Four major contributions of this paper include:

• Provides insight of the effects of different kinematics (e.g., straight, simple, *legible*)
• Focuses mainly on the performance and quality of Human-Robot collaboration, differentiating from highlighting only the functional objectives (e.g., minimizing time, maximizing efficiency)
• Entails various evaluation metrics that measure both absolute and relative time (or path it took) for the user to correctly predict robot intent
• Guides future research to investigate factors that shape observer performance (e.g., participant's vantage point, robot degree-of-freedom)
