TL;DR: A haptic feedback planar touch control used to provide input to a computer is described in this article, where the computer can position a cursor in a displayed graphical environment based at least in part on the position signal, or perform a different function.
Abstract: A haptic feedback planar touch control used to provide input to a computer. A touch input device includes a planar touch surface that inputs a position signal to a processor of the computer based on a location of user contact on the touch surface. The computer can position a cursor in a displayed graphical environment based at least in part on the position signal, or perform a different function. At least one actuator is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user contacting the touch surface. The touch input device can be a touchpad separate from the computer's display screen, or can be a touch screen. Output haptic sensations on the touch input device can include pulses, vibrations, and spatial textures. The touch input device can include multiple different regions to control different computer functions.

TL;DR: In this article, a tactile feedback system is integrated onto a handle of a surgical tool that generates relevant feedback in at least the form of haptic effects to the user, i.e., the type of tissue or other structures located within the jaws of the stapler, whether the quantity or thickness of tissue inside the jaws is appropriate for the selected stapling cartridge, and whether the proper length of staples has been fired based on the length of tissue located in the jaws.
Abstract: A surgical tool system includes a surgical tool for cutting and stapling tissue and a tactile feedback system integrated onto a handle of the tool that generates relevant feedback in at least the form of haptic effects to the user. The tactile feedback alerts the user of tissue properties, i.e., the type of tissue or other structures located within the jaws of the stapler, whether the quantity or thickness of tissue located within the jaws of the stapler is appropriate for the selected stapler cartridge, whether the proper length of staples has been fired based on the length of tissue located in the jaws, whether a blood vessel is located within the jaws of the stapler, whether the stapling process has successfully sealed the tissue located within the jaws of the stapler, the position of the cutting element, and/or when the stapling procedure or firing cycle is completed.

TL;DR: A haptic feedback touch control used to provide input to a computer as discussed by the authors is a touch input device that includes a planar touch surface that provides position information to the computer based on the location of user contact.
Abstract: A haptic feedback touch control used to provide input to a computer. A touch input device includes a planar touch surface that provides position information to a computer based on a location of user contact. The computer can position a cursor in a displayed graphical environment based at least in part on the position information, or perform a different function. At least one actuator is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user. The actuator can move the touchpad laterally, or a separate surface member can be actuated. A flat E-core actuator, piezoelectric actuator, or other types of actuators can be used to provide forces. The touch input device can include multiple different regions to control different computer functions.

TL;DR: In this paper, a haptic device having a plurality of operational modes, including a first operational mode and a second operational mode, is provided, where each control scheme is uniquely associated with an operational mode from the plurality of operations.
Abstract: A haptic device having a plurality of operational modes, including a first operational mode and a second operational mode is provided. The first operational mode is associated with a frequency range. The second operational mode is associated with a frequency range that is different from the frequency range of the first operational mode. A controller is coupled to the haptic device, and is configured to send the haptic device a plurality of control schemes. Each control scheme is uniquely associated with an operational mode from the plurality of operational modes. Another embodiment provides a method that includes providing power to a haptic device configured to cause the haptic device to provide a haptic sensation above a pre-determined sensation threshold. A voltage pulse that is configured to change the haptic sensation output by the haptic device by a pre-determined amount within a pre-determined time period is also applied to the haptic device.

TL;DR: In this article, the authors proposed a host command protocol for controlling and providing force feedback using an interface device manipulated by a user and connected to a host computer system, where the host computer sends high level host commands to the local microprocessor and the microprocessor independently implements a local reflex process based on the high level command to provide force values to actuators using sensor data and other parameters.
Abstract: An apparatus (14) for controlling and providing force feedback using an interface device manipulated by a user and connected to a host computer system (12). A microprocessor (26) is provided local to the interface device and reads sensor data from sensors that describes the positioning of a user object moved by the user, such as a joystick. The microprocessor controls actuators (30) to provide forces on the user object. The host computer sends high level host commands to the local microprocessor and the microprocessor independently implements a local reflex process based on the high level command to provide force values to actuators using sensor data and other parameters. A host command protocol includes a variety of different types of host commands and associated command parameters. By providing a relatively small set of high level host commands, the protocol further shifts the computational burden from the host computer to the local microprocessor.
