Control behavior in simulation


By measuring control behavior in simulation, we increase our understanding of the relationship between motion perception and action. By measuring control performance and behavior, we can infer knowledge on the effect of the simulated stimuli. For example, we investigate how motion feedback can aid operators in the tele-operation of vehicles.

Teleoperation

Teleoperating a vehicle (i.e., controlling a vehicle from a remote location) is a challenging task due to the limitations in on-board sensing, data transmission, and the presentation of relevant information to the operator. These issues lead to a decrease in "situational awareness", causing poor performance or accidents. We investigate whether the overall situational awareness can be increased by providing motion feedback to the operator. What differentiates using motion feedback in teleoperation tasks from vehicle simulation (e.g., for aircraft pilot training purposes) is that in the former the motion feedback does not necessarily need to be a faithful reproduction of the vehicle's motion. In fact, by "shaping" the motion feedback,  based on the task and constraints, the situational awareness could be further increased.
 
In our experiments participants complete different teleoperation tasks and we vary the type of motion feedback while measuring the performance and the control effort. We found that vehicle-state motion feedback (i.e., motion feedback related to the motion state of the vehicle) improves performance. The results showed furthermore that task-related motion feedback (i.e., motion feedback related to the task performance) increases performance compared to no-motion conditions.
 
In the video below, an octorotor is teleoperated from inside the MPI CyberMotion Simulator, while the pilot is exposed to motion feedback.
 
 

Vehicle simulation

In driving simulation, simulator tilt is used to reproduce linear acceleration. In order to feel realistic, this tilt is performed at a rate below the tilt-rate detection threshold, which is usually assumed constant. However, it is known that many factors affect the threshold, like visual information, simulator motion in additional directions, or active vehicle control. We investigated the effect of these factors on roll-rate detection threshold during simulated curve driving.
 
Participants reported whether they detected roll in multiple trials on a driving simulator. Roll-rate detection thresholds were measured under four conditions. In the first three condition, participants were moved passively through a curve with: (i) roll only in darkness; (ii) combined roll/sway in darkness; (iii) combined roll/sway and visual information. In the fourth condition participants actively drove through the curve.
 
Results showed that roll-rate perception in vehicle simulation is affected by the presence of motion in additional directions. Moreover, an active control task seems to increase the detection threshold, i.e. impair motion sensitivity, but with large individual differences. We hypothesize that this is related to the level of immersion during the task.
