Data acquisition by multidomain data acquisition provides means for environment perception usable for detecting unusual and possibly dangerous situations. When being automated, this approach can simplify surveillance tasks required in, for example, airports or other security sensitive infrastructures. This paper describes a novel architecture for(More)
For a long time, emotions have been ignored in the attempt to model intelligent behavior. However, within the last years, evidence has come from neuroscience that emotions are an important facet of intelligent behavior being involved into cognitive problem solving, decision making, the establishment of social behavior, and even conscious experience. Also in(More)
This paper presents the framework of a novel approach to combine multi-modal sensor information from a network of distributed smart nodes possessing audio and video modalities for gaining valuable supplementary information compared to traditional video-based surveillance systems or even just CCTV systems. The nodes are equipped with wireless communication(More)
Freezing of gait is a phenomenon common in Parkinson's patients and significantly affects quality of life. Sensory cues have been known to improve walking performance and reduce freezing of gait. Visual cues are reported to be particularly effective for this purpose. So far, sensory cues have generally been provided continuously, even when currently not(More)
Building automation systems (BASs) have seen widespread distribution also in private residences over the past few years. The ongoing technological developments in the fields of sensors, actuators, as well as embedded systems lead to more and more complex and larger systems. These systems allow ever-better observations of activities in buildings with a(More)
This paper presents the framework of a novel approach to combine multi-modal sensor information from audio and video modalities to gain valuable supplementary information compared to traditional video-based observation systems or even just CCTV systems. A hierarchical, multimodal sensor processing architecture for observation and surveillance systems is(More)
