USER CENTERED DESIGN OF PATIENT USER INTERFACES FOR REMOTE TRAINING SUPERVISION A User Study

Remote training supervision is a new approach that combines medical and IT knowledge into one system. Such a system enables patients with cardiac diseases to continue a supervised training - on an ergometer bicycle and even when exercising outdoors - after rehabilitation phase in a clinic. The goal of the study presented in this paper is to develop user interfaces for an ergometer. These interfaces have to allow an intuitive interaction and to take the different capabilities, needs and preferences of potential users - often elderly people having visual impairments and different IT knowledge - into account. In order to create minimal attention user interfaces it is mandatory to apply user centered techniques, which involve potential users into the design phase of the development process. The evaluation of the study served as basis for the next iteration of the user centered design process and raised new functional requirements to the underlying system from the user's perspective.
