论文摘要
3-5级自动驾驶汽车（APMV）和汽车的乘客（驱动程序）可以在开车时执行非驾驶任务，例如阅读书籍和智能手机。已经指出，这种活动可能会增加运动疾病。已经进行了许多研究来建立对策，其中已经开发了各种计算运动模型。其中许多是基于主观垂直冲突（SVC）理论，该理论描述了人类感觉器官与中枢神经系统所期望的方向的垂直变化。预计此类模型将应用于自动驾驶场景。但是，没有当前的计算模型可以将视觉垂直信息与前庭感觉整合在一起。 我们提出了一个6 DOF SVC-VV模型，该模型将视觉感知的垂直块添加到传统的六度SVC模型中，以从模拟人类的视觉输入的图像数据中预测VV方向。因此，提出了一种简单的基于图像的VV估计方法。 作为对拟议模型的验证，本文的重点是描述当乘客在使用AMPV时读书时，运动疾病会增加，假设视觉垂直（VV）起着重要作用。在静态实验中，证明通过所提出的方法估计的VV准确地描述了平均绝对偏差低的重力加速度方向。此外，使用APMV的驾驶实验的结果表明，提出的6 DOF SVC-VV模型可以描述当VV和重力加速度方向不同时经历的疾病增加。
Passengers (drivers) of level 3-5 autonomous personal mobility vehicles (APMV) and cars can perform non-driving tasks, such as reading books and smartphones, while driving. It has been pointed out that such activities may increase motion sickness. Many studies have been conducted to build countermeasures, of which various computational motion sickness models have been developed. Many of these are based on subjective vertical conflict (SVC) theory, which describes vertical changes in direction sensed by human sensory organs vs. those expected by the central nervous system. Such models are expected to be applied to autonomous driving scenarios. However, no current computational model can integrate visual vertical information with vestibular sensations. We proposed a 6 DoF SVC-VV model which add a visually perceived vertical block into a conventional six-degrees-of-freedom SVC model to predict VV directions from image data simulating the visual input of a human. Hence, a simple image-based VV estimation method is proposed. As the validation of the proposed model, this paper focuses on describing the fact that the motion sickness increases as a passenger reads a book while using an AMPV, assuming that visual vertical (VV) plays an important role. In the static experiment, it is demonstrated that the estimated VV by the proposed method accurately described the gravitational acceleration direction with a low mean absolute deviation. In addition, the results of the driving experiment using an APMV demonstrated that the proposed 6 DoF SVC-VV model could describe that the increased motion sickness experienced when the VV and gravitational acceleration directions were different.
