Finger beam for generating haptic feedback

A wearable haptic device for generating haptic feedback according to movement of an appendage of a user, the wearable haptic device comprising:

• an enclosure that defines an internal cavity having a size and shape to receive the appendage;
• a controller that is configured to generate a feedback parameter based on the movement of the appendage;
• an electrode that is configured to generate an electrical signal based on the feedback parameter;
• and
• a haptic feedback component carried within the internal cavity, wherein the haptic feedback component has a first portion, a second portion that extends from the first portion, and a haptic element on a first surface of the second portion, wherein haptic element is configured to actuate and move the second portion relative to the first portion from an initial configuration to a modified configuration upon receiving the electrical signal, wherein the haptic feedback component is configured to apply a force against the appendage of the user with a second surface of the second portion that is opposite the first surface, thereby generating the haptic feedback towards the appendage so as to be perceived by the user.

A method for generating haptic feedback using a haptic feedback device according to movement of an appendage of a user, the method comprising:

• with a controller, receiving a motion parameter from an accelerometer;
• with the controller, generating a feedback parameter based on the motion parameter;
• and
• actuating a haptic feedback element on a first surface of a first portion of a haptic feedback component to move the first portion relative to a second portion of the haptic feedback component from an initial configuration to a modified configuration so as to apply a force against the appendage of the user with an opposing second surface of the first portion, thereby generating the haptic feedback based on the motion parameter and the feedback parameter.
