Expressive face helps robot bridge 'uncanny valley'
A good-looking robot is seriously hard to find. Robots can be pretty, some even handsome, but as soon as they get too realistic they start to creep us out. A new system for helping robots to generate more realistic expressions might go some way to help.
Many years ago, roboticists realised that as you morph an abstract robot into a human you generate a peak of unease - the "uncanny valley principle" - that makes people feel uncomfortable when a robot looks realistic but not realistic enough. Some say it's because they remind us of a corpse. However, research has shown that if you manipulate the robotic images so that they are more attractive, you can bypass this feeling of unease.
To create a robot we are more likely to accept, life-like expressions are vital. That's why Nicole Lazzeri at the University of Pisa, Italy, and her colleagues have designed a "Hybrid Engine for Facial Expressions Synthesis" (HEFES) - a facial animation engine that gives realistic expressions to a humanoid robot called FACE.
FACE's appearance is modelled on one of the team's wives. "It's really realistic," says Lazzeri, who presented the work at BioRob in Rome last month. See for yourself in the video above.
To mimic the myriad expressions that facial muscles are capable of achieving, the team placed 32 motors around FACE's skull and upper torso that manipulate its polymer skin in the same way that real muscles do.
To create expressions they used a combination of motor movements based on the Facial Action Coding System (FACS) - a system created over 30 years ago which codes facial expressions in terms of anatomic muscle movements.
HEFES is used to control FACE's expressions. It is essentially a mathematical programme that creates an "emotional space" which a person can use to choose an expression for FACE that exists anywhere between one or more basic emotions, including anger, disgust, fear, happiness, sadness, and surprise. The algorithm then works out which motors need to be moved to create that expression or transition between two or more.
The team evaluated the accuracy of their expressions by asking five autistic and 15 non-autistic children to identify a set of expressions performed first by FACE and then by a psychologist. Both groups were able to identify happiness, anger and sadness but less able identify fear, disgust and surprise.
So is it more attractive? I'm not convinced. But FACE's ability to smoothly transition between one emotion and another is pretty remarkable. And not too creepy.

/ About us
Founded by Russian entrepreneur Dmitry Itskov in February 2011 with the participation of leading Russian specialists in the field of neural interfaces, robotics, artificial organs and systems.
The main goals of the 2045 Initiative: the creation and realization of a new strategy for the development of humanity which meets global civilization challenges; the creation of optimale conditions promoting the spiritual enlightenment of humanity; and the realization of a new futuristic reality based on 5 principles: high spirituality, high culture, high ethics, high science and high technologies.
The main science mega-project of the 2045 Initiative aims to create technologies enabling the transfer of a individual’s personality to a more advanced non-biological carrier, and extending life, including to the point of immortality. We devote particular attention to enabling the fullest possible dialogue between the world’s major spiritual traditions, science and society.
A large-scale transformation of humanity, comparable to some of the major spiritual and sci-tech revolutions in history, will require a new strategy. We believe this to be necessary to overcome existing crises, which threaten our planetary habitat and the continued existence of humanity as a species. With the 2045 Initiative, we hope to realize a new strategy for humanity's development, and in so doing, create a more productive, fulfilling, and satisfying future.
The "2045" team is working towards creating an international research center where leading scientists will be engaged in research and development in the fields of anthropomorphic robotics, living systems modeling and brain and consciousness modeling with the goal of transferring one’s individual consciousness to an artificial carrier and achieving cybernetic immortality.
An annual congress "The Global Future 2045" is organized by the Initiative to give platform for discussing mankind's evolutionary strategy based on technologies of cybernetic immortality as well as the possible impact of such technologies on global society, politics and economies of the future.
Future prospects of "2045" Initiative for society
2015-2020
The emergence and widespread use of affordable android "avatars" controlled by a "brain-computer" interface. Coupled with related technologies “avatars’ will give people a number of new features: ability to work in dangerous environments, perform rescue operations, travel in extreme situations etc.
Avatar components will be used in medicine for the rehabilitation of fully or partially disabled patients giving them prosthetic limbs or recover lost senses.
2020-2025
Creation of an autonomous life-support system for the human brain linked to a robot, ‘avatar’, will save people whose body is completely worn out or irreversibly damaged. Any patient with an intact brain will be able to return to a fully functioning bodily life. Such technologies will greatly enlarge the possibility of hybrid bio-electronic devices, thus creating a new IT revolution and will make all kinds of superimpositions of electronic and biological systems possible.
2030-2035
Creation of a computer model of the brain and human consciousness with the subsequent development of means to transfer individual consciousness onto an artificial carrier. This development will profoundly change the world, it will not only give everyone the possibility of cybernetic immortality but will also create a friendly artificial intelligence, expand human capabilities and provide opportunities for ordinary people to restore or modify their own brain multiple times. The final result at this stage can be a real revolution in the understanding of human nature that will completely change the human and technical prospects for humanity.
2045
This is the time when substance-independent minds will receive new bodies with capacities far exceeding those of ordinary humans. A new era for humanity will arrive! Changes will occur in all spheres of human activity – energy generation, transportation, politics, medicine, psychology, sciences, and so on.
Today it is hard to imagine a future when bodies consisting of nanorobots will become affordable and capable of taking any form. It is also hard to imagine body holograms featuring controlled matter. One thing is clear however: humanity, for the first time in its history, will make a fully managed evolutionary transition and eventually become a new species. Moreover, prerequisites for a large-scale expansion into outer space will be created as well.
