Content of research

Improvement in the performance of stereoscopic displays and head-mounted displays (HMDs) has led to improvement in the quality of 3DCG and virtual reality (VR) experiences. With this research, we are studying the next generation of information interfaces. Aerial video display technology does not require displays, goggles, or other equipment in the space in front of the user. With the technology, 3DCG can be displayed in real space, and the user does not have to enter virtual space, thus it is possible to present information naturally, both in terms of equipment and visuals. Furthermore, the user can directly reach out to where the image is displayed, and can touch and move the image. In addition to realizing this aerial video display system in a desktop size, we are also researching the technology to create video content suitable for it.

Potential for social implementation

• ・Manufacture: design (3DCAD), assembly and evaluation
• ・Medical care: diagnosis, explanation and preoperative review
• ・Education: digital museum
• ・Entertainment: art appreciation and communication

Appealing points to industry and local governments

The aerial video display system is suitable for grasping, turning, viewing, and moving objects displayed as 3DCG. The experience of touching the aerial image itself is also appealing and can be applied in many fields. Technically, it is also important to cooperate with force-feedback technologies, and we are studying integration with them.
