Our engagement with consumer products diminishes gradually over the last decades, which causes considerable usability problems. To dissolve these problems, the designer's emph...
The synthesis theory for spatial linkage systems can be formulated in a way that is compatible with the geometric design of serial and parallel chain robotic systems. Mechanism de...
Location information can be used to enhance interaction with mobile devices. While many location systems require instrumentation of the environment, we present a system that allow...

Our approach to the spatial coordination problem relies on parametrized force fields. Through a quantitative comparison on a complex spatial coordination problem treated with a s...
One of the most important operations in spatial access needed systems are spatial joins. Using for processing such operations R-tree like structures is intensively studies now. Th...
