EVA

EVA (Ericsson Nikola Tesla Virtual Assistant) is a voice-controlled interface.

EVA (Ericsson Nikola Tesla Virtual Assistant) is a voice-controlled interface intended for people with visual impairments with additional motor difficulties or difficulties in using modern technologies, as well as immobile people.

The aim of this project was to enable blind people with additional motor difficulties to voice control devices that have a touch screen. Such persons include persons without one or both hands, immobile persons, and the elderly who are unable to operate the touch screen. The project is also intended for people who, due to the difficulty of adapting to new technologies, still do not use smart devices with a touch screen. By such devices we mean smartphones, tablets, or smart watches. Our intention was to bring new technologies closer to people who could never use it, or whose new technology was very limited. Also, the app is useful for drivers as well, as it allows them to make phone calls, dictate and read SMS messages without looking at the phone screen and looking away from the road while driving.

Although there are many technologies in the world today for speech recognition, voice command and text dictation, these technologies unfortunately support a limited number of foreign languages ​​and are therefore inaccessible to many who do not speak languages ​​such as English, German, Italian, Spanish or French. With this project, we wanted to create an experimental solution that will enable the issuance of orders in the Croatian language, as well as in other languages ​​in the former Yugoslavia.

The EVA application currently supports the following features:

Three ways to activate voice activation using built-in sensors or by saying a keyword.
