Overview

Google Glass is a wearable computer with an optical head-mounted display (OHMD) that is being developed by Google in the Project Glass research and development project, with a mission of producing a mass-market ubiquitous computer.

Google Glass displays information in a smartphone-like hands-free format, that can communicate with the Internet via natural language voice commands.Source: http://en.wikipedia.org/wiki/Google_Glass

Location and Sensors

Source: https://developers.google.com/glass/develop/gdk/location-sensors

LocationManager locationManager; // initialized elsewhere

// This example requests fine accuracy and requires altitude, but// these criteria could be whatever you want.Criteria criteria = new Criteria();criteria.setAccuracy(Criteria.ACCURACY_FINE);criteria.setAltitudeRequired(true);

List<String> providers = locationManager.getProviders( criteria, true /* enabledOnly */);

for (String provider : providers) { locationManager.requestLocationUpdates(provider, minTime, minDistance, listener);}

Location and Sensors

The following Android API sensors are supported on Glass:

Sensor.TYPE_ACCELEROMETERSensor.TYPE_GRAVITYSensor.TYPE_GYROSCOPESensor.TYPE_LIGHTSensor.TYPE_LINEAR_ACCELERATIONSensor.TYPE_MAGNETIC_FIELDSensor.TYPE_ORIENTATION (Deprecated, use SensorManager.getOrientation() instead.)Sensor.TYPE_ROTATION_VECTOR

Camera

Source: https://developers.google.com/glass/develop/gdk/location-sensors

You have two options for capturing images or video:

Calling the built-in camera activity with startActivityForResult(). Use this option when possible.

Building your own logic with the Android Camera API. Follow these guidelines if you are using this method:

Take a picture on a camera button click and a video on a long click, just like Glass does.

Indicate to the user whether a picture was taken or a video was recorded. Keep the screen on during capture.
