E learning tools and technologies phần 2

(Vâng, chúng tôi có nghĩa là trò chơi.) Hầu hết các e-learning được bởi chỉ cần tốt mà không cần tăng tốc. Nếu bạn sử dụng rất nhiều hình ảnh động phức tạp, thế giới virtualreality, hoặc các chương trình mô phỏng khác, tuy nhiên, tăng tốc cải thiện độ mịn của màn hình hiển thị thị giác. | E-learning Tools and Technologies Hardware for e-learning 45 these items but without adequate video memory a learner may not be able to have high resolution high color depth and a high refresh rate at the same time. Acceleration Graphics cards boost the speed of display operations. This acceleration benefits complex video display operations such as rendering 3-D models or computing visibility of overlapping translucent objects. Yes we mean games. Most e-learning gets by just fine without acceleration. If you use a lot of complex animation virtual-reality worlds or other simulation programs however acceleration improves the smoothness of the visual display. Multimedia authors who create and edit multilayered Giving authore faster graphics or three-dimensional models will greatly displays will just benefit from an accelerated video card because they 5 desensltize themt o how their creations appear to will have to wait less time while their monitor display learners. redraws. For some applications this can be quite timeconsuming. Multiple monitor support From its third model on Macintosh computers allowed users to connect multiple monitors. Windows has recently added this capability. Now users who need more screen space can just attach more monitors provided they add extra display cards or their display card supports multiple monitors. Though not necessary for e-learners multiple monitors can be a boon for developers who use one monitor to edit their creations and another to view them the way learners will. Recommendations For e-learners you need to take three factors into consideration resolution color depth and refresh rate. To view e-learning and conduct other day-to-day activities a resolution of 1 024 x 768 is a safe choice. Specify a color-depth of at least 16 bits. This ensures that color graphics appear as intended with little or no color banding. Finally make sure that the video card can display the specified resolution and color depth and still achieve a .
