Accessibility

Visually impaired people

As we have commented previously, the app itself constitutes an accessibility option for the people of this group, we can affirm that its function is very careful and it fulfills its objective in an outstanding way, since the recognition by camera of the different modes is very good except in some specific cases, also by having it correctly labeled for screen readers such as Talkback, the features of the app that do not reproduce voice synthesis, grant complete accessibility to the people of this group.

People with hearing difficulties

The application presents some native option for people with mild hearing difficulties, such as the speed and tone of the voice of the synthesis of the app, which can help users of the group, but its use for people with a total hearing disability, You could activate the vibration option in the app to confirm actions, this coupled with the fact that it also shows on the screen what the camera recognizes, they make it possible for them to use it without problems, although the app is not intended for this group, although the experience may not be as satisfactory as in the case of people with vision difficulties.

People with physical difficulties

Although the application is not focused on this group, it could be used with the various necessary adaptations, if the disability requires it, such as those that affect the motor skills of the upper extremities. This part of the group could use it through devices that allow holding the device to focus on what the user wants the app to recognize, it would be somewhat more complex to handle the app but it would be functional for this part of the group, who could use the app in a way acceptable.

User experience

Next, we analyze the degree of user satisfaction when using the application. In addition, to study the utility provided by the app.

Interaction

It is important to highlight how successful the application is when it comes to meeting the objectives it sets, providing a very successful functionality and fulfilling its objective in a satisfactory way. The development of it together with a team of people with vision difficulties makes the app feel polished, with a very simple and easy-to-use interface, together with the correct operation with screen readers such as Talkback, they make it an app in If using it is a remarkable experience, it is also important to mention that everything that it recognizes is reproduced by voice synthesis and on the screen, also serving those with hearing disabilities and mild vision difficulties.

Finally, comment that the application is quite attractive and well developed, making its use light and interesting.

Conclusions

Lookout is a very complete application, with a remarkable design and development, in which the work behind it can be appreciated from the first use, the recognition functions although there are not many, they are essential to help people visually impaired in their day-to-day and they are more than compliant, although sometimes they do not recognize what they focus on, which makes it possible to affirm that they still need some optimization or improvement of the app's functionalities, although these situations are not very common, Well, it included support to recognize more bills other than dollars, although the app is constantly updated and they plan to include support for euros, for example in the future, since dollars greatly limits the number of users who can use that recognition.

Highlights

• Exquisite functionality: Remarkable development of the app, fulfilling what it promises quickly, coupled with a very easy-to-use interface and designed to give the greatest possible accessibility.
• Great help: The use of the app by people with visual disabilities, helps them widely in their daily tasks, being a necessary application for the group.

Improvement points

• Include more types of recognition and polishing than the existing ones: although it contains the basic recognition options for the day-to-day, more options may be needed, which further improve people's accessibility, so adding more functionalities would be very interesting. Also, improve or correct small bugs that rarely occur when we perform recognition of existing functionalities.
• Compatibility with IOs: many disabled users use IOs because it is considered an operating system that provides many accessibility options, together with the large number of users in the IOs community, they make the app inaccessible to many interested parties, so a version for IOs, would give a good boost to the community of the app, in addition to expanding the range of possible users of it.
• Improve banknote recognition: currently it only recognizes dollar banknotes, it would be vital to add support for more types of coins, in addition to improving their recognition, since banknote reading is the functionality that causes the most problems.
