Furthermore, the work presented in this paper focuses on the assessment of
Kinect's capabilities for perform the CSRT test. This study aims to find out whether
the limitation imposed by the frame rate is determinant when collecting time-based
measurements associated to human movements. The following section sets out the
methodology used for this evaluation.

Methodology
A convenient sample of 10 individuals was recruited. Participants consisted of
research students and lecturers from the University Technology Sydney. The
eligibility criteria are described as follows: (1) Not contributed to the design of these
instruments. (2) Able to walk independently without assistance, and (3) Fluent in the
English language.
Participants were asked to perform the CSRT test on both systems. The order was
randomized to counterbalance order effects. Prior to testing on the Kinect, each
participant went through a calibration process in order to determine the proper floor
