HMI for elderly drivers in an off-vehicle parking assistance system

We have studied HMI for driving instructions for an off-vehicle parking assistance system and reported experiments for evaluating it by elderly driver. This paper proposes comprehensive human machine interfaces (HMI) between a communication-based guidance system and an elderly driver for providing vehicle control instructions, and describes the experimental studies performed for the system evaluation. We studied on three ways of issuing instructions through an HMI using W-LAN, which were proposed and evaluated while experiments by young drivers. The new HMI for issuing instructions through the car audio was evaluated with experiment by young drivers. This paper describes the study on the HMI for elderly drivers and evaluation with 18 elderly drivers. The result shows that, it was possible for an elderly driver to drive a vehicle to a parking space using the proposed method, and the acceptability and validity of the system as off-vehicle guidance system were also proved.
