The Orientatech test team has analyzed the CerQana application to verify its functionalities.

Our analysis begins with the installation of the user and family version apps on Samsung S6 and J5 terminals, the application is easily locatable in Google Playstore, its version is light and therefore the installation process did not involve complications.

In any case, the installation of the user app needs to be done by the family member or caregiver in many cases as it is not intuitive for people with cognitive impairment.

"Installation process"

In the installation process it will be necessary to accept all the permissions so as not to encounter problems in certain functionalities of use.

NOTE: At this point it is important to note that the user application takes device administrator permissions.

The purpose of asking for this permission is to prevent it from being easily uninstalled. It is designed so that you can only uninstall it when you click on the deactivate button from the website. When you press this button, an automatic message is sent to the phone that deactivates that permission, closes CerQana, and deactivates it as the default launcher, returning to the usual Android state.

In any case, if you are testing the application and want to uninstall it, it is necessary to access the menu (Lock screen and security / other security settings / device administrator) and deactivate the application as administrator in said menu.

To start using the applications, it is necessary to obtain codes generated in the web portal after registering as users or entering the user account generated on the web, in this case we can use the Premium version for a 10-day trial, after that period the version it will go to Basic automatically at no cost.

"Obtaining the user code on the web"

After registering on the web portal, we enter the code in our application and a user identifier is generated that identifies our terminal from the portal.

"User log in"

The user application runs automatically once installed and displays a simple and easy-to-understand environment where complex functions are removed from any Android screen. In this version of the launcher, large icons prevail, giving direct access to family and emergency contacts, as well as the menu back home, a feature that shows the route to return to the usual home or other locations configured by the family member.

 "User application"

At the bottom there is a button that allows access to the agenda that can be controlled from the web portal by the family member, similarly, another button allows access to the application menu with large icons. The list of executable applications can also be configured by family members from the web portal.

The user is restricted from uninstalling the application by traditional methods, which prevents the family member from losing control unless the family member wishes to unlink the user from the portal.

There is an emergency icon that allows you to make an immediate call to the number identified as an emergency contact and displays your keystroke both in the family terminal and the web portal, we have tested this functionality successfully on several occasions.

The application for family use has very limited functionalities compared to the web portal, in this case the application is used only to receive status messages sent by the user terminal such as: entry and exit in the secure area, calls carried out, etc ...

"Family application"

The application allows you to view the position of the terminal, but when we tested this functionality some errors occurred when displaying the map and we could not guarantee its operation, the application in turn allows you to define a time slot for audible notifications, except for the emergency push whose sound warning cannot be disabled. * 1

The web portal is designed as a control center for the entire system, and it is where all aspects related to its correct operation can be configured.

Among the functionalities, the constant monitoring of the battery and terminal coverage, as well as the GPS position stand out, from the portal you can also access a calendar that allows the user to remember tasks such as going to the doctor, going to school, etc ...

"Terminal status data"

There is total control over the user terminal, through a menu for managing applications and contacts in the user's agenda.

 "Apps and agenda management window"

There is a fall sensor activation functionality implemented in the accelerometer of the user terminal that triggers an emergency call in the event of a fall, this functionality has been tested without much success, the CerQana developers report that they are working to integrate precision external drop sensors.

"Sensor status data"

Tasks and calendar

The web portal in turn allows the assignment of tasks by the family member to the user, in such a way that it activates an alarm with a programmed advance and with a map of location of the destination, this map display functionality has not been shown in a correct in the user application during our tests. *1
