Augmented Reality (AR) superimposes a virtual Google SketchUp model onto the real world and is only available on the iPad^® 2nd and 3rd generation and iPhone^® 4. AR works because both the iOS device and Google SketchUp model are geolocated. To ensure on-site accuracy, check the following:

• The Google SketchUp file must be geolocated
• On-the-ground location accuracy is increased with a cellular connection - a wifi only connection will have a wider range of error
• If there is no cellular or wifi connection, model can be manually located by tapping, dragging, and further adjusting

• Compass Interference
  • From time to time, the compass may need to be recalibrated to compensate for local magenetic fields. When this calibration is needed you will be presented with a request to move the device in a figure '8' motion. Move the device as instructed to calibrate the compass.
  • If the model appears to be in the wrong location, try moving the device away from any local magentic sources, pressing the Home key, and tapping on the SightSpace icon. This will re-initialize the augmented reality engine with an updated compass heading. Alternately, use the Maps application to ensure your device has you positioned correctly.
• Model Drift
  • Occasionally, the model may appear to drift from its location even though the device is not moving. This can be easily fixed by pressing the Home key and tapping on the SightSpace icon. This will re-initialize the augmented reality engine and re-position the model.

Select the .kmz file in Dropbox, select the Action button in the upper right, and select Open in SightSpace.

On the iPhone, the Action button in the lower right. Tap the action button and select SightSpace.

The .kmz file email attachment will initially show as a Down arrow. Tap the arrow to download the .kmz file to your device.

When the download completes, the file will show with the SightSpace icon.

Tap the icon and select Open in SightSpace

When browsing the Google 3D Warehouse, look for 'View in SightSpace 3D' links associated with the model.

To search for models near your current location, tap the action icon in the upper right of the Google 3D Warehouse. Select a search radius. You can also search for a model near the model currently loaded.

Note: Not all models are available for viewing in SightSpace 3D and those models will not have a 'View in SightSpace 3D' link

• SightSpace 3D reads .KMZ files. Select "Device Models" from the "Load" button to load a Google SketchUp model already on the Device.
  • Load a model onto the device by going to iTunes^® and clicking on the device (e.g. iPad^®, iPhone^®) icon. In the device menu, go to the Apps tab and scroll down until you see "Filesharing". Click on the SightSpace icon and then click Add to select the files.
• Select "Google 3D Warehouse" to open the Google 3D Warehouse and download a model (look for "View in SightSpace 3D" link). Requires internet connection.
• Open .KMZ files from Dropbox by selecting the .kmz file in Dropbox, clicking the Action button in the upper right, and selecting Open in SightSpace.
• Open .KMZ email attachments by tapping the arrow to download the .kmz file to your device. When the download completes, the file will display the SightSpace icon. Tap the icon and select Open in SightSpace

Select "Device Models" from the "Load" button to show all models currently on the device. Tap on a model to load into SightSpace 3D

To delete a model, click the Trashcan, and click the red X icon. Confirm delete.

• Orbit – use a single finger to rotate around the model
• Look Around – use a single finger to look up, down, left and right
• Background – change the model background image to a Photo on the device, a live Camera feed, or set to No Background. Model can be resized and located over the selected background.
• Stereo 3D (Red/Cyan) - View your model in 3D with a pair of red-cyan 3D glasses
• Stereo 3D Exaggeration slider: choose how much to exaggerate your 3D viewing experience when viewed with red-cyan glasses. Slide towards Maximum to increase model "pop" from the screen.

Select + Bookmark icon on toolbar to add a bookmark of the current model view. Select Bookmarks on the Tab bar to view all current model bookmarks. To delete bookmark, tap on trashcan delete button. Bookmarks are associated with the active model.

The camera button takes a photo of what is currently displayed on the screen. These images are stored in the Photos Tab bar item and are associated with the model photographed. An image can be shared by selecting Photos on the Tab bar, choosing the desired photo, and selecting Email Photo under the Action button. Photos may also be Printed or saved to the Photo Album, also under the Action button.

The AR button turns on Augmented Reality mode and is only available on iPad 2nd and 3rd generation, and iPhone 4. The digital Google SketchUp model is positioned in physical space and viewed through the device camera.

If you are not located near the model, you are prompted for a location by receiving a top-down view of the active model and tapping a location (pinch-zoom and single-finger pan to move to desired locale).

Touch controls in AR mode:

• Single finger pan to move the model up, down, left, right
• Pinch-zoom to move forward and back
• Double tap to choose a new location
  • Note: Double tapping for a location will turn off GPS updates. These controls can be used with both a geolocated and non geolocated model.

Note that the model is displayed at real-world scale because it is geolocated and the device has location information. If geolocation is not available, the model is still displayed.

The action menu in the upper left provides additional options:

• Disable GPS Updates - The iOS device continuosly updates its location information. At times, this can result in a model-shift or drifting. If you like the location of your model and dislike the location updates provided, you can turn off the GPS with this option.
• Stereo 3D (Red/Cyan) - Turn on Red/Cyan Stereoscopic 3D, viewable with a pair of red/cyan 3D glasses. 3D stereoscopic model is superimposed over the live camera feed.
• Stereo 3D Exaggeration slider: choose how much to exaggerate your 3D viewing experience when viewed with red-cyan glasses. Slide towards Maximum to increase model "pop" from the screen.

To place a note on the current model, tap location and type. Previously placed notes appear while in Notes view with a yellow bubble.

Share notes by tapping on the note and selecting Email note from the Action button. Notes are emailed with a picture of the note location on the model.

Delete notes by tapping on the note and selecting Delete note from the Action button.

The Photos Tab bar item displays images taken with the Camera button. Photo Actions include the option to Email Photo by selecting the desired image, selecting Email Photo, and emailing the recipient. Print and save to Photo Album are also available.
