Was reading an article on bbc.co.uk which states that 3D TV could be with us pretty soon. How does that relate to e-learning you may ask. Well I know it seems pretty pie in the sky at the moment, but imagine the possibilities particularly for real-life training simulations. Imagine hospital staff being shown by 3D images how to lift a patient correctly or administer drugs to the correct area of the body. Or a machinist being shown how to clean down a machine safely. There are many applications where 2D just isnt rich enough and where face to face was really the only way forward.

At the meeting I went to at the Learning Light, the speaker demonstrated a handheld device that when pointed at a piece of paper on the table, it showed a screen with a 3d man walking across it and by walking around the piece of paper, you could see the man from all the different angles. It was very clever and I couldn't help thinking that one day soon, in much the same way as my kids marvel at stories of my first telly, my grandchildren will listen in awe as I tell them that I held one of the first devices that conveyed holographic images.
