Xie, Bo, Yeh, Tom, Walsh, Greg, Watkins, Ivan and Huang, Man (2012): Co-designing an e-health tutorial for older adults. In: Proceedings of the 2012 iConference 2012. pp. 240-247.

Older adults' ability to access and use electronic health information is generally low, requiring innovative approaches for improvement. An integrated e-tutorial overlays instructions onto Websites. The literature suggests integrated e-tutorials are more effective than paper or video-based tutorials for younger people, but little is known about their effectiveness for older adults. This study explores the applicability of an integrated e-health tutorial for older adults. An integrated e-tutorial, the Online Tutorial Overlay Presenter (OnTOP), added an instructional overlay to the NIHSeniorHealth.gov Website. Overlay features were examined in seven participatory design sessions with seven older adults. Participatory design techniques were used to elicit participants' preferences for tutorial features. Three themes emerged: 1) using contextual cues; 2) tailoring to the learner's literacy level; and 3) enhancing interfaces with multimedia cues. These findings improved the design features of OnTOP. They also generated empirical evidence about the effects of multimedia learning among older adults.

Huang, Man, Hansen, Derek and Xie, Bo (2012): Older adults' online health information seeking behavior. In: Proceedings of the 2012 iConference 2012. pp. 338-345.

Over half of older adult Internet users search for health information online, a number likely to continue to climb. To design a better online environment for older adults, we need to understand how they search for health information online. In an observational study, 17 older adults aged from 56 to 78 completed four health related online search tasks. Through recordings of search activities, "think aloud" audio recorded data, interviews and questionnaires, we identified multiple key issues regarding older adults' search behavior for online health information, including: 1) using insufficient search queries to search for complex search constructs; 2) misunderstanding different Web browser and webpage search tools (e.g., address bar, search bar, webpage search boxes); 3) extensive reliance on prior knowledge in performing searches; and 4) a lack of ability to evaluate the quality of online health information. These findings have implications for developing design and educational interventions for older adults.

Yeh, Tom, Chang, Tsung-Hsiang, Xie, Bo, Walsh, Greg, Watkins, Ivan, Wongsuphasawat, Krist, Huang, Man, Davis, Larry S. and Bederson, Benjamin B. (2011): Creating contextual help for GUIs using screenshots. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 145-154.

Contextual help is effective for learning how to use GUIs by showing instructions and highlights on the actual interface rather than in a separate viewer. However, end-users and third-party tech support typically cannot create contextual help to assist other users because it requires programming skill and source code access. We present a creation tool for contextual help that allows users to apply common computer skills-taking screenshots and writing simple scripts. We perform pixel analysis on screenshots to make this tool applicable to a wide range of applications and platforms without source code access. We evaluated the tool's usability with three groups of participants: developers, instructors, and tech support. We further validated the applicability of our tool with 60 real tasks supported by the tech support of a university campus.

Xie, Bo, Watkins, Ivan and Huang, Man (2011): Making web-based multimedia health tutorials senior-friendly: design and training guidelines. In: Proceedings of the 2011 iConference 2011. pp. 230-237.

To better understand older adults' perceptions and use of Web-based multimedia features particularly in health-related content areas, we conducted a comparative usability testing of three Web-based multimedia health tutorials -- MedlinePlus Surgery Videos and MedlinePlus Interactive Tutorials both maintained by the National Institutes of Health (NIH), and Surgery Simulation (pseudo name) by a U.S.-based non-profit organization -- with 10 older adults in February-March of 2010. Data were collected from interviews, surveys, and observation carried out in three consecutive sessions. In this paper we report a subset of the key findings from our qualitative data, focusing on literacy-related challenges participants encountered when using the three sites. These challenges reflect gaps between the computer, medical, and numerical literacy levels that designers expected users to have and the literacy levels that these users actually have. Based on these findings and the multimedia learning literature, we recommend design and training guidelines that may facilitate older adults' learning and use of Web-based multimedia health tutorials.

Xie, Bo, Wang, Mo and Feldman, Robert (2011): Preferences for health information and decision-making: development of the Health Information Wants (HIW) questionnaire. In: Proceedings of the 2011 iConference 2011. pp. 273-280.

The Health Information Wants (HIW) Questionnaire was developed to measure 1) a broad range of the types and amount of each type of information health consumers want to have in dealing with health-related issues; and 2) the degree to which health consumers want to participate in each type of decision-making in each corresponding area. With parallel items in each corresponding area of information and decision-making, this instrument can reveal the relationship between information and decision-making preferences in each area. This paper reports the multi-stage development process of this instrument that lasted for over two years. This process included: 1) a grounded theory-driven exploratory study that identified the core framework; 2) initial item development based on the literature and the exploratory study; 3) content validity testing; 4) cognitive testing; and 5) a pilot study testing the psychometrics of the instrument.

Xie, Bo, Han, Peng and Shen, Ruimin (2004): PipeCF: a scalable DHT-based collaborative filtering recommendation system. In: Proceedings of the 2004 International Conference on the World Wide Web 2004. pp. 224-225.

Collaborative Filtering (CF) technique has proved to be one of the most successful techniques in recommendation systems in recent years. However, traditional centralized CF system has suffered from its shortage in scalability as their calculation complexity increases quickly both in time and space when the record in user database increases. In this paper, we propose a decentralized CF algorithm, called PipeCF, based on distributed hash table (DHT) method. We also propose two novel approaches to improve the scalability and prediction accuracy of DHT-based CF algorithm. The experimental data show that our DHT-based CF system has better prediction accuracy, efficiency and scalability than traditional CF systems.
