  1. Laptop Computers and CCTV Video Magnifiers 2008Using a Laptop Computer as a Portable Video Magnifier Display Robert McGillivray Certified Low Vision Therapist The Carroll Center f/t Blind Mass Commission f/t Blind

  2. Laptop Computers and CCTV Video MagnifiersPowerPoint Presentation Located at: www.carroll.org/resources

  3. Exhibit Area • Unique opportunity to see and compare technology • Review products with vendor • Ask competitor about products and alternatives • Explore other options • Get case studies, examples

  4. Increasing Visual Function • Magnification • Controlling lighting (brightness) • Enhancing contrast • Viewing skills

  5. Adaptability Transportability Bulk Power Cost Increased reading speed Increased duration Reduced visual effort Comfortable working position Traditional CCTV Video Magnifiers

  6. Laptop Computers and the CCTV Video MagnifierUsing a Laptop Computer as a Portable Video Magnifier Display

  7. Plan • The Concept • The Technology • The Considerations • The Tasks • The Products • The Concerns • The Review • The Trends • The Resources

  8. The Concept • Most students use laptop/notebook computers • Video magnification could be helpful • Portable camera using notebook display

  9. The Concept • Multi-Task • Computer, read, write, see at a distance • Classroom, Conferences, In-Service Training • On-site activities; reports, forms, assessments

  10. The Concept • Software required is available • Image quality getting better • More resources/choices available

  11. The Concept • Video camera images with Picture in Picture (PIP) • Image capture software • Media Center programs • Input: Video in, USB adapters • General Use: Off the Shelf • Limited image quality and response • Powered cameras (AC) • Max, MagniCam, OVAC • Prisma, Flipper • CamCorder

  12. The Concept • Special modified software/systems Professional • More acceptable image • Visual enhancement features • Keyboard controlled • USB powered cameras • USB operation gives portability • Some drain on laptop battery • Requirements • High performance computer • High performance video card

  13. The Technology • Video Camera • CCTV video magnifiers, others • Camera Power Source • USB, Battery, AC • Laptop Computer • Requirements • USB Interface/Adaptor • Video Imaging/Capture Software • Simple, Advanced, Complex • Transportability

  14. The Cameras • General Use: Off the Self • Existing CCTV video cameras • Analog camera • Modified, Adapter, Connector • Abilities and limits • Specific/Specialty: Professional • Special design for function/task

  15. Power • Computer system powered • USB • Percent of usage; 10% to 30% • Drain • Battery powered • Rechargeable • Run time, recharge time • Replaceable?

  16. Power • Built in battery pack • Part of camera, longer life • 4 hours to 10 hours • Auxiliary battery pack • Part of adapter, long life • Replaceable? • AC • Availability

  17. The Computer • Laptop (or desktop) • Windows XP SP2, Vista • Fast and powerful • Memory

  18. Typical Requirements • Microsoft Windows XP Service Pack 2 or Vista • Intel Celeron 2.0GHz (minimum) • Intel Pentium 4 1.6GHz (min) • AMD AthlonXP2400 or higher • USB-2 High Speed port(s) • 32MB Video RAM (64MB or more recommended) • 480MB RAM (min)

  19. USB Interface • Video to USB • USB Connector from camera • Video/USB Adaptor • Part of power pack

  20. The Software • Commercial/Off the Shelf • WinTV 2000 • WinAmp • TV tuner, Media Center • Proprietary/Specialty • Ash Tech Opti • Clarity Capture • Enhanced Vision USB Bridge • Freedom Scientific Eye Merge • HumanWare Graduate • Optelec ClearNote • Zoom Office

  21. Software • General Software Features • Full Screen, resizable Picture in Picture (PIP) • Always on Top • Image Control • Brightness, contrast, color, etc • Viewing Window • Window size, position, image menus, views • Image Capture: jpeg, bmp • Storage location, method

  22. Software • Advanced Software Features • Visual Enhancement • Controlling Software • Mouse • Keyboard • Combination • Camera control by keyboard • Magnification • Modes, colors • Markers • Setting views/presets, windows, enhanced images

  23. Software Menus

  24. Transportability • Size: base, arm, folding • Weight • Carrying Case • Special • Backpack • Laptop Case

  25. Thin, light weight for portability Flicker free High contrast Good color saturation Viewing angle (laptop, digital camera) Video response rate/times: Can be poor with moving images Games, Animation, Video Magnifiers, Screen magnification CCTV: low X, high reading rate Trends: faster response/rates The ConsiderationsLaptop LCD Displays

  26. The Considerations • Image Quality: Camera • Modes: B/W, W/B, HC, color • Range of magnification: low, high • Depth/range of focus • Ambient lighting: material, screen • Image Quality: Computer • Brightness level • Contrast • Image retention; static and moving • Processing display • Images of poor contrast material

  27. The Considerations • User Interaction • Setup: space, technical • Camera mount if needed • Use of controls: ergonomics • Computer conflicts • Information gathering • Multitasking • Transporting/Weight

  28. The Considerations • Support/Service • Warranty • Local Representation/Tech Support • Repair Centers

  29. The TasksTask Specific • General use, specific use • Primary, Secondary, Supplemental • Portability: worker, student, personal • Multi-Tasking: compute, near, desktop, intermediate & distance • Reading, writing, inspection, info gathering • Specific Needs: Student, social worker, lawyer, music student, lecturer, translator.

  30. Distance ViewingIssues • Information gathering • Classroom activities • Short term tasks • Image captures • Intensive board work, distracting • Magnification/distance

  31. Distance Viewing Area of View related to Magnification Available Magnification

  32. Distance Viewing • Camera aiming/tracking effort • Information gathering

  33. Screen Magnification CompatibilityMulti Tasking • Typically, one or other, magnification on/off • Using magnification may enlarge video image • Video corruption • New compatibility with Screen Magnification Programs • Split view allows simultaneous view of CCTV image and computer image • New updates
