Under that condition, the error in direction is rarely greater than ten degrees.
To test whether the individual participants made consistent and systematic errors in perceived direction, we used one-sample t-tests with the Šidák correction for multiple comparisons to assess whether the error in perceived direction was different from zero (i.e., no error) for each participant and head position separately.
As the subject head shapes were quite different, in some brain regions the co-registered error directions differed, thus partly cancelling each other in the mean error images.
The above errors are the key errors in the DAD process, in which only the errors in the sensitive direction will be considered, i.e., the errors in Z direction in this case.
Table 9 shows that the error in the Y direction (front and back of the cart) is significantly greater than the error of the X direction (left and right of the cart).
Data reduction and statistics The error in perceived direction (in degrees) was defined as the angle between the direction of the pointer and the direction of the true line between the ball and the hole (i.e., perfect aim line).
They showed that a different measure of the group velocity error must be used to account for the error in the propagation direction of the waves.
This saccade was identified using a predetermined algorithm based on pilot work; any saccade that included a blink, started before the target appears, started more than 2.5° from the central fixation point, or was in the wrong direction (error in angle of more than 45°) was removed.
The positive error indicates error in the CCW direction.
The error in the other direction is far more dangerous".
Moreover, trajectory assistance decreased the error in the depth direction, which was higher for manual control.
