Mobile learning has become very popular over the last few years. Smaller and more powerful devices that have become much easier to use made it possible to deliver innovative and more flexible services to learners. Especially smart phones which now, apart from cameras and music players, now also contain sensors like gyroscopes, GPS receivers, and a digital compass, cater for a number of innovative applications such as augmented reality.
Mobile technologies enable more flexibility for learners, freeing them from the desktop. Learning with mobile devices particularly serves work-based learning scenarios or field trips. But also the anytime anywhere aspect is most appealing to learners and teachers alike. Delivery of mobile content via e.g. ebooks provide learners with ubiquitous access to quality resources.
