We investigated how visual and kinaesthetic/efferent information is integrated for speed perception in running. Twelve moderately trained to trained subjects ran on a treadmill at three different speeds (8, 10, 12 km/h) in front of a moving virtual scene. They were asked to match the visual speed of the scene to their running speed–i.e., treadmill’s speed. For each trial, participants...

This paper compares an emergent interaction modality for the In-Vehicle Infotainment System (IVIS), i.e., gesturing on the steering wheel, with two more popular modalities in modern cars: touch and speech. We conducted a betweensubjects experiment with 20 participants for each modality to assess the interaction performance with the IVIS and the impact on the driving performance. Moreover, we...

Nowadays, the increasing complexity in government-related processes presents considerable challenges to achieve satisfactory services. In this study we will discuss the first results obtained in an ongoing project named “e-Government Innovation Center”. We first identify typical semantic problems in e-Government, then introduce an e-Government semantic business process management framework...
