Screen sharing with mapped holographic projections

A computer system comprising:

• a processor set;
• one or more computer readable storage media;
• and
• program instructions stored on the one or more computer readable storage media to cause the processor set to perform operations comprising:
• transmitting a screen image from a presenter computing device to a participant computing device;
• capturing, by a camera on the presenter computing device, a body movement image of a presenter;
• identifying a gesture in the body movement image, wherein the gesture includes a finger of the presenter that points to an area on the screen image;
• extracting vector information for the finger of the presenter that points to the area on the screen image;
• determining a location on the screen image based on the vector information;
• mapping the gesture to the screen image on the presenter computing device;
• generating a holographic projection of the mapped gesture of the presenter;
• and
• displaying, at the participant computing device, an overlay of the holographic projection on the screen image.
