Vaucelle, C. "Play It by Eye, Frame It by Hand! Gesture Object Interfaces to Enable a World of Multiple Projections"

Abstract

Tangible Media as an area has not explored how the tangible handle is more than a marker or place-holder for digital data. Tangible Media can do more. It has the power to materialize and redefine our conception of space and content during the creative process. It can vary from an abstract token that represents a movie to an anthropomorphic plush that reflects the behavior of a sibling during play. My work begins by extending tangible concepts of representation and token-based interactions into movie editing and play scenarios. Through several design iterations and research studies, I establish tangible technologies to drive visual and oral perspectives along with finalized creative works, all during a child's play and exploration.

I define the framework, Gesture Object Interfaces, expanding on the fields of Tangible User Interaction and Gesture Recognition. Gesture is a mechanism that can reinforce or create the anthropomorphism of an object. It can give the object life. A Gesture Object is an object in hand while doing anthropomorphized gestures. Gesture Object Interfaces engender new visual and narrative perspectives as part of automatic film assembly during children's play. I generated a suite of automatic film assembly tools accessible to diverse users. The tools that I designed allow for capture, editing and performing to be completely indistinguishable from one another. Gestures integrated with objects become a coherent interface on top of natural play. I built a distributed, modular camera environment and gesture interaction to control that environment. The goal of these new technologies is to motivate children to take new visual and narrative perspectives.

In this dissertation I present four tangible platforms that I created as alternatives to the usual fragmented and sequential capturing, editing and performing of narratives available to users of current storytelling tools. I developed Play it by Eye, Frame it by hand, a new generation of narrative tools that shift the frame of reference from the eye to the hand, from the viewpoint (where the eye is) to the standpoint (where the hand is). In Play it by Eye, Frame it by Hand environments, children discover atypical perspectives through the lens of everyday objects. When using Picture This!, children imagine how an object would appear relative to the viewpoint of the toy. They iterate between trying and correcting in a world of multiple perspectives. The results are entirely new genres of child-created films, where children finally capture the cherished visual idioms of action and drama. I report my design process over the course of four tangible research projects that I evaluate during qualitative observations with over one hundred 4- to 14-year-old users. Based on these research findings, I propose a class of moviemaking tools that transform the way users interpret the world visually, and through storytelling.
