EMPop: Pin Based Electromagnetic Actuation for Projection Mapping by Sungbaek Kim(Ph.D Student), Doyo Choi(MS Student) and professor Jinjoon Lee was accepted at CHI EA '24 Interactivity.
Abstract : As interactive media arts evolve, there is a growing demand for technologies that offer multisensory experiences beyond audiovisual elements in large-scale projection mapping exhibitions. However, traditional methods of providing tactile feedback are impractical in expansive settings due to their bulk and complexity. The EMPop system is the proposed solution, utilizing a straightforward design of electromagnets and permanent magnets making projection mapping more interactive and engaging. Our system is designed to control three permanent magnets individually with one electromagnet by adjusting the current of the electromagnet, reliable and scalable. We assessed its ability to convey directions and the strength of feedback, finding that users correctly identified directions and differentiated feedback intensity levels. Participants enjoyed the realistic and engaging experience, suggesting EMPop’s potential for enriching interactive installations in museums and galleries.
