Haptic Handle

A grip on a mobility or guidance device (robot, smart cane, haptic rein, etc.) that conveys information to the user through touch — typically via buttons, vibrotactile feedback, or physical coupling to the device's motion. On suitcase-shaped navigation robots for blind users, a haptic handle provides directional buttons for starting, stopping, and changing speed, plus a touch sensor so the robot only moves while the user is holding on. The handle design matters for accessibility because it is the user's primary channel for controlling and understanding the robot's state without vision.
