▎ 摘　　要

NOVELTY - The system has a analog to digital converting module converts the voltage signal of capacitance sensor into digital signal after the finger contact of pressure capacitance sensor. The CPU is provided with multimedia interactive program receives contact information collected by single chip computer. The analysis process determines the experience of the touched region to output the projection image signal to the imaging portion. A projection device outputs 3D projection image to wall preset position to realize interactive intelligent wall projection. USE - Graphene wall drawing based multimedia intelligent interactive projection system. ADVANTAGE - The imagination of designers and experienced peoples can be opened and the interactive wall 3D projection shows the static to dynamic display transition, from single to comprehensive experience based on the wall painting and 3 D projection. DESCRIPTION OF DRAWING(S) - The drawing shows the block diagram of the system. (Drawing includes non-English language text)
