1 Laptop Computers and CCTV Video Magnifiers Using 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 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
Increased reading speed Increased duration Reduced visual effort Comfortable working position Adaptability Transportability Bulk Power Cost

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 Camera Power Source Laptop Computer
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 Specific/Specialty: Professional
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

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 Image Quality: Computer
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 Area of View related to Magnification Available Magnification
Distance Viewing Area of View related to Magnification Available Magnification

32 Distance Viewing Camera aiming/tracking effort Information gathering

33 Screen Magnification Compatibility Multi Tasking
