Spectrum Hologram can be generated through digital glasses or contact lenses and a picture in picture can display another hologram or yourself if you needed to visualize yourself after being 3d scanned by a spectrum communications device.
The digital glasses and communications device is linked to spectrum communications and the accelerator satellite. Similar to a person seeing a rainbow after it rains there are half rainbows and full halo rainbows.
A small smart watch or light ring (hearing aid cpu) connected to Bluetooth allows voice control to send holographs to the digital glasses. The transporter sends orbital supply drops connected to a 3d replicator materializes the hologram.
