Upponurkka is an inexpensive immersive display system for public virtual reality installations. It is designed for public places to be robust, wireless, and light-weight. The system consists of two passive stereo screens and optical tracking. In this paper the hardware and software of Upponurkka are briefly presented. In addition, experiences of using the system in a public art exhibition are reported.

We have studied the usability and artistic potential of an immersive 3D painting system in its early state. The system allows one to draw lines, meshes and particle clouds using a one-hand wand in a virtual room with stereoscopic display. In its more mature state the software will allow for two-handed interaction with new interaction devices. Ten professional artists participated for two days each in a test, performing both given tasks and free artistic sketching. Their experiences were collected through observation and interviews. At this stage, we found that common technical limitations of virtual environments, such as latency and tracking inaccuracy as well as clumsiness of the hardware devices, may considerably hinder handicraft work. On the other hand, every single participant felt that immersion offers new potential for artistic expression and was definitely willing to continue in the second phase of the test later this year.
