    • Most mind maps applications have their own short comes, and they're not as flexible as drawing on papers. This application is aimed to enhance the user experience of creating mind maps on an iPhone/iPod touch, and to discover new features which we couldn't do by the traditional way.
  1. Lecture Gadget
    • This application is aimed to help students in learning during and after lectures. With this application, students can enjoy a whole new way of notes taking when attending lectures. They will be able to organize their personal notes and hi-lights in the “attach-on-slide way”.
    • A time saving and user-friendly platform that providing course related material and information.
  2. CU Freshmen App
    • The main idea is to tell freshmen the mechanism of “how to get the information” in order to “survive” for the rest of their University life.

Target user

Focus on students in our development.


Mind maps have many applications in personal, family, educational, and business situations, including notetaking, brainstorming (wherein ideas are inserted into the map radially around the center node, without the implicit prioritization that comes from hierarchy or sequential arrangements, and wherein grouping and organizing is reserved for later stages), summarizing, revising, and general clarifying of thoughts. One could listen to a lecture, for example, and take down notes using mind maps for the most important points or keywords. One can also use mind maps as a mnemonic technique or to sort out a complicated idea. Mind maps are also promoted as a way to collaborate in color pen creativity sessions. Mind maps can be used for:

  • Problem Solving
  • Outline / Framework Design
  • Anonymous collaboration.
  • Marriage of words and visuals.
  • Individual expression of creativity.
  • Condensing material into a concise and memorable format.
  • Team building or synergy creating activity.
  • Enhancing work morale.


  • Colorized nodes
  • Drawing/Image attachments
  • Text/Links attachments
  • Audio/Video attachments
  • Updates/Modification notifications
  • Geo-tagging for mind maps

Specification_v2 - Semester 1

  • Not yet decide since there is implementation issue, need further study to decide
  • Text base (xml or custom form)
  • Using CoreData?


  • Single tap on the background to scroll the whole view vertically and horizontally
  • Single tap on the node and drag it to move around
  • Single tap on the node to display preview
  • Single tap on the node and hold for 0.75 sec to enter link creation. After entering the link creation phase, a single tap on another node to create linkage
  • A thumb view for node type selection
  • Double tap on the background to create node
  • Double tap on the node to display the detail view
  • Double tap on the node with deletion on to delete node
  • Pinch to zoom in/out
  • Create nodes by double click with the help of UI (choosing between different kind of nodes)
  • Delete nodes by double click with the help of UI
