MIT, How to Make Almost Anything

How simple can an instruction be?

One paradox of modern construction is that an architect will posess precise coordinates locating an element like a brick in digital space, but in order to communicate this information, we flatten our spatial data into series of 2D drawings for a builder to  reinterpret on site. Haptic Clash Detection explores a process where the digital space of the design model and the construction site are superimposed: geolocation ideas from the global positioning system (GPS) are substituted for traditional means of instructing the mason in order to skip drawings entirely.


A Site for Digital Instructions: The physical guides for Eladio Dieste’s Church of Atlántida showed the masons where to lay the bricks in space. Removing all of the physical structures, can we convey the same guidance with digital scaffolds?
