  • It's Little Wonder That Longtime Windows Users Are Migrating in Droves to the New Mac
    Switching to the Mac: The Missing Manual, Tiger Edition By Adam Goldstein, David Pogue ............................................... Publisher: O'Reilly Pub Date: September 2005 ISBN: 0-596-00660-8 Pages: 520 Table of Contents | Index It's little wonder that longtime Windows users are migrating in droves to the new Mac. They're fed up with the virus-prone Windows way of life, and they're lured by Apple's well-deserved reputation for producing great all-around computers that are reliable, user-friendly, well designed, and now-- with the $500 Mac mini--extremely affordable, too. Whether you're drawn to the Mac's stability, its stunning digital media suite, or the fact that a whole computer can look and feel as slick as your iPod, you can quickly and easily become a Mac convert. But consider yourself warned: a Mac isn't just a Windows machine in a prettier box; it's a whole different animal and a whole new computing experience. If you're contemplating--or have already made--the switch from a Windows PC to a Mac, you need Switching to the Mac: The Missing Manual, Tiger Edition. This incomparable guide delivers what Apple doesn't: everything you need to know to successfully and painlessly move to a Mac. Missing Manual series creator and bestselling author David Pogue teams up with 17-year-old whiz kid and founder of GoldfishSoft (www.goldfishsoft.com) Adam Goldstein to cover every aspect of switching to a Mac--things like transferring email, files, and addresses from a PC to a Mac; getting acquainted with the Mac's interface; adapting to Mac versions of familiar programs (including Microsoft Office); setting up a network to share files with PCs and Macs; and using the printers, scanners, and other peripherals you already own.

  • Voice Input Computer Systems
    Voice Input Computer Systems AT Quick Reference Guide Computer Access Series Voice input computer systems (or speech recognition systems) learn how a particular user pronounces words and uses information about these speech patterns to guess what words are being spoken. Voice input systems are useful for the following problems: Trouble physically using the keyboard - Voice input systems can allow a person to operate a computer without using a keyboard or mouse. This can help people who are not able to use their hands at all, as well as others who can use their hands but are limited by speed, fatigue, or pain (e.g., carpal tunnel syndrome, one-handed keyboarders). Trouble creating text - Voice input systems can help a person, who has difficulty spelling words, create text. This can be particularly useful for some people with learning disabilities. However, the person's reading abilities need to be strong enough to recognize when the computer displays the wrong word. Tech Connections is a collaborative project of the United Cerebral Palsy Associations, the Center for Assistive Technology and Environmental Access at Georgia Tech., and the Southeast Disability and Business Technical Assistance Center. Funded by a grant from the National Institute on Disability and Rehabilitation Research of the Department of Education, Award #H133A980052. 490 Tenth St. NW, Atlanta, GA 30318 877-TEK-SEEK; Fax: 404-885-0641 FREQUENTLY ASKED QUESTIONS: How much does it cost? Most full systems cost about $200. For exact prices, check the manufacture web sites listed below. There are also several systems for less than $100, but these cheaper versions may not include all of the dictation features such as hands-free access or a text read-back feature.

Speech recognition (SR) systems allow people to control a computer by speaking to it through a micro- phone, either entering text, or issuing commands to the computer, e.g. to load a particular program, or to print a document. SR systems have been around for over twenty years, but the early systems were very expensive and required powerful computers to run. During recent years, manufacturers have released basic versions of their pro- grams selling for less than £50 and have also reduced the prices of the full versions. The technology behind speech output has also changed. Early systems used discrete speech, i.e. the user had to speak one word at a time, with a short pause between words. DragonDictate is the only discrete speech system still available commercially. Over the past few years most systems have used continuous speech, allowing the user to speak in a more natural way. The main continuous speech systems currently available for the PC are Dragon NaturallySpeaking and IBM ViaVoice. Microsoft have included their own speech recognition system within recent versions of Windows. There is now a version of IBM ViaVoice for recent Apple Mac computers. Hardware Issues At the same time as the software has been changing, computer prices have continued to drop and the power of a typical desktop machine has grown to such an extent that SR software will run on almost any standard PC manufactured in the past couple of years, provided that it has sufficient memory.

  • Usefulness of Artificial Intelligence-Based Virtual
    ORIGINAL RESEARCH Usefulness of Artificial Intelligence-based Virtual Assistants in Oral and Maxillofacial Radiology Report Writing Kavya S Muttanahally1, Rutvi Vyas2, Jyoti Mago3, Aditya Tadinada4 ABSTRACT Aim and objective: This study aimed to evaluate the usefulness of four voice-based virtual assistants in oral and maxillofacial radiology report writing. Materials and methods: A questionnaire consisting of 100 questions was queried to 4 commercially available voice-based virtual assistants namely Alexa, Siri, Cortana, and Google Assistant. The questions were divided based on five categories. The categorization was based on the frequency and reason for a radiologist to refer to either a textbook or an online resource before diagnosing and finalizing a radiology report. Two evaluators queried the devices and rated them on a 4-point modified Likert scale. Results: In the order of efficiency, Google Assistant was the most efficient followed by Cortana, Siri, and Alexa. A significant difference between the examiners was observed with Cortana in anatomy, dental anatomy, differential diagnosis, and pathology. Conclusion: In this small study that queried only four voice-powered virtual assistants, it showed that they were helpful and convenient in responding to questions regarding oral and maxillofacial radiology. But there is significant scope for expansion in the number of topics and type of information delivered before these can be used specifically in oral and maxillofacial radiology report writing. Clinical significance: Oral radiologists often gather additional and updated information regarding various topics like disease-specific features, genetic mutations, and differential diagnoses which they typically get from a textbook or a website. Artificial intelligence-based virtual assistants offer radiologists a simple voice-activated interface to gather this information and can immensely help when additional information is required.

Many readers might wonder why an advanced book such as this includes coverage of something as basic as the Windows user interface (UI). The decision was primarily driven by the knowledge that many users of Windows 7 will be upgrading from Windows 2000, XP, and even Vista. For those users, savvy as they might be with Windows concepts, the Windows 7 UI is different enough that they’ll need a roadmap to get started. When you are familiar with it, you’ll wonder how you ever got around in those old clunky environments. In addition to the newer look of Windows 7, many new functions are woven into the fabric of the new UI—we don’t want you to miss out on them. We’ve also included some UI tips and tricks that you might not know about. So even if you con- sider yourself a Windows veteran, at least take the time to skim through this chapter before you move on. Don’t just take our word for it. Experiment with the new UI as you read this chapter. We’ve found that nothing can substitute for direct hands- on operation to get an understanding and a feel for the new user envi- ronment.

  • Introduction to Computers
    Introduction to Computers 2 BASIC MOUSE FUNCTIONS To use Windows, you will need to operate the mouse properly. POINT: Move the mouse until the pointer rests on what you want to open or use on the screen. The form of the mouse will change depending on what you are asking it to look at in Windows, so you need to be aware of what it looks like before you click. SINGLE-CLICK: The left mouse button is used to indicate choices from menus and indicate choices of options within a “dialog box” while you are working in an application program. Roll the mouse pointer on top of the choice and press the left mouse button once. RIGHT-CLICK: With a single quick press on the right mouse button, it will bring up a shortcut menu, which will contain specific options depending on where the right-click occurred. CLICK AND DRAG: This is used for a number of functions including choosing text to format, moving items around the screen, and choosing options from menu bars. Roll the mouse pointer over the item, click and hold down the left mouse button, and drag the mouse while still holding the button until you get to the desired position on the screen. Then release the mouse button. DOUBLE-CLICK: This is used to choose an application program. Roll the mouse pointer on top of the icon (picture on the desktop or within a window) of the application program you want to choose and press the left mouse button twice very rapidly. This should bring you to the window with the icons for that software package.
