With the fast evolution in the development of applications for mobile devices, the study and adequacy of usability evaluation methodologies in this context is becoming an increasingly demand. Current techniques and equipment particularly adapted to these types of interfaces, such as specific eyetracking equipment for mobile devices, are trying to offer a solution to contexts related to mobility. However, due to known physical restrictions, especially the limited size of displays, data registered by this kind of equipment is limited to qualitative data. These restrictions are especially strong when collecting data from eyetracking techniques. Further study is needed to assess usability in mobile interfaces quickly and comprehensively. This paper shows a state of the art review on the mobile usability evaluation field, specifically focused on the application of eyetracking techniques in usability testing for mobile interfaces. Once related handicaps and awkwardness's are identified, an agile method for exploiting desktop eyetracker equipment in combination with mobile devices is proposed. The point is coming into play the same facilities used in traditional usability testing in order to obtain qualitative and quantitative data. An experimental study of the proposed method has been carried out for two purposes. The first one is to prove the efficiency and applicability of the method, in comparison to existing options. The second one is to deeply analyse quantitative data extracted from the experiment related not only to the gaze, but also to the visual cognition issue in the exploration of the interface. Initial findings from this study are presented.
