This paper proposes a novel algorithmic framework for an advanced virtual brush to be used in interactive digital painting. The framework comprises the following components: a geometry model of the brush using a hierarchical representation that leads to substantial savings in every step of the painting process; fast online brush motion simulation assisted by offline calibration that guarantees ...

We investigate the effect of linguistic complexity on cognitive load in a dual-task scenario, namely simultaneous driving and language use. To this end, we designed an experiment where participants use a driving simulator while listening to spoken stimuli and answering comprehension questions. Online physiological measures of cognitive load, including the recently established Index of Cognitive...

Computer games are increasingly used for purposes beyondmere entertainment, and current hi-tech simulators can provide quite, naturalistic contexts for purposes such as traffic education. One of the critical concerns in this area is the validity or transferability of acquired skills from a simulator to the real world context. In this paper, we present our work in which we compared driving in th...

to minimize renal radiation in abdomical radiotherapy, shielding of the kidneys is essential. ivp-simulator is used as an standard method. in this study, we used 99mtc-dmsa to localize and shield the kidneys and we compared this method with ivp-simulator. the size of the kidneys was proven to be larger as compared with ivp method. the mean of the overlap percentage was 81.88 in right and 82.89 ...
