The Witty SEM system was used along with a h/p/cosmos treadmill in order to perform research about dual tasking. In detail the Witty SEMs were mounted with claps to the treadmill. Subjects were walking at different speeds, while performing diverse tasks on the Witty SEM. Resulting training regimes were progressed from easy to difficult. Witty SEM offered plenty possibilities to focus the attention, but also the treadmill supports various movement pattern - forward, backward, sidesteps, uphill, downhill, slow to fast.
