华盛顿大学的课堂演示讲座系统通过将标准的电子幻灯片演示格式与教师和学生使用平板电脑进行即兴墨水注释的功能相结合，实现了一个活跃的讲座环境。因此，它可以促进更多的互动，以学生为中心的学习。虽然许多学生可能拥有笔记本电脑，但很少有平板电脑设备。此外，演示者使用多播网络，这有可用性和可靠性问题。无处不在的演示器（UP）通过通用的网络技术扩展演示器，以支持非平板电脑观众并增强学生控制。UP使学生能够使用互联网浏览器(a)同步或异步查看教师播放的幻灯片和墨水，以及(b)通过覆盖在教师幻灯片上的文本提供上下文提交。唯一的妥协是，非平板电脑的学生不能生产墨水，而教授墨水是在一小段时间后提供的。
The University of Washington's Classroom Presenter lecturing system enables an active lecturing environment by combining a standard electronic slide presentation format with the capability for extemporaneous ink annotations by instructors and students using Tablet PCs. Thus, it can promote more interactive, student-centered learning. While many students may own laptops, few are yet Tablet devices. Also, Presenter uses multicast networking, which has availability and reliability issues. Ubiquitous Presenter (UP) expands Presenter via common web technologies to support non-Tablet audiences and enhance student control. UP enables students, using internet web browsers, to (a) synchronously or asynchronously view the slides and ink that are broadcast by the instructor, as well as (b) provide contextual submissions via text overlaid on the instructor's slides. The only compromises are that non-Tablet students cannot produce ink, and that professor ink is provided after a small time delay.
