Two approaches to the study of movement planning were contrasted. Data on the drawing of complex two-dimensional trajectories were used to test whether the covariations of the kinematic and geometrical parameters of the movement formalized by the two-thirds power law and by the isochrony principle (P. Viviani & R. Schneider, 1991) can be derived from the minimum-jerk model hypothesis (T. Flash ...

Three members of the same family with hereditary congenital nystagmus (eN) were studied. Nystagmus amplitude, fre­ quency, and Intensity functions deter­ mined the gaze angle with least nys­ tagmus. Visual acuity was increased in all cases by the use of version or composite prisms. In both pendular and jerk forms of eN, the fovea oscillated on alternate sides of the fixation spot and exhibited ...

Both path and speed planning play key roles in automated driving, specially when a certain comfort level is required. This paper proposes human-like method for already defined paths while minimizing travel time. The proposed able to compute time-optimal profile that meet the given constrains with regard speed, acceleration jerk. For this purpose, an initial acceleration-limited approach introdu...

Feedrate scheduling is one of the most critical technologies in CNC machining, requiring a reasonable balance between efficiency and quality. This paper proposes jerk-continuous feedrate smoothing (JCFS) method to generate low-vibration smooth profile for non-uniform rational B-spline (NURBS) interpolation. Firstly, segmentation concept introduced subdivide entire trajectory into segments accom...
