<aside> ⌚ Area of Focus: for design project three, we could chose to design a personal monitoring device or technology for automating tasks in the home. We chose the personal monitoring device.

The decreasing numbers (6 - 1) show various increasing heart rates, and how they appear visually on an ecg. This method of reading an ecg is very fast, and is called the large block method (image courtesy of https://ecgmedicaltraining.com)
<aside> 👤 Targeted Demographic: any patient with a cardiac condition characterized by a increase in heart rate, also known as tachycardia (rapid abnormal heart rhythm).

<aside> 🗝️ Response: We looked at the sensors and output devices, and I stepped up to the plate to suggest a demographic. The group agreed with it, and that’s what we stuck with.
</aside>
<aside> 🔒
Obstacle: It is important to mention that selecting a target demographic was actually very difficult. Our previous two design projects were very cut and dry with who we were supposed to help. In this project, we were effectively given a blank page with which we could write our own story.

Our Design Project 3 team consisted of four team members. This team was further split into two sub-teams: a coding sub-team and a modelling sub-team. I was a part of the coding sub-team, so I was responsible for writing the code that our device would use, as well as wiring the breadboard our device used. Beyond this, I was also the Coordinator of the group, which meant I was responsible for organizing meetings outside of class hours as well as keeping a record of everything discussed during those meetings.

<aside> ☝ Design a device/system that actively detects the onset of cardiac conditions characterized by increased heart rate. Given an increase in heart rate, the device should alert the user; in the event of a true alarm, emergency personel will be contacted.

Following the selection of our targeted demographic and the development of our need statement, it was time for each of us to develop some preliminary design ideas. The meaning of this is to propose a large number of concepts, and then as a group isolate which one is the best.
Concept 1 - The Arc Reactor
Concept 3 - Body Air Bag
Concept 2 - Ear Clip
Concept 4 - Alert System
Concept 5 - Utility Belt
Concept 7 - Wristband
Concept 6 - Chest Harness
Concept 8 - Chest Harness
Once all of us had generated two ideas each, it was time to evaluate them. In IBEHS 1P10, we are taught to use pugh matrices to evaluate ideas. This allows for a direct comparison between all ideas to the DATUM concept (common denominator). After comparing each concept with various criteria, a total score is calculated. The concept with the highest score is the best concept.
This pugh matrix indicates that the highest-scoring concepts were concept 2 and concept 7.
<aside> 🔒 Obstacle: As can be seen in this pugh matrix, Concepts 2 and 7 were tied for the best concepts. We were unsuccessful in selecting a single concept to pursue. This would require additional decision-making.
