Study of HMI in Automotive ~ Car Design Proposal with Usage by the Elderly ~ 

Abstract

There are several issues specific to the elderly that exist in automobiles that support the mobility of the elderly in the community. Among these, this study focuses on the problem of getting in and out of automobiles due to changes in physicality. Due to physical changes caused by aging, there are situations that cannot be handled with the current door geometry. Considering the current situation in which automobiles have obstacles at the beginning and end of movement, and movement itself is considered an obstacle, we believe that the design of doors that allow people to get in and out without physical burden, as an interface (HMI) between the elderly and automobiles, is important not only for solving the problem of getting in and out, but also for automobile design in the era of autonomous driving. We believe this is important not only for solving the problem of getting in and out of the car, but also for automobile design in the era of autonomous driving. In addition, by targeting rural areas, it is expected to solve mobility problems in rural areas and improve the quality of life (QOL) of the elderly in rural areas. As a result of this study, we proposed a UX based on boarding/exiting and door shape, and established a new icon design based on door shape. Such an approach is expected to be effective in future automobile design.
