Design and Evaluation of Visual Interpenetration Cues in Virtual Grasping

摘要: We present design and impact studies of visual feedback for virtual grasping. The suggest new or updated guidelines feedback. Recent grasping techniques incorporate cues to help resolve undesirable performance artifacts encountered after real fingers enter a object. Prior about such visuals are based largely on other interaction types provide inconsistent potentially-misleading information when applied address this with two-stage study. In the first stage, users adjusted parameters various types, including some novel aspects, identify promising settings give insight into preferences regarding parameters. next tuned were evaluated in terms objective (finger penetration, release time, precision) subjective rankings (visual quality, perceived behavior impact, overall preference). Additionally, subjects commented while reviewing them final session. Performancewise, most directly reveal penetrating hand configuration way. Subjectively, appreciated interpenetration grasp force, color changes promising. results enable selection best understanding relevant tradeoffs reasonable parameter values. also needed basis more focused specific choosing conditions comparisons modes, as haptic, audio, multimodal. Considering results, we propose that 3D must be capture importance cues, possible benefits direct representations, involved cue selection.
