Assisting technologies are the main focus of this book. Every day commodities as well as luxuries for all areas of life inclusive the services which are directly related to the products are examined. The analysed markets present positive macro-economic effects. Therefore in Germany a pilot- or lead market for assisting technologies could emerge due to the demographic development. The estimation of the turnover potential is done on the basis of scenario analyses. The results are contrasted to the demand of private households, taking the willingness to pay into account. As expected between the turnover potential and the demand potential considerable differences occur. Against this background business models are developed with the main focus on different ways of financing taking into account the regulations of the social security system.
