In this study, we apply gray-code to a remote direct pointing system. Gray-code is a method for automatic projection calibration. Gray-code binary patterns are projected to discover the locations of objects within the projector's perspective. In addition to this main feature, gray-code is capable of identifying a location within the projector's perspective from wherever the gray-code binary patters can be seen. We take this advantage of gray-code to build a remote direct pointing system. We build a prototype of the system that helps remote users draw directly onto remote objects. In the prototype, users see remote objects through cameras and draw on the objects simply by positioning the pointer on the images from the cameras. This property helps remote users get involved in remote environments. We describe the design of the prototype and also show an example of the prototype in use. The remote pen enables remote users to draw directly onto a remote desk or note.
