Handheld ProjectorHandheld projectors or pocket projectors or are an emerging technology that applies the use of a projector to the handheld computer paradigm, theoretically allowing for interesting new ways to communicate. Among the fundamental problems with ever-shrinking cell phones, PDAs, digital cameras, and other portable devices is that they carry more and more of our data, but they are decreasing in size such as to make them inconvenient to use in certain respects. Building tiny projectors into these devices, may offer a practical solution. Research teams have developed miniature hardware and software that can project digital images onto whatever surface is handythe wall, say, or a desktopand make them look good even if the impromptu screen isnt nice and smooth. =External links *New York Times article about pocket projectors
