I'm currently applying to masters in Applied Data Analytics , and I need help to make my essay stands out more and meet the word limit requirement (283 to 250).
This is a supplemental essay
, so it will revolve solely on my experience with data & analytics. I have detailed background and my motivation of joining the program in a separate academic Statement of Purpose.
Looking forward to your feedback, and thank you in advance :)
Describe a challenge related to data or analytics that you have encountered.How did you resolve this challenge, and did you succeed? (250 words)
In January 2019, my grandmother, who has a heart disease and lives alone, fell from her bed and fractured her tailbone. Luckily, my family got there fast enough and my grandmother recovered after 2 weeks of intensive care. But I believe that second chances are rare, so I was determined to build a prevention system to ensure the safety and well-being of my grandmother.
I immediately equipped my grandmother with a Samsung Smartwatch, which already comes with a motion sensor, and built a fall detection system with Google Firebase. Every millisecond, her motion acceleration data & timestamp will be transmitted to Firebase cloud, and stored as a JSON integer. Whenever she falls, the motion data value would exceed a certain threshold, which will trigger a call to 911 and a push notification to my family members, along with my grandmother's real-time GPS data.
I also built a system to monitor her real-time heart condition. Every millisecond, the heart rate sensor data in the smartwatch are stored in Firebase. Using the GraphView library, I enabled a visualization of every raw JSON data into a readable graph, so registered family members can easily observe my grandmother's daily heart condition. I also set up a threshold to notify my grandmother whenever she needs some rest, based on her heart rate value.
Today, I have published 3 journals on my Smartwatch Application, which has been appreciated in several international conferences. Most importantly, I have witnessed first-hand how a simple array of heartbeat and motion data can drastically improve my family's life. By obtaining an education in the Applied Data Analytics program, I look forward to transforming the lives of many others with the beauty of data and analytics.
