Abstract
A haptic system includes a haptic ring that is worn on the finger of a user. The haptic ring includes a flexible tube that is positioned against the finger pad of the user and configured to transport a fluid across the finger pad of the user. A first pump is configured to pump a warm fluid into the flexible tube and a second pump is configured to pump a cold fluid into the flexible tube, thereby providing a haptic sensation of temperature. A valve is positioned downstream of the haptic ring that is configured to open and close to modulate the pressure of the fluid, thereby providing a haptic sensation of pressure and/or vibration to the finger pad of the user. The haptic ring is unobtrusive and therefore does not significantly interfere with the ability of the user to perceive tactile sensations of the real world.
