Follow along as we develop our project!
For demonstration purposes, the team decided to implement a "fall test mode" for us to be able to demonstrate a fall, detection of it and subsequent alerts, without the need for a stronger impact.
With this, the team can confirm that, most of the previously established requirements were accomplished:
On the other hand:
Throughout the week the team focused on fine-tuning the prototype and giving it a more polished look for ElectroDay. We also ran multiple tests to guarantee correct readings and communication between vest, central and mobile application.
A page pertaining to the results of the questionnaire published at the beginning of the semester has also been uploaded
With falls now being detected correctly, the team needs to find an effective way to demonstrate this component to visitors without damaging the prototype.
ElectroDay BrochureAt the beginning of the week, the pitch deck, ElectroDay poster and demo video were uploaded.
The team started planning their setup and demonstration for ElectroDay.
Poster & Demo VideoThis week, we kept testing the fall detection component of our prototype, which will require further adjustments.
The oximeter and dock are mostly completed, and an alert system using LEDs was set up to alert the user when it's time for new assessements. The user is also made aware of how long they must keep their finger on the sensor to assess blood oxygen saturation leves correctly
We also mapped out and wrote the scripts for the team's demo video, which was filmed at the end of the week.
Oximeter Assembly & TestingOn Tuesday, upon meeting with the team's Scientific Advisor, we were able to better define what would be our priorities throughout the incoming weeks. The team agreed to focus on calibrating the IMU correctly, so that it's able to distinguish between common and predictable scenarios, such as the user sitting or lying down and emergency situations, like falling and loss of consciousness.
We also aimed to implement the oximeter into our project, as well as design a dock for it and a notification system to alert the user when it's time for value intake.
Later this week, the team was finally able to appropriately establish a connection between our application and database, now capable of receiving the required data.
Oximeter DockWith the first prototype iteration to be delivered at the end of this week, the team spent their time adjusting the features previously implemented. One of our major difficulties has been calibrating the IMU to the project's needs and potential scenarios, while ruling out false alarms.
Upon the arrival of the correct oximeter unit, we were finally able to start working on and test it for our project.
Due to raised concerns regarding our thermometer model and its accuracy to measure body temperature, a few tests were run on a member of the team to acquire and compare a set of measurements between our model and a digital clinical thermometer. All values obtained through our model were in line with those measured by the clinical thermometer, with body temperatures around 36 degrees Celsius.
Regarding the application, we have yet to set up the alarm/notification system in case of emergency or concerning readings.
DS18B20 & Clinical Thermometer ComparisonThroughout this week, the team started to implement the collected IMU into our project, with the heart rate monitor and panic button being finalized this week.
Due to being delivered the wrong oximeter model for our prototype, the team is still waiting for a new unit, which will consist of a separate feature from the vest.
Other members of the team have also started working on the interface for our control center, as we continue perfecting our app's UI and respective databases.
Finally, we have made a few relevant updates to our website, with a gallery and questionnaire pages soon to be added.
Heart Rate, IMU & Panic Button TestAfter some difficulties, the group finally managed to pick up the IMU, the new heart rate monitor, and oximeter. Schematics for both the vest and oximiter componentswere done resorting to KiCad.
With the help of the group's coordinator, we started working on making the heart rate band functional for our project, now being able to read and transmit the measured values.
Meanwhile, the user's interface of our application started development, along with the work on the database.
Vest & Oximeter Components SchematicsThe group was able to present its project on Tuesday, as well as receive crucial feedback regarding what will be the final delivery. After the advice given by its Coordinator and Scientific Advisor, the team started, on the side, working on a new page for our website regarding the results gathered in our questionnaire.
A few changes/updates were made regarding the prototype's materials:
Later in the week, we started assembling the vest's electronic components available to us at the moment, mainly the thermometer.
The team also started developing the central's database, now being able to create and add certain patients' charts to each medical professional's care, via terminal.
Thermometer TestDuring the week we were able to pick up a few of the materials the team had solicited, though we have yet to receive:
One of the members also mapped out the application's interface.
Due to a nationwide blackout, the presentation of the team's pitch has been delayed by a week, now scheduled for May 6th.
Application SketchOn the last week before exam season, the group perfected and submitted the finalized version of the project's pitch deck, after taking in the feedback given by the team's Coordinator and Scientific Advisor. The pitch will be presented to the class at the beginning of week 11.
With the feedback given in the previous week, the team finalized and submitted the list of the materials needed for the development of our prototype. A provisional version of the project's pitch deck was also submitted for critique.
After establishing contact, two members were able to conduct one final interview with our Scientific Co-Advisor.
On the sixth week, the group refined and submitted, for approval and possible feedback, the list of materials needed for the prototype.
Other members of the team also started working on an interim version of the pitch deck.
This week, some members of the team focused on updating the final list of requirements, taking into account the feedback received throughout the interviews, as well as from the questionnaire's collected data.
The group also started working on the final list of materials, to be submitted the coming week.
List of RequirementsOn the fourth week of the semester, the team gathered 97 responses to the questionnaire and began treating the data collected to be ready for publishing.
We were also able to interview, in person, a General Care Nurse at a public hospital, and an Informal Caregiver to get some feedback regarding the potential of the vest inside the home. We then wrote the final drafts of the information amassed in these two weeks.
Another portion of the team worked on elaborating the final list of the materials needed for the project. With the help of the results collected on the in-person interviews, we started writing down the main solutions that this project requires.
Read MoreThe team published a questionnaire aimed towards healthcare professionals, students and (in)formal caregivers at the beginning of the week and launched its first website and blog's iteration.
The group also started the in-person interviews with healthcare professionals and potential users of vest for future testing. Throughout the week, we interviewed two General Care Nurses at a private hospital's in-patient unit.
Go to QuestionnaireOn the second week, a few members of the team had an extra meeting with the group's coordinator to discuss the missing details in preparation for the final project proposal, submitted at the end of the week. Additionally, we were given information about the website and blog.
During the week, the team planned a google forms and interview scripts directed towards healthcare professionals and students, and also caregrivers, in order to receive more feedback about the project. Besides that, we also started brainstorming the materials and equipment needed for the prototype.
Materials & Project SchematicOn the first week of the second semester, the team had their first in-person meeting with its coordinator, Professor Pedro Vitor. We also had the opportunity to meet other teams and know more about each project.
Throughout the week, the group added the final touches to the project proposal and started mapping out the project's website and blog, as well as selecting possible interviewees for the incoming weeks.
