Heart rate tracker is useful health application which uses the mobile optics and application to measure the Beat per minute which is the heart rate of user. The primary function of the application is to measure the heart rate, and based on the activity of the user, generate report guiding the user for better meal and diet. The design of the application uses a unique user experience and user interface design that will be used by all types of users. The user segment is mainly online and can be downloaded from the online play stores of mobile platforms after development. The mobile user needs to allow to use the camera optics and the flash light of the mobile to measure the heart rate. If a phone does not have camera or flashlight then the application can not be used. Users can use it regularly or to monitor any health issues related to heart.
The platform for the app is mainly mobile hence it will be available on Android and IOS as these are the most common mobile operating platforms which the world user’s mostly have. The application promptly uses the camera and flashlight hence it can not be accessed through web and not developed as web application. A computer or personal laptop do not have flash light usually. It can also help the health community as they will need only their smartphone to measure one’s heartbeat. This report discusses about the Human Computer interaction between the heart rate mobile and its end users. To represent the user interaction and user interface the report represents the sketched version of Heart rate application screen design, mock up and series design showing as story board. The report discusses about the story board scenario, functionality and system feedback on interaction. Lastly the report concludes with further improvements and implementation of the Mobile application.
The widespread adoption of smartphone allows developers to improve its potential day by day. In healthcare services, it can also be used by the common people who does not have money to visit doctors or they cannot visit in such pandemic situation of Covid-19. With use of sensors and devices the mobile can be equipped with helpful data gathering devices and process it to help people. The main purpose of the technology is to ease people’s life in their day-to-day activities. As the technology gets more advanced, it becomes less likely for the people to do physical activities to measure or maintain their health. In present, heart related diseases have become more general than previous. Every second or third person around the world has or more likely to get heart related disease in future. The rate of heart attacks has increased and more often in younger group range. With technology the health infrastructure has also grown around the world. We can find drugs and medicine for any kind of disease in present time. Also, technology has helped different type of tests and diagnostics to be easier to perform. Similarly, heart rate tracker enables the opportunity to everyone to get their heart rate only using the mobile app.
The heart rate tracker mobile application has variety of features and functionality. However, this report will mainly focus on three major functions of the application that a user must perform. The scenario description part describes the each of the scenario which has been considered for this report.
In this scenario the user will be able to measure their heart rate. The entire process requires camera optics and flashlight access. The user will be able to place their index figure on the camera sensor. Then user needs to tap on the begin measurement button in order to record the BPM. The process records the BPM then the system asks the user to select their current physical activity to determine if the BPM resulted is within range or not. It usual to have higher heart rate while doing extensive physical activity. The system creates a record in the system after that and shows the entire details of the session. This record will certainly help in future report and tacking the heart rate monthly, weekly or yearly.
In this scenario, the user will be able to access the mobile app by using their login credentials. If the user does not have any credentials as they may visit the app first time, they need to register themselves using their email id, and create a password for their login. Then the system creates a login record for that user. While login they will enter the created login credentials. The application validates the entered credentials by the user with the saved details of that user in the system. If the validation is successful, system directs the user to the main page of the application. User can now access all of the feature provided by the Heart Rate Tracker mobile app.
The third scenario comes after the measurement of the heart rate in application. As the session data is recorded linked with the user profile, they will be able to produce report and insights to monitor and track their heart rate. The more the history data will be present the more meaningful the insight will be. Less data for one or two sessions will not produce any meaningful data. The report generation will also require the user to tag the session with their physical activity during that session.
This section discusses the design section of the heart rate tracker app and how it is conceptualised to develop the prototype. The design is mainly developed by sketching the screen design for each page of each scenario. Each scenario is represented as user journey through the mobile application. The frame used for the mobile platform is IOS and the design layout is developed for IOS which is consistent throughout all of the pages.
This scenario uses four screen designs which represents the four stages which are ‘place finger’, measuring BPM, add tag and viewing the session results. The first image represents th e home page of the application. User can see the app information by tapping on the I button. On tapping the ‘Begin Measurement’ button, the measuring process will start. The next screen shows the measuring stage where the sensor will measure difference in light refraction caused by heartbeat. The design shows a progress bar which shows the status of the measurement. After completion, the next page provides the option to select, resting, exercising, tired, work, just walking and before bed as activities of the user to tag the session. After selecting the one activity, the next screen will show the session results and a button for generating the report. On screen 1, 3 and 4, user can also access the app menu for other features of mobile app.
In this scenario the first screen represents the register where the user can switch page screen between login or sign up using the navigational pills. The screen shows a form which asks the user for their email address, password and retype the password for confirmation. The email and password fields are represented using the icons. User needs to click on Sign up button to go on next page. The next page asks for email verification where the system sends the verification code on user’s entered email and user nee to enter to validate their identification. After this screen, the next screen shows the login page where users use the same credentials which they used while creating their accounts. After clicking on login button, the system redirects the use to the next page which is the main home page of the application.
The next scenario is to generate report and It also uses four screens for representation. The fist screen shows the session result with a button for generating the report. After tapping on the generate report button the user goes to the next page where the system asks them to select the grouping of report either as Monthly, weekly or yearly. After selecting the report criteria, the system shows the next page which shows the insights and different charts of user’s heart rates tracked on different past sessions. User can click on Save report to save the data. After clicking on the button system asks user by pooping up an alert box, either they are sure to save or want to cancel the save.
By observation of technological use on many health cases and developed design for the Heart rate tracker, it can be said that the assignment has been performed successfully. The hand drawn sketches successfully represent the wireframe of each screen for each scenario of application. The report clearly describes the purpose and motivation of the mobile application project. Apart from that, after the wireframe development it can be implemented on IOS or Android mobile platforms.
