Faculty of Science and Technology, Tokyo University of Science


The Ohwada Research Lab is located in the Department of Industrial Administration, Faculty of Science and Technology, at the Tokyo University of Science. There, research and development is being carried out into technology that extracts and utilizes useful information from vast amounts of data. In particular, the lab members are working on the realization of a computer that is able to learn, and can extract and reuse knowledge to perform security monitoring, by summarizing and managing documents using artificial intelligence. By placing emphasis on discussion, the professors and students are working together to come up with various ideas to promote their research and development. Accordingly, they have a strong interest in creating an environment that facilitates the active exchange of opinions.

The 65-inch Interactive Plasma Display bridging the gap between speaker and listeners for freer and livelier discussions


  • A projector is suitable for giving lectures to many people, creating a presenter-to-audience relationship.
    →Promotes one-way communication from the speaker to the listeners, making the spontaneous exchange of opinions difficult.


Interactive Plasma Display benefits:
  • Screen size (65-inch) suitable for small group discussions
    →Creates an inclusive feeling between the speaker and listeners, thereby promoting a lively exchange of opinions
  • Multiple functions that will be used even more in the future
    →Being able to write directly on the screen makes discussions more efficient.
    →When connected to a web conferencing system, opinions can be exchanged directly with remote locations.

Customer's Challenges

In the Ohwada Research Lab, presentations were made using a projector. However, having the presenter standing by the screen created a presenter-audience situation, resulting in one-way communication that hampered the exchange of ideas.
This meant discussion often needed to be held after the presentation. While a projector may be suitable for a classroom of 20 to 30 people, they did not think it would help generate discussion in the lab.


The Interactive Plasma Display has yielded the following benefits:

● Since five to six people can comfortably have a discussion around the 65-inch display, the separation between the speaker and listeners has disappeared. This has enabled more effective discussions with a freer and livelier exchange of opinions.

● By displaying prepared materials on the large screen, the entire group can easily see and discuss the materials.

● The display has many functions that will provide even more convenience in the future.
—Although not used much in the lab, presenters can write directly on the displayed materials when necessary.
—The display can be even more effectively used once a web conferencing system has been set up.

● The display is rugged and impact resistant.

Sitting around the display fosters group cohesiveness, and leads to brisk sharing of opinions

Decisive Factors for Interactive Plasma Display Installation

Professor Ohwada saw the Panasonic Interactive Plasma Display in his university co-op catalogue. He realized that it could help promote more natural and dynamic discussions in the lab, which led to the recent installation of the display. Once the new academic year begins, Professor Ohwada expects the display to be fully utilized. As of July 2013, it is already being used for presentations, discussions, and small classes.

Actual Use Cases

For group discussions

The purchased display has been connected to the shared lab computer. Students are now able to deliver PowerPoint and other presentations of their research results for group discussion. Since all the participants sitting around the 65-inch display can focus on the materials while discussing them, it promotes more dynamic and efficient exchange of opinions. When the materials need to be modified during the course of the discussion, the changes are made using the lab computer and are immediately shown on the display. This helps maintain the discussion flow. In addition to these student discussions in the Ohwada Research Lab, the display is used to check materials before presenting them at a conference.

For small classes

The Interactive Plasma Display is used to show source code during programming classes of five to six students. With a picture that is sharper than a projector image, it is especially good for displaying a lot of text. The electronic pen can be used to write directly on the screen, for clearer classroom explanations.

Participants exchanging opinions while looking at the same presentation materials. When a material needs to be revised, the change is made on the presentation computer and immediately appears on the display. This helps maintain discussion flow.

With the table and chairs compactly arranged in front of the 65-inch display, the environment is conducive to discussion.

Due to its wide viewing angle, even those standing or sitting to the side of the Interactive Plasma Display can enjoy the same display color and brightness quality. This makes it possible for everyone to participate in discussions viewing the same clear images.

Whiteboard software offers even greater convenience

The display's whiteboard software can be utilized from a USB flash drive without the need for prior installation on the computer. After learning about this feature, Assistant Professor Kanamori was quite impressed and indicated that it is very convenient for students when they connect their laptop computers to make presentations.
