Improving e-Learning Environments for Pen and Multi-touch Based Interaction: A study case on blog tools and mobile devices

摘要

e-Learning environments are applications that use the Web infra-structure to support teaching and learning activities; they are designed to have good usability using a desktop computer with keyboard, mouse and high resolution medium-size display. Devices equipped with pen and touch sensitive screen have enough computational power to render Web pages and allow users to navigate through the e-learning environments. But, pen-based or touch sensitive devices have a different input style; decreasing the usability of e-learning environments due the interaction modality change. To work on mobile contexts, e-learning environments must be improved to consider the interaction through pen and touch. In a previous work, we presented the InkBlog, a blog tool that receives input data from pen allowing users to handwrite posts. In this work, we present an extension of InkBlog to receive input from multi-touch screens. We described the changes over the InkBlog architecture and implemented components to treat data generated by pen and touch.
