AboutAbout the lab
Creating new video and display technologies that merge the real and the virtual
Hashimoto Lab studies video and display technologies that create new visual experiences, focusing on immersive virtual environments, wide field-of-view HMDs, and autostereoscopic 3D image presentation.
By actively exploiting the characteristics of human vision, the lab aims to achieve image presentation that goes beyond the limits of conventional hardware.
The lab's research is presented under three themes: technologies for entering the visual world, technologies for wearing the visual world, and technologies for touching the visual world.
Lab visits are accepted at any time.
Visitors who wish to see demos are advised to use the lab open houses held during Open Campus and Open Lab events.

ResearchResearch themes
Hashimoto Lab works on new video and display technologies that merge the real and the virtual. Under three themes (entering, wearing, and touching the visual world), the lab aims to create new visual experiences.
*Illustrative imageTechnologies for entering the visual world
The lab studies ways to blend life-size virtual worlds into ordinary rooms and familiar spaces, rather than dedicated facilities. Images from multiple projectors are corrected and stitched together across walls and floors, turning the whole space into a single visual world.
*Illustrative imageTechnologies for wearing the visual world
The lab studies ways to achieve a wide field of view, wider than an HMD alone can cover, with a lightweight setup. Its work includes projection onto a screen worn on the head and a simple HMD built from a multi-view display and mirrors.
*Illustrative imageTechnologies for touching the visual world
The lab studies dynamic projection mapping, which re-projects images to follow the motion of an object held in the hand; mid-air 3D images that can be seen without special glasses; and depth extension, which keeps images sharp from the near end to the far end.
