Spectrum of power laws for curved hand movements.
In a planar free-hand drawing of an ellipse, the speed of movement is proportional to the -1/3 power of the local curvature, which is widely thought to hold for general curved shapes. We investigated this phenomenon for general curved hand movements by analyzing an optimal control model that maximizes a smoothness cost and exhibits the -1/3 power for ellipses. For the analysis, we introduced a ...

15 صفحه اولInherent structure of manipulative hand movements and its discriminative power
Understanding the inherent structure of manipulative hand movements is a critical step toward automatic recognition of manipulative hand movements and toward automatic planning of natural movements for dexterous robots. Manipulative hand movements involve coordinated movements of the digits to manipulate an object within the hand, and are classified as either simultaneous or sequential. Simulta...
متن کاملHand Movements
The human hand and the brain are close partners in two important and closely interconnected functions: exploration of the physical world and reshaping of parts of this world through manipulation. The highly versatile functions of the human hand depend on both its anatomical structure and the neural machinery that supports the hand. This article focuses on the sensorimotor control of hand moveme...
متن کاملPower Laws and the Cosmic Ray Energy Spectrum
Two separate statistical tests are applied to the AGASA and preliminary Auger Cosmic Ray Energy spectra in an attempt to find deviation from a pure power-law. The first test is constructed from the probability distribution for the maximum event of a sample drawn from a power-law. The second employs the TP-statistic, a function defined to deviate from zero when the sample deviates from the power...
