, to the best of our knowledge, the unique validated model for respiratory computation, it appears to be affected by some weaknesses: (i) it cannot be used in other motion capture systems; (ii) extra virtual markers are required to close the chest wall surface and calculate respiratory volumes (leading

% MVC on the monitor during CT by resisting virtual perturbation of a 0.2-Hz sinusoidal signal (Figure  1 , the lower plot). Being blinded to the virtual perturbation that deviated force output, the participants had to carefully monitor the tracking mismatch at every moment. Actually, the participants

cluster was used to determine the locations of the second metatarsal head and the distal end of the shoe during the movement trials, using a modification of the virtual marker representation outlined by Nagano et al. 11 Based on the assumption that the shoe is rigid during the swing phase, particularly

through state and district virtual schools ( Gemin et al., 2015 ). In the 2015–2016 school year, over two million K-12 students took online courses and completed over four million courses ( Gemin & Pape, 2016 ). Hundreds of thousands of K-12 students attend full-time online schools, and many students are

how the errors are reduced while performing the task under these new conditions. Examples of experimental modifications of task conditions are visual distortion or virtual force fields ( Blanchette & Bouyer, 2009 ; Inui & Hatta, 2002 ; Krakauer & Mazzoni, 2011 ; Lackner & DiZio, 2005 ; Shadmehr

Social media’s role as a virtual water cooler has been well established ( Shirky, 2008 ), particularly for sport fans ( Sanderson, 2011 ). Social networks have been hailed for their ability to influence society ( Benhabib, 2011 ; Castells, 2012 ). There has also been criticism of social media

force and angle of contact between virtual hand and ball influences the direction of the ball’s rebound, which signifies the role of cognition on action and thus, its influence on object-manipulation competence ( Rosenbaum, Chapman, Weigelt, Weiss, & van der We, 2012 ). As a whole, the omega

60-s time window. TtC = time-to-contact; CoP = foot center of pressure. TtC Calculation The TtC was calculated by determining a position vector of the CoP on a virtual trajectory for each moment in time ( t ) based on the instantaneous CoP position, velocity, and acceleration ( Haddad et al., 2006
