Generating Emotion Models for Loomo​

To model emotions on a robotic system like Loomo, we need to formalise emotional expressions first. This project is a first approach to model emotions based on human basic emotions.

Next to emotional expressions based on human emotions, expressions based on animal behaviour could be interesting as well as they are potentially transferrable onto non-humanoid robots.

Defining an emotion model that can be applied to Loomo to express emotions. Master project by Maximilian Feigl

Abstract

In times of need for care personal their robotic counterparts are an interesting and striving research topic. To improve the coexistence of robots and humans it is important for robots to be able to display emotions. Because the current development process of specific models for each robot is very expensive, the objective of this thesis is to develop a universally usable model which can automatically display emotions for robots with different capabilities and limitations. Therefore the first step is to sight the literature about emotions to map specific movements and facial expressions to specific emotions. Afterwards the specific needs, to enable as many robots as possible to display emotions, for such a model are reviewed. This review shows that feature models already have the capability to display most of the needed notation, which leads to them beeing used as the basis of the here introduced emotion models. To check wether said models have the ability to create recognizable emotions an android library is created which is used to enable the robot Loomo of Segway Robotics display emotions. The performed user study shows that basic emotions are easily distinguishable and have 80 % recognition rate, while other emotions lacked behind because of the missing context that is needed to identify them.

Abstract

[…] Animals might present an alternative approach. Lacking resemblance to humans, animals, especially pets, still manage to express emotions which can be received and partly understood. In [Lak+14] Latakos et al. attempted to mimic a dogs behavior with a robot. The Paro is a robot with the appearance and (superficial) behavior of a baby seal[Sab+13]. It is supposed to provide company for the elderly by reacting to verbal or physical actions. This suggests that human-animal-interaction might help to improve human-robot-interaction.

Delbaere et al. explained how objects are personified in ads to be perceived as humanoid or anthropomorphic [DMP11]. They observed that emotional reactions are caused and lead to an increased acceptance of the advertised product.

There are various instances of pop culture where an emotional bond to a figure is created despite the lack of any human resemblance. The nature of the figure can range from animals to inanimate objects (Fig 1.2) to robots (Fig 1.1). That suggests there are mechanisms that enable humans to have emotional relationships to non-human beings. […]
