“…In addition to the well-proven measurement technologies, it should become possible in future to semi-automatically capture the room geometry using the PTZ-camera and its laser distancemeasuring instrument. Finally, the camera tracks the position of a laser pointer to enable users to interact directly with the digital model [21].…”

At present, more than half of all building activity in the German building sector is undertaken within existing built contexts.The development of a conceptual and technological basis for the digital support of design directly on site, within an existing building context is the focus of the research project "Spatial Augmented Reality for Architecture" (SAR).This paper describes the goals achieved in one aspect of the project: the sampling of colors and materials at a scale of 1:1 using Augmented Reality (AR) technologies.We present initial results from the project; the development of an ad-hoc visualization of interactive data on arbitrary surfaces in real-world indoor environments using a mobile hardware setup.With this, it was possible to project the color and material qualities of a design directly onto almost all surfaces within a geometrically corrected, existing building. Initially, a software prototype "Spatial Augmented Reality for Architecture-Colored Architecture" (SAR-CA) was developed and then assessed based on evaluation results from a user study.

This poster presents Viewpoint Cursor, a technique for mapping 2D user input from devices such as mobile phones, trackballs, or computer mice, to 3D multi-projector spatial augmented reality systems. While the ubiquity of input devices such as these make them obvious choices for spatial augmented reality, their 2D nature makes them difficult to use. Existing VR techniques rely on a display in front of the user's eyes on which to place virtual information. Immersive spatial augmented reality systems allow users to experience and interact with projected virtual information from any angle, using arbitrary placement of projectors. Viewpoint Cursor addresses these issues by mapping 2D input to a plane in front of the user's view. Ray casting is then used to find the 3D location for the cursor in the scene, which is then projected using the projection system. The user's position is tracked, with the input remapped accordingly, resulting in 2D input that matches what the user expects, regardless of their location.

Abstract-The combined use of computers and projectors in delivering multimedia presentations and in teaching is very common. However, the common operating tools used to deliver presentations such as presentation pens or mice either have limited manipulation functionality or are less convenient, and it is difficult to perform functions such as zooming, rotating images, and writing. In addition to allowing users to move freely in space to remotely perform functions, the laser pen manipulation system proposed in this paper can also perform the writing functions of a laser pen. Moreover, the system can also support the simultaneous use of two laser pens to realize a touch mode similar to that of a tablet computer, thus achieving an intuitive projection display manipulation experience.Index Terms-Intuitive, laser pen, laser pointer, projection. I. INTRODUCTIONThe computer is a common piece of equipment in modern life, and the combined use of computers and projectors is widely applied in presentations and in teaching. However, the common computer presentation operating devices are mostly presentation pens and mice. Though people are very familiar with computer mice, they usually require the user to stay beside the computer and an operating table, thus resulting in restricted operation. In addition, writing is not smooth when using the mouse to perform writing functions. On the other hand, common and simple presentation pens have limited manipulation functions, such as laser guiding and page turning, and presentation pens with complex functions are often costly and unable to support the writing function. To this end, this paper proposed a set of intuitive projection display systems that are able to support the manipulation of two laser pens, thus enabling the most common laser pens to be used to perform a variety of manipulation and writing functions in an intuitive manner and deliver projected presentations efficiently.With its light condensing and non-scattering characteristics, in addition to common guiding and presentation features, the laser pen has other various applications. For example, it can be used as the aiming point in a shooting game [1], [2] or to direct a robot arm to grab real Manuscript received April 28, 2014; revised July 4, 2014 objects [3]. The laser pen can also be combined with augmented reality to derive more multivariate interactive applications [4], [5]. In the proposed system, the laser pen is used to manipulate the computer cursor to enable the user to remotely control a computer without needing to stay beside it, thus increasing the opportunity to interact with others during teaching or conference presentations, and further enhancing the effect of the presentation.Currently, many scholars are studying the use of laser pens or mobile devices to remotely control computers [6]- [10]. Pramit Dey et al. proposed a study on operating the window with a laser pen [6], however, was less intuitive compared the proposed system in this paper. Xiao-Jun Bi et al. designed a system called uPen [7] that c...
