TL;DR: In this paper, a haptic feedback interface device using electroactive polymer actuators is described, including direct forces, inertial forces, and braking forces, which provide haptic sensation to the user.
Abstract: Haptic feedback interface devices using electroactive polymer (EAP) actuators to provide haptic sensations and/or sensing capabilities. A haptic feedback interface device (12) is in communication with a host computer (14) and includes a sensor (112) device that detects the manipulation of the interface device by the user and an electroactive polymer actuator (18) responsive to input signals and operative to output a force to the user cause by motion of the actuator. The output force provides a haptic sensation to the user. Various embodiments of interface devices employing EAP actuators are described, including embodiments providing direct forces, inertial forces, and braking forces.

TL;DR: In this paper, a method for haptic sculpting of a physical object using a haptic device is described, where the haptic cues are used to guide a user of the medical device in sculpting at least a portion of the physical object.
Abstract: In accordance with an embodiment of the present invention, a method for haptic sculpting of a physical object using a haptic device comprises defining a haptic object for aiding in the sculpting of the physical object, dynamically modifying a configuration of the haptic object in response to a medical device coupled to the haptic device being in proximity to the haptic object, and providing haptic cues to guide a user of the medical device in sculpting at least a portion of the physical object corresponding to the haptic object.

TL;DR: In this article, a display section with a touch screen is adapted to display at least one graphical user interface object and detect a touch position on the touch screen, and a pressure sensing unit is used to detect pressure applied to the screen.
Abstract: An apparatus includes a display section with a touch screen, and the touch screen is adapted to display at least one graphical user interface object and detect a touch position on the touch screen. The apparatus has a haptic feedback generating unit attached to the touch screen and is adapted to generating haptic feedback. A pressure sensing unit is attached to the touch screen and adapted to detect pressure applied to the touch screen. A controller section is adapted to control and drive the display section. The graphical user interface object displayed on the touch screen has a plurality of logical states. The controller section determines a current logical state of the graphical user interface object and a form of the haptic feedback to be generated depending on the detected touch position.

TL;DR: In this article, the authors describe haptic sensations for a haptic feedback device and especially for a rotational device such as a knob, which allows easier selection of menu items, menus, values or other options by the user.
Abstract: The present invention provides haptic sensations for a haptic feedback device and especially for a rotational device such as a knob. Force effects such as a hill force effect and barrier force effect allow easier selection of menu items, menus, values, or other options by the user. Force models are also described to allow greater selection functionality, such as a scrolling list with detents and rate control borders, a jog shuttle, a push-turn model, a double-push model, and a cast control model.

TL;DR: Results show that haptic force feedback significantly improvestask performance, perceived task performance, and pereceived virtual presence in the collaborative distributed environment, and suggests that haaptic force feedback increases perceived social presence.
Abstract: An experimental study of interaction in a collaborative desktop virtual environment is described. The aim of the experiment was to investigate if added haptic force feedback in such an environment affects perceived virtual presence, perceived social presence, perceived task performance, and task performance. A between-group design was employed, where seven pairs of subjects used an interface with graphic representation of the environment, audio connection, and haptic force feedback. Seven other pairs of subjects used an interface without haptic force feedback, but with identical features otherwise. The PHANToM, a one-point haptic device, was used for the haptic force feedback, and a program especially developed for the purpose provided the virtual environment. The program enables for two individuals placed in different locations to simultaneously feel and manipulate dynamic objects in a shared desktop virtual environment. Results show that haptic force feedback significantly improves task performance, perceived task performance, and pereceived virtual presence in the collaborative distributed environment. The results suggest that haptic force feedback increases perceived social presence, but the difference is not significant.
