This document discusses different types of characters that can be used in e-learning, including doodles, pictograms, humanoids, icons, silhouettes, cliparts, and cut out people. Doodles and stick figures are simple drawings that can represent characters with limited time and budget. Pictograms are custom characters made from basic shapes that are easy to understand visually. Humanoids are 3D characters that are gender and race neutral and allow for easy editing. Icons should be easily understood at a glance. Silhouettes focus learner attention on content. Cliparts provide inexpensive images while cut out people make courses more engaging through character packs with different poses.
