Physical interactive environments can come in many forms: museum installations, amusement parks, experimental theaters, and more. Programming these environments has historically been done by adults, and children, as the visiting participants, have been offered few pre-created choices to explore. Given these creative limitations, the goal of our research has been to develop programming tools for physical interactive environments that are appropriate for use by young children (ages 4-6). We have explored numerous design approaches over the past two years. Recently we began focusing on a "physical programming" approach and developed a wizard-of-oz prototype for young children. This paper presents the motivation for this research, the evolution of our programming approach, and our recent explorations with children.
For applications such as video surveillance and humancomputer interface, we propose an efficiently integrated method to detect and track faces. Various visual cues are combined to the algorithm: motion, skin color, g...

The tutorial begins with a model of creative processes and refines it into design principles. Participants will learn of eight ways to improve software that supports human creative processes: searching and browsing digital libraries, visualizing data and processes, consulting with peers and mentors, thinking by free associations, exploring solutions: what-if tools, composing artifacts and performances, reviewing and replaying session histories, and disseminating results. These practical suggestions can be integrated into existing software applications, built into web services, or serve as the framework for novel tools. Software examples will be shown and brainstorming sessions will use projects from participants.

As more information resources become accessible using computers, our digital interfaces to those resources need to be appropriate for all people. However, digital library interfaces have typically been designed for older children or adults. In this demonstration, we present SearchKids, a digital library interface developmentally appropriate for young children (age 5-10 years old). SearchKids offers a graphical interface for querying, browsing and reviewing search results.

An emotion recognition system based on processing of multiple physiological signals is presented. Our algorithm is developed and verified based on multiple subjects by presenting multimodal stimuli that were elaborated to effectively induce emotions, and thus not dependent on single specific user. The system utilizes physiological signals that can be acquired without discomfort from body surface. Support vector machine was introduced as pattern classifier to overcome the difficulty of large overlap among clusters and large variance within cluster. Correct classification ratio was 77.8 and 61.2%, for emotion recognition problem of three and four categories, respectively. Another advantage of our system is that it requires shorter signal monitoring time than previous ones, and thus better suited for practical use.

The rapid growth of Short Message Service (SMS) text messaging is generating substantial commercial and research interest in fast and efficient text input methods for mobile devices. This paper presents an empirical study that compares three mobile phone text input techniques. The methods are 'multi-press input with timeout', 'multi-press input with a next button', and 'two-key'. The study shows that there is a significant speed difference, in words per minute (wpm), between the methods. The multi-press with next method provided the most rapid text input at 7.2 wpm, followed by multi-press with timeout at 6.4 wpm. The two-key method was the slowest at 5.5 wpm. These results are much slower than those predicted by Fitts' Law models reported in prior research. Subjective results regarding learnability, errors and efficiency showed no significant difference between the methods.

This research aims to investigate a collection of interactions in 2D workspaces with the goal of helping users stay in the flow of their activity. These interactions will be explored in the context of two software tools designed to support information work. The first tool, Niagara, addresses the early phases of this work that involve organization and synthesis. CounterPoint, the second tool, targets the later stages of this work that concern the authoring, delivery, and understanding of presentations.

This paper introduces a technique for viewing text objects under changing size constraints in 2D environments. Our approach automatically combines font size reduction and content reduction to preserve legibility of key words. Unlike traditional semantic zooming, our approach creates intermediate representations and transitions automatically. The main benefit is that it provides more meaningful views for different object sizes without additional authoring effort.

Collaborative storytelling occurs frequently when children play, but few efforts have been made to support it with computers. This demonstration presents KidPad, a collaborative storytelling tool that supports children creating hyperlinked stories in a large two-dimensional zoomable space. Through the use of local tools, KidPad provides children with advanced interaction techniques in a collaborative environment.

In this paper we describe an evaluation of behavioral descriptors generated from an analysis of a large collection of Usenet newsgroup messages. The metrics describe aspects of newsgroup authors' behavior over time;such information can aid in filtering, sorting, and recommending content from public discussion spaces like newsgroups. To assess the value of a variety of these behavioral descriptors, we compared 22 participants' subjective evaluations of authors whose messages they read to behavioral metrics describing the same authors. We found that many metrics, particularly the longevity and frequency of participation, the number of newsgroups to which authors contribute messages, and the amount they contribute to each thread, correlate highly with readers' subjective evaluations of the authors.
