Regular work tasks in the washroom of laboratory animal facilities include cleaning of cages and bottles and handling of chow and bedding. These operations largely are carried out by hand. We quantitatively determined the musculoskeletal load on the trunk and upper limbs of washroom employees in an animal facility with a holding capacity of 35,000 rodent(More)
This paper aims to study the effect of structure in a graphical layout on object-location memory. In two experiments several structures have been examined in respect to the performance of object-location retrieval. The results show that beside simple object-to-object spatial relations also the spatial relation of three objects is encoded in human spatial(More)
A novel approach to measure the complexity of human-computer interaction is presented. A complexity measure is defined, which refies on information-theoretic quantities such as block entropy. An eflcient estimation procedure for the complexity measure is introduced. The estimarion is based on variable lengrh Markov chains and is using the well-known Shannon(More)
