  3. Plan • Explore some newer and unique devices • Discuss characteristics and considerations • Identify trends • Review resources

  4. Desktop systems Variable Magnification Color, W/B, B/W Large Field of View Options Increased reading speed Increased duration Reduced visual effort Comfortable working position Traditional CCTV Video Magnifiers

  5. Trends in Video Magnifiers:Desktop Units • Integrated LCD displays • Color, Auto Focus • Adjustable height screens • Faster Response Rates • Screen sizes: Standard, Widescreens • Transportable Classroom, distance viewing • Laptop Compatible systems

  6. Trends in Video Magnifiers: Compact Systems • Compact/pocket video magnifiers • New features, designs • Variable Magnification • Batteries improvements • Ultra-compacts • Small size • Replacement for Optical magnifier? • Less Expensive

  7. Newer Desktop Video MagnifiersIntegrated LCD Displays • Available from all major vendors • Sizes: 17” to 22” + with WS • Adjustable height screens • High contrast • Flicker free • Improved response rates • Well received by consumers

  8. Newer Desktop Video MagnifiersIntegrated LCD SystemsConsiderations • Image retention problems for some at low magnification • Costs • Stand by mode • Cleaning the screen

  9. Newer Desktop Video MagnifiersLCD Display Aspect Ratios • Bigger screens gives more magnification? • Not necessarily! • Standard Aspect 4:3 (older TVs, current & older CCTVs) • Widescreen (WS) aspect 16:9 (newer designs) • Comparing Standard to WS, apples to oranges

  10. Newer Desktop Video MagnifiersLCD Display Aspect Ratios • Screens are measured diagonally • A 22” WS will give a wider image than a 19” Standard but may be equal in screen height • Limited vertical magnification, only stretching the width • Characters may be wider and more spaced but not much taller.

  11. Newer Desktop Video MagnifiersLCD Display Aspect Ratios • Currently both ratios are available so be cautious in thinking a larger screen will give you a larger image. • Soon it is expected that only widescreen systems will be available. That may reduce the confusion.

  12. Newer Desktop Video MagnifiersIntegrated LCD Displays • Freedom Scientific Topaz • Telesensory Apex • Enhanced Vision Merlin LCD • Magnisight Journey Optelec • ClearView Plus • HumanWare Extend • Vision Technology Inc. • Others
