Using Value-Added Visuals in E-Learning Using Value-Added Visuals in E-Learning
Overview • This presentation introduces some ways to create value-added visuals for e-learning and to employ these in the Axio Learning™ / Course Management System. Some examples will include photorealistic as well as imaginary imagery; diagrams and plans; conceptual models; scanned images, and microscopy images. This presentation will involve some analytical cases; some fictional cases; an e-book; some branding endeavors, and designed online learning environments. Strategies for adding value to digital imagery include: Using Value-Added Visuals in E-Learning
Overview (cont.) (1) strategic initial image captures (regarding still imagery color and size for proper perception; regarding sound and visual quality for video) (2) the proper selection of imagery (3) textual annotations of imagery; transcription and captioning of video (4) visual integration with the e-learning.

Your digital imagery in e-learning • Your experiences? • Your general uses? • Some general questions? Using Value-Added Visuals in E-Learning
Human vision • A “far sense” (vs. the near-senses of smell, taste, touch, and proprioception) • Capturing reflected light (off objects) and full spectrum light from above • Different wavelengths of light perceived as different colors based on the rods and cones in the • Diurnal (vs. nocturnal) humans (better vision in the day and worse in the night) • Saccadic eye movements • Gists of a scene • Attention and expectations, change blindness • Intrinsic light • Metamers Using Value-Added Visuals in E-Learning

From Image captures to deployment… Using Value-Added Visuals in E-Learning
Initial image captures • Born-digital or from-world (representational) • High-fidelity or low-fidelity • Realistic or symbolic • Low-stylized / raw or unprocessed or high-stylized / processed • Dynamic (moving) or static; continuous or static • Partial or holistic • Extreme visualizations: nano-size / mesoscale Using Value-Added Visuals in E-Learning
General capture concepts • The importance of setting and lighting • Sizing down is always preferable to sizing up, so capture the most visual information (the highest resolution) at the beginning • Use the right equipment…go high end… • Always test equipment (functions and settings) for visuals and sound captures • Practice with the equipment • Bring extras (equipment and batteries) • Always take multiple shots and captures for processing later (the relatively low-cost of the digital recording devices and the high-cost of recreating the setting) Using Value-Added Visuals in E-Learning
Image Capture equipment and software Equipment Software Equipment • Digital cameras • Camcorders • Scanners • Camera-mounted microscopes • Remote sensing, and other • Pen and tablets • Mobile phones and devices • Sensors and gauges • Computational photography (mix of sensors, optics, lighting, and combined strategies) • Software (stand-alone or embedded) • Drawing software / authoring tools Using Value-Added Visuals in E-Learning
Image capture • Proper light • Proper depth / sense of size • High visual information / high resolution captures • Clear focus • Clear angle • Inclusiveness of relevant visual information • White color balance / true color saturation and hue / the global adjustment of the intensities of the colors • Automated metadata (geolocation / more heavy-duty forensics on digital images); human-created metadata Using Value-Added Visuals in E-Learning
Image / visual rendering • Saving of a raw (“least lossy”) set • Naming protocols • Proper resolution (ppi / dpi) • Proper size (right-sizing) • Color balance / color output (“jumping color”) / color curves • Visual information preservation • File output type for particular use Using Value-Added Visuals in E-Learning
Image processing workflow Using Value-Added Visuals in E-Learning
The Selection of imagery • Provenance of the imagery • Raw (self-captured or open-source) and processed (commercial, open-source) • Multicultural / depictions • Legal considerations (intellectual property, privacy, libel, defamation, and accessibility) • Information richness • Learning context • Purposive uses of the imagery • Aesthetics Using Value-Added Visuals in E-Learning
Visual integration with e-learning • Information overlays (maps, databases of information) • Context (analysis, problem-solving) • Analytical depth • Sequencing of the learning • Unit of delivery (story, case, simulation, or environment?) Using Value-Added Visuals in E-Learning

What does “value-added” mean in terms of imagery? Using Value-Added Visuals in E-Learning
“Value-added” means… • Original imagery (unique or unavailable elsewhere) and perspective (point-of-view) • Clear provenance (origins) • All legal and “clean” (unencumbered) • Clear labeling and annotations (accessible) • High resolution and information-rich for data culling and analysis (visually informative) • Purposive design (i.e. memory, learner priming, reinforcement, emphasis, learning, experience, branding, storytelling, communications, analysis, and mood) • Image versatility for broad uses (such as cultural neutrality or cultural shaping) Using Value-Added Visuals in E-Learning
