Demographic change and the aging population push health and welfare system to its limits. Increased physical fitness and increased awareness for health issues will help elderly to live independently for longer and will thereby reduce the costs in the health care system. Ex-ergames seem to be a promising solution for promoting physical fitness. Still, there(More)
As the result of a traffic accident, a man was seriously injured. Investigators found him outside the vehicle he had presumably driven. He was taken to the hospital in an unconscious state and there received a number of blood transfusions. Bloodstains found inside the car were collected and sent for comparison with a posttransfusion blood sample of the(More)
A young girl was the victim of a severe dog attack. An animal, suspected of having caused the attack, was later impounded for investigation. Microclots of blood, recovered from the dog's fur, were analyzed by STR DNA. Results showed that this blood was not related to the biting. Other forensic evidence--hairs, fibers, and odontology--failed to connect a(More)
This study compares the effect of using tangible robots to using visual representations for introducing seventh graders (12 to 13 year old) to computer programming. The impact was measured on learning outcome, self-efficacy, class feedback and attitudes towards STEM (science, technology, engeneering and mathematics) topics. Results show that using robots to(More)
With the increase in data availability and data volume it becomes increasingly important to extract information and actionable knowledge from data. Information Visualization helps the user to understand data by utilizing vision as a relatively parallel input channel to the user’s mind. Decision Support systems on the other hand help users in making(More)
Textile user interfaces for smart homes offer novel intuitive input gestures and may lower acceptance barrier for technophobic or elderly people. To understand the users' requirements of smart textile input devices, an Adaptive Conjoint Analysis with the attributes wearability, functionality, haptic, location, and components was carried out with 100(More)
