An apparatus for providing augmented reality (AR) includes a support frame supporting at least one transparent lens, at least one display module for displaying AR content through the at least one transparent lens, a sensing module for detecting image data from a forward direction of the support frame, and for sensing signals for changes in motion, shape, or a location of a user's hand or a location of a pointing tool, and a control module for detecting motion information of the user's hand or of the pointing tool based on the signals and the image data, for modulating the AR content to correspond to the motion information, and for providing the modulated AR content to the at least one display module.
