The concept consists of a handheld and a frame. The mobile handheld tracks the remote user via GPS and offers a pre-programmed picture that is sent to the stationary handheld. The determination of image is done using machine learning techniques. If the image displayed is incorrect, the user can specify the correct image to be displayed. In addition to the picture, the remote device sends contextual information. This handheld operates as a model for the frame. The frame is connected to a server over the Internet that determines the appropriate image to display. The remote user can see the current image on the stationary device. The frame has a touch screen to enable the viewers to interact by sketching on the image. This user can write a short comment or annotate the picture and send it to the remote user. The sketch is displayed over the image upon which it was drawn but the remote user is not informed of the new sketch.
