Is Silent eHMI Enough? A Passenger-Centric Study on Effective eHMI for Autonomous Personal Mobility Vehicles in the Field
Hailong Liu, Yang Li, Zhe Zeng +3
Autonomous Personal Mobility Vehicle (APMV) is a miniaturized autonomous vehicle designed to provide short-distance mobility to everyone in pedestrian-rich environments. By the cha…
Pre-instruction for Pedestrians Interacting Autonomous Vehicles with an eHMI: Effects on Their Psychology and Walking Behavior
Hailong Liu, Takatsugu Hirayama
External human-machine interface (eHMI) is considered as a new explicit communication method for pedestrian-AV interactions, particularly in encounter scenarios. Pedestrians withou…
Subjective Vertical Conflict Model with Visual Vertical: Predicting Motion Sickness on Autonomous Personal Mobility Vehicles
Hailong Liu, Shota Inoue, Takahiro Wada
Passengers of level 3-5 autonomous personal mobility vehicles (APMV) can perform non-driving tasks, such as reading books and smartphones, while driving. It has been pointed out th…
Motion Sickness Modeling with Visual Vertical Estimation and Its Application to Autonomous Personal Mobility Vehicles
Hailong Liu, Shota Inoue, Takahiro Wada
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…
GaVe: A Webcam-Based Gaze Vending Interface Using One-Point Calibration
Zhe Zeng, Sai Liu, Hao Cheng +4
Even before the Covid-19 pandemic, beneficial use cases for hygienic, touchless human-machine interaction have been explored. Gaze input, i.e., information input via eye-movements…
Interaction Detection Between Vehicles and Vulnerable Road Users: A Deep Generative Approach with Attention
Hao Cheng, Li Feng, Hailong Liu +3
Intersections where vehicles are permitted to turn and interact with vulnerable road users (VRUs) like pedestrians and cyclists are among some of the most challenging locations for…
Autonomous Vehicles Drive into Shared Spaces: eHMI Design Concept Focusing on Vulnerable Road Users
Yang Li, Hao Cheng, Zhe Zeng +2
In comparison to conventional traffic designs, shared spaces promote a more pleasant urban environment with slower motorized movement, smoother traffic, and less congestion. In the…
Importance of Instruction for Pedestrian-Automated Driving Vehicle Interaction with an External Human Machine Interface: Effects on Pedestrians' Situation Awareness, Trust, Perceived Risks and Decision Making
Hailong Liu, Takatsugu Hirayama, Masaya Watanabe
Compared to a manual driving vehicle (MV), an automated driving vehicle lacks a way to communicate with the pedestrian through the driver when it interacts with the pedestrian beca…
What Timing for an Automated Vehicle to Make Pedestrians Understand Its Driving Intentions for Improving Their Perception of Safety?
Hailong Liu, Takatsugu Hirayama, Luis Yoichi Morales +1
Although automated driving systems have been used frequently, they are still unpopular in society. To increase the popularity of automated vehicles (AVs), assisting pedestrians to…
What Is the Gaze Behavior of Pedestrians in Interactions with an Automated Vehicle When They Do Not Understand Its Intentions?
Hailong Liu, Takatsugu Hirayama, Luis Yoichi Morales +1
Interactions between pedestrians and automated vehicles (AVs) will increase significantly with the popularity of AV. However, pedestrians often have not enough trust on the AVs , p…
Explicit behaviors affected by driver's trust in a driving automation system
Hailong Liu, Toshihiro Hiraoka, Seiya Tanaka
As various driving automation system (DAS) are commonly used in the vehicle, the over-trust in the DAS may put the driver in the risk. In order to prevent the over-trust while driv…
Saliency difference based objective evaluation method for a superimposed screen of the HUD with various background
Hailong Liu, Toshihiro Hiraoka, Takatsugu Hirayama +1
The head-up display (HUD) is an emerging device which can project information on a transparent screen. The HUD has been used in airplanes and vehicles, and it is usually placed in…
Driving behavior model considering driver's over-trust in driving automation system
Hailong Liu, Toshihiro Hiraoka
Levels one to three of driving automation systems~(DAS) are spreading fast. However, as the DAS functions become more and more sophisticated, not only the driver's driving skills w…
