Vivifrail is an application aimed specifically at the elderly or the people in charge of them who, by performing a previous test consisting of 6 tests, makes an assessment of the physical abilities of the person and provides a series of personalized physical exercises. The exercises that are performed in this test will be shown in the section "Tests performed".
This app has 3 main categories: My Exercises, My Progress and Information. All of them can be accessed via the main screen.
- My exercises. Within this section are shown the totality of the exercises that it recommends to perform throughout the day. Each of these exercises has an information button that presents a video and a small description of what needs to be done.
- My progress. In this section the application shows at the top a progress bar that will be filled in as the weeks pass. It also shows the initial score that is achieved in the test, the duration of the exercise program and the time that plan has been carried out. Finally, you can also see a calendar that indicates the days to be performed the exercises and rest days.
- Information. This section is divided into 4 other sub-paragraphs, these are as follows:
- Vivifrail Project. It presents information about what the project is and what its objective is.
- It provides a series of documents in PDF format that explain and recommend the exercises that older people should do to improve those aspects(Disability+ Riskof Falls, Frailty, Fragility +Fall Irrigation, Pre-fragility, Pre-Frailty +Fall Risk, Robustness). This section is mainly intended for the people who care for them.
- SPPB test. Explains what the initial test consists
- Healthy lifestyle. Provides some tips for maintaining a healthy lifestyle.
In order to analyze and be able to carry out an evaluation of the application, a series of tests have been carried out to verify its operation. Tests have been performed on both an Android mobile device (Samsung Galaxy J7) and an IOS (iPhone 6 S), the version of the product that has been tested on both devices has been 1.0.2.
To begin testing, it has been decided to use two different accounts to be able to identify if there are any changes in the proposed exercises and the duration of the training. In the first account it has been decided to answer the questions of the initial test with the options that provide only one point, pretending to be a person profile that has many balance and displacement difficulties, finishing the test with a score of 5 out of 12. In the other, the initial test questions have been answered until they achieve a score of 8 out of 12, pretending to be a person profile who has moderate balance and displacement difficulties. All trials of this test are correctly explained as you can see in the images provided below, however, it makes no recommendation as to whether it is advisable to be accompanied by developing these tests.
Once finished and answered all the trials of the test the application notifies you that before you start performing the exercises you will propose it is advisable to consult with a doctor if we can or do not perform them. So, while you do not need to be under medical supervision while exercising, it is strongly recommended that you consult with a doctor.
- Section My exercises. The two accounts show 7 simple exercises that will work a specific look shown in the top right. Different exercises with different durations and number of series are presented in each of the accounts.
- My Progress section. This section is completely identical in the two accounts, the only thing that varies is the initial score information, since both the duration of the exercise plan is the same for the two accounts (12 weeks) and the calendar shows the same days of exercise (Monday to Friday) and rest (Saturday and Sunday). However, it is not possible to see the exercises that are planned for each of the days as the application itself does not allow it.
- Information section. This section is completely identical in the two accounts and as explained above provides some information of interest to the project. In the passports section, none of the documents in PDF format that are provided have been accessed.
It should also be noted that if you do not register in the application on a Monday you will not be able to start performing the exercises until the following Monday, since the app indicates the same thing when entering the section of My Exercises and after pressing the continue button returns to the main screen.
In this section we will measure the ease with which the user can use the application to achieve a specific objective, in this case is to exercise.
The application is very easy to use, has a simple and friendly interface, it consists of three large buttons easily identifiable and understandable, so it won't take much effort to learn how to use it, besides, being so simple if the user decided to stop using it and return to it after a while it would not cost at all to remember how it is used.
It is a highly effective app, since you manage to reach the desired objective as soon as you start the application, also taking into account that, as mentioned above, it does not require a great effort to learn how to use it you can say that the product has a high efficiency in terms of achieving the goal.
With regard to portability, as mentioned above, this application works on any mobile device, whether on a Smartphone or tablet, maintaining at all times a design that suits the device being used, and is also available for Android and IOS devices.
Considering the assigned scores and the analysis of each of the criteria it can be said that the product has a sufficiently good usability in terms of performing most exercises.
In this section, different criteria will be applied to assess whether the application can be used regardless of the capabilities of the user.
Cognitive accessibility – As for the images and icons all of them have a description that facilitates their understanding and, in addition, they are large enough that they can be correctly identified, in addition all the videos that it includes are accompanied by a complete description of the exercise to be performed.
Accessibility for people with reduced vision – The app does not contain any configuration section so both the lyrics and contrasts cannot be modified, making it difficult to use the application to people with vision difficulties. Especially in the section of "My exercises" since the size of the letter is considerably small. In addition, some tests have been performed with the screen reader systems that have Android and IOS devices to check the correct functioning of the application. These tests have been specifically based on checking the labeling of all icons and images that the product has. On the main screen the buttons that correspond to each of the main features are well labeled, however, the button that corresponds to the function of exiting the app has no description. Among the main features that the application has such as the "My Exercises" and "Information" settings are well labeled, the same is not true in the "My Progress" section where the progress bar is not well identified and it is difficult to identify the calendar at the bottom.
Accessibility for people with hearing impairments – People with hearing impairments can use the app without any problem as it does not emit any alert sound and only a visual explanation is made in the demo videos, the exercise description is written after the video.
In this section we will study whether the application has a correct functioning and has no critical failures that prevent its proper operation.
After having tried the product on continuous occasions only two bugs have been found, one minor, which only refers to the impossibility of being able to download documents in PDF format that provide information about so-called passports. The other is much more critical as there are times when the application crashes and the only solution that has been found to resolve this bug is to restart it, this failure occurs only on IOS devices when you finish playing any of the explanatory videos of the exercises.
Privacy and security
As for privacy and security the app does not provide any section within the application that displays privacy policies, so you cannot access them at any time the user wants. The only time you can read the privacy policies, terms and conditions of use is when you download and launch the app for the first time and on the app download screen in the App Store.
The application works in an appropriate way, except for some bugs that, although they have been scarce are very significant, mentioned above. The app greatly contributes to older people staying fit and maintaining a healthy lifestyle in the realm of the physical.
The strength of the application is that, within a large market survey that has been carried out, it is one of the few, not to mention the only one that proposes physical exercise specifically for the elderly and that is also in Spanish, since there are very few available on the application download portals. Another positive point that has much in your favor against other options on the market is to include explanatory videos to make the explanation of the exercise more visual and also this can also serve to check if the exercise is actually being done correctly and, although there is no explanation by voice, the videos are accompanied by an explanatory text describing how to perform the exercise.
Another very positive point is that the application is available for both Android devices and IOS devices and being free makes this an application to consider so that all the elderly can exercise.
- It is one of the few applications on the market aimed specifically at older people.
- The exercises they propose are very easy to perform and do not involve an extreme effort for the elderly.
- The series and repetitions of the exercises are adapted to the score obtained in the initial test.
- Images and icons have a description that helps their understanding.
- Explanatory icons are the right size to facilitate viewing and understanding.
- The application is completely free.
- It would be interesting to check the playback of the videos in IOS to find the error that causes the application to crash.
- It would be interesting to add some basic settings to, for example, be able to change the font size and type or contrast of the background.
- It would be interesting to be able to click on a calendar day and see the exercises that are planned for that day.
- It would be interesting to be able to see the total exercises that the app can provide.
- You could consider reviewing icon and image labels to improve performance with screen readers.
- It would be interesting to provide users with a document informing how their data will be processed.
