An Experimental study of differences in reading photo books by presentation media: print vs. screen

As photography technology changes, the penetration of digital cameras is increasing, especially among young users. Compared to conventional camera users who print most of their images, digital camera users print about one-third of their digital images (PMA, 2009b, p. 10). Moreover, only 5 percent of camera phone users make photo prints (Henning, 2008, p. 4). One popular photo-finishing product is the photo book. The objective of this research was to determine whether people interacted differently with photographic content presented in print versus on screen. This research was focused on: 1. Time spent interacting with photo books. 2. Differences of recall and recognition by presentation modality. 3. Choices of medium preference. An experimental study was administered at RIT with 64 participants. Half were shown the printed book, and half were shown the PDF displayed on a computer monitor. The results showed that: 1. The average time spent interacting with the book was approximately 5 minutes for both printed book and screen views. There were no differences in the amount of time spent interacting with photographic content presented in print versus on screen. 2. There were no differences in how much participants remembered with photographic content presented on print versus on screen. 3. Overall, 74 percent of participants preferred to keep the printed book. However, relatively more participants selected the PDF when shown a PDF, even though the majority of participants overall selected the book

Print versus screen—presentation medium-dependent picture consumption

Part I: The use of digital technologies has forever changed how consumers are capturing, sharing, and storing their pictures. The long-term objective of Part I of this study is to obtain an overall picture of the current state of consumer photographers’ practices. While digital camera owners are taking more photos than ever before, most are not printing them. However, experiments conducted on the presentation mediumdependent differences in picture consumption showed that a majority of the participants prefer printed images to images viewed on a screen. Regardless of this preference, participants did not print images very often for a variety of reasons, including lack of time or money. In addition, results showed that the most commonly used printing tools included Kodak EasyShare Gallery, Shutterfly, and Flickr. Finally, participants cited Photoshop, Lightroom, and Picasa as the primary editing tools, with Facebook being mentioned as the main sharing tool. Parts II & III: The advent of digital print engines capable of achieving high image quality has opened up many new and exciting print product opportunities, including the short-run printing of magazines. However, content available for magazines is also readily available on-line. It is not immediately obvious that the capability of creating a short-run magazine translates into a viable business model; just because they can be printed does not necessarily mean that it makes sense to do so. The objective of this project was to take the first steps toward identifying and understanding the differences in how information is consumed from print on paper versus computer display and which characteristics of these media are particularly relevant in this comparison. Longer-term, it is intended to explore how such differences affect the efficacy of magazine advertising. This evaluation involved an assessment of differences for several metrics, including information retention, time taken to view images, preference for visually consuming information, and distribution of visual gaze as measured by eyetrackers. Experimentation was conducted that focused on the first three of these four factors (Part II). Experimentation in Part III generally confirmed the results of this study: specifically, that people preferred the hard copy rendition over a PDF when given the choice (for reasons of image accessibility and tangibility), and that neither the time used to view the photo books nor information retention as measured by image recognition and information recall were affected by the medium in which the photo book was seen. The results of this study also agreed with earlier research findings that observers tend to fixate first and most often in the central areas of images. This research also found, however, important differences between how the observers viewed the printed and screen versions of the photo book, with the screen group having more fixations per image for many of the images early in the book (though not spending more time with these images), while the print group switched more often between images. While the work conducted in Part II suggested that there were no important differences between the print and screen groups of observers, the results of Part III hint at differences that may be important with regard to individual images or image layouts. Further work involving image content with a more balanced mix of text and pictorial imagery might prove useful in exploring these findings further

An efficient management system for large digital object collections

Includes abstract.Includes bibliographical references (leaves 87-91)Cultures evolve continuously, and it is therefore vital to track and record these changes, and most importantly of all, manage the resulting huge mass of data such as images, video clips, audio recordings and documents. This thesis examines the design of a Web-based solution, hereafter referred to as the Information Management System (IMS), to handle the efficient, accurate and secure management of a large number of objects

The always best positioned paradigm for mobile indoor applications

In this dissertation, methods for personal positioning in outdoor and indoor environments are investigated. The Always Best Positioned paradigm, which has the goal of providing a preferably consistent self-positioning, will be defined. Furthermore, the localization toolkit LOCATO will be presented, which allows to easily realize positioning systems that follow the paradigm. New algorithms were developed, which particularly address the robustness of positioning systems with respect to the Always Best Positioned paradigm. With the help of this toolkit, three example positioning-systems were implemented, each designed for different applications and requirements: a low-cost system, which can be used in conjunction with user-adaptive public displays, a so-called opportunistic system, which enables positioning with room-level accuracy in any building that provides a WiFi infrastructure, and a high-accuracy system for instrumented environments, which works with active RFID tags and infrared beacons. Furthermore, a new and unique evaluation-method for positioning systems is presented, which uses step-accurate natural walking-traces as ground truth. Finally, six location based services will be presented, which were realized either with the tools provided by LOCATO or with one of the example positioning-systems.In dieser Doktorarbeit werden Methoden zur Personenpositionierung im Innen- und Außenbereich von Gebäuden untersucht. Es wird das ,,Always Best Positioned” Paradigma definiert, welches eine möglichst lückenlose Selbstpositionierung zum Ziel hat. Weiterhin wird die Lokalisierungsplattform LOCATO vorgestellt, welche eine einfache Umsetzung von Positionierungssystemen ermöglicht. Hierzu wurden neue Algorithmen entwickelt, welche gezielt die Robustheit von Positionierungssystemen unter Berücksichtigung des ,,Always Best Positioned” Paradigmas angehen. Mit Hilfe dieser Plattform wurden drei Beispiel Positionierungssysteme entwickelt, welche unterschiedliche Einsatzgebiete berücksichtigen: Ein kostengünstiges System, das im Zusammenhang mit benutzeradaptiven öffentlichen Bildschirmen benutzt werden kann; ein sogenanntes opportunistisches Positionierungssystem, welches eine raumgenaue Positionierung in allen Gebäuden mit WLAN-Infrastruktur ermöglicht, sowie ein metergenaues Positionierungssystem, welches mit Hilfe einer Instrumentierung aus aktiven RFID-Tags und Infrarot-Baken arbeitet. Weiterhin wird erstmalig eine Positionierungsevaluation vorgestellt, welche schrittgenaue, natürliche Bewegungspfade als Referenzsystem einsetzt. Im Abschluss werden 6 lokationsbasierte Dienste vorgestellt, welche entweder mit Hilfe von LOCATO oder mit Hilfe einer der drei Beispiel-Positionierungssysteme entwickelt wurden

Snap and share your photobooks

The sharing of photos with others, friends and family, has become even more popular with digital photography and Internet applications such as email or Web albums. At the same time, the physical touch of printed photos is still appreciated and customers use different services to print their photos on post cards, calendars or photobooks, often to give them as a present or to create a physical souvenir. Once printed, however, the sharing of photos with others becomes difficult as there is no link back from the now physical item to its digital counterpart. With Bookmarkr, we developed a system that employs a mobile camera phone to bridge the gap between the printed photo and its digital counterpart. The user takes an image of a photo in a photobook with the mobile phone’s camera. The image is transmitted to a photobook server, which employs image analysis techniques to retrieve the corresponding photo. The photo is sent back to the user and establishes the digital-physical match. Bookmarkr allows the user to interact with printed photos in a similar way as interacting with digital photos by using a point-and-shoot metaphor. Our performance evaluation shows that the system is able to return the correct photo in up to 99 % of all cases. A conducted user study revealed that the designed interaction is suitable for the participants and their printed photobooks
