InkBlog: A Pen-Based Blog Tool for e-Learning Environments

  1. 1. InkBlog A Pen-Based Blog Tool for e-Learning Environments André C. da Silva1,2 Heloísa V. da Rocha1,3 acsilva@ic.unicamp.br heloisa@ic.unicamp.br Ph.D. Student Advisor 1Institute of Computing and 3NIED / UNICAMP 2Federal Institute of São Paulo São Paulo – Brazil InSITE 2013 Porto, Portugal - July, 3rd 2013
  2. 2. Outline ● Introduction – Blogs, Weblogs and Edublogs – Pen-based computing ● Motivation ● Approach – The InkBlog ● Final Considerations and Future Works
  3. 3. Introduction ● Weblog – communication and collaborative tool disposed in Web that aims to promote the sharing of messages among participants through an area named blog ● Users can publish text, images, videos, audio and links – Posts typically displayed in reverse chronological order ● the most recent post appears first – Allow visitors to leave comments
  4. 4. Introduction ● Edublog – Blogs used as instructional resources – archive and support student and teacher learning by facilitating reflection, questioning by self and others, collaboration and by providing contexts for engaging in higher-order thinking (Ray, 2006)
  5. 5. Introduction
  6. 6. Introduction ● Blogs and e-Learning environments – Each course participant (student or teacher) owns a blog, where the user can post and manage messages – Each participant may access other course participants’ blogs, comment posted messages by the owner of the blog – Usually, the users interact with in a text editor that allows users without HTML (HyperText Markup Language) skills to write rich text

  9. 9. Introduction ● Design process:
  10. 10. Introduction
  11. 11. Motivation ● Just changing the interaction hardware (da Silva, Freire, & da Rocha, 2013) : – brings interaction problems – does not take advantages of the interaction style features
  12. 12. Motivation ● For example, in the blog case: ● Users needs typing the text using the pen in a virtual keyboard – Low efficient – A boring task – Do not take the mainly pen purpose: handwriting and do sketches easily Prejudice the usability
  13. 13. Pen-Based Computing (I) ● Refers to a computer user-interface using a pen, rather than devices such as a keyboard or a mouse ● User interfaces for pen computing can be implemented in several ways: – using the pen as a pointing input device – considering direct manipulation, handwriting or gesture recognition (better advantages)
  14. 14. Pen-Based Computing (II) ● Berque, Bonebright and Whitesell (2004) – “these concepts [from computer science curriculum] are very difficult to communicate quickly and extemporaneously using a keyboard and they are also difficult to describe orally” ● Florea and Radu (2007) – concept maps to improve the quality and efficiency of the instructional process ● Benlloch, Buendía and Cano (2009) – six steps based on a teaching method that incorporates active learning techniques
  15. 15. Pen-Based Computing (III) ● Backon (2006) – “the keyboard allows a rapid typewriting and do texts structured by topics, but only pen can allow a creativity increment, better flexibility and a natural record of the think development process and rationale in all stages (ideal requirements for the educational environment)”
  16. 16. Pen-Based Computing (IV) ● Some educational applications: – OrganicPad (Pargas et al., 2007) – MathBrush (Labahn et al., 2008) ● “entering mathematics on a computer is problematic, it is more natural write the formulae than inputting the latex form, maple form or mathematic form” – Classroom Presenter (Anderson et al., 2007) – Pen Annotation and @Graph (Florea and Radu, 2007) – … All limited to the Tablet PC platform
  17. 17. Research Question ● How to get the pen computing advantages in Web tools, mainly in e-Learning environments? – Users with pen-based devices, such as tablet, can access Weblogs and easily read the posts, but writing blog post is not too easy: the user needs to type the text
  18. 18. Solution and Approach ● Add features to manipulate electronic ink into a blog tool to make it easier to handwrite or sketched posts in pen-based devices ● Approach: – Study the blog tool and her architecture – Study technologies to receive data from pen – Implement modules to receive data from pen – Store the data in the database – Implement modules to render the data – Validate using various browsers

  29. 29. InkBlog - Android
  30. 30. Final Considerations ● InkBlog: allow users do handwriting posts and draws sketches to do their activities – We improve the Ae´s Weblog with components to generate and manipulate electronic ink, calling this new tool as InkBlog – We chose well-defined and promising technologies, such as W3C InkML and HTML5 – First version of InkEditor: ● can be integrated with other tools
  31. 31. Future Works ● Do more validation studies mainly in real contexts Humanities Arts Engineering Biology Physics Mathematics
  32. 32. Future Works ● Study the impact of adding other data types – Some tools need access data from other tools. – E .g. the search tools: how to do a search in InkML data? ● Increase the InkEditor functionalities, such as ink selection, copy and paste features ● Implement gesture support
