  • Courtroom Technology
    Courtroom Presentation Technology PowerPoint Storyboarding, Client Presentations & Courtroom Tech Paul J. Unger, Esq. ([email protected]) Copyright © 2018 by Paul J. Unger Introduction Attorneys under-utilize visual communication, and over-utilize verbal communication as compared to the general population.1 In one study, 387 attorneys and 1657 non-attorneys were surveyed over 3 years to determine how they fit into one of three learning/ communication styles: visual (seeing), auditory (speaking and hearing) or kinesthetic (feeling). 61% of the general population prefers to learn from visual information, while only 46.9% of attorneys prefer to communicate with visual information. Whether our audience is a group of attorneys, clients or jurors, it is clear that more attorneys than not prefer to not use visual information when presenting. This is a problem that must change. Whenever appropriate, we need to get attorneys and other presenters to supplement their presentations with visual information. MS PowerPoint (as well as Keynote and/or Prezi) are excellent tools to present that visual information. Unfortunately, most people grossly misuse PowerPoint and treat it as if it is the only tool in the presentation toolbox. 1 Animators at Law 2007 Study. Interestingly, according to this study, only 18% of non-attorneys learn best by hearing information, as compared to nearly 29% of attorneys. Presentation Technology Options There are many tools available that complement PowerPoint, and for good reason. PowerPoint cannot manage and display large numbers of images, documents and video with the flexibility many times needed in the courtroom. PowerPoint is very linear in nature, and was never designed to store, manage, retrieve and display a large number of images, document and video.

  • What Good Is a Linux Client?
    Preparing Today for Linux® Tomorrow What Good is a Linux Client? A Linux White Paper Preface Anyone who has followed the progress of Linux the past few years has noted the surprising gains that Linux has made in server operating system market share and “mindshare” against the entrenched opposition, notably Microsoft® Windows NT®, Novell Netware and various varieties of UNIX®. A complete Linux network, of course, would require Linux clients (networked PCs or terminals) as well. Therefore, an important question is, “Is Linux a viable desktop operating system for general business use?” or must we continue to be confined to the Windows world for our non-server needs? And what about laptop support, or a Small Office/Home Office (SOHO) user or home user, who does not need a network server? Is there a place for Linux in a stand-alone environment? These are some of the questions this paper addresses. I must confess that until recently I was merely a bystander watching with curiosity from the sidelines—without any real involvement— the progress Linux has made. So writing this paper not only gave me the excuse to join in on the action, but it also provides you with the perspective of a Linux “newbie” who is attempting to find the applications and utilities needed to create a working system. The conventional wisdom so far is that Linux is not “ready for prime time” as anything but a network operating system. We shall test this notion to see if I can find commercial, shareware and/or freeware programs for Linux to replace the existing applications I currently use with Windows.

  • I Use a Presentation Program
    ACCESSIBLE INSTRUCTION TIP SHEET I Use a Presentation Program Do you use PowerPoint slides in your lectures for students? All students benefit from an organized, clear, and concise PowerPoint presentation. These tips will help you make your PowerPoint presentations accessible to the greatest number of students and limit the amount of work you will need to do to make a PowerPoint presentation accessible to students with disabilities. What Makes an Accessible Slide Presentation? An accessible slide presentation is one that can be followed and understood by any student. It uses design features that make the presentation information easier for students with disabilities to perceive, understand and navigate, both in a classroom setting and when accessed electronically. This is especially true for persons using adaptive technology (AT) to compensate for a perceptual disability while performing tasks such as reading, operating a computer, etc. Examples of AT include: Screen readers - programs that enable users with perceptual disabilities to interact with computer content such as written text using auditory feedback and keyboard commands. Screen magnifiers - programs that enable users to magnify computer screen content, adapt the colour and contrast, make the mouse more visible, etc. General Tips Ensure that font size is sufficient; if your presentation will be viewed on a projector, font size may need to be larger (30 point font is suggested) Use high-contrast colours between the background and the text; if your presentation will be viewed on a projector, sometimes the contrast needs to be more pronounced. If you use colour, ensure they are contrasting. You can use the Grayscale option under View in Microsoft PowerPoint to test your colour combinations for sufficient contrast.
