One-Shot Evaluation of the Control Interface of a Robotic Arm by Non-experts

Abstract

Abstract. In this paper we study the relation between the performance of use and user preferences for a robotic arm control interface. We are interested in the user preference of non-experts after a one-shot evaluation of the interfaces on a test task. We also probe into the possible relation between user performance and individual factors. After a focus group study, we choose to compare the robotic arm joystick and a graphical user interface. Then, we studied the user performance and subjective evaluation of the interfaces during an experiment with the robot arm Jaco and N=23 healthy adults. Our preliminary results show that the user preference for a particular interface does not seem to depend on their performance in using it: for example, many users expressed their preference for the joystick while they were better performing with the graphical interface. Contrary to our expectations, this result does not seem to relate to the user's individual factors that we evaluated, namely desire for control and negative attitude towards robots.

Teleoperating a robot for removing asbestos tiles on roofs: insights from a pilot study

“…This means they preferred to be in direct teleoperation mode, rather than sending high-level commands to the robot through the interface or supervising the robot's autonomous activity. This result is in line with another experimental study we conducted in the past on a teleoperation setup with the Kinova Jaco arm [20], where we found that participants preferred to use joysticks than graphical interfaces even if they made more errors with the hand-held devices. Among the motivation for this preference, the participants reported that they felt more in control, they felt they could improve their performance over time (expected improvement), had fewer attention switches and could focus exclusively on the visual feedback (looking at the robot).…”

“…The concept of identifying the key points, the sequence and the repetition of operations was not intuitive for the construction workers; other participants (robotics engineers) familiar with those questions understood the principle but had issues when using the interface to configure the operations. We encountered similar issues as in [20], which means more attention switches and cognitive operations for the graphical interface, even if it could enable the operator to automatically perform certain operations without error, such as automatically aligning the robot forks to the roof tile.…”

Design and Analysis of a Wearable Upper Limb Rehabilitation Robot with Characteristics of Tension Mechanism

“…The number of young patients with functional impairment of the upper limbs caused by stroke has increased rapidly, as influenced by accelerated pace of life, poor lifestyles and environmental factors [1,2]. Limb movement disorder, which is caused by hemiplegia after stroke, not only reduces the quality of life of patients, but also brings great pain to their physiology and psychology.…”
