One of the highlights of the ISRE conference was a key note address by Hiroshi Ishiguro from University of Osaka and the ATR. Prof. Ishiguro is well known for his work on creating machines that look like humans. Specifically, like particular humans - hence he refers to these as geminoids - as in twin. A different term is "actroid" - geminoid is in fact a registered trademark by ATR. Whether geminoid or actroid, they are all androids (or gynoids), i.e., machines that resemble male or female humans. The effect is stunning. Whether moving or not they are close enough to a "real" human being to have some sort of presence. Unless they are sitting in a corner and not doing much, they are not mistaken for being human (von der Pütten et al., 2011). However, they are also not "just" a machine. How much of humanity we perceive in these machines is one of the key research questions several research groups are currently investigating.
