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

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

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

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

  12. The Concept • Video camera images with Picture in Picture (PIP) • Image capture software • Media Center programs • Input: Video in, USB adapters • Without modifications • Limited image quality and response • Powered cameras (AC) • Max, MagniCam, OVAC • Prisma, Flipper • CamCorder

  13. The Concept • Special modified software/systems • 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

  14. 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

  15. The Cameras • General • Existing CCTV video cameras • Analog camera • Modified, Adapter, Connector • Abilities and limits • Specific • Special design for function/task

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

  17. 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

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

  19. Typical Requirements • Microsoft Windows XP Service Pack 2 • 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)

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

  21. The Software • Commercial • WinTV 2000 • WinAmp • TV tuner, Media Center • Proprietary • Clarity Capture • Opti • ClearNote • Zoom Ex

  22. 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

  23. 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

  24. Software Menus

  25. Demonstration • Max USB camera • Win TV 2000 software • ClearNote • Optelec software • PC Mate • Clarity capture software

  26. 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

  27. 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

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

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

  30. 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.

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

  32. Distance Viewing • Area of View related to Magnification • Available Magnification

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

  34. Screen MagnificationMulti Tasking • Typically, one or other, magnification on/off • Using magnification may enlarge video image • Video corruption • New compatibility with Screen Magnification Programs • Split screen • Currently Limited • New updates
