Abstract Valorization and interpretation of health data are contingent upon a robust analytical framework. This framework encompasses essential processes such as data cleaning, validation, and the critical evaluation of bias and missing data. A nuanced understanding of these factors is crucial for contextualizing data through stratification, developing comprehensive analysis plans, and addressing interactions, covariates, and confounders. Such meticulous methodologies guard against ‘data fishing expeditions’ that could otherwise lead to erroneous conclusions. Healthybelgium.be exemplifies our approach for deciding on appropriate levels of data aggregation and stratification. This study serves as a foundation for deriving conclusions and formulating hypotheses regarding the health status of the national and various sub-populations. Our discussion will cover the limitations of the questions that can be answered with the available data, the resulting opportunities for data enhancement, and the subsequent valorization of findings for knowledge advancement. Furthermore, we will present the interactive tools (through the use of R Shiny) developed by Sciensano to disseminate information broadly, making it accessible and comprehensible to diverse audiences. These tools embody a balance of strength and limitation, facilitating an informed dialogue among stakeholders. The ongoing refinement of these tools, influenced by continuous learning and insights, exemplifies our commitment to evolving public health intelligence.

In this paper we present a novel approach to text input on large interactive surfaces using a combination of strategies to resolve the inherent difficulties with text input on such a device. Instead of using a conventional full size QWERTY based layout, the idea is to use a very limited set of buttons that, by using word prediction and hints, would only require minimal finger movement. The input mechanism is somewhat related to input methods employed when using keyboards with a limited size and amount of keys, commonly found in phones and other 10 digit keyboards. Given that the main motivation to this approach was not the limited size but rather to overcome the difficult task of locating keys with fingers on a flat and featureless surface, making touch-typing very difficult and requiring frequent visual monitoring of the finger position, we opted to enhance the interaction with easily made gestures, a layout that adapts to the hand anatomy of the user, and easy control over the text prediction.

In this case study, we describe a complex pharmaceutical touch screen software development project in which an appealing graphical design on top of a well-thought user interface elevate the benefits of a good user interface design. Based on this specific case, we emphasis the importance of a clear and simple navigation and interaction in a complex pharmaceutical touch screen application.
