Development and Evaluation of LuminantCube: Omnidirectional and Auto-stereoscopic 3D Display

[ヒューマンインタフェースシンポジウム2016] 日時 : 2016年9月6日 - 9日, 会場 : 東京農工大学 小金井キャンパスIn this research, a new 3D display named “LuminatCube” which provides omnidirectional andauto-stereoscopic views was developed. This display is composed of a glass cube and laser projectors.LuminantCube was realized by diffusion of lights projected from the projectors, caused within a volumetricallyarranged micro voids processed numerously and randomly inside the cube. Calibration algorithm andmiddleware were developed. The calibration algorithm makes correspondence table between pixels of theprojector and luminous voids. The middleware converts STL files to data for LuminantCube. Subjectiveexperiments were conducted to evaluate the display performance. Results show that the 3D solid shape such assphere and cuboid can be recognized by 65 % of subjects at the size of 35 [mm] in width. Results also show thatthe depth can be perceived by binocular parallax with an accuracy of 2 [mm] by 85 [%] of subjects
