- Marker technology is an enduring research theme in augmented reality (AR). Despite the extensive use of conventional paper-printed markers, many alternatives using LEDs, thermochromic ink [Peiris et al. 2011], and digital monitors and screens have been presented as dynamic content increases in AR applications. However such markers require a physical installation on the object and the digital displays limit the marker movement. Recent projector technology has demonstrated the potential of pico projectors as secondary displays in interactive mobile applications. In particular, the infinite focus ability of laser-based projectors allows the image to span surfaces at different depths; therefore manual focusing is avoided. In this context, we propose the use of pico projector coupled with a smart phone to create optical markers on planar surfaces. Our approach enables users to avoid cumbersomeness making physical markers and to design and share AR scenes intuitively and fast. Our vision of the future application of projected markers assumes a continuation of technological advance in projection and computer vision. Given projected markers and hand gesture interface to manipulate the markers on the projection surface, we can create and edit AR scenes so easily, and it facilitates iterative design process of AR applications. Moreover we can share the work with collaborators. In the current prototype, we provide an interface for users to select markers and edit the layout interactively on the smart phone display.
