Abstract

The Leap Motion Controller (LMC) is a hand-held, non-professional motion capture device that is able to evaluate different motor tasks in a clinical s etting. In this study, its accuracy was verified, evaluating its performance in the acquisition of movements based on the simulation of the Archimedean spiral test. We present an innovative method for obtaining information on fine m otor s kills d uring t he s piral d rawing t est, u sing a n instrumented evaluation platform based on the LMC. First, several experimental conditions were carried out that challenged the performance of the LMC during the simulation of the spiral test, then a case study was conducted to establish the validity of its use to evaluate the spiral drawing test in humans. Due to this research it is possible to extrapolate the spiral drawing test from a two-dimensional space to a three-dimensional space, without restrictions, or contact with objects and in a controlled clinical environment. Allowing to obtain variables of the kinematics of the hand during a spiral drawing task in a three-dimensional space in future. © 2023 SPIE.
