2 Laptop Computers and CCTV Video Magnifiers PowerPoint Presentation Located at:

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

6 Laptop Computers and the CCTV Video Magnifier Using 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

23 Software Menus

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

25 The Considerations Laptop LCD Displays 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

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 Tasks Task 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 Viewing Issues 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
