SeeReader: An (Almost) Eyes-Free Mobile Rich Document Viewer
Reading documents on mobile devices is challenging. Not only are screens small and difficult to read, but also navigating an environment using limited visual attention can be difficult and potentially dangerous. Reading content aloud using text-to-speech (TTS) processing can mitigate these problems, but only for content that does not include rich visual information. In this paper, we introduce a new technique, SeeReader, that combines TTS with automatic content recognition and document presentation control that allows users to listen to documents while also being notified of important visual content. Together, these services allow users to read rich documents on mobile devices while maintaining awareness of their visual environment
SurfaceConstellations: A Modular Hardware Platform for Ad-Hoc Reconfigurable Cross-Device Workspaces
We contribute SurfaceConstellations, a modular hardware platform for linking multiple mobile devices to easily create novel cross-device workspace environments. Our platform combines the advantages of multi-monitor workspaces and multi-surface environments with the flexibility and extensibility of more recent cross-device setups. The SurfaceConstellations platform includes a comprehensive library of 3D-printed link modules to connect and arrange tablets into new workspaces, several strategies for designing setups, and a visual configuration tool for automatically generating link modules. We contribute a detailed design space of cross-device workspaces, a technique for capacitive links between tablets for automatic recognition of connected devices, designs of flexible joint connections, detailed explanations of the physical design of 3D printed brackets and support structures, and the design of a web-based tool for creating new SurfaceConstellation setups
Electronic Environments for Reading: An Annotated Bibliography of Pertinent Hardware and Software
In the development of new research environments, hardware has often been neglected. E-readers have (reasonably) successfully been developed for leisurely reading, but reading with the goal of writing demands a different approach. This bibliography has been written to inform the INKE research group on physical aspects of digital scholarly reading. It consists of two parts: a hardware section, including a description of commercial e-readers as well as an overview of academically developed digital reading devices and a software section, also including commercially available packages next to academically developed reading environments which allow for flexible manipulation of text and other modalities; as well as reflections on digital scholarly reading. Combined, the two sections inform an integrated approach in the development of new research environments

Educational use cases from a shared exploration of e-books and iPads
E-books and e-book readers are becoming increasingly widely available, particularly for the general reader, and there have been many studies on their adoption. However, less is known about their use for educational and academic purposes. We report here on work carried out on e-books and e-book applications using iPads by academic and teaching staff. After considering pedagogical issues and reporting survey results, we identify a spiral of six key use case areas for e-books. This spiral of use cases moves from basic e-book use, through situational reading, e-books and learning, using multiple learning resources, collaborative/group learning, to e-book production. We discuss each of these use case areas and provide guidelines that will be of interest to practitioners and researchers alike
Web page enhancement on desktop and mobile browsers
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, February 2013."February 2013." Cataloged from PDF version of thesis.Includes bibliographical references (p. 154-165).The Web is a convenient platform to deliver information, but reading web pages is not as easy as it was in 1990s. This thesis focuses on investigating techniques to enhance web pages on desktop and mobile browsers for two specific populations: non-native English readers and mobile users. There are three issues addressed in this thesis: web page readability, web page skimmability and continuous reading support on mobile devices. On today's primarily English-language Web, non-native readers encounter some problems, even if they have some fluency in English. This thesis focuses on content presentation and proposes a new transformation method, Jenga Format, to enhance web page readability. A user study with 30 non-native users showed that Jenga transformation not only improved reading comprehension, but also made the web page reading easier. On the other hand, readability research has found that average reading times for non-native readers has remained the same or even worse. This thesis studies this issue and proposes Froggy GX (Generation neXt) to improve reading under time constraints. A user study with 20 non-native users showed that Froggy GX not only enhanced reading comprehension under time constraints, but also provided higher user satisfaction than reading unaided. When using the Web on mobile devices, the reading situation becomes challenging. Even worse, context switches, such as from walking to sitting, static standing, or hands-free situations like driving, happen in reading in on-the-go situations, but this scenario was not adequately addressed in previous studies. This thesis investigates this scenario and proposes a new mobile browser, Read4Me, to support continuous reading on a mobile device. A user study with 10 mobile users showed that auto-switching not only provided significantly fewer dangerous encounters than visual-reading, but also provided the best reading experience.by Chen-Hsiang Yu.Ph.D

The Use of Multiple Slate Devices to Support Active Reading Activities
Reading activities in the classroom and workplace occur predominantly on paper. Since existing electronic devices do not support these reading activities as well as paper, users have difficulty taking full advantage of the affordances of electronic documents.
This dissertation makes three main contributions toward supporting active reading electronically. The first contribution is a comprehensive set of active reading requirements, drawn from three decades of research into reading processes. These requirements explain why existing devices are inadequate for supporting active reading activities.
The second contribution is a multi-slate reading system that more completely supports the active reading requirements above. Researchers believe the suitability of paper for active reading is largely due to the fact it distributes content across different sheets of paper, which are capable of displaying information as well as capturing input. The multi-slate approach draws inspiration from the independent reading and writing surfaces that paper provides, to blend the beneficial features of e-book readers, tablets, PCs, and tabletop computers.
The development of the multi-slate system began with the Dual-Display E-book, which used two screens to provide richer navigation capabilities than a single-screen device. Following the success of the Dual-Display E-book, the United Slates, a general-purpose reading system consisting of an extensible number of slates, was created. The United Slates consisted of custom slate hardware, specialized interactions that enabled the slates to be used cooperatively, and a cloud-based infrastructure that robustly integrated the slates with users' existing computing devices and workflow.
The third contribution is a series of evaluations that characterized reading with multiple slates. A laboratory study with 12 participants compared the relative merits of paper and electronic reading surfaces. One month long in-situ deployments of the United Slates with graduate students in the humanities found the multi-slate configuration to be highly effective for reading. The United Slates system delivered desirable paper-like qualities that included enhanced reading engagement, ease of navigation, and peace-of-mind while also providing superior electronic functionality. The positive feedback suggests that the multi-slate configuration is a desirable method for supporting active reading activities

Spatial peripheral interaction techniques for viewing and manipulating off-screen digital content
When an information space is larger than the display, it is typical for interfaces to only support interacting with content that is rendered within its viewport. To support interacting with off-screen content, our work explores the design and evaluation of several spatial off-screen exploration techniques that make use of the interaction space around the display. These include Paper Distortion, Dynamic Distortion, Dynamic Peephole Inset, Spatial Panning, and Point2Pan. We also contribute a formalized descriptive framework of the off-screen interaction space that divides the around-device space into interaction volumes and analyzes them based on different factors. This framework guided the design of an off-screen interaction system, called Off-Screen Desktop, which implemented our spatial techniques using consumer-level motion sensing hardware. To enable a more detailed analysis of spatial interaction systems, we also developed a web-based visualization system, called SpatialVis, that visualizes log data over a video screen capture of the associated user interface
Navigation Techniques for Dual-Display E-Book Readers
Existing e-book readers do not do a good job supporting many reading tasks that people perform, as ethnographers report that when reading, people frequently read from multiple display surfaces. In this paper we present our design of a dual-display e-book reader and explore how it can be used to interact with electronic documents. Our design supports embodied interactions like folding, flipping, and fanning for local/lightweight navigation. We also show how mechanisms like Space Filling Thumbnails can use the increased display space to aid global navigation. Lastly, the detachable faces in our design can facilitate inter-document operations and flexible layout of documents in the workspace. Semi-directed interviews with seven users found that dual-displays have the potential to improve the reading experience by supporting several local navigation tasks better than a single display device. Users also identified many reading tasks for which the device would be valuable. Users did not find the embodied interface particularly useful when reading in our controlled lab setting, however.
