摘要：

A dual-mode cane includes a tip. The tip includes a low-friction surface that contacts a walking surface when the tip rests on the walking surface at an angle less than or equal to a transition angle. The tip includes a high-friction surface that contacts the walking surface when the tip rests on the walking surface at an angle greater than or equal to the transition angle.
