Laptop Computers and the CCTV Video Magnifier
Using a Laptop Computer as a Portable Video Magnifier Display
Plan The Concept The Technology The Considerations The Tasks The Products The Concerns The Review The Trends The Resources
The Concept
Most students use laptop/notebook computers Video magnification could be helpful Portable camera using notebook display
The Concept
Multi-Task Computer, read, write, see at a distance
Classroom, Conferences, In-Service Training On-site activities; reports, forms, assessments
The Concept
Software required is available Image quality getting better More resources/choices available
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
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
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
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
Power
Computer system powered USB Percent of usage; 10% to 30% Drain
Battery powered Rechargeable Run time, recharge time Replaceable?
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
The Computer
Laptop (or desktop) Windows XP SP2, Vista Fast and powerful Memory
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)
USB Interface
Video to USB USB Connector from camera Video/USB Adaptor Part of power pack
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
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
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
Software Menus
Transportability
Size: base, arm, folding Weight Carrying Case
Special Backpack Laptop Case
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
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
The Considerations
User Interaction Setup: space, technical Camera mount if needed Use of controls: ergonomics Computer conflicts Information gathering Multitasking Transporting/Weight
The Considerations
Support/Service Warranty Local Representation/Tech
Support Repair Centers
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.
Distance ViewingIssues
Information gathering Classroom activities Short term tasks Image captures Intensive board work,
distracting Magnification/distance
Distance ViewingArea of View related to Magnification
Available Magnification
Distance Viewing
Camera aiming/tracking effort Information gathering
Screen Magnification Compatibility
Multi 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
