Atwood 617/306-9729, [email protected] by Stephen Atwood Editor-in-Chief: Jay Morreale This month, we take a look at the topic of tablets, ranging 212/460-9700, [email protected] from eReaders to holographic displays, but I want to start Managing Editor: Jenny Donelan with some observations on the topics of tablets, eReaders, 603/924-9628, [email protected] and other portable displays. We asked guest editor Jason Heikenfeld, Associate Professor & Director for the Novel Sales Manager: Christine von Steiger 413/783-0473, [email protected] Devices Laboratory at the School of Electronic and Com- puting Systems at the University of Cincinnati, to help us understand the latest product trends, as well as how the new devices would be used, and what the future looked like for these types of products. Jason assembled a nice Editorial Advisory Board lineup of perspectives we are pleased to feature this month. Stephen P. Atwood, Chair It is easy to be optimistic about this segment of the industry when you see the signif- Crane/Azonix Corp., U.S.A. icant adoption of eReaders, tablets, smartphones, and other similar devices appearing Helge Seetzen everywhere. I am on an airplane as I write this, and everyone around me is peering TandemLaunch Technologies, Westmont, into their tablet, smartphone, or eReader.

My fellow travelers are enjoying state-of-the-art touch screens Consultant, U.S.A. and almost unending battery life with much more space on their tray tables. There has clearly been a revolution in personal-computing technology. However, as much as it seems that the frontier of personal-computing devices has Guest Editors been conquered, some functionality still appears to be missing. For example, all of the Materials devices I can buy today use fixed, flat, rigid displays. The display dictates the physical Ion Bita, Qualcomm MEMS outline of the device and displays larger than about 5 in. on the diagonal relegate the Technologies device to a bag or purse for transport. eReaders and Tablets The entire time I have been working with ID magazine, we have been publishing Jason Heikenfeld, University of articles on flexible displays and trying to keep a balanced view between the hype of Cincinnati “just around the corner” and the pessimism of “that will never happen.” We have Backlighting/LEDs published numerous articles on the underlying technologies for flexible displays, Adi Abileah, Planar Systems carried various accounts about the supply chain and manufacturing technologies Interacting with Displays required, talked at length about the uncountable advantages of a display that can bend Geoff Walker, IMS Research or fold, and in some cases noted the loss of early-entry developers who tried and failed TV Technology to achieve the goal.

JOSÉ MARÍA CALÉS DE JUAN La Paz –Bolivia 2009 ii RESUMEN La motivación de éste trabajo nace como consecuencia de la observación de los dificultosos procesos de publicación de la producción intelectual y del posterior olvido de dichas producciones en anaqueles de las diferentes unidades de la Universidad Mayor de San Andrés (UMSA). La sociedad cuestiona el quehacer universitario y no tiene la forma de saber cuales son las actividades académicas y de investigación que se realizan en este tipo de instituciones. La difusión de la información en el tradicional formato de papel es costosa por los procesos de impresión, almacenamiento y distribución de dichas obras. Por otra parte la instalación de Nuevas Tecnologías de Información y Comunicación en la UMSA ofrece oportunidades poco conocidas para encarar soluciones más eficaces y eficientes en el proceso de difusión de la producción intelectual que conlleva un costo mucho menor y moderniza los procesos que a su vez son mucho mas versátiles que los antiguos métodos. El trabajo entonces inicia por hacer un análisis de las diferentes tecnologías de producción y despliegue de ebooks disponibles en el mercado. Se revisan tanto los productos de software como los de hardware desde el punto de vista de su evolución y su proyección futura de acuerdo a las tendencias mundiales en desarrollo.
