Haptic stimulus associated with other sensory content is generated for conveyance to one or more users with the other sensory content. This may enhance the experience provided to the one or more users by the content. The sensory content may include video content, video game content, audio content, and/or other content. The haptic stimulus may be varied based on position information. Such position information may include information related to the position of the one or more users, the position of a controller (e.g., a game controller), the position of an actuator delivering the haptic stimulus, and/or other position information.

System and method for providing haptic stimulus based on position

A master device for surgical robots may comprise: handle units, each of which includes at least one multi-joint robot finger configured to control a robotic surgical instrument on a robot arm of a slave device; and/or a micro motion generation unit configured to generate a control signal to control an end of the at least one multi-joint robot finger so as to move along a virtual trajectory. A master device for surgical robots may comprise: a first unit that comprises at least one multi-joint robot finger on a robot arm of a slave device; and/or a second unit configured to generate a first control signal to control the at least one multi-joint robot finger so as to move along a virtual trajectory.

Master devices for surgical robots and control methods thereof

PROBLEM TO BE SOLVED: To provide remote manipulation techniques for precisely transmitting (presenting), to an operator operating a main manipulating device, the orientation of reaction force exerted on a sub-manipulating device by a remotely manipulated object.SOLUTION: A fingertip stimulation system S comprises: a plurality of nozzles 9 which jet air to respective different positions on a pad of a prescribed finger of an operator operating a force sense presenting device 5; servo valves 8 which adjust the amounts of air jetted respectively out of the plurality of nozzles 9; and a control part 43 which determines the amounts of air jetted respectively out of the plurality of nozzles 9 on the basis of the orientation of reaction force exerted by a remotely manipulated object on a manipulator 1 motion-controlled remotely in accordance with the operation of the force sense presenting device 5, and sends the servo valves 8 a control signal regarding the determined amounts of air.

The invention discloses a colored touch and visual system, a touch display writer, a touch display writing unit and a touch display writing method The touch display writing unit comprises a probe with a contact tip, at least one first actuator, at least one second actuator and a third actuator, wherein the first actuator and the second actuator are coupled with the probe, so that the tip of the probe moves in one or more first directions and in the first traverse direction through the starting of the actuators; the traverse direction has a first vector which is different from that of the first directions in an x-y plane; and the third actuator is coupled with the probe

Colored touch and visual system, touch display writer, and touch display writing unit and method

A tactile display writer unit includes a probe having a contact tip, and at least a first actuator and a second actuator coupled to the probe, whereby activation of the actuators results in a displacement of the probe tip in one or more of a z-direction and in a lateral direction having a vector in an x-y plane. Also, a display writer includes a plurality of such units supported in an x-y array. The writer units may have a third actuator coupled to the probe. Also, a tactile vision system includes such a display writer, an image processor, and an image sensor. The processor transforms RGB image information from the image sensor into hue-based information having two or more attributes; and the actuators in the tactile display writer are activated by the information attributes. Also, a method for producing a tactile color stimulus at a site on the skin of a subject includes providing a probe having a contact tip; displacing the tip at the contact site in a direction generally normal to the skin surface at the site to an extent that relates one attribute of a hue-based model of the color, and displacing the tip in at least one lateral direction generally in a plane parallel to the skin surface at the site to an extent that relates to at least one additional attribute of the color.

Color tactile vision system

A tactile display having tactile pins (33) and presenting a tactile sense corresponding to the texture of the surface of an object and the sense of torque of the object. A tactile display (1) comprises a tactile sense presenting member (31) and tactile pins (33). The tactile sense presenting member (31) has a predetermined first surface on which a finger of a hand (7) of a human being is placed and holes in the first surface. The tactile pins (33) project from the holes and are movable at least parallel to the first surface. The ends of the tactile pins (33) are touched by the finger of the hand (7) of the human being, and the tactile sense corresponding to the texture of the surface of the object and the sense of torque of the object are presented to the finger of the human being.
