Takaharu Suzuki and Tetsuro Sonoda from Ikeda-Lab and Keio University have used Fologram in their project ‘Smart Giant Block’. The project uses Aruco markers attached to a large repetitive component to give users wearing a HoloLens real time feedback in the assembly of a collection of repeating block elements. The Aruco markers are tracked in real time with Fologram to give feedback on the location and position of the physical object in the digital model.
