Method of providing vibro-tactile feedback to a user of a user interface device comprising at least one actuator adapted to provide vibro-tactile feedback to the user and communicatively coupled to an application device, a vibro-tactile feedback providing device and vibro-tactile feedback providing system as well as a computer program product for carry out said method.

Vibro-tactile feedback method and device

A force-feedback device comprising a first member; a first kinematics bond being coupled with said first member; said first kinematics bond being constructed to provide at least one degree of freedom for movements of said first member; said first kinematics bond comprising a braking device being constructed to constrain movements of the said first member in at least one of said at least one degree of freedom; and a energy storing/release device being constructed to store energy in response to a movement of said first member in at least one of said at least one degree of freedom constrained by said braking device. A method of providing force-feedback including constraining a movement of a member of a haptic device in at least one degree of freedom; moving the member, by an externally applied force, in at least one of the at least one constraint degree of freedom; storing energy generated by the moving of the member; determining a force required to move the member in at least one of the at least one constraint degree of freedom; releasing at least a portion of the stored energy to generate at least a portion of the required force and transmitting the at least a portion of the required force to the member.

Force-feedback device and method

A device for transmitting movements comprising a parallel kinematics transmission structure adapted to provide at least one degree of freedom including three translational degrees of freedom, the parallel kinematics transmission structure further comprising a base member (), a moveable member (), and at least one parallel kinematics chain () coupling the base member () and the moveable member (), each parallel kinematics chain () having a first arm () moveable in a movement plane wherein the movement planes are at a distance to a symmetry axis (), and each parallel kinematics chain () comprising a second arm () coupled to the moveable member (), wherein a first end () of the second arm () is adapted to be coupled to the first arm () and a second end () of the second arm () is adapted to be coupled to the moveable member ().

Device for transmitting movements and components thereof

An active gripper for a haptic device including a parallel kinematics structure providing at least three degrees of freedom including three translational degrees of freedom, wherein the gripper comprises a first contact surface being adapted for contact by a first portion of a hand of a user, a second contact surface being adapted for contact by a second portion of the user's hand, which hand's second portion being moveable in relation to the hand's first portion, and a moveable member arranged between the first contact surface and the second contact surface and being adapted to actively move the first contact surface and the second contact surface in relation to each other.

Active gripper for haptic devices

A workspace expansion controller for human interface systems is provided. The controller resolves the physical workspace constraint by relocating the physical workspace of the device mapped inside the environment (virtual or robot) towards the area of interest of the operator without disturbing his or her perception of the environment. The controller is based on the fact that people are greatly influenced by what they perceive visually and often do not notice small deviations in their hand unless that small deviation has a corresponding visual component. With this new control approach the operator can explore much larger workspaces without losing spatial resolution through high scaling factors and thus avoid the drawbacks of indexing common with current approaches.
