In this paper we present a conceptual solution of modular panel for measuring health parameters of the elderly. The conceptual solution was followed by a study that analyzed the design and evaluated interface of the system. Modular panel contains sensors, processing unit, and interface enabling data acquisition and communication between the user and the medical staff. Positioning of the panel within the residential unit was determined by the categories of actions which it should provide and functional areas of typical housing unit. Interface design is based on a specific type of users and is on the basis of the type of data that should be collected and displayed. Evaluation of interface is conducted by using two user groups, where the first is made up of people older than 60 years and represents the interest group of the study, while the second group consisted of people younger than 60 years as the control group. The collected data were analyzed and the results indicate that the simplicity of the interface suits good to the users. Elderly users need more time to conduct certain commands, but most of them understood interface completely. The limitations of the system, such as lack of information provided for the users, will be considered in the future work. [ABSTRACT FROM AUTHOR]
