In this technical check we are going to analyze the use and configuration of Aipoly vision on Android. In any case, in the social validation we have worked with the application in the IOS operating system behaving in a very similar way.

The version of the application analyzed is v1.0.2, the application has an average size of 35 MB that increases as the application is used, this is because it has a large image database that allows the use of its general identification functionality even without an internet connection, which we consider a success.

The application is easy to find and install, although the space dedicated to it in Google Play has the same problems that appear during its use, there are only small parts translated instead of having chosen to translate all the descriptions, and as can be seen in the Google Play image uses unreviewed machine translations with inappropriate language "Sight the blind and partially sighted ...".

In our opinion, dedicating some effort to the correct translation of the functionalities, tutorial and space in Google Play of the application summarizes a lot.

The application has 3 free functionalities and another 6 paid ones. We are going to delve into the free functionalities for comparison with the other 2 chosen applications.

In general, of the 3 free functionalities we will use the general identification functionality and the color identification functionality that are available in the 3 applications. Regarding the “navigation” functionality labeled with an arrow, it should be noted that it is a way of identifying basic objects that can be found on a walking tour of the city.

The first screen that is activated after installation is a tutorial that summarizes the functionalities of the application whose defect, as already mentioned, is that it does not have a translation into Spanish even though we have selected Spanish as the main language in the menu. setting.

Configuration options

The configuration options can be found by accessing the “settings” window through the main menu.

In this menu shown in the previous image we can find options such as the activation or deactivation of the narration voice, a detail that may be of interest to people who use Talkback or Voiceover since it allows deactivating the automatic reading of results that is too insistent and perform only reading the result every time I put myself in that position with the screen reader.

On the other hand, the language configuration is allowed, in this case the selected language only affects the results that it delivers after each identification, since as we have pointed out previously, the rest of the menus remain in English.

The application allows deactivation of the auxiliary light for the camera, which is automatically activated by default when the identification functionality is active.

This is recommended in cases where the exterior lighting is adequate since the fact that the auxiliary light is on generates a large battery consumption and heating of the terminal.

Another of the configuration options that we mention in the color identification section is the selection of the number of colors that it allows to identify, allowing us to select between 30 or 900, in our case we consider the simplification in 30 colors adequate.

The “Keep awake” configuration option selected by default allows you to keep the application in the foreground all the time, while deactivating it the phone will lock up after a certain time set by default in Android or IOS.

Finally, the option "Show onboarding" serves to show the tutorial again.

General identification of objects

This functionality is labeled "general" for screen readers.

As mentioned at the beginning, both this functionality and that of color analysis can be used without the need for data connectivity, which is an advantage over the other 2 analyzed applications that need connectivity for analysis.

We have identified numerous objects with the application whose detailed analysis appears in the social validation of this review.

From a technical point of view we can point out that considering that the application does not use the network to contrast the image with an online database, the number of images correctly identified is very satisfactory, although the system fluctuates a lot at the time of transmitting the result and should indicate a unique result for each pointed object.

During the constant use of the application we appreciate that the consumption is high, this is because the application makes use of the additional light of the phone to improve the illumination of the objects in focus, added to the use of the camera and the internal processing of the information to identify the images.

To solve this problem and at the same time improve the user experience, it would be recommended to implement a stop and start button that allows both the camera, the light and the processing to only be activated at the moments when the user decides to identify an image.

Color identification

This functionality is labeled "color" for screen readers.

The quality of color identification varies greatly with light but is quite good in good lighting conditions.

It is advisable to reduce the number of colors offered as a result to optimize identification, for this it is necessary to enter the "settings" menu and select "simple (30)" in the color option.

The following images show some satisfactory color identifications.

Payment functionalities

To access the payment functionalities that are not the subject of this review, it is necessary to introduce a means of payment, which is a deterrent for users.

We would recommend allowing you to enjoy these functionalities without the need to enter said means of payment.

Highlights

• The large number of images and colors correctly identified taking into account that the internet is not used.
• The usefulness of the functionalities offered for free.
• The speed of identification.

Improvement points

• The excessive information that is offered in each identification without the possibility of reducing or managing it.
• The excessive consumption and heating of the terminal, however, it is positive that some aspects such as the auxiliary light can be deactivated.
• It is recommended to translate the menus and tutorial into the different languages ​​in which the application is offered.
• The need to provide billing information for the 7-day trial period of the payment features is a deterrent for the user.

The following table shows a comparison of the technical verification criteria of the 3 applications compared.
