The difficulty of remotely negotiating corners

Positioning Graphical Objects on Computer Screens

“…Remotely navigating robots through a hallway is another example. Pastel, Champlin, et al (2007) studied the difficulty in negotiating a virtual hovercraft through corners in hallways of various widths ( w ) using standard keyboard inputs. Because navigating the craft through the straight hallway sections could be automated and was relatively easy even for inexperienced participants, the study concentrated on negotiating only the corners of the hallways.…”

Cornering Law

“…Our results demonstrated that the cornering law was successful at predicting performance for this viewing angle. More importantly, it showed that the cornering law is not specific to third-person trailing view as used in Pastel et al (2007). However, neither third-person views (overhead or third-person trailing) are typically used in UGV operations.…”

“…The cornering law has been applied to virtual environments (Pastel et al, 2007). Pastel and colleagues (2007) developed the cornering law and applied it to a virtual computer simulation in which participants piloted a virtual vehicle through various corners that varied in difficulty as a function of aperture width.…”

The Difficulty of Centering Circular Discs

“…However, the linear model for the mean TT binned by A (65 bins with approximately 1000 data points for each bin) has even a higher correlation, r 2 = 0.99, Figure 5, and shows no residual trend. Pastel et al (2007) demonstrated centering in a different context, negotiating a virtual hover craft through a virtual hallway with a corner. In their experiments centering time was measured as the time to negotiate the hovercraft through the corner.…”
