 Recent advancements in virtual reality, VR, technology have enabled the development of a perfect 3D virtual world, providing a cutting-edge social platform for humans. In addition to traditional visual, auditory and tactile senses, ALFACTION also plays a key role in influencing humans' physical and mental states. We propose a novel skin-interfaced ALFACTORY feedback system which utilizes wireless, programmable arrays of flexible and miniaturized ODA generators, OGs. The OGs are optimized for performance in terms of response rate, ODA concentration control, long-term operation, mechanical electrical stability and low power consumption. Demonstrations in 4D movies, smell messages, medical treatments, human emotion control and virtual reality augmented reality, VR AR, based online teaching showcase the potential of this new technology in various practical applications such as entertainment, education, human-machine interfaces and more.
