Our goal is to promote brain health through “bSports” (brain-Sports), a form of social sport competition using brain-machine interfaces. As the core technology, we have been developing an electroencephalography-based cognitive training system, “Neurotrainer,” event-related potential as virtual “mind switch” control games. Here, aimed assess performance Neurotrainer under competitive conditions ...

In a virtual point-to-origin task, participants seem to show different response patterns and underlying strategies for orientation, such as "turner" and "non-turner" response patterns. Turners respond as if succeeding to update simulated heading changes, and non-turners respond as if failing to update their heading, resulting in left-right hemisphere errors. We present two other response patter...

This paper is composed of two parts dealing with the modeling of environmental phenomena. The first part presents the traditional ER and OO formalisms dedicated to geographic information modeling. These languages focus mainly on representing the spatial and temporal properties of this type of information. Many of these languages express these properties visually by using pictograms. After a qui...
