Familiarity is one of the most important requirements for human symbiosis robots, such as care service robots. To improve familiarity of a human symbiosis robot, we proposed a novel concept called “robot avatar.” A robot avatar is a small robot mounted on a main robot, and it performs gestures instead of the main robot. Although our previous study revealed that a robot avatar was effective for increasing users’ familiarity with a robot, the effect of users’ age on the improvement of familiarity by a robot avatar was not investigated well because the most of the subjects in the previous study were young. When considering the application of a robot avatar to care service robots, it is important to investigate the effect of a robot avatar on elderly people. In this paper, we focus on elderly subjects, and carried out an experiment to test if a robot avatar is effective for elderly people to improve familiarity. The result was positive, and the effect of a robot avatar on elderly people was stronger than that on younger people. From a comparison of the results from elderly subjects with those from younger subjects, we found that the elderly paid less attention to dialogue between a human and a robot.

In this paper, we deal with melody completion, a technique which smoothly completes partially-masked melodies. Melody completion can be used to help people compose or arrange pieces of music in several ways, such as editing existing melodies or connecting two other melodies. In recent years, various methods have been proposed for realizing high-quality completion via neural networks. Therefore, in this research, we examine a method of melody completion based on an image completion network. We represent melodies as images and train a completion network to complete those images. The completion network consists of convolution layers and is trained in the framework of generative adversarial networks. We also consider chord progression from musical pieces as conditions. From the experimental result, it was confirmed that the network could generate original melody as a completion result and the quality of the generated melody was not significantly worse than the result of a simple example-based melody completion method.

This article briefly reviews the research works related to metacommunication. Metacommunication is a term meaning ``communication on communication,'' which is related to marginal communication such as conveying recognition, comprehension, and evaluation of an interlocutor's words. Herein, several research works are reviewed from the metacommunication point of view.
