Abstract
Present BCI research suggests that it is possible to control a computer by the brain on two separate dimensions. As trajectory formation as found for instance in handwriting is also a 2-dimensional control task, we try to find out if the separation between different dimensions in the 2D trajectory formation can be learned.
Therefore, we constructed a platform which facilitates the research of learning effects in the production of 2-dimensional trajectories. The platforms' ability to facilitate learning this task includes a 1 person, a 2 person and a HCI setting. The 1 person and 2 person conditions have been explored in a previous study, in which the platform has proven to be very successful. The aim of the present research is to find if the ability
to separate between movement dimensions can be learned in a HCI setting. We are also interested to find if the behavior of the computer influences the users' ability to learn this task when interacting with a computer.
Results of these studies indicate that participants could indeed separate the movement dimensions and that there are suggestions that the behavior of the computer influences this ability. A more cooperative computer could help to create more accurate and more
fluent trajectory formation. Findings in this research might transfer to the BCI domain, where the learning of a 2-dimensional task could benefit from the interaction
with a computer.
