A sensor/camera-monitored, virtual image or holographic-type display device is provided and called a SENSOR-MONITORED, 3D, INTERACTIVE HOLOGRAPHIC FREESPACE CONTROL UNIT (HFCU). This invention allows user interactions with the virtual-images or holograms without contacting any physical surface; it is achieved via the use of a visually bounded freespace both with and without holographic-type assistance. The 3D Holographic-type Freespace Control Unit (HFCU) and the Gesture-Controlled 3D Interface Freespace (GCIF) are implemented to produce external and internal commands. The built hardware of the present invention include concave and convex mirror slices at the size, curvature(s), repetition, and locations so as to create the desired holograms/virtual images, optical real-object generation pieces (projectors, digital screens, other mediums as desired, etc.) placed to create the associated virtual images/holograms, sensor(s) for monitoring holographic-type spaces and reporting data, and the computer and software pieces/code used to analyze the collected data and execute further commands as directed
