  5. 5. Interaction design history
  6. 6. Operate the machine <ul><li>“ When programmable-interactive machines first appeared, the creators of their controls and interfaces emphasized the goal of ‘operating the machine’.” </li></ul>Back in the day.. Engineering design-based: make faster and bigger machine People adapt to machine: people speak the machine’s language. No designers involve, but lots of expert engineers.

To create, edit, store and format the text document. </li></ul>S. Rubenstein & J. Barnaby, 1979 A tool for writing
  14. 14. Perform a task <ul><li>“ Previous applications are too complicated. Hence, it invited complaint and competitors ” </li></ul><ul><li>“ The tools had emphasis on ease of learning, ease of use, reduce errors and save time .” </li></ul><ul><li>“ Eventually, professionals emphasis on people doing a task rather than ‘a tool with good control’.” </li></ul>Draw and edit a picture Create printed materials Create a budget Compose music

  26. 26. Interaction design history
  27. 27. What is Tangible Interfaces ?
  28. 28. Tangible interfaces <ul><li>“ Generally graspable and tangible interfaces are systems relating to the use of physical artifacts as representations and controls for digital information&quot; </li></ul>http://www.youtube.com/watch?v=Mgy1S8qymx0
  29. 29. There are 4 characteristics concerning representation and control: <ul><li>Physical representations are computationally coupled to underlying digital  information. </li></ul><ul><li>Physical representations embody mechanisms for interactive control. </li></ul><ul><li>Physical representations are perceptually coupled to actively mediated digital representations. </li></ul><ul><li>Physical state of tangibles embodies key aspects of the digital state of a system. </li></ul>http://vimeo.com/13879559
  30. 30. Tangible interfaces <ul><li>“ Tangible interfaces rely on a balance between physical and digital representations.&quot; </li></ul><ul><li>“ Digital representations are needed to mediate dynamic information.&quot; </li></ul>
  31. 31. Tangible interfaces <ul><li>“ Physical spatiality describes the co-presence of user, objects and other users in one interaction space . This space is a hybrid .&quot; </li></ul><ul><li>“ Haptic directness denotes direct manipulation where the physical, graspable objects themselves are the interface ..&quot; </li></ul>http://www.youtube.com/watch?v=Cog8b8ojji0
  32. 32. Do you want to develop Tangible Interface project ? First, you need to know the project management.
  33. 33. Project management (PM) <ul><li>“ Project management is the discipline of planning, organizing, securing and managing resources to bring about the successful completion of specific project goals and objectives.&quot; </li></ul>
  34. 34. PM Criterion Based on ‘Why IT projects fails ?” Hard Criteria Scope Time Cost Resources Quality Soft Criteria Motivation Leadership Communication Recognition and etc.
  35. 35. Failures : PM in IT Based on ‘Why IT projects fails ?” <ul><li>Unrealistic or unarticulated project goals </li></ul><ul><li>Inaccurate estimates of needed resources </li></ul><ul><li>Badly defined system requirements </li></ul><ul><li>Poor reporting of the project's status </li></ul><ul><li>Unmanaged risks </li></ul><ul><li>Poor communication among customers, developers, and users </li></ul><ul><li>Use of immature technology </li></ul><ul><li>Inability to handle the project's complexity </li></ul><ul><li>Careless development practices </li></ul><ul><li>Poor project management </li></ul><ul><li>Commercial pressures </li></ul>
  36. 36. How to construct the project ? Then I will explain the project outlines.
  37. 37. Multi-Touch ‘Workshop’ <ul><li>“ Introduce to Multi-touch technologies including development, process, management, execution, and evaluation.” </li></ul>
  38. 38. MT ‘Workshop’ <ul><li>The Multi-touch technology software is based on vision tracking. </li></ul><ul><li>We will use Community Core Vision (CCV) and FLASH with AS 3.0 to develop the application. </li></ul><ul><li>The CCV works as bridge between the camera (input) and flash program (output). </li></ul>
  39. 39. MT ‘Workshop’ <ul><li>In developing the multi-touch kiosk/product, several hardware need to be prepared. </li></ul><ul><li>For instance, projector, computer, infrared sensor, camera sensor, glass surface, speaker and others. </li></ul>
  40. 40. What should I do for next step? Prepare the ‘Resources’
  41. 41. Human resource <ul><li>Create a group of 5 members. Each team members will play different role of profession in completing the project. </li></ul>
  42. 42. Rangers (team) Multimedia Technician Multimedia Programmer Interaction Designer Multimedia Designer Industrial Designer <ul><li>Research on user’s experience and interaction. </li></ul><ul><li>Study how user’s interact with the product. </li></ul><ul><li>Eg: UI researcher & designer </li></ul><ul><li>Create back-bone architecture of the application. </li></ul><ul><li>Technical development of the application. </li></ul><ul><li>Eg : Flash programmer </li></ul><ul><li>Develop and organise the information in rich multimedia form. </li></ul><ul><li>Creative in presenting information. </li></ul><ul><li>Eg : Graphic designer </li></ul><ul><li>Develop execute design solutions for physical ergonomics, usability, form and etc. </li></ul><ul><li>Creative in develop fully-functional products. </li></ul><ul><li>Eg : Product designer </li></ul><ul><li>Setup, manage, and fix technical equipments. </li></ul><ul><li>Technical setup of the product to be displayed. </li></ul><ul><li>Eg : Multimedia Technician </li></ul>
  43. 43. Material resource : Input sensor <ul><li>INFRARED WEBCAM </li></ul><ul><li>The best experience in vision tracking especially for this multi-touch project is PS3 EyeCam / ToyCam*. </li></ul><ul><li>However, there are lots of good infrared webcam available in the market. </li></ul><ul><li>* the EyeCam need to be hacked in order to operate as infrared camera. </li></ul>
  44. 44. Material resource : Input sensor <ul><li>INFRARED LIGHTS </li></ul><ul><li>To enhance the detection of contrast between shade and light. </li></ul><ul><li>This light projection will help the camera to tracks ‘finger touched on transparent glass’ </li></ul>
  45. 45. Re-cap : objective <ul><li>History of HCI </li></ul><ul><li>Today’s HCI : environment computing </li></ul><ul><li>Introduction to tangible interface </li></ul><ul><li>IT Project management </li></ul><ul><li>Multi-touch workshop </li></ul>
  46. 46. Any questions ?
