Laptop Computers and the CCTV Video MagnifierUsing 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
Transportability • Size: base, arm, folding • Weight • Carrying Case • Special • Backpack • Laptop Case
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
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 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.
Distance ViewingIssues • Information gathering • Classroom activities • Short term tasks • Image captures • Intensive board work, distracting • Magnification/distance
Distance Viewing Area of View related to Magnification Available Magnification
Distance Viewing • Camera aiming/tracking effort • Information gathering
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
