First aid saves lives.

Picture this: you are enjoying a coffee at your local café, and the man sitting at the table next to you suddenly becomes unconscious. What do you do? Panic, right? You’re not a medical professional, but now this man’s life depends on you. You might think back to the last First Aid course you attended a few years ago, and remember to check if he’s breathing or not – but what next? How do you save this man’s life?


That is a totally normal way to react to that situation. People feel overwhelmed and are scared of doing something wrong that might exacerbate the situation. So they freeze and do nothing, simply waiting for the ambulance to finally arrive. When in reality, waiting is the biggest mistake you can make. Our brains start to die after 3-5 minutes when they are starved of oxygen. But the average response time of an ambulance is 8 minutes. In Germany, less than 50% of people performed CPR on casualties who weren’t breathing. Up to 10 000 lives could be saved each year if there were 10-20% more people who gave CPR before the ambulance arrived.

Let's change that. Let's be part of the 10-20% and save lives. 


It's time to meet Aimie.


Aimie is a voice assistant who leads you through all of the critical steps when responding to a medical emergency. She uses Artificial Intelligence to ensure that the correct reactions are taken in every situation. She listens for you to tell her when you have moved on to the next step. If you can’t speak due to exertion or if Aimie doesn’t recognize your voice under stress, you may proceed through the steps manually. Aimie is compatible with all electronic devices, but she is also able to connect to other people's devices. The ambulance is alerted to your location and is able to find you right away. At the same time, Aimie tells you how long before the ambulance will arrive on scene. She records your reactions to allow for playback to help the doctors after the patient has been turned over to medical professionals. 


There are 2 different kinds of modes: one for emergencies and one for training. The latter tests your knowledge of First Aid and allows you to improve your skills. You can save any questions that you have difficulty with and practice scenarios you are unfamiliar with. You also have the option of simply reading up on First Aid and any legal implications associated with assisting someone in an emergency. The training feature is designed to decrease the likelihood of becoming a bystander when faced with a medical emergency and educate the user on what their legal boundaries are.

In Progress


The inspiration for my thesis project came from a story I heard about a student who fell unconscious during gym class. His teacher called the ambulance, but otherwise performed no First Aid. As a result, today the student is 100% disabled. My immediate reaction was anger and an inclination to blame the teacher for their inaction, but I felt like a hypocrite doing so – my first and only First Aid course was years ago, and I didn’t feel confident about how I would handle that situation.


So I started to research the problem. What’s the typical reaction when an average person is faced with a medical emergency?

I read a lot, created an online questionnaire, interviewed First Aid responders and medical experts. Surprisingly, the overwhelming answer was fear. People are scared of doing the wrong thing or making things worse. Some even black out due to stress. Some just don’t have the knowledge of what to do. Not only the medical response, but the legal rights of a first responder as well. 


This problem gnawed at me, and I wanted to solve it. People’s lives were being lost and most of the time some immediate First Aid would have prevented it! So my solution is Aimie. She leads you through the steps verbally. You don’t have to watch or read any information, which allows you to focus on your task. You just need to listen, and you’ll need the use of both of your hands. Aimie knows what to do – let her show you. 




Aimie’s logo is the focus of the app and therefore is visible as much as possible. Voice user interfaces work differently than graphic interfaces and this means that Aimie always has to give the user feedback showing what she is doing. That’s why there is a different response when Aimie is listening, speaking, or loading. Furthermore, she displays important steps like CPR and mouth-to-mouth resuscitation. Since people are stressed when using the app, the interface has to have other important features: good legibility (high contrast), well-saturated colours, and a font that’s easy to read.


The logo itself was mainly inspired by the human heart. The colours signify the oxygenated and deoxygenated blood that flows from the heart, symbolized by red and blue respectively. You’ll also notice the shape of a typically drawn heart contained in the overlapping ovals. This is because the heart is exactly what we want to save.


Emergencies happen to everyone. Anytime. Anywhere.

Use Aimie. Save lives.
