Orientation tactics and associated factors in the digital library environment: Comparison between blind and sighted users

This study investigates types of tactics that blind and sighted users applied in their initial exploration with a digital library (DL). Sixty participants with 30 blind and 30 sighted novice users were recruited for the study. Multiple data collection methods were employed to collect data: questionnaires, think-aloud protocols, and transaction logs. The findings of the study show that sighted participants focused on browsing DL content when blind participants concentrated on browsing DL structure. As the first study of its kind, it has both theoretical and practical implications.

Tactics Applied by Blind and Sighted Users: Initial Exploration of a Digital Library

A feature-oriented analysis of developers' descriptions and user reviews of top mHealth applications for diabetes and hypertension.

The authors conducted the first study to investigate the types of coping tactics that blind and visually impaired (BVI) users applied when they encountered difficulties interacting with digital libraries (DLs). Coping tactics are defined as diverse action choices used by BVI users to accomplish specific goals in response to different types of help-seeking situations. Sixty-four participants were recruited throughout the United States. Multiple data collection methods were employed to collect data: pre-questionnaires, think-aloud protocols, transaction logs, and diaries. The study identified 19 types of coping tactics associated with the top five help-seeking situations. The findings were further compared with prior research to highlight the tactics previously identified from non-DL environments and unique coping tactics found only in the DL context. On the one hand, BVI participants brought their 11 types of coping tactics from non-DL environments into the DL context. Among them, Searching for keywords and Seeking human help are the coping tactics employed to address all of the top five situations in the DL environment. On the other hand, the combination of structural complexity, use of multimedia formats, and sight-centered designs found in DLs force BVI users to apply eight unique coping tactics in the DL context. The linear way of going through the DL structure led BVI users to explore DL page structure. At the same time, they had to Explore an accessible alternative to deal with inaccessible multimedia content. To support the coping tactics adopted from non-DL environments, the design suggestions focus on directly resolving situations, offering more options within DLs, and creating or enhancing features based on BVI users’ coping tactics. To support the unique coping tactics, the design implications concentrate on ways of reducing help-seeking situations.

Coping tactics of blind and visually impaired users: Responding to help-seeking situations in the digital library environment

This study was conducted to understand how key stakeholders perceive the importance of design guidelines that specifically target the needs of blind and visually impaired (BVI) digital library (DL) users. An in-depth survey questionnaire was distributed among 150 participants representing three stakeholder groups: BVI users, DL developers, and scholars/experts. Participants were informed about different help-seeking situations that BVI users encountered when interacting with a DL non-visually using screen readers. They were then presented with a set of design guidelines to address each situation. Finally, they were asked to rate the importance of each set of guidelines in remediating each corresponding situation. Both quantitative analysis and qualitative analysis were applied to analyze the data. The results show that all key stakeholders agree it is critical to develop DL design guidelines to support BVI users. On the one hand, the three groups share some similarities in rating the importance of guidelines for these help-seeking situations; on the other hand, the disparities mainly lie in the fact that DL developers and the scholars/experts focused more on the guidelines addressing the accessibility-related situations, while BVI users emphasized that DL design guidelines need to take into consideration both accessibility and usability-related situations.
