An apparatus for creating and tuning haptic feedback is provided. The apparatus includes (A) a brace with first and second portions, (B) a vibrotactile actuator, coupled to the first portion of the brace, configured to apply haptic stimulations to a user, and (C) a linear actuator, coupled to the second portion of the brace, configured to (i) obtain a signal generated based on information about the user's body at a target location of the user and (ii) adjust a tension of the brace according to the signal. In some embodiments, the apparatus also includes one or more sensors configured to generate the information about the user's body at the target location. Furthermore, a controller may be configured to: (i) generate the signal based on the information about the user's body at the target location generated by the one or more sensors and (ii) provide the signal to the linear actuator.

Impedance shaping for haptic interfaces on wearable devices

A method may include acquiring an audio signal, generating a haptic signal at frequencies that are based on a shift in frequencies of the audio signal, thereby causing the frequency of the haptic signal to match the frequency of the audio signal according to human perception and providing the haptic signal to a human user. Various other apparatuses, systems, and methods are also disclosed.

Systems, methods, and devices for audio-tactile mapping

Embodiments relate to a system and a method for providing haptic feedback to a user by controlling an area of a surface of a haptic assembly in touch (directly or indirectly) with a user. The haptic assembly can be actuated such that a surface area of the haptic assembly in contact with a user can be adjusted. An area of the haptic assembly in contact with a user can be changed by modifying a shape of the haptic assembly. Hence, by changing the shape of the haptic assembly, a user touching a virtual object in a virtual space with a particular rigidity can be emulated.

Haptic devices that simulate rigidity of virtual objects

A haptic device configured to provide haptic feedback to a user. In one aspect, a user or part of a user is located on the haptic device including actuators and damping elements. A haptic feedback wave is generated by an actuator and propagated to the user or part of the user on the haptic device. Damping elements receive the haptic feedback wave and suppress the haptic feedback wave to reduce a reflection thereof.

Haptic surface with damping apparatus

An actuator configured to provide haptic feedback to a user. The actuator is located on a plate and is configured to apply various excitations to the plate to generate a mechanical wave propagating in the controlled direction. The excitations can be a translational motion of the actuator (or a portion of the actuator) in two or three perpendicular axes. Alternatively, the excitations can be a non-translational motion (e.g., rotation about an axis) of the actuator (or a portion of the actuator). By generating the mechanical wave traveling in the controlled direction, loss of energy due to scattering of the mechanical wave can be obviated.
