resuscitation (CPR).

Problem identification

Research question

"How can first aid knowledge be strengthened among parents with an immigrant background from Afghanistan?"

Research shows that minority-language families have less knowledge of first aid and injury prevention compared to Norwegian-speaking families. For this reason, we chose to focus on immigrant parents from Afghanistan, as the topic is relevant to this group, and we had access to Afghan users.

Data gathering

We adopted a semi-structured approach for our data collection, which included interviews with members of the target group. Additionally, we conducted expert interviews with an operating room nurse and a volunteer from the Red Cross Rescue Corps.

UNDERSTANDING THE PROBLEM

The raw data was from the data gathering was first transcribed and analyzed using open coding, followed by the development of an affinity diagram. This approach helped to identify and map the key issues related to the topic.

The focus was on first aid training rather than specific emergency situations. Findings emphasized the need for general first aid training, given the unpredictability of emergencies and the varied contexts in which first aid may be required.

Analysis

Affinity map from user research

Our findings revealed four key recurring themes: culture, training/practice, uncertainty, and the sequence of performing first aid.

Adams matkasse

In the first design iteration, we were still focused on families with an immigrant background. Board games with cards were suggested as a solution for joint first aid training. However, the idea was rejected based on feedback indicating a lack of cultural relevance for board games.

After the concluding interviews, we decided to narrow the target group to only immigrant parents, as it became challenging to involve the entire family. We developed concepts, including a first aid starter kit inspired by Adams Matkasse and a checklist to show progress.

SKETCHING SOLUTIONS

SKETCHING SOLUTIONS

Formative Testing: Feedback was gathered on the visual prototypes and initial ideas to refine the concept further.

CREATING PROTOTYPES

We improved the low-fidelity prototypes from the previous iteration by integrating light indicators to signal which step has been reached in the stable side position, along with sound signals to guide users through a specific rhythm for chest compressions. This was accomplished using an Arduino Uno, and we added two button to activate the two different modes.

Additionally, we incorporated instruction cards featuring images and descriptions of the various steps involved in the exercises.

CREATING PROTOTYPES

We conducted usability tests with our users, and they found the prototype easy to understand but noted that the buttons were difficult to press. We took their feedback into account.

Due to COVID-19, we simplified the concept, which impacted the prototyping process. Limited access to materials led to an increased use of sketches.

Summative testing

USER TESTING & EVALUATION

After the presentation of the prototypes, we received feedback to explore the use of conductive thread to create a more engaging user interface, thereby providing users with a more exciting experience than simply pressing a button.

We acquired a mannequin head and used a pillow to give users realistic resistance while performing chest compressions.

The results

CONCLUTION

The mannequin, inspired by Rescue Anne, is equipped with lights and sounds that guide users through the compression rate and breaths.

The illustrative cards show demonstrations of the exercises, along with buttons, lights, and sounds to track your progress.

Through this project I learned the value of applying an iterative approach to development. I gained experience with user-centered design, ensuring that user needs were prioritized throughout the process. I also realized the importance of effective planning, organizing, and managing group work. I developed skills in data collection and analysis, using the gathered data to inform key design decisions. Additionally, I explored Arduino technology, which helped me acquire new prototyping skills. Finally, I understood the significance of collaboration and learned how to maintain effective teamwork, even when working remotely.
