Electronic Treasure Hunt : Real-time Cooperation Type Entertainment System that Uses Location Information

MUNEMORI JUN, MIYAI SHUNSUKE, ITOU JUNKO

IPSJ SIG Notes  2006.05.31   Information Processing Society of Japan (IPSJ)

　View Summary

The electronic treasure hunt developed this time uses location information and operates avatar. The participant competes for the point looking for the treasure arranged virtually. The features of this game are that a treasure cannot be obtained if two people do not cooperate and a pictograph communication. From concentrated experiments of pleasurability, the following points became clear that participants evaluated highly the avatar operation system that used GPS location information. Moreover, the cooperation system by which each player's position became a point allowed location information to be used well.

Information Sharing Place using Awareness Information

IPSJ SIG Notes  2006.03.23   Information Processing Society of Japan (IPSJ)

　View Summary

We have developed a communication support system named ISS including promoting function of communication among users who can communicate by sharing the hobby information, the personal information of situations, states and existence. We have applied the system to the work group such as a laboratory. The results of application show that the communication is enriched, becauseISS increases the chance of communication. Communication is inspired by a "non-genre message" or a manual judgment function.

Development and estimation of the chat system using sense of touch

YOSHIDA Hajime, YOSHINO Takashi, ITOU Junko, MUNEMORI Jun

IPSJ SIG Notes  2006.01.26   Information Processing Society of Japan (IPSJ)

　View Summary

We developed the input method that uses sense of touch to input face marks. Using this method, You can input face marks if you grip the mouse. The feature of this system is that you can input two or more kinds of face marks according to how to grip a mouse. We applied this input method to the seminar support system and presentation estimate system, and estimated this system. We found that the input method that changes the face marks according to the power to grip was good, and that not only the face marks but also texts were important.

A prototype of a chat system using message driven and interactive actions character

KNOWLEDGE-BASED INTELLIGENT INFORMATION AND ENGINEERING SYSTEMS, PT 3, PROCEEDINGS  2006   SPRINGER-VERLAG BERLIN

　View Summary

In this article, we present a chat system in which embodied characters behave as agents of users and automatically act on messages of the users and the other character's action. We display and exchange nonverbal expressions including gestures, eye-gazes, noddings, and facial expressions in daily conversation. Nonverbal expressions convey various kinds of information that is essential to make our face-to-face communication successful. In the previous work on social psychology, it is known that there are interdependences among nonverbal expressions between those from different persons in conversation with. each other. We apply this knowledge to the chat between embodied characters, so that 3D characters interactively act by user's messages. The system evaluation results demonstrated higher validity than the system that the user explicitly indicates the character's actions.

Development of Informational Share System for Smoothing Communications

Ozaki Hiroshi, Yoshino Takashi, Itou Junko, Munemori Jun

IPSJ SIG Notes  2006   Information Processing Society of Japan (IPSJ)

　View Summary

There are many communications tools through these network system, including chats bulletin boards, and video conferencing systems. If we have not enough information, we spend much time to communicate between our friends. We have developed an information sharing system, which will be enabled to communicate between friends smoothly. The system shared many data of the desktop windows and uses the stored data of chats. The stored data can be related to the present chat.

Forbidden city explorer: A guide system that gives priority to shared images and chats

Jun Munemori, Thai Minh Tri, Junko Itou

ENTERTAINMENT COMPUTING - ICEC 2006  2006   SPRINGER-VERLAG BERLIN

　View Summary

We have developed a prototype guide system, which was named The Forbidden City Explorer. This system has real-time information sharing functions including image data, chatting, and mutual location information. It gives priority to shared images and chats, supporting a friendly user interface and simple operation methods, especially creating shared images to be used by general people. We applied the system twice to the Forbidden City in Beijing. Users were Chinese. The results of the experiments are as follows: (1) The evaluation of the image data sharing function was timely. (2) With a simple operation, many shared images and chat messages were created.

Proposing the Interdependencies Model between Nonverbal Conversational Signals Displayed by Embodied Agents in a Dialogue

IEICE technical report  2005.11.24   The Institute of Electronics, Information and Communication Engineers

　View Summary

This paper proposes a method of properly controlling nonverbal conversation signals(NCS) displayed by embodied agents which inform users through their dialogues, according to the atmospheres. The controls is important not to convey misunderstanding meanings from their NCS to users. It reports in the field of social psychology that there are some interdependences between NCS expressed in person-to-person dialogue. We focus on the interdependences and classify each scenes of dialogue, aiming to inform audiences, into three essential situations. Then, we define the three situations as atmospheres, and propose a procedure to maintain the interdependences between NCS, which vary with the atmospheres. Finally, we experiment using NCS extracted by TV programs aiming to inform users through dialogues between TV personalities, and evaluate the NCS realized by our procedure.

A solution of lighting problems in Image-Based Rendering

Technical report of IEICE. PRMU  2001.03.16   The Institute of Electronics, Information and Communication Engineers

　View Summary

Usual Image-Based Rendering(IBR) has disadvantage in creating an image under an arbitrary illumination environment. Several peoples have discussed this illumination problem on the basis of picture sequences taken in many different illumination environments at a fixed point, based on the theory of the dichromatic model. They take heuristic approaches to deal with the specular reflection component, while some present a solution to the diffuse reflection component using the theory. In this paper, we present a procedure to create an image of dielectric objects from a virtual camera set in an arbitrary environment at an arbitrary position. The image is obtained from three image sequences taken in three kinds of illumination environments. The procedure includes a novel proposal of determining the points of specular refletion on the objects by calculating them using the theory of reflectance map.
