▎ 摘　　要

NOVELTY - The device has a base (1) whose side is provided with a graphene wall (2). A middle portion of the graphene wall is provided with a movable door mechanism (3), where middle portion of the graphene wall is provided with hidden fan screen matrix units (4). A middle portion of the graphene wall is provided with hidden grooves, where side of the hidden grooves is rotatably connected with the movable door mechanism. An upper portion of the hidden grooves is provided with a linkage control groove. An upper portion of the movable door mechanism is set in the linkage control groove. USE - Augmented reality (AR) interaction device for a graphene wall surface. ADVANTAGE - The device uses a speaker to touch operation on the graphene wall for controlling multiple hidden fan screen matrix units, so that a pattern displayed by the matrix as foreground is controlled by the speaker touch operation to control the display content on the matrix, thus simulating effect of AR interaction and satisfying a multi-layer, and hence improving flexibility and realizing three-dimensional image display and interaction in an effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded view of an AR interaction device for graphene wall surface. 1Base 2Graphene wall 3Movable door mechanism 4Hidden fan screen matrix units
