Explorando o modelo MALTU na avaliação de usabilidade e experiência de uso em um dispositivo ubíquo

Abstract

When we refer to the technological revolution, the notion of ubiquitous systems is one of the main issues. The popularization of these devices is justified by the users' need to stay connected. Faced with this technological leap of ubiquitous devices, its usability and user experience did not grow at the same pace. Comments are easily found reporting interaction issues in virtual stores such as PlayStore. In order to help the developers of ubiquitous devices to improve the interaction, this work explores the MALTU evaluation model in order to verify its applicability to ubiquitous systems. The exploration of the model was handled manually in a sample of comments taken from Amazon.com regarding the ubiquitous HidrateSpark 2.0 device. Two evaluations were performed using the MALTU and HUbis methods (specific heuristics for ubiquitous devices) and their results were analyzed and compared in order to verify if MALTU is able to identify problems typical of ubiquitous devices. The results showed that MALTU was able to identify interaction problems in ubiquitous devices, especially when the evaluators seek to find problems related to the user experience.
