摘要: Previous work has shown that virtual fixtures applied to cooperative manipulation systems improve performance in tracking tasks. However, if a user wishes move away from the nominal path, stiffness of fixture should be adjusted increase level control. Our experiments show modifying soft can user's performance, measured by position error and execution time, for task where targets point off path. Three methods changing were tested: on/off toggle, linear fade, constant force hold. In addition, we considered three activating change: explicit, implicit, automatic. User trials revealed several combinations scaling activation significantly reduced errors when compared no adjustment.
