As part of the EU project e-Sense – "Capturing Ambient for Mobile Communications through Wireless Sensor Networks", HFC has been working on intelligent, wireless sensor networks from 2005 to 2007, collaborating with 23 partners from industry and research (among others: Fujitsu, Siemens and Mitsubishi). In a highly user-centered approach, body and environmental sensors were used to facilitate new applications and services which respond in a way that is highly adjusted to environmental conditions, human needs and moods.
The emphasis of our work within the project was based on our long-time competencies in the field of measuring physiological variables and the mediation between technical and user requirements. Among the work packages of HFC was the analysis of user requirements for sensory networks and possible applications, the development of user scenarios as well as the validation of specific example use cases. We examined the heart rate variability, skin conductance and voice frequency in different application scenarios, thus expanding our expertise in measuring mood data. As a result, a reliable classification algorithm was created, which enables our researchers to collect data about a person’s level of activation online. A GUI vividly illustrates the mood change.
