Accessing courses on a mobile device is more limiting then accessing courses from a PC. Before you create courses for a mobile devices it is important to clearly understand these limitations.
The most important issue to understand is the learners experience.
Mobile devices are typically used in a very distracted environment. Learners may be on a bus, on a train, at the store, eating lunch, or at work.
The mobile device screen is very small. This limits what the learner can see and can make it difficult to read a large amount of content, view graphics, or see moving graphics.
