N2  - This paper shows a technique for evaluation of the in-car device placement design. Bidirectional primary-secondary task method is introduced to evaluate both of the driving performance during the in-car device operation and the in-car device operation performance during the driving. While the operation performance is evaluated easily based on the success rate of the device operation and so on, the driving performance is evaluated based on the index of the decision making ability of the driver. This index is quantified as the entropy by utilizing the Probability weighted ARX model. The position of the operating device is evaluated in the proposed evaluation framework. Primary task is the vehicle following task and the secondary task is the panel touching task. Driving data are collected on a driving simulator and a mathematical model of driving behavior is identified using each set of data. By calculating the model entropy of PrARX models and the success rate of the device operation, one can evaluate the influence of each device operation on the driver's decision-making ability in a quantitative manner.<p /> <p>Language: ja</p>
