“…The HEICEM’s structure highlights multiple levels of investigation and analysis, which require different disciplines—from humanities and Sexology, to neurosciences, AI and HMI, and cognitive, social, and cultural sciences—to weigh in, if we want to fully grasp the factors and variations of our co-evolution with erobots. Noteworthy, at the moment, some of these phenomena are difficult to examine empirically without solely relying on self-report and hypothetical scenarios [ 87 , 219 , 265 ], partly due to the unavailability, high price, and/or novelty of (sophisticated) erobotic systems. Others, however, can already be observed (and studied)—to various degrees—through individuals, communities, and cultures related to: digi/techno sexuality [ 21 , 200 , 283 ], cybersex (or online sexuality; [ 67 , 85 ]), hentai (i.e., manga or anime pornography; [ 301 ]) and otakuism (i.e., interests in animation, manga, and games, often incorporating (non-)fictional technology; [ 11 , 304 ]), dolls [ 87 , 104 , 166 , 174 , 280 , 294 ], toys [ 86 , 89 , 90 , 138 , 247 , 253 ], platforms [ 49 ], games [ 80 ], teledildonics [ 85 , 107 , 200 ], (VR/AR/MR) pornography [ 254 , 275 ], (AI-powered) dating applications [ 197 , 208 , 281 ], artificial partners [ 87 , 112 , 160 , 200 , 219 , 237 , 307 ], as well as objectophilia, agalmatophilia/pygmalionism, and mechanophilia (i.e., respectively, the (sexual and/or romantic) attraction to objects, statue/dolls/mannequins, and machines; [ 102 , 317 ].…”
