We discuss touch-based navigation of 3D visualizations in a combined monoscopic and stereoscopic viewing environment. We identify a set of interaction modes, and a workflow that helps users transition between these modes to improve their interaction experience. In our discussion we analyze, in particular, the control-display space mapping between the different reference frames of the stereoscopic and monoscopic displays. We show how this mapping supports interactive data exploration, but may also lead to conflicts between the stereoscopic and monoscopic views due to users' movement in space; we resolve these problems through synchronization. To support our discussion, we present results from an exploratory observational evaluation with domain experts in fluid mechanics and structural biology. These experts explored domain-specific datasets using variations of a system that embodies the interaction modes and workflows; we report on their interactions and qualitative feedback on the system and its workflow.
This paper proposes the hybridization between two types of videogames (VG) that can be complementary in motor restoration tasks: the VG based on motion capture systems and the VG based on brain computer interfaces. This hybrid system allow the interaction inside of a VG created for the rehabilitation of standing balance in hemiparetic stroke patients through of movements and modulated mental intentions. The Brain Kinect Interface (BKI) is shown as a tool not only for improve the immersivity in serious VG for health, but as an instrumental arrangement for recording and analyzing of motion capture signals and electroencephalographic (EEG) signals recorded from the low cost sensors in order to improve the objectivity in analyzing motor recovery process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
