INTRODUCING AUGMENTED REALITY AT SECONDARY COLLEGES OF ENGINEERING

  1. 1. INTRODUCING AUGMENTED REALITY AT AUSTRIAN SECONDARY COLLEGES OF ENGINEERING
  2. 2. HTL Austria - Federal Austrian Colleges of Engineering Andreas Probst TU Graz, Austria Graz University of Technology Dept. Educational Technology Martin Ebner Authors
  3. 3. Situation in industry and education @ HTL Decreasing number of students in mechanical and electrical engineering Increasing demand on engineers Engineering Education at Austrian HTL à Increase students interest in Engineering education
  4. 4. Looking at the past – where we came from source: https://de.wikipedia.org/wiki/Rei%C3%9Fbrett#/media/File:Bundesarchiv_Bild_183-70282-0001,_Ingenieure_an_Reissbrettern_(cropped).jpg
  5. 5. Changing situation Drawing board 3D CAD Why should we change anything? 2D CAD AR & IoT
  6. 6. Augmented Reality (AR) – What about? Source: M. Porter and J. Heppelmann Harvard Business Review
  7. 7. AR and IoT with Thingworx / Vuforia Raspberry/Arduino Sensors CAD-data Illustration program WLAN WLAN Mobile device IoT-platform WLAN WLAN Hololens AR and IoT with … @
  8. 8. General engineering education currently using: Blackboards Presentations Books Internet documents CAD data … additionally using AR: à  using mobile devices à fun à  navigating through the 3D models à  getting information about the parts and their functionality à  Q&A directly in AR
  9. 9. AR in engineering design lessons •  Displaying of mounting and dismounting of assemblies. •  Displaying of machines kinematic motion. •  Viewing 3D data within mobile device apps in general. •  Displaying sensor data on the augmented 3D model, which are collected from an IoT application. •  Giving the opportunity to communicate nonverbally à e.g. service case (no manual in English, German, French, Chinese, etc.). •  Start AR within a Thingmark or model tracking + + +
  10. 10. Survey about AR survey parameters 3 HTL with 4 classes attending 4th or 5th (final) year of HTL education 88 students including 6 female students
  11. 11. Survey about AR - Hypotheses H1: The advantages of Augmented Reality are easy to grasp for students. H2: It is easy for students to learn to work with Augmented Reality technologies and tools. H3: Students realize the advantages of Augmented Reality technologies for teaching and lecturing. H4: Students realize the advantages of Augmented Reality technologies for industrial applications. H5: Students enjoy working with Augmented Reality technologies and tools.
  12. 12. Survey questions SQ3: I am familiar with AR technologies and applications. SQ4: I am interested in learning AR technologies. SQ5: AR is useful for better understanding of technical machines and processes. SQ6: AR is a good supplement for understanding industry assembly or maintenance processes. SQ7: Using AR is more attractive to students learning new technical subjects. SQ8: Generating an AR experience was easy to use. SQ9: Using AR is fun.
  13. 13. Survey about AR pre-activity assessment Introduction AR and IoT Students create an AR experience post-activity assessment Google forms by existing document and teacher with Thingworx (Vuforia) Google forms

  16. 16. Conclusion and Outlook Good opportunity to introduce und use AR and IoT into •  curriculum •  engineering design education •  engineering labs •  diploma theses Students •  enjoying working with it •  seems to recognize some potential in these technologies To exclude long-term novelty effects, further investigations in the future are necessary.
