The disclosed system may include (1) a processor that generates an artificial environment that includes a virtual object, (2) a display that presents the artificial environment, (3) an input subsystem that detects tracks positioning of a body, and (4) a plurality of haptic actuators that are arranged to apply haptic feedback to a first plurality of locations on the body, where the processor (a) determines, based on the positioning of the body, a virtual contact of one of a second plurality of locations on the body with the virtual object, where the second plurality of locations is different from the first plurality of locations, and (b) activates, in response to the virtual contact, at least one of the plurality of haptic actuators based on a mapping of the second plurality of locations to the plurality of haptic actuators. Various other systems and methods are also disclosed.

Spatially offset haptic feedback

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.
