In order to develop easy-to-use multimodal interfaces for mobile applications, effective usability evaluation methods (UEMs) are an essential component of the development process. Over the past decades various usability evaluation methods have been developed and implemented to improve and assure easyto- use user interfaces and systems. However, most of the so-called ‘classical’ methods exhibit shortcomings when used in the field of mobile applications, especially when addressing multimodal interaction (MMI). Hence, several ‘classical’ methods were broadened, varied, and changed to meet the demands of testing usability for multimodal interfaces and mobile applications. This chapter presents a selection of these ‘classical’ methods, and introduces some newly developed methods for testing usability in the area of multimodal interfaces. The chapter concludes with a summary on currently available methods for usability evaluation of multimodal interfaces for mobile devices.

Usability Evaluation Of Mobile Applications

During the evaluation of mobile applications and services it is typical to focus on providing solutions for technical problems. In-depth studies on what kind of classical methodologies for usability evaluation can be used and how these classical methods have to be adopted for usage in mobile scenarios are rare. But it is commonly accepted that data collection for evaluation of mobile devices and applications is a central challenge, and that novel methods must be found for that (Isomursu, Kuutti & Värinämo, 2004).
