Usability trails were carried out with a simulation of an early version of an intelligent thermostat interface. The multimodal interaction dialog took place in speech, sound, graphics and touch. Usability of new concepts of interaction was assessed. Most user behavior and problems of use were equal for old and young subjects (between 25 and 73 years of(More)
Recent advances in approaches to mixed-initiative user interfaces for desktop applications provide a number of principles, which can be used to embed intelligence in consumer products. An integration of several approaches is proposed towards building an intelligent thermostat that can reduce energy consumption. A statistical model is used to spot trends in(More)
Designers of consumer products usually try to address as wide a range of user needs as possible. Due to various design constraints, such as product size and limited interface mechanisms, typically only a portion of those needs can be supported. This paper discusses efforts to design everyday consumer products that can support a broad range of user goals and(More)
Noise is a direct cause of health problems, long-lasting auditory problems and development problems. Preterm infants are, especially, at risk for auditory and neurocognitive development. Sound levels are very high at the neonatal intensive care unit (NICU) and may contribute to the frequently observed detrimental outcomes of prematurely born infants.(More)
The EU Research Training Network on Augmented Reality in Surgery (ARIS*ER) was established with two aims: (1) to develop next-generation novel image guidance (augmented reality based on medical images) and cross-linked robotic systems (automatic control loops guided by information sensed from the patient) and (2) to educate young researchers in the(More)

Interventional radiology procedures require extensive cognitive processing from the physician. A set of these cognitive functions are aimed to be replaced by technology in order to reduce the cognitive load. However, limited knowledge is available regarding mental processes in interventional radiology. This research focuses on identifying mental(More)
The majority of medical device incident reports can primarily be attributed to use error. Greater attention to human factors and usability during development of a medical device could improve this situation. However, recent studies have shown that companies do not find the application of a sound usability engineering process according to international(More)
By means of continuous recording of the positions of the trunk and head, an investigation was carried out to examine the effect of the Erasmus office-desk - a desk with a 10 degrees inclination - on sitting posture whilst reading and writing, sitting in an adjustable chair at an adjustable table. The posture assumed by a person who is doing mixed reading(More)
