Alternatively, a tripod could be used for displaying the projected image on a surface. Since the projector lens would be mounted on the side of the iPhone or iPad, an image could be projected on a wall simply by placing the device on a flat surface. Shadow or silhouette gestures would be detected with a camera, then analyzed with image-processing software. Figures in the patent show a swipe-type motion, not unlike what's already used in iOS, would instigate the image transfer. ![]() For instance, an image could be shared from one projected display to another. The gesture-detecting technology would involve a library of gesture commands that could be used to easily share data. ![]() Intel researchers, for instance, have developed a projected display that behaves like a touchscreen. And although interactive displays, typically in the form of holograms, long have been a staple of science fiction, such technology has in recent years moved increasingly closer to a reality. ![]() Just last week we saw the development of a new glass lens tiny enough that it could eventually be used in mobile devices like smartphones and tablets.
