SHEEN: Set of Heuristics to Evaluate Mobile Applications that Interact with External Equipment

The heuristic evaluation is a cost-effective method that identifies usability problems with interfaces and interactive systems. In order to perform it, a set of heuristics must be selected, which can be of two types: generic or domain specific heuristics. Currently, with the dissemination of mobile devices and their applications in people's daily lives, several mobile applications that interact with external equipment have emerged, with particularities in terms of their use. The inexistence of domain-specific heuristics for this field, led us to propose our own set following the methodology proposed by Quinones et al. to develop usability and UX heuristics for specific domains. This paper presents the application of such methodology to propose a set of heuristics suitable to evaluate mobile applications that interact with external equipment. For this, we have taken into account 3 mobile applications, and integrated 4 experiments, to improve and validate the results.
