Haptic Rotary Knob
|
This is the prototype haptic dial with slip available to the user at the index finger. We render shear, vibration, and gross slip with the inner surface in conjunction with the force feedback from the dial for a wide range of interesting and informative sensations. |
In addition to experimental testing, we are pursuing several applications of fingertip haptics that involve adding the sensation of slip to conventional haptic feedback devices. Pictured on the left is a prototype haptic feedback dial that has a small window for the user's index finger. We control a separate surface just beneath the window to render slip at the fingertip. In this configuration, slip acts as an additional mode of information to the user, supplementing the kinesthetic sensations delivered by the dial itself. |
| The
eventual goal is to mount this or a similar device at the end of a conventional kinesthetic haptic device - one capable of larger translational movements and feedback. Adding slip and other tactile sensations to conventional haptic devices begins to reproduce the real-world interaction between the hand and an object. Furthermore, we are finding that the tactile sensations themselves may serve as modes of information, apart from just delivering realistic surface characteristics. |
In one mode of use, the user places his or her finger on the window and moves back and forth while feeling slip. |
