DreamBee Projector Released
Want an expensive projector that has a ridiculous contrast ratio? You'll spend $13,000 to $18,000. But DreamVision has released its DreamBee HD projector line, which includes the DreamBee and the DreamBee Pro. The DreamBees use D-ILA technology instead of DLP, and each model has a 3-chip light engine, multiple color presets, 1920x1080 resolution, and a 15,000-to-1 contrast ratio. The lamp is 1,000 lumens.
The Pro has four HDMI inputs and an external video processor. The DreamBee is 23 inches wide by 18.5 inches high by 8 inches deep, and weighs about 25 pounds, so it's not the most portable projector ever. For more information, go to www.dreamvision.net.
Presentation Zen Book Can Include Your Experience
Garr Reynolds, presentation guru and author of the popular presentations blog Presentation Zen, is finalizing a book that will be released this fall by Peachpit Press. The book, which is tentatively titled Presentation Zen, will cover the principles of presentation that distinguish good presentations from bad ones.
The book is partially based on Reynolds's blog, and Reynolds is using that blog to solicit the thoughts and insights of his readers. "If the material in the blog has been helpful at all for you I - d love to hear how," Reynolds writes. "What specific posts have been most useful (or useless) to you on the PZ blog? What success (or failure) stories do you have in applying the - PZ approac"H in your work? Do you have any slides (good or bad) that you can share? Your stories are important to me and I - d like to share them with a wider audience."
Reynolds's blog is at www.presentationzen.com.
New Book Offers Advice on PowerPoint
An expert in the workings of the visual brain has written a guide for using PowerPoint in a clear and psychologically effective manner. Clear and to the Point: 8 Psychological Principles for Compelling PowerPoint Presentations (Oxford University Press, 2007) was written by Stephen Kosslyn, a neuroscientist who has written several books on imagery, psychology, and the brain's workings. Kosslyn is currently the John Lindsley Professor of Psychology at Harvard University.
The book covers when to use different kinds of graphs and the proper use of color, among other suggestions for making presentations clearer and more effective.
