Abstract:
The multi-touch context is a poorly explored field when it comes to usability and User eXperience (UX) evaluation. As any kind of system, it must be properly evaluated in order to be truly useful. A Systematic Mapping Study (SMS) showed that there is no technologies being used to evaluate the UX and usability of multi-touch systems that were specifically built for it. The use of generic technologies can leave behind important perceptions about the multi-touch systems specificites. To fill this gap, the User eXperience and Usability Multi-tiuch Evaluation Questionnaire (UXUMEQ) was created. UXUMEQ is a questionnaire that seeks to evaluate the UX and usability of multi-touch systems taking into account the most relevant aspects being used to this end, such as performance, workload, intuition, error tolerance and others. As any new technology, UXUMEQ must be evaluated in order to be improved. In this paper, we carried out a quantitative analysis to verify the public acceptance of UXUMEQ
when compared with generic technologies being used to evaluated multi-touch systems. This analysis showed greater public acceptance about UXUMEQ regarding usefulness and ease of use. We also invited Human-Computer Interaction (HCI) experts to inspect UXUMEQ through a qualitative study. Their perceptions were collected and evaluated through the Grounded Theory method, that will contribute to provide a most refined version of UXUMEQ.
