Abstract
Fine operations exist in the form of teleoperation, human-machine cooperative work, and fine manual assembly. However, there is a lack of research that explores the characteristics of different assistive guidance methods and their use for fine operation tasks with different levels of difficulty. For this issue, this study first designed a prototype of a magnetic-based kinesthetic interaction device, and then using this device, a user study (n = 27) was designed and conducted. The experiment explored the performance of 2D and 3D visual cues as well as haptic cues when facing operation tasks with different levels of difficulty and analyzed the characteristics of each guidance modality and its reasons. The experimental results suggest that (1) visual cues are better suited than haptic cues to convey directional information in fine operations, (2) haptic cues can introduce an additional physical load, and (3) 2D visual cues’ missing depth information can affect operations in the view direction.
