Where's my TOR?: Evaluating the Effect of Take-Over Request Source on Older Driver's Control Transition in Level 3 Cars

Transitioning to manual control after a Take-Over Request (TOR) is issued by a Level 3 car presents challenges for older drivers. This study investigates if the presentation source of the TOR affects driver performance when resuming control. We measure take-over performance, hazard perception, and user acceptance when…

Reality Anchors: Bringing Cues from Reality to Increase Acceptance of Immersive Technologies in Transit

Immersive technologies allow us to control and customise how we experience reality, but are not widely used in transit due to safety, social acceptability, and comfort barriers. We propose that cues from reality can create reference points in virtuality, which we call Reality Anchors, will reduce these barriers. We us…

Using VR While Travelling: Manipulating the Orientation of Planar 2D Content in VR as an Implicit Visual Cue for Mitigating Passenger Motion Sickness

The use of Virtual Reality technology in vehicles is poised to bring about a new era of transport experiences, but its use can cause or enhance motion sickness. However, with careful design, VR devices have the potential to mitigate motion sickness and provide immersive experiences while travelling. We propose a novel…

AUTO_UI '23CorrespondingExternal HMI (eHMI) — Communication with Pedestrians & Cyclists

Pimp My Ride: Designing Versatile eHMIs for Cyclists

Autonomous vehicles (AVs) must communicate their intentions to nearby road users and may use external Human-Machine Interfaces (eHMIs). Most eHMIs have focused on interaction with pedestrians at crossings. However, these may not work for cyclists, who can be anywhere around vehicles and encounter them in diverse traff…

PassengXR: A Low Cost Platform for Any-Car, Multi-User, Motion-Based Passenger XR Experiences

We present PassengXR, an open-source toolkit for creating passenger eXtended Reality (XR) experiences in Unity. XR allows travellers to move beyond the physical limitations of in-vehicle displays, rendering immersive virtual content based on - or ignoring - vehicle motion. There are considerable technical challenges t…

Acoustic Transparency and the Changing Soundscape of Auditory Mixed Reality

Auditory headsets capable of actively or passively intermixing both real and virtual sounds are in-part acoustically transparent. This paper explores the consequences of acoustic transparency, both on the perception of virtual audio content, given the presence of a real-world auditory backdrop, and more broadly in fac…

Exploring the Concept of the (Future) Mobile Office

This video shows a concept of a future mobile office in a semi-automated vehicle that uses augmented reality. People perform non-driving tasks in current, non-automated vehicles even though that is unsafe. Moreover, even for passengers there is limited space, it is not social, and there can be motion sickness. In futu…

Haptic Navigation Cues on the Steering Wheel

Haptic feedback is used in cars to reduce visual inattention. While tactile feedback like vibration can be influenced by the car's movement, thermal and cutaneous push feedback should be independent of such interference. This paper presents two driving simulator studies investigating novel tactile feedback on the stee…

May the Force Be with You: Ultrasound Haptic Feedback for Mid-Air Gesture Interaction in Cars

The use of ultrasound haptic feedback for mid-air gestures in cars has been proposed to provide a sense of control over the user's intended actions and to add touch to a touchless interaction. However, the impact of ultrasound feedback to the gesturing hand regarding lane deviation, eyes-off-the-road time (EORT) and p…

Investigation of Thermal Stimuli for Lane Changes

Haptic feedback has been widely studied for in-car interactions. However, most of this research has used vibrotactile cues. This paper presents two studies that examine novel thermal feedback for navigation during simulated driving for a lane change task. In the first, we compare the distraction and time differences o…
