Driving is a complex and cognitively demanding task. It is important to assess the cognitive state of the driver in order to develop cognitive technical systems that can adapt to different cognitive states of the driver. For this purpose, we have de-veloped a mobile functional near-infrared spectroscopy (mofNIRS) prototype. This paper describes the improvements of this mobile prototype with freely placeable optodes on a subject's head and the results of an evaluation study. We conducted a motor cortex experiment with four subjects, whereby the mobile pro-totype was mounted on the right hemisphere and a commercial, stationary fNIRS on the left hemisphere above the motor cortex area. One data set had to be dis-carded due to incorrect synchronization between both systems. The results of the remaining three subjects are presented and discussed in this paper. Here, we re-port the results from the time-series and Statistical Parametric Mapping (SPM) analyses, which shows t-values with high differentiability of the Results. Fur-thermore, both analysis methods show comparable results between the commer-cial system and the mobile prototype.
