Identifying the role of proprioception in upper-limb prosthesis control: Studies on targeted motion
Amy Blank, Allison M. Okamura, Katherine J. Kuchenbecker
Article No.: 15
Proprioception plays a crucial role in enabling humans to move purposively and interact with their physical surroundings. Current technology in upper-limb prostheses, while beginning to incorporate some haptic feedback, does not provide amputees...
Evaluating the multivariate visual quality performance of image-processing components
Jenni Radun, Tuomas Leisti, Toni Virtanen, Jukka Häkkinen, Tero Vuori, Göte Nyman
Article No.: 16
The estimation of image quality is a demanding task, especially when estimating different high-quality imaging products or their components. The challenge is the multivariate nature of image quality as well as the need to use naïve observers...
“Writing with music”: Exploring the use of auditory feedback in gesture interfaces
Tue Haste Andersen, Shumin Zhai
Article No.: 17
We investigate the use of auditory feedback in pen-gesture interfaces in a series of informal and formal experiments. Initial iterative exploration showed that gaining performance advantage with auditory feedback was possible using absolute cues...
We examined the eye movements of pilots as they carried out simulated aircraft landings under day and night lighting conditions. Our five students and five certified pilots were instructed to quickly achieve and then maintain a constant 3-degree...
Evaluating 2D and 3D visualizations of spatiotemporal information
Andreas Kjellin, Lars Winkler Pettersson, Stefan Seipel, Mats Lind
Article No.: 19
Time-varying geospatial data presents some specific challenges for visualization. Here, we report the results of three experiments aiming at evaluating the relative efficiency of three existing visualization techniques for a class of such data....
It has been previously proposed that understanding the mechanisms of contour perception can provide a theory for why some flow rendering methods allow for better judgments of advection pathways than others. In this article, we develop this theory...
