Quiri: chronic pain assessment for patients and physicians.

We introduce Quiri , a holistic design concept for pain assessment and documentation. In this paper, we present the design studies of two mobile interfaces - a tablet app especially designed for children and adolescents and a smartwatch app for adults with chronic pain. This case study aims to firstly gain a better understanding of the preferences and needs of pain patients and physicians. Secondly, it describes the design process we took to arrive at the final design of Quiri . Quiri was developed based on the IEC 62366 usability standards for medical devices. The results of the design studies form an interdependent system which is complemented by a web user interface for physicians for the evaluation of the data collected in the mobile applications. Initial qualitative feedback from physicians indicates that Quiri is useful and appropriate for supporting pain therapy.
