Dolltalk: a computational toy to enhance children's creativity

This paper presents a novel approach and interface for encouraging children to tell and act out original stories. Dolltalk is a toy that simulates speech recognition by capturing the gestures and speech of a child. The toy then plays back a childs pretend-play speech in altered voices representing the characters of the childs story. Dolltalks tangible interface and ability to retell a childs story may enhance a childs creativity in narrative elaboration.

Hierarchical multi-class self similarities

The music similarity question is yet to be defined. From an objective signal point of view, at least three classes of similarities may be considered: pitch, rhythm, and timbre. Within each class, several scales of analysis may be evaluated: segment, beat, pattern, section. We propose a recursive approach to this hierarchical and perceptual similarity problem. Our musically meaningful set of measurements is computed from the ground up via dynamic programming. This may be regarded as an analysis foundation for content-based retrieval, song similarities, or manipulation systems.

Interacting with music in a social setting

This paper describes the design of a new system for interacting with music in a social setting. MusiCocktail allows users to influence certain parameters of a pre-composed and pre-recorded piece of music in the way they mix their beverages at a social gathering. This new form of interaction with music enables group participation in the creation of a rich musical environment.

Textable movie: improvising with a personal movie database

This sketch presents a new approach to improvising movies according to the inter-relationship between personal videos and the story of an experience. Textable Movie is a graphical interface that invites a storyteller of any age to compose and visualize movies, images and sound environments while writing a story; the system self-selects and self-edits movies in real time based on textual input from the teller. Textable Movie aims to exalt the imagination of its authors (writer, and film-maker) by immersing them in real time, in a co-constructed narration.
