SUMMARY
iHeart is a system consists of wearable technology and application to improve the lifestyle of the individual with heart conditions, particularly atrial fibrillation (irregular heart beat) by making the patients to become more conscious of their heart states and fostering the communication during emergency situation.

DESIGN PROCESS
Survey + Interview -> Persona -> UI
Survey + Interview -> Persona -> UI
To understand the kind of problems that the atrial fibrillation patients face and their needs, I created a survey questionnaire to ask the doctors and therapists who have treated the patients about the patients they faced. Moreover, my teammates also interviewed some patients who had atrial fibrillation.
After summing up the patient's characteristics, I came up with a persona,
Hi, Colton Page!

The persona gave a direction that we needed to monitor the patient actively and enable them to send out warnings when the patient is not feeling well. Thus, I suggested the wearable device to my team.

After talking to doctors, we realized that measuring the heartbeats would not provide accurate diagnosis. Thus, we changed our design requirement from heartbeat to electrocardiogram.
During the interview, the heart patients have mentioned three
pain-points that they had, so we tried to address to make their
situations easier.

First: They fear that they would faint any time and anywhere
without his/her family and friends notice.
without his/her family and friends notice.
Second: They often would forget to take their medications.
Third: They have difficulty in maintaining their exercise schedules.
Thus, we designed an emergency contact group that allows the patients to share the data to their family members or friends or even their home doctors.

We also track their steps and provide visualizations to motivate them to walk at least 1000 steps a day. However, we also thought about the disadvantages of implementing the steps that may pressure the patients or they are unable to walk for that many steps, so we also provide options to allow the patients to track their steps or not.
WEARABLE DEVICE
PRODUCT DESIGN REQUIREMENT
● Lightweight, low profile, waterproof design
● USB port for charging and medical analysis
● Built-in data coverage plan
● Adjustable, magnetic strap (elastomer)
Designed by my teammate
● Automatic and manual emergency alerts: delivers accurate emergency alert
when an extremely pattern appears and connects with hospital and patients’ family.
● Monitors and provide electrocardiogram to visualize heartbeats and also detect heart attacks.
● Encourage user to exercise by tracking steps taken and sleep quality.
● Provides daily health care/prevention tips specific to the users.
ALERT SYSTEM
Manual Detection: When user needs an immediate help and press the side button, the device will alert emergency service and family/close friends.
Automatic Detection: When the device identifies an irregular heart beat pattern, the device will vibrate for 10 seconds and alert friend/family. The user can push the button, which means to stop the alert. Or, after 10 seconds, the device will contact the hospital and user's family/friends.

NEXT STEP
1. Talk to more patients that are related to heart disease and come up with more functions that can support their situations. However, we would let the patients to fill up their type of illness/disease during the on-boarding stage, so that we can provide appropriate functions for them.
2. Change the step goal. I would like the participants to set their own goals, so that they know what they can accomplish and will have more motivations to achieve it.
3. Interview people who have had fainted experiences and see how we help the situation to be better.
