PartoPen: Enhancing the Partograph with Digital Pen Technology -
Student Research CompetitionContribution & Benefit: PartoPen is an interactive digital pen-based system that reinforces birth-attendant training, records labor progress, validates form data, and overall, aims to improve maternal outcomes in developing countries.
Abstract » Existing paper-based systems for monitoring maternal labor have been shown to reduce life-threatening complications in low-resource environments; however, significant barriers exist to their use in developing countries. In this paper I describe a system that enhances a common labor-monitoring form, the partograph, using a digital pen. The digital partograph system provides real-time data feedback and reinforces birth attendant training, while retaining the paper-and-pen interface currently used by most healthcare workers. The system is currently being evaluated in Kenya.
SocialProof: Using Crowdsourcing for Correcting Errors to Improve Speech Based Dictation Experiences -
Student Research CompetitionContribution & Benefit: SocialProof, a crowdsourcing powered automatic speech recognition (ASR) enhancement to reduce error correction efforts, is proposed to provide a powerful, accurate and cost-effective ASR dictation system.
Abstract » Though various Automatic Speech Recognition (ASR) based text correction techniques have been proposed, it is still difficult to correct dictation errors using speech based commands. Inspired by the successful use of crowdsourcing to solve computation tasks, we propose SocialProof, a crowdsourcing powered ASR dictation enhancement, to provide a powerful and accurate but fairly cheap ASR dictation system. SocialProof begins with the output produced by ASR engines and enhances this output using the power of crowd intelligence via MTurk service. Our system splits one ASR dictation scenario into several smaller tasks, allowing multiple people to work on different pieces of the task at the same time. Data merging strategies are used to combine multiple responses from MTurk workers to provide improved results. An evaluation of SocialProof strongly supports the effectiveness of this approach.
A Framework for Interactive Paper-craft System -
Student Research CompetitionContribution & Benefit: In this paper I present three main characteristics for paper-computing system, as an initial framework for designing paper-computing interaction, with two supportive technologies: natural-feature-based origami recognition and selective inductive power transferring.
Abstract » Paper, as a tradition medium for art and communication, shows great potential as a good candidate for organic user interface (OUI), with its intrinsic deformability and flexibility. In this paper I present the analysis of the user behaviors while playing paper-craft, such as writing, drawing, folding, cutting, gluing, etc. Then I derive three main characteristics for paper-computing system, as an initial framework for designing paper-computing interaction. Furthermore, two supportive technologies were developed: natural-feature-based origami recognition and selective inductive power transferring. With these two technologies, users could easily design and implement paper-computing systems which fullfill the three characteristics in the proposed framework. Finally, an interactive system for physical origami sharing through internet is developed by using these two technologies and the presented framework.
ScreenMatch: Providing Context to Software Translators by Displaying Screenshots -
Student Research CompetitionContribution & Benefit: ScreenMatch provides software translators with visual context for each translatable message, by matching each message with a corresponding screenshot of the application.
Abstract » Translators often encounter ambiguous messages while translating software. To resolve ambiguity, the translator needs to understand the context in which the message appears. Currently, context is provided via textual descriptions, or not at all. This paper describes ScreenMatch, a system which provides translators with visual context for each translatable message. It does so by matching each message with a corresponding screenshot of the application. ScreenMatch consists of a tool to gather screenshots, an algorithm to match messages to screenshots, and an interface that presents translators with screenshots alongside messages. We evaluated the system by gathering screenshots for 3 applications, using the algorithm to match messages to screenshots, and comparing results to manual matches. We found that hard-to-reproduce error messages make it difficult to gather all the screenshots. The algorithm correctly matched messages to screenshots 80% of the time when a corresponding screenshot had been gathered.
Mobile Continuous Reading -
Student Research CompetitionContribution & Benefit: This research focuses on mobile continuous reading under frequent context switching while reading web pages. This paper presents the results of a user study with 10 users.
Abstract » This research focuses on mobile continuous reading under frequent context switching while reading web pages. This paper presents the results of a user study with 10 users. Four conditions were investigated in the study: visual-reading, audio-listening, manual-switching between visual and audio, and auto-switching between them. The results showed that auto-switching not only provides the easiest reading experience, but it also results in significantly fewer missteps while walking, compared with visual-reading.
Symbolic Documentation: Toward Fashion-related Sustainable Design -
Student Research CompetitionContribution & Benefit: This work focuses on exploring and identifying the role of fashion in digital consumption, and how fashion and sustainability could and might interplay in the IT industry.
Abstract » In this paper, I present ongoing research on fashion-related sustainable interaction design. This work focuses on exploring and identifying the role of fashion in people’s acquisition of objects, especially digital and electronic devices, and how fashion and sustainability could and might interplay in the IT industry. In what follows, I first describe the background and related research apropos of sustainability and fashion within HCI literature. Then, I present the early findings from an ongoing empirical study, which involves a method of symbolic documentation and collection of digital objects. I conclude by articulating several design implications that can serve as a catalyst to embed the notion of fashion in sustainable interaction design.
Impact of Platform Design on Cross-language Information Exchange -
Student Research CompetitionContribution & Benefit: Design affects the sharing of information between human languages on international platforms with user-generated content. This study compares off-site link sharing on Wikipedia and Twitter following the 2011 Japanese earthquake.
Abstract » This paper describes two case studies examining the impact of platform design on cross-language communications. The sharing of off-site hyperlinks between language editions of Wikipedia and between users on Twitter with different languages in their user descriptions are analyzed and compared in the context of the 2011 Tohoku earthquake and tsunami in Japan. The paper finds that a greater number of links are shared across languages on Twitter, while a higher percentage of links are shared between Wikipedia articles. The higher percentage of links being shared on Wikipedia is attributed to the persistence of links and the ability for users to link articles on the same topic together across languages.
Personal Task Management: My Tools Fall Apart When I’m Very busy! -
Student Research CompetitionContribution & Benefit: The material highlights three important points: factors that influence personal task management behavior; main challenges facing busy people; the adequacy of existing tools and design recommendations for improving them.
Abstract » Existing applications tend to highlight tasks that people should be doing at any given time based on the parameters of urgency (e.g. deadline), assigned priority and reminders. Our field studies demonstrate that people consider existing applications as inadequate to flexibly adapt to current changes in other essential factors, including, task size, complexity and interdependency and the unexpected situations that people face over time. Another key challenge facing busy people is that there is no mechanism that can monitor their work habits and match their tasks with their time constraints. Grounded in our data, we propose important requirements for tools that support users in managing tasks and assessing their schedules.
Third-Party Applications’ Data Practices on Facebook -
Student Research CompetitionAbstract » The objective of this study is to better understand the information exchange created between social networking sites and third-party applications. Toward this end, I have collected data from the 29,020 most popular social applications on Facebook. I have analyzed the general distribution patterns of applications in terms of what types of interfaces they will present to users when users wish to add them to their profile as well as the scope of information that applications can potentially collect from users of Facebook. To further explore the ways in which third-party applications collect users’ information, I am currently conducting data analysis to identify permissions that tend to bundle together, permission collecting patterns that exist in different categories of applications, and the information collecting patterns of large developers versus smaller developers.
A Multi-user Collaborative Space for Architectural Design Reviews -
Student Research CompetitionContribution & Benefit: Describes an interaction modality using depth sensors for collaboration and communication of designs. Can help architects to better interact with each other with the building design as the central theme.
Abstract » I present a multi-touch multi-user collaborative design review space for architectural practice. With the advent of 3D visual programming systems, abstract graphical representations of the algorithmic processes that generate the geometry of a building have become a subject of discussion. These discussions require collaboration among many professions. The system presented in this paper provides an interactive interface for navigation and editing of a Grasshopper visual programming “canvas” for the Rhinoceros 3D modeling program. It uses a tabletop display of the Grasshopper canvas and touch-based input for navigation and manipulation of algorithmic components. A wall-projected display provides synchronized real-time visualization of the 3D model. The aim of the interface is to facilitate dynamic decision-making, increase team understanding and provide an integrated environment for collaborative interaction with parametrically driven designs.
