Continuing with where we left off last week, we met with Dr. Carter last Friday to get his final input on the device. We were specifically interested in his thoughts on our software with a GUI interface and the hardware specifically with questions about the mobility, comfortability, and flexibility of three of our designs. Our first design was for a finger set up using cable clamps as the predominant fixture point for the potentiometer. The second design utilized goggle straps to secure the potentiometer. The last design we presented was for the wrist using a slide potentiometer fixed onto the wrist with velcro and bungee cords. Dr. Carter suggested that we do what we can to increase processing time and make the interface with the software as intuitive and simple as possible. This week, Chris helped us pivot and adapt to meet this requests by switching our data processing from Matlab to Arduino. Dr. Carter also emphasized making the hardware component as realistic and viable in a clinical setting as possible. He preferred that we focus on developing our finger design with goggle straps over both the more rigid cable clamp design and the wrist set up. Since the priority thoroughly is accurate feedback through a flexible device that suits a patient’s condition, Dr. Carter suggested we just focus on developing the finger components and if need be, ignore the wrist. Earlier this week, we talked with Dr. Yin to clarify aspects in the report such as what he meant by ethical issues and evaluation of meeting our specifications. Dr. Yin confirmed that while the client may be ok with adjusting his requirements for the completed project, we would still be judged at the end of the day whether we met our original design specifications that we covered in our verification and validation report. Currently, the group is working on building the mechanical design and testing the device. In addition, we are preparing the final report and presentation.
