A significant increase in multi-touch interactions is notable with the expanded use of smartphones, tablets, and tabletops. Multi-touch systems are software that uses the user's fingers to perform some action. These systems need evaluation before being available in the market to improve the interaction and general user experience. In this context, User eXperience (UX) and Usability are relevant criteria related to multi-touch systems quality. Therefore, we performed a Systematic Mapping Study (SMS) seeking to identify evaluation technologies used by professionals and researchers to evaluate the aspects of Usability and UX in multi-touch systems. After the selection process, 65 out of 622 identified papers were selected for data extraction. As a result, 29 different evaluation technologies were identified. Besides, we also obtained characteristics of these technologies, empirical studies, and the multi-touch systems presented in the papers. Our study shows a lack of evaluation technologies focused on the multi-touch context; most do not evaluate Usability and UX concepts jointly; none go under an empirical evaluation since researchers tend to create their technologies to assess their aspects. This SMS presents data about the evaluation technologies extracted and the gaps found over the researched topic, contributing to the scientific and industrial community that evaluates the Usability and UX of multi-touch systems.
