Trackfit Project
The TrackFit project aimed to develop a smartwatch app that helps users monitor their heart rate during workouts. The app would notify users on their smartwatch when their heart rate exceeded the recommended zone for their selected activity.
Key Features
Problem Statement
Many individuals engage in physical activities without adequate monitoring of their heart rate, which can lead to overexertion or inefficient workouts. The lack of real-time heart rate feedback poses potential health risks and prevents users from optimizing their exercise routines.
Goals and Objectives
The primary goals of the project were as follows: Develop an Android smartwatch app to capture the wearer's heart rate. Create a companion Android mobile app for processing heart rate data. Implement an alert system to notify users if their heart rate is out of the recommended zone for their chosen activity.
Research and Planning
Conducted a literature review on heart rate monitoring, wearable technology, and mobile app development. Analyzed existing heart rate monitoring apps and devices to identify strengths and weaknesses. Defined the target user personas, including fitness enthusiasts, beginners, and individuals with specific health goals. Created a project plan outlining development phases, milestones, and deadlines.
Design and Development Process
Requirements Gathering: Collaborated with potential users to understand their needs and expectations. UI/UX Design: Created wireframes and prototypes for both the smartwatch app and mobile app to ensure a user-friendly interface. Smartwatch App Development: Utilized Android Studio and the Wear OS SDK to develop the app capable of real-time heart rate tracking. Mobile App Development: Developed the companion app to receive heart rate data, process it based on user profiles and activity types, and trigger alerts. Integration: Established communication between the smartwatch app and the mobile app using Bluetooth technology. Alert System: Implemented an algorithm to determine heart rate zones and notify users accordingly.
Challenges and Solutions
Communication Challenges: During the course of the project, maintaining consistent and effective communication within the team presented a challenge. Solutions included establishing a structured communication plan, utilizing online collaboration tools like Slack, and holding weekly virtual standup meetings. Algorithm and Battery Drain Challenges: Developing an algorithm to capture and process heart rate data on the companion app while minimizing battery consumption presented a technical challenge. Solutions included collaborating with mentors to optimize the heart rate processing algorithm, implementing a data batching strategy, and utilizing battery profiling tools to measure the app's impact on battery life. Nervousness with Final Presentation: As the project approached its conclusion, apprehension and nervousness regarding the final presentation in front of teammates, class members, and faculty staff became a personal challenge. Solutions included dedicating ample time to rehearse and refine the presentation, organizing mock presentation sessions, and practicing mindfulness techniques to manage nervousness. By addressing these challenges, the TrackFit project demonstrated the ability to adapt to unforeseen hurdles, collaborate effectively despite communication constraints, optimize algorithms for efficiency, and manage personal apprehension in high-stakes situations.
Results and Impact
Successfully developed a functional smartwatch app that accurately captured and transmitted heart rate data. Implemented a responsive mobile app that processed heart rate data and delivered timely alerts to users. Conducted user testing sessions, receiving positive feedback on the app's usability and effectiveness in improving workout safety.
