Camping in the Gigital Wilderness:


Tents and Flashlights as Interfaces to Virtual Worlds

"ABSTRACT: A projection screen in the shape of a tent provides children with a shared immersive experience of a virtual world based on the metaphor of camping. RFID aerials at its entrances sense tagged children and objects as they enter and leave. Video tracking allows multiple flashlights to be used as pointing devices. The tent is an example of a traversable interface, designed for deployment in public spaces such as museums, galleries and classrooms.

Keywords: Virtual environments, immersive and traversable interfaces, RFID, video tracking, single display groupware.

INTRODUCTION: Pitching a tent and spending the night under canvass, with friends, a rucksack, a flashlight, surrounded by strange shadows and sounds, is an exciting experience for most children. It is also often the closest that many come to the wilderness, a primitive unfamiliar place that is far removed from their everyday world...

THE TENT AS HCI: As an interface, the tent reflects several current concerns within HCI. First, it represents an example of a traversable interface that provides the illusion of crossing into and out of a virtual world. Previous examples have included fabric curtains, sliding doors, hinged screens and even water sprays [3]. The tent demonstrates an alternative in which participants enter a space that is defined by the screen, but where unlike CAVE-style immersive interfaces, the space outside the screen is also part of the experience."
