Abstract

Intelligent Voice Assistants (IVAs) are a new type of technology that act as personal assistants, task managers and in some situations even act as a "personal friend", as they are embedded in the most used devices in the world, smartphones. The way these IVAs work can stimulate or discourage the use of this and other new technologies, for this reason, systems assessment becomes a tool fundamental for the user experience and for the design and construction of the systems interface. Designers, project managers and all those who are involved in a project aim to offer a good user experience. For this, two evaluation methods were used to obtain different views on the usability problems existing in the personal assistant Google Assistant. The first evaluation method used in the first phase of this work, was the MALTU methodology, applied in comments left in the Google Play Store app store to obtain information related to IVA, in this case, to obtain Posts Related to Usage - PRUs. At the end of the application of the methodology, graphs were generated that interpreted indicated the main usability problems of the IVA. For the second phase of this work, the results obtained in the application of the first evaluation method were considered, with the objective of a remote evaluation focused on the usability problems already highlighted in the first phase. For this reason, the creation of usage scenarios as a way to guide the evaluators during the performance of the tests, as a way of not leaving gaps in the moment of the tests’ execution. And so, obtain comparative results of usability problems related to the use of IVA.
