First experiments with DIY holographic projection with digital puppetry.
Ravin Balakrishnan already in 2001 was exploring physical mockups to interact with 3D volumetric displays (User Interfaces for Volumetric Displays –
http://www.autodeskresearch.com/publications/volumetricui). Naiqi Weng made some interesting experiments with volumetric displays and digital puppetry in 2005. Andrew Jones extended this approach in 2007, (Rendering for an Interactive 360º Light Field Display- http://gl.ict.usc.edu/Research/3DDisplay/)
But this is a completely different approach, a low-cost solution that can be easily done with cheap materials and a standard computer display.
It is a four-sided hologram made with transparent plastic that sits above a computer screen. The screen is divided into four planes that reflects the performance animation manipulated by the digital puppeteer with his hands.
This experiment was made in PIC – Porto Interactive Center and the holographic structure was developed by Marcelo Gomes.
