Starting Point
Drowning has become the 3rd unintentional death cause in the world. According to data from World Health Organization, 37200 people die from drowning every year, which means 42 people die every hour per day.
After desk research, we mapped out various time period when a person is drowning, starting from pre-event to afterwards.
The chart indicates that the entire rescue process, even when accounting for all stages, takes no more than three minutes in total.
Therefore, we defined our challenge as:
HOW MIGHT WE enable drowning people to communicate with lifeguards and save life in such a short time emergency situation with easy access and understanding of basic but important information?
Process & User Test
After ideating about the placement and function of our products, we came to a conclusion that our device should aim for low-tech, portalable and easy to activate.
Then we started to prototype on the physical form of our device.
After we had our first sketches on everything, we arranged a test session with students from UID to mimic the behavior of saving a drowning person.

A day of a drowning person
Our user scenario mainly can be divided into two kind of situations.
First one is about prediction. If some people accidentally swim into the NO-GO area, they will receive a gentle notification on their device just to inform them to go back.
Second, also our prime user scenario is about emergency.
In this case, he triggers RUSH by himself but it can also be activated automatically as the sensors attached to people's skin collects body data and estimate if this person is in urgency or not.
As soon as he triggers RUSH, the lifeguard get a strong notification from his tablet. By using the AR version, this helps lifeguard to locate the drowning person exactly and rapidly.
Under the water, the lifeguard is guided by the spatial audio which gives them feedback about which direction they should be heading.
As they approaches him, the frequency of the sound in their headset also changes indicating that the person is nearby. Besides, the sound and light made by RUSH are other elements that helps the lifeguard to locate him.
Final Concept
Considering our device's function and it's nature of emergency, we named the product RUSH and created LOGO for it.
Origins from chinese character ' 冲' which means toward, we changed the form of this character to the wristband version of RUSH.
For lifeguards, the interface shows rough location of every person wearing this device and the safe area boundaries in the sea.
When emergency happens, lifeguards can hold the button at the lower right side and scan the sea using the AR function.
The interface shows where the drowning person is, how much time has they been in this situation and where this person is floating to. It also shows the fastest route and the water entering point lifeguards should take to save a person's life.

RUSH can be more than a wrist band. By using the clip on its back, you can place it also on everywhere on your clothes. Thereby, more choices are added for everyone.
