In a world of increasing customisations, Tanaka have released an automatic door that goes beyond the standard door that opens when you set off a particular sensor. This door calculates the shape of the person or object approaching and using clever horizontal sliders, opens to the optimal shape to allow entry.
Cool this door is, but it also helps in keeping the ‘cool weather’ out, minimising dust, pollen and bugs while keeping the temporature constant on the inside.
Here is a link to a video of the door in operation, whilst it is in Japanese the video does make for interesting viewing.
The applications? Besides high tech manufacturing or Tokyo high class outlets, I imagine the door could make for an interesting entry to a Jazz bar (assuming you could have some of the panels black to look like a piano).
