  1. 1. OpenSocial in Education and Learning Evgeny Bogdanov May 30, 2011 1/26
  2. 2. Content Educational scenario: now Educational scenario: better Space concept Graaasp as a platform supporting spaces Opensocial gadgets (why and how) Demos Ideas gathering 2/26
  3. 3. Intro: Educational scenario Now: Remote experimentation (Automatic control at EPFL) People Professor Assistants Students Resources Description of experimental setting Instructions Theory book Apps Device in the lab Remote access to device 3/26
  4. 4. Intro: Educational scenario (extended) Extension: Remote experimentation (Automatic control at EPFL) People - social platform → more interaction Professor Assistants Students Resources Description of experimental setting Instructions Theory book External info - Wikipedia, Youtube videos, Slideshare Apps Device in the lab Remote access to device Chat, Visualizations, Recommendations 4/26
  5. 5. Space concept Definition Space is an abstract concept that shapes the context in which user is currently placed. It normally consists of: People Applications Resources Sub-spaces Example A space can represent a group of people, a university course, a company division, a folder, a forum, a blog, etc. Definition Widget or Gadget is a [small] application that can be installed and executed within a web page by an end user (Wikipedia) 5/26
  6. 6. Educational scenario in Graaasp 6/26
  7. 7. OpenSocial gadgets understanding 7/26
  8. 8. Demo: Gadgets and OpenSocial Widgets container (functional skin) Resources viewer widget (youtube, etc.) Recommendations widget (recommendations from Graaasp) Remote lab (functional skin) Remote experimentation widget (gyroscope example) 3D widget (3D pad) 2D widget (graph based on data from assets) OpenApp interwidget communication Chat widget Graaasp’s 3D pad in iGoogle Remote lab in iGoogle 8/26
  9. 9. Functional skin / Bundle: Widget container This functional skin takes all widgets from a space and shows them in a grid layout: two column view. 9/26
  10. 10. Functional skin: Resources player This functional skin, when added to a space, allows to view content of all documents from a space. For example, youtube videos, slideshare presentations, wikipedia, etc. 10/26
  11. 11. Widget: Recommender This is a recommender gadget. When added to a space, it allows to get recommendations for this space. 11/26
  12. 12. Functional skin / Bundle: Remote lab This is an example how functional skin “Widget container” is used. Four widgets are integrated together within a functional skin to provide user with remote lab experience. 12/26
  13. 13. Widget: Remote experimentation (Gyroscope) This gadget shows a rotating gyroscope model. When it is added to a space, it displays people in the space that can collaborate over this gyroscope. 13/26
  14. 14. Functional skin: 3D pad This is a functional skin gadget. When added to a space, it allows to view all items from a space in 3D space. 14/26
  15. 15. Widget: 2D Graph Gadget to display data as graphs. Takes data from assets in a space and shows it on the graph. 15/26
  16. 16. Widget: OpenApp interwidget communication One gadget sends data, another receives it. 16/26
  17. 17. Widget: Chat Chat gadgets allows people to talk to each other. 17/26
  18. 18. Portability: Graaasp’s frozen 3D pad in iGoogle This is a frozen gadget. It is generated in Graaasp and taken to other containers (iGoogle for example). 18/26
  19. 19. Portability: Remote lab functional skin in iGoogle This is a Remote lab widget running in iGoogle. 19/26
  20. 20. REST API http://graaasp.epfl.ch/rest/spaces/4/@person http://graaasp.epfl.ch/rest/applications/4/@space http://graaasp.epfl.ch/rest/documents/4/@person http://graaasp.epfl.ch/rest/people/4/@self/@space http://graaasp.epfl.ch/rest/recommender/4/@person 20/26
  21. 21. RPC API osapi.spaces.get({contextId: “4”, contextType: “@person”}) osapi.applications.get({contextId: “4”, contextType: “@space”}) osapi.documents.get({contextId: “4”, contextType: “@person”}) osapi.recommendations.get({contextId: “4”, contextType: “@space”}) People are a bit different (shindig hack) osapi.people.get({userId: “4”, personId: “@person”, groupId: “@self”}) 21/26
  22. 22. Useful RPC request Get current context (Space or Person) osapi.context.get().execute(function(context){ // context.contextId = "1" // context.contextType = "@space" }); Get current viewer osapi.people.getViewer().execute(function(viewer){ // viewer.id // viewer.displayName }); 22/26
  23. 23. Reminder! Widgets can exchange data with each other Widgets can get data about space containing it Widgets have access to container information: spaces/people/applications/documents Widgets have access to Realtime aspects (collaboration) All other Web stuff is available (2D,3D,calculation,etc.) 23/26
  24. 24. Ideas gathering! Geography scenario: on word selection in w1 show location in w2 widget1: view Geography resource widget2: google map with location History scenario: on word selection in w1 show location in w2 and wikipedia entry in w3 widget1: content viewer (history book) widget2: on word selection show google map with location widget3: wikipedia entry Chemistry widget1: Formula editing widget widget2: 3D view of a molecule Math course widget1: Formula editing widget Remote lab at LA gadget widget1: Formula editing widget2: notes taking tool 24/26
