Successful markets are populated with products which actually meet the user expectations well. A key contribution to determine the proper functionality of products, systems and environment design is provided by “human factors technologies and services”: usability analyses, studies on human behaviour, research on motivation, advertising and marketing, and security research are nowadays increasingly applied for the structuring of our habitats – for the design of shop floors, web and product design, interaction design, urban and traffic planning, and guidance system designs. The various applications in this area require a qualitative and increasingly quantitative acquisition and interpretation using significant parameters that describe physical and cognitive human activities. For the underlying human sciences values on behavioural data, attention, stress and emotional status are essential to determine the user acceptance of products, services, user interfaces and guidance systems. The required progress on specifically miniaturised, multi-sensory measurement systems and associated quantitatively driven interpretation models is so far still missing and FACTS is aiming at filling this gap.
