Massachusetts Institute of Technology (MIT) researchers have developed a technique to make augmented reality technologies more immersive by analyzing the physical behavior of an object and predicting how a structure will respond when different forces are applied.
The system categorizes visual data as vibrations operating at various frequencies, and software analyzes those vibrations to determine the types of forces creating those movements and predicts how different forces might affect the same object. For example, by recording a bush's reaction to the wind, the software can determine how it also might react to a stronger force.
In addition to fueling augmented reality games, MIT lead researcher Abe Davis says the method could be used to test a building's architectural integrity or simulate an explosion. Davis notes the architecture industry already uses vibration and frequency models, but companies rely on much more complicated and costly capture techniques to acquire and analyze the data.
"The big advantage [with my technique], is that it's very easy to point a camera at a building, but it's pretty hard to paint a whole building with accelerometers or laser points," Davis says. "This offers a convenient way to capture slightly lower quality data, which is great to figure out where you need to focus your attention."
