Week 5: Final Presentation, Commercial Showcase, and Wrapping Up PINKEE
By: Qiuyu Chen
As this is the final week before the Shark Tank presentation, our focus was on refining the prototype based on feedback from interviews with Sean and Marty. Their insights highlighted the importance of simplicity and speed in the EMS workflow. We learned that EEG radar plots, while informative, were confusing for EMS personnel, who preferred a straightforward severity score or bar. Since EMS decisions must often be made within seconds — “time is tissue” — a simplified interface is far more practical in the field. Another key takeaway was the importance of aligning with existing standards: BE-FAST is already widely recognized, so it needs to be integrated into our main page, potentially with an objective scoring system attached.
With these insights, we redesigned our interface into a streamlined two-page structure. The main page now emphasizes essential information — such as severity scores and BE-FAST results — while a secondary page, accessible through user interaction, provides more detailed data like radar plots, brain waves, and frequency information. This ensures that our tool remains both efficient for rapid decision-making and comprehensive for deeper analysis when time allows.

We also began creating our commercial video, drawing inspiration from the vintage “Life Alert — I’ve Fallen and I Can’t Get Up” holiday commercial aired on KYW 3 in 1990. Using this reference allowed us to add a humorous and engaging touch, making the video both memorable and appealing to viewers.
On Wednesday, we filmed our commercial, and the process was both engaging and fun. Guided by our storyboard, the commercial demonstrates how the PINKEE node addresses treatment delays and ultimately saves lives. Each team member took on the role of a different stakeholder to showcase the breadth of our product’s impact: Jolene portrayed an EMS professional with 16+ years of experience, Stef as an EMS professional with 19+ years of experience, Agastya as Dr. Finkelstein, a retired U.S. neurologist, and Alex as the patient.
On Thursday, we delivered our final presentation. Although we were initially nervous about being the last group to present, we pulled through and did an excellent job. Our professor even praised us as the most professional team, noting that if this had been a real Shark Tank with investors voting, PINKEE would have been the clear choice. Throughout this Summer Session II in COGS 187A, the members of Team PINKEE have supported one another, shared responsibilities, and worked hard to reach this achievement. Our slides, prototype, and speeches all came together impressively: we included interface comparisons that clearly showed the differences between a suspected stroke and a non-stroke case, and we even made a funding request to the “investors,” explaining how the money would be used.
As our journey in COGS 187A comes to an end, Team PINKEE is proud of the growth we’ve experienced together. From early brainstorming sessions and storyboards to our final prototype and Shark Tank presentation, every step has been a chance to learn, collaborate, and push our creativity further. We not only built a product that addresses a real-world problem, but also learned how to support each other and share responsibilities as a team. This class has shown us the value of design thinking, user-centered research, and teamwork, lessons we’ll carry into future projects and careers.
