A proof-of-concept visualization to increase comprehension of personal medication schemes

In this paper, we investigate how information visualization techniques can be leveraged to increase patient comprehension of personal medication schemes in order to make it easier for them to explore, explain and understand drug information. Using computer vision techniques, our solution is able to recognize medication boxes, or so-called pharmaceutical packages, which are laid on an ordinary table. A projector visualizes drug information such as interactions, adverse drug reactions, intolerances and the dosage regimen around corresponding boxes. Five prototypes are designed and evaluated following a user-centered, rapid-prototyping methodology. Test participants in our study included both general practitioners (GPs) and patients. Results are promising and clearly indicate that information visualization techniques are an effective means to explore and understand drug information. Even if this system was originally envisaged to be used as a means to improve 'therapy dialogue' between GPs and their patients during consultations, our results show that both GPs and patients think it would be highly beneficial if patients were able to use the system at home.
