    Because of the frequency and severe consequences of falls in the elderly, falling is one of the major public health issues. It would be a substantial improvement to reduce the severity and occurrence of post fall injuries. Several technical devices are already used to reduce the risk of falling (e.g. walking aids) or to detect falls (e.g. sensors worn on wrist). However, the underlying biomechanical and kinematical principles predicting falls and their direction remain unknown. Further research and evaluation are therefore necessary in this field. The presented findings will help to close this gap and will be a first step towards an interdisciplinary approach for a personalized design of an airbag system for the prevention of fall-related injuries in the elderly. In a first step, we evaluate possible ways to predict falls and fall directions using kinematic and biomechanical parameters. In a second step we analyse existing products, which aim at detecting falls and avoiding fall-related injuries in regard to compliance and technology acceptance. The research findings of the human movement science and the results of the product-analysis will be transferred into the product development process of fall protection system preventing fall-related injuries in the elderly. One final result will be a design approach for a variable and modular design of a fall protector.

    The brain has only limited ability to deal with complex Problems. Therefore, the developer must be supported to supplement his natural problem-solving behaviors. The SPALTEN-Methodology was described by Albers et al. and constantly developed further in the past 15 years. Furthermore, it was applied consistently in projects and education. SPALTEN is a German acronym and means "to split", "to decompose". In this contribution, the results of an extensive empirical study of the use of SPALTEN in the last 15 years is presented. The study consists of a qualitative preliminary study on basic of interviews (n=15) and a quantitative survey using a questionnaire (n=108) and has a focus on the application and the added value for the user. The results show, that SPALTEN is used in practice by over 80 % of former students and PhD-students, who learned the method in their education.
