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
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 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
Dolphin Products • Lunar, Lunar Plus, SuperNova • Compatible with a range of digital CCTVs • Optelec ClearNote • LVI Student • Ash Tech OPTi • May need upgrades
Zoomtext • ZT V9.04 update Nov 2006 • CCTV USB compatibility • Split view allows simultaneous view of CCTV image and ZT • Need software update from CCTV vendor • 2 Vendors have implemented • Optelec ClearNote • LVI Student • Other working on it • Ash, Clarity, Optron, Synsupport
