Judgments of passability help to quantify differences in perception between DLS and TO. These results will be useful in the design of training regimes for TO tasks. Increasing operator understanding of performance differences under varying conditions will lead them to be more accurate when making critical decisions in remote environments.
Introduction. This study investigated the relationship between spatial perception abilities and robot operation under direct-line-of-sight and teleoperation viewing conditions. This study was an effort to determine if spatial ability testing may be a useful tool in the selection of human-robot interaction (HRI) operators. Method. Participants completed eight cognitive measures and operated one of four types of robots under tasks of low and high difficulty. Performance for each participant was tested during both direct-line-of-sight and teleoperation. Results. Spatial abilities are shown to be reliable predictors of directline-of-sight and teleoperation performance. Participants in this study with higher spatial abilities completed their tasks faster and with fewer errors. Participants with higher spatial abilities were also more successful at completing the task. Discussion. Applications of these findings are discussed in terms of teleoperator selection tools, HRI training, and human-centered design recommendations.
Objective: To examine the effect of input device on performance of a driving task during uncoupled motion (UM). Background: Muth, Walker & Fiorello (2006) demonstrated that UM affected performance on a driving task with a steering wheel input device. However, it was unclear if the effect was due to general (motion sickness) or specific (interference with motor control) effects of UM. Methods: Ten participants completed a driving task while in a stationary and a moving real vehicle using a handheld control pad. Data were combined with the results of the previous study. Results: Regardless of input device, performance was significantly affected by UM, F(1,18) = 16.69, p< 0.01, ή p 2 =0.48. There was also a condition by input device interaction, F(1, 18) = 4.81, p<0.05, ή p 2 =0.21. Conclusions: This study demonstrated that UM can have both specific and general effects and that system design can potentially mitigate some of these effects.The main purpose of this study was to investigate whether the performance decrements demonstrated in Muth, Walker, and Fiorello's (2006) study were due to the general effects of motion sickness on the participants or the more specific effects of the vehicle motion on the driving task's input device.
