In recent years, 3DCG characters have become widespread and are being used in-screen agents as avatarsfor interactive agents. In this study, we propose a method to give a sense of coexistence and unity of space by lettingthe user follow the background and the method of projecting the gaze target to the pupil. For the experiment, anagent that can manually select the gaze target was created and evaluated.

In a robot and human conversation, the robot’s flat voice is a one of the factor that boring conversation. Automatically adjust emotional expressions to speech from virtual emotion in a robot. In this study, I verify that communication will be smooth when it considers the flow of emotional change from the conversation history.

The miniaturization and decreasing cost of networking computers, alongwith the advancement of cloud infrastructure has eased the implementation of it inproducts for manufacturers. The increase in such products has led to the rise in IoTdevices with information-provision function. However, it is difficult to give suchfunction to products which engage in an one-way association in our daily life likedaily commodities, since it requires the device to have a wealth of computationalresource. In this paper, we propose Virtual IoT system, the approach which addinformation-giving functions to the non-computing objects using Mixed Realitytechnology. This system enables appropriate things to give adequate informationat the right timing. In this paper, we explain the detail and design of Virtual IoTsystem. In addition, we conduct an experiment to evaluate impression and usabilityof Virtual IoT to disclose the descriptive power.

Today’s telecommunication systems have been greatly evolving, while the video calls used on telepresence robots still seems bland. We hypothesize that the augmentation of video calls with Manga-Effects will help users attain a sense of familiarity and find entertaining components within their conversations. In specific, adding various Manga-Effects over the video call, respectively selected upon the users’ facial expression, will help visually emphasize certain emotions. This experiment analyzes the level of users’ involvement in the conversation, and verifies our hypothesis.

IoT devices which display life-support information to users is increasing. However, it is difficult to add information-giving function to the product which close to user’s life, i.e. commodity. In fact, this information is given from the device which have a wealth computation source. In this research, we propose the approach which add information-giving function to those IoT introduction difficult things, using augmented reality technology. This system enables right things to give right information in right timing.

Inadequate variety of personalities for communication robots may cause unnatural interac- tion with them and reduction in attachment. This paper proposes C2 AT2 HUB, where communication robots are characterized by changing tendency of affect transition based on long-term interaction with users. In C2AT2 HUB, robots’ affect is defined as two types; “interpersonal affect” and “emotions”, and transition of each type of affect is adjusted by history of users’ actions to robots in order to characterize robots gradually. Evaluation experiment revealed our approach characterizes robots naturally and improves impression of robots.
