The document discusses augmented reality (AR) and its potential applications in education. It provides an overview of AR, including definitions and examples. The history of AR is explored, from early prototypes in the 1960s-70s to recent consumer adoption on mobile devices. Educational uses of AR are examined, such as visualizing concepts spatially and improving understanding of real environments. The document demonstrates an AR authoring tool called Envisage that allows users to create AR scenes. Future research directions are also outlined, such as improved displays, interaction methods, and educational experiences using AR.

- 38. AR IN EDUCATION
- 39. Benefits of AR for Education • AR can aid Education in a number of ways: • Teaching spatial concepts • Visualizing knowledge objects • Improving literacy and numeracy • Increase understanding of real environment • AR allows students to view and interact with spatial content in a seamless manner • Focus on educational content rather than learning the computer interface
- 40. New Zealand Examples • Geo AR Games • Mobile outdoor gaming • CityViewAR • See historical Christchurch • Quiver • Interactive Colouring Books • Envisage • AR scene creation
- 41. GeoAR Games (iOS/Android) • Outdoor Mobile AR experience • Playing with virtual content in real world • E.g. Sharks in the park – collecting fish, avoiding sharks • Encourages teamwork and physical activity in the real world • http://www.geoar.tech/
- 42. Example:GeoAR Games Magic Park https://www.youtube.com/watch?v=STD1MF51PTw

- 45. Quiver (iOS/Android) • Interactive Colouring Books • Children colour their own AR scenes • Wide range of educational pages available • Animals, cells, volcanos, etc • http://www.quivervision.com/
- 47. Envisage (Windows) • Desktop software for easy authoring of AR scenes • Create your own visual tracking markers • Upload your own 3D content • Create and save educational scenes • www.envisage-ar.com
- 48. HANDS ON WITH ENVISAGE
- 49. Envisage AR Just like how you can use PowerPoint to create multimedia slideshows, you can use Envisage AR to create augmented reality experiences. Bring together your own markers, 3D models, sounds, images, and text to create your own story. From https://envisage-ar.com/shop/ Image Sound 3D Text Abc Marker
- 50. Envisage User Interface Toolbar Scene Tree Configuration Panels 3D / AR View
- 51. Getting Started:Video 1. Select “Video” in the scene tree 2. In the configuration area, select “Camera” 3. Press the green “play” button 4. This dialog box appears – press “OK” 1 2 3 4
- 52. Adding Markers 4. Click “OK” to add the marker 1. Click the “Add Marker” button on the toolbar 2. Click “Browse” 3. Select the pattern file 1 2 3 4
- 53. Adding Markers 2 We now have a tracked marker we can add things to… Notice the grid?
- 54. Adding 3D Models 1. Right click on the newly added marker in the scene tree 2. Select “Add 3D Model” 3. A blue cube appears on the marker
- 55. Adding 3D Models 2 1. Double-click on the new item in the scene tree 2. Select a model file 3. The blue cube is replaced by the new model 1 2 3
- 56. Adjusting Models Now we want to adjust the model. We can change its: - Position: Where it is in relation to the marker - Rotation: Which way it is facing - Scale: How big it is Click on the model to select it. A set of three arrows appears. This is the adjustment tool (widget)
- 57. Adjusting Models 2 The tool has three modes you can select from the toolbar: Translation Rotation Scale To translate the model, drag the axis pointing in the direction you want to go.
- 58. Adjusting Models 3 To rotate the model, click and drag around one of the axes To scale the model, click and drag one of the axes, or on the yellow box.
- 59. Adding Other Things In addition to 3D models, you can also add: - Images - Text - Simple 3D objects (“primitives”) - Sounds
- 60. Images When you add an image, you can select a picture file. e.g. JPG, PNG, BMP It will show up as a rectangle with the picture on it. You can move the rectangle around in the same way as a 3D model.
- 61. Text You can add text and chose what it says. You can move the text around in the same way as a 3D model.
- 62. Primitive Shapes You can add simple shapes, like a box, sphere, or cylinder. You can move the shape around in the same way as a 3D model.
- 63. Sounds When you add a sound, you can select a Wave file. i.e. WAV You can move the speaker around in the same way as a 3D model, to make it sound like it comes from a certain place.
- 64. Training Markers 1. Click the “Marker Training” button on the toolbar 2. Hold your marker up to the camera so you can see the red-green outline 1 3. Click the mouse button 4. Give the marker a filename and save it (“pattern file”) 5. Click the “Marker Training” button again to exit training mode 2 3 4 6
- 65. Tracking Markers You can make your own markers by drawing inside the provided black frames. For your designs to work, they must be: - Bold: avoid fine detail - Different from each other: the computer has to tell them apart - Different from all sides: the computer has to tell which way is up
