In the case of the introduction of a new system, not only evaluation of the function but also evaluation of emotional and cognitive load caused by the use is important. Considering the psychological state is originated in brain, we assume that both emotional and cognitive state can be discerned from brain activity using fMRI. In this study, we evaluated an in-car video assist system which could provide information about oncoming traffic when a driver’s view was occluded. When the view was occluded, the system reduced activity in regions involved with anxiety but increased activity in regions involved with visual processing. The results indicated that the system would reduce anxiety level of drivers but increase visual load. These results could not be speculated solely by behavioral measurements. This study suggests a new application of fMRI as a system evaluation tool. |
