Our overall vision is to enable researchers to explore 3D datasets with as much immersion as possible, arising both from visuals as well as from interaction . We therefore explore ways to combine an immersive large view of the 3D data with means to intuitively control this view with touch input on a separate mobile monoscopic tablet. This combination has the potential to increase people's acceptance of stereoscopic environments for 3D data visualization since--through touch-based interaction--it puts them in control of their data. Moreover, the indirect manipulation of (stereoscopically displayed) 3D data on a personal touch device has been shown to have potentially more efficient and precise interaction than interaction directly on a large display.
