“…The interface × delay coefficient has a high p-value indicating that there was not a significant interaction between communication delay and interface. Decrease in area covered is consistent with the increased task completion times observed in Metcalfe et al (2010) with the steerable waypoint.…”

“…A steerable waypoint interface similar to that used in the military (Metcalfe et al, 2010) and with telepresence robots (Takayama et al, 2011) was tested in study 2. Performance metrics of area and collisions are summarized in Fig.…”

“…Another method to improve teleoperation performance has been through the use of different control interfaces. The idea of a steerable waypoint has been used in control of military robots (Metcalfe et al, 2010) and telepresence robots (Takayama et al, 2011). The idea behind the steerable waypoint is that the user can continuously update the location of a waypoint out ahead of the robot.…”

“…Safety features, such as obstacle avoidance, can be included in the controller that plans the path towards the waypoint location. Experimental results with the steerable waypoint method have often shown that while the number of errors might be reduced, task completion time often increases with the steerable waypoint (Metcalfe et al, 2010; Takayama et al, 2011).…”

Teleoperation allows human operators to safely extend themselves to remote environments that are typically difficult or dangerous to access. The remote environments are often unstructured (i.e. not having clear roads or paths to follow) and only accessible by wireless communication (introducing factors such as degraded signals and communication delay). Teleoperated driving under these conditions can result in slow operation speeds and unintended collisions with obstacles. Automating portions of the teleoperation task can help mitigate some of the negative effects of wireless communication. Shared control is used to combine inputs from the human teleoperator and automation. This work presents a new model predictive control based shared control method. We introduce a new representation for obstacle free regions that works well with unstructured robot environments and allows for an model predictive control problem formulation that can be solved rapidly. The shared control method is implemented in a robot simulator and tested with human subjects. Two user studies involving a search task with a mobile robot evaluate the effectiveness of the shared control method and explore its interaction with factors such as communication delay and input interface style. Communication delay is found to have the largest magnitude effect on performance and safety measures. Results demonstrate that the shared control method can improve both performance and safety when delays are present.

“…Autonomy should be granted to enable users to make decisions with freedom and maintain control in any enrolment process or any data usage involved in using technologies Persuasion should be based on prior user consent and offer as much autonomy as possible to the user (Spahn, 2011); Studies of human interactions with driving automation executed in an immersive, fullmotion simulated environment have observed a lack of trust in participants when they perceived they had insufficient control (Metcalfe et al, 2010); Data collection process in systems can be made intelligible to the users and modifiable or interruptible at their will (Jacucci et al, 2014).…”

Shared control versus traded control in driving: a debate around automation pitfalls

2022

A major question in human-automation interaction is whether tasks should be traded or shared between human and automation. This work presents reflections-which have evolved through classroom debates between the authors over the past 10 years-on these two forms of humanautomation interaction, with a focus on the automated driving domain. As in the lectures, we start with a historically informed survey of six pitfalls of automation: (1) Loss of situation and mode awareness, (2) Deskilling, (3) Unbalanced mental workload, (4) Behavioural adaptation, (5) Misuse, and (6) Disuse. Next, one of the authors explains why he believes that haptic shared control may remedy the pitfalls. Next, another author rebuts these arguments, arguing that traded control is the most promising way to improve road safety. This article ends with a common ground, explaining that shared and traded control outperform each other at medium and low environmental complexity, respectively. Practitioner summary: Designers of automation systems will have to consider whether humans and automation should perform tasks alternately or simultaneously. The present article provides an in-depth reflection on this dilemma, which may prove insightful and help guide design.
