In this paper, we present MonoTrans2, a new user interface to support monolingual translation;that is, translation by people who speak only the source or target language, but not both. Compared to previous systems, MonoTrans2 supports multiple edits in parallel, and shorter tasks with less translation context. In an experiment translating children's books, we show that MonoTrans2 is able to substantially close the gap between machine translation and human bilingual translations. The percentage of sentences rated 5 out of 5 for fluency and adequacy by both bilingual evaluators in our study increased from 10% for Google Translate output to 68% for MonoTrans2.

Social media is a place where users present themselves to the world, revealing personal details and insights into their lives. We are beginning to understand how some of this information can be utilized to improve the users' experiences with interfaces and with one another. In this paper, we are interested in the personality of users. Personality has been shown to be relevant to many types of interactions;it has been shown to be useful in predicting job satisfaction, professional and romantic relationship success, and even preference for different interfaces. Until now, to accurately gauge users' personalities, they needed to take a personality test. This made it impractical to use personality analysis in many social media domains. In this paper, we present a method by which a user's personality can be accurately predicted through the publicly available information on their Facebook profile. We will describe the type of data collected, our methods of analysis, and the results of predicting personality traits through machine learning. We then discuss the implications this has for social media design, interface design, and broader domains.

Event sequence analysis is an important task in many domains: medical researchers may study the patterns of transfers within the hospital for quality control;transportation experts may study accident response logs to identify best practices. In many cases they deal with thousands of records. While previous research has focused on searching and browsing, overview tasks are often overlooked. We introduce a novel interactive visual overview of event sequences called LifeFlow. LifeFlow is scalable, can summarize all possible sequences, and represents the temporal spacing of the events within sequences. Two case studies with healthcare and transportation domain experts are presented to illustrate the usefulness of LifeFlow. A user study with ten participants confirmed that after 15 minutes of training novice users were able to rapidly answer questions about the prevalence and temporal characteristics of sequences, find anomalies, and gain significant insight from the data.

We examine the role of self-shaping and commitment devices in persuasive systems. Self-shaping refers to the practice of taking purposeful action in modifying one's environment in order to shape or influence one's own future behavior. We present results from a survey of 23 users that assessed the role self-shaping plays in their use of persuasive technologies. A second survey elicited 65 self-shaping designs from 41 expert users, finding the Fogg Behavior Model describes how the designs were indeed persuasive. We then reviewed 85 tools based on this model to show the two dimensions that can be used to organize persuasive devices: (1) salience of a tool's self-shaping features and (2) their intended flexibility. The resulting four categories of tools are useful for researchers and designers of persuasive systems.
This paper addresses how children can collaborate by leveraging the ubiquity of mobile devices. Specifically we investigate how children (ages 8 - 9) read and share children's stories using two collaborative confi...
